This guide is designed to help you find the best oil for your Harley. While H-D supply their own oil, you definitely don't have to utilise it to ensure your Harley runs smoothly.

The chart beneath shows you the recommended engine oil and the corporeality of oil yous demand for each model.

The chances are, your recommended oil will exist 20W50 equally that's the about mutual form for Harleys. Whether yous're running a 103, a Twin Cam or a Softail and whether you run Synthetic or Regular oil, the correct oil will make all the difference.

In air-cooled engine (like the ones found in most Harleys), heat tin be an effect. That's why information technology's often better to choose a constructed-based oil over a mineral (regular) oil as it'll accept amend heat tolerance .

With our oil selector, y'all'll be able to choose a premium oil but save a few quid on the official Harley engine oil.

Nosotros have researched the right oil to the all-time of our power but it goes without saying: ever consult your owner's manual where you lot will find the manufacturer'southward recommended engine oil.

What You Demand To Know

If you improve sympathize the differences between different engine oils, yous'll e'er pick the best ane for your needs and budget.

What'southward the difference between different engine oils?

Mineral oils are refined from petroleum, but even mineral oils contain some constructed compounds or additives to ameliorate them. Semi-constructed oils are a blend of mineral and constructed oils. They have definite improvements over pure mineral oils. Semi-synthetics tin comprise "hydrocracked" bases.

Hydrocracked oils are mineral oils that have been subjected to intense force per unit area and temperature to alter the construction of the molecules, making the resultant oil more stable and resistant to evaporation at college temperatures. Semi-synthetic oils don't toll much more than mineral oils do, but offering advantages over the latter.

Full-synthetic oils, however, are far more expensive than mineral or semi-synthetic oils.  Full-synthetics are human being-fabricated oils that accept been tailored to give them sure advantages like the fact that they perform better in farthermost temperatures, are less likely to evaporate or thin excessively in heat, etc. Full-synthetics contain poly-alpha-olefins (PAO) and esters. PAOs don't gel at depression temperatures, making them necessary for any true 0W oil.

Esters are similar to PAOs but besides help protect metal surfaces and offer skilful lubrication. Full-synthetic oils are expensive and, unless you are racing, not necessarily recommended for motorcycles. For the everyday rider, a semi-synthetic shear-stable 10W-40 oil with some ester content would be a dandy choice.

What's the all-time type of oil to apply for road riding?

Your ideal choice of oil would be an ester semi-synthetic 10W-40 or a 10W-30 that is also shear-stable. The fact that the oil is shear-stable is more important than the fact that it is semi-synthetic.

You are nevertheless better off choosing shear-stable mineral-based oil than a low-quality semi-synthetic one that isn't shear-stable. Only for frequent long-distance riders would the cost of a full-synthetic oil be worth it, every bit it can aid save on oil changes and fuel costs.

Does a high-performance oil produce more ability?

At that place volition ever be loss of engine output due to things like thermodynamics, which can't exist inverse that much. However, some of that loss, near six%, is due to oil drag. By using quality but low viscosity oil, this loss can be minimised and engine power increased. For a typical 100bhp motorcycle, a lighter engine oil might show a 2bhp peak improvement.

Choosing the right oil filter

If you're changing your engine oil, it makes sense to alter the oil filter likewise. An oil filter removes tiny particles from the oil, helping to go on the oil fresher and work to its best ability for longer. A new filter costs a few quid and it simply takes a couple of minutes to change.

We've put together this Harley-Davidson oil filter chart to help you pick the best oil filter for your motorcycle.

How To Change Your Motorbike's Oil

If you've never changed your motorbike's oil earlier, you lot might be apprehensive but y'all needn't be. With the correct tools, anyone can change their engine oil in under an hr. We've put together this simple guide to aid you through your first motorbike oil modify.

Recommended Motorcycle Engine Oils

The table below shows all the different engine oils available for your Harley Davidson engine. We've listed the best motorbike engine oil available, from Mineral-based engine oils to Semi-Constructed, right upwardly to Fully Synthetic,  elevation-quality ester-based oils.

The table has been compiled from owner reviews and ratings and manufacturer-specified oil, where applicable.

What does Engine Oil Exercise?

A good engine oil lubricates, protects, cleans, and cools the engine to continue it running smoothly.

Engine oil provides lubrication betwixt the private engine components, reducing friction. It does so by providing a glace moving-picture show between the moving parts in the running engine. This ensures that the engine can run efficiently, at optimal functioning and with increased power. Lubrication is as well vitally important at showtime-upward. Here, the cold oil in the oil sump needs to be quickly pumped back into the engine so that it can provide lubrication. This allows for an ideal cranking speed to turn over the engine. In guild to ensure that that oil can menses chop-chop at start-upwards, simply also provide enough of a film to protect the engine when running, an engine needs an oil with different viscosity ranges.

Engine oil creates a film on moving parts in the engine, which acts as a protective layer. By preventing and minimising metallic-to-metal contact, wear of these components is reduced. Engine oil has some other way information technology protects the engine. Combustion by-products, oxidation and contamination from condensation all form acids. If left unchecked, these acids can crusade corrosion in the engine, which tin can lead to components failing. Engine oil ensures that this does not happen and then protects the engine.

For an engine to run optimally, it needs to be clean. Deposits in the engine can gum information technology up and reduce its performance. Further, unnecessary vesture and damage in an engine can be acquired by microscopic contaminants.  For perspective, a single pilus is 100 microns thick. Contaminants as pocket-sized as 5 to 20 microns could easily cause damage to an engine. Engine oil keeps the engine clean by holding these contaminants in suspension until they can be removed via the oil filter. Engine oil also prevents damaging deposits from forming.

Finally, engine oil also helps to keep the engine absurd. Heat is caused past the friction between the moving parts likewise as by combustion. The radiator is responsible for cooling the top part of the engine. Cooling the balance of the engine, similar the pistons, rod bearings, timing gears, crankshaft, camshaft etc., is upward to engine oil. Every bit oil passes over these heated surfaces, information technology absorbs the oestrus. This hot oil and so travels to the oil sump, where it is cooled by the air surrounding information technology.

What is Multigrade Oil?

different motorcycle engine oils guide 488x305 - Harley Davidson Engine Oil Selector

Oil is thick and viscous when it is cold so thins as it warms upwards.  Cold thick oil struggles to broadcast as the engine is started, but using a thinner oil here would mean that, once heated, the oil would be too thin to adequately protect the engine.

The answer is using a multigrade oil. This oil, due to the addition of polymer, has two different viscosity grades.  By adding a polymer to a thin oil base, it is possible to have an oil that performs well in both hot and cold atmospheric condition. The polymer ensures that as the oil is heated, the rate of thinning is slowed down. Information technology besides ensures that, as the oil cools, the charge per unit of thickening is slowed as well.

Multigrade oil is identifiable by its ii numbers, say 10W-xl. The get-go number 10W (W stands for Winter) refers to the viscosity of the oil at a depression temperature. A lower number would hateful a thinner oil, so a 5W would be thinner than a 10W. A 0W oil would be the thinnest at cold temperature.

The second number, 40, refers to the viscosity of the oil at a high temperature, which volition always exist measured at 100 °C. Again, a lower number means a thinner oil, so, at 100 °C, a 30 oil would be thinner than the twoscore oil. It is, of form, of import to follow the guidelines of the manufacturer in choosing the correct multigrade oil for your motorbike.

Synthetic Engine Oils Common Questions

We've answered some of the almost common questions when it comes to synthetic motorbike engine oil.

Volition my engine consume more synthetic oil?

Not likely.  In modernistic engines, near oil consumption happens due to evaporation at high temperatures. Constructed oils, all the same, tend to exist far more resistant to evaporation, especially if they comprise ester and PAO, and then oil consumption should be lower with a constructed. Irrelevant of oil blazon, oil consumption volition get up in engines with defective seals, and worn valve guides and piston rings. Here, one might likewise use a cheaper oil instead of a synthetic 1.

Is synthetic oil compatible with other engine oil?

Synthetic oil is fully compatible with whatever other engine oil. Provided the oil is for a four- stroke engine, one can safely mix any type of oil irrelevant of what its base is or what it contains, exist it mineral, semi-synthetic, hydrocracked synthetic, PAO, ester, etc. The exception here would be Castor-oil-based racing oils.

Will a synthetic oil void my warranty?

As long every bit you follow the instructions in your handbook in regards to the viscosity ranges and API of an oil, you can use whichever oil you choose, including synthetics, without affecting your warranty. The choice of brand is likewise up to y'all equally OEMs, by law, cannot prescribe this.

Are constructed oils worth the extra toll?

This depends. For a cracking bike in a nifty condition, the correct constructed oil will help go along maintenance costs downward, lower fuel costs, and keep it running like new.  For an oil-guzzling older model, constructed oils may merely non be worth the toll.

Motorbike Engine Oil FAQ

Can I employ car engine oil in my motorbike?
This can be risky. Even though y'all can and volition find car oil with the same viscosity ratings (i.e. 10w40) every bit for motorcycle engines, the additives in the oil volition exist different. Most cars use a split up gearbox oil and most cars accept a dry clutch. So a car oil could make your clutch slip or knacker your gearbox. If you're ownership a bike that'southward been run on car oil, beware!

Does engine oil have an death date?
Engine oils have an expiry engagement which means the operation levels can no longer exist guaranteed. All the same if your oil hasn't been opened, it'll have years and years for it to degrade. If your oil has been opened and is a couple of years out of date, it'll near likely be absolutely fine. However, if you've already opened it and it's v years out of engagement you'll be better off buying fresh oil every bit the additives in the oil may have oxidised and lost their qualities.

What are the virtually critical areas where the oil flows?
For a motorcycle engine, the critical engine areas are the piston associates, bearings and valve railroad train. The engine oill also lubricates the clutch (simply not if your motorbike has a dry clutch) and your motorcycle's gearbox.

What does my oil filter practice and practice I need to replace it?
The oil filter traps foreign particles and debris that are introduced into the oil by normal riding. These particles can be annihilation from carbon deposits to small metal particles from your motorcycle's engine. These particles can lead to engine damage, while a blocked filter may lead to oil starvation and ultimately engine failure. An oil filter costs simply a few pounds, so information technology makes sense to change this every time you practise an oil change.

What is the difference between a mineral, semi-synthetic, and full-constructed engine oil?
Mineral oils are refined from petroleum, but even mineral oils contain some synthetic compounds or additives to ameliorate them. Semi-synthetic oils are a blend of mineral and synthetic oils. They have definite improvements over pure mineral oils. Semi-synthetics can incorporate "hydrocracked" bases. Hydrocracked oils are mineral oils that have been subjected to intense force per unit area and temperature to change the construction of the molecules, making the resultant oil more stable and resistant to evaporation at higher temperatures. Semi-synthetic oils don't toll much more than mineral oils do, but offering advantages over the latter.

Why does a 2-stroke oil have to be mixed with fuel?
A 2-stroke engine is built and runs differently to a four-stroke ane. A four-stroke engine keeps most of its oil in its crankcase and oil sump and recirculates this oil to lubricate the engine. With a 2-stroke engine, the process is somewhat different. Here, there is no oil sump as the crankcase deals with the compression and induction of the fuel/air mix. The only way, therefore, to provide oil to the engine for lubrication is by calculation it to the fuel. Every bit this oil is burnt with the fuel, it tin't be recirculated. A specific 2-stroke oil is needed every bit 4-stroke oil would leave damaging deposits behind when it burns.

Is any engine oil meliorate than no engine oil?
Yes, simply when it comes to motorcycles, the 'right' engine oil is better than 'whatever' engine oil!

Why do some engines burn oil?
Unfortunately, some types of engines just apply more oil than others due to their pattern. Here, the burnt oil can get out dissentious deposits behind, pregnant these engines frequently need more top overhauls. However, if a touring engine uses more oil than is necessary, changing to a lighter grade of oil often solves the problem.

Can I peak upward my engine with a dissimilar type of oil?
Every bit long as you lot don't mix a 2-stroke oil with a four-stroke oil, you can safely elevation your engine upward with a different type of oil. Yous probably wouldn't want to mix different grades, say, a 5W-30 synthetic with a 20W-fifty mineral oil, but if you practice, it likely wouldn't practise any damage.

Do I need to warm up my engine before riding?
The oil needs to be warm, simply, fifty-fifty amend, hot, especially when riding at speed. When common cold oil is pumped into an engine, cavitation (bubbles of vacuum within the oil) is probable to occur. This, in essence, means that the engine does not receive enough oil for it to run optimally at speed. Warmer, and then thinner, oil ensures that the engine not only receives enough oil, but that all moving parts within it tin piece of work optimally. Ideally, use a 5W-40 or 10W-40 oil and ensure the engine warms up properly for a few km before speeding upward.

Do I demand to regularly change my oil?
If yous tend to drive short distances with a low annual mileage, regular oil changes are vital, irrelevant of whether the minimum mileage for an oil change was reached or not. H2o vapour and fuel tend to make their fashion into the oil, and, unless y'all drive long distances, they never accept the gamble to evaporate. This can cause damages similar corrosion, gear tooth pitting, and band and diameter wear. Long-distance riders with a high annual mileage who use a high-quality oil can afford to exist a lilliputian more than relaxed on the oil changes.

What's the best type of oil to use in a road bike?
Your platonic choice of oil would be an ester semi-synthetic 10W-twoscore or a 10W-30 that is too shear-stable. The fact that the oil is shear-stable is more important than the fact that it is semi-synthetic. You are nonetheless better off choosing shear-stable mineral-based oil than a low-quality semi-synthetic one that isn't shear-stable. Only for frequent long-distance riders would the cost of a full-constructed oil be worth it, equally it can help salve on oil changes and fuel costs.

How does oil 'cling' onto the engine's internals?
Where at that place is high-speed rotation in the engine, due east.m. with a manifestly begetting, the high speed draws a thick layer of oil between the 2 surfaces, like a wedge. Here, this oil supports and carries the load of these surfaces. Every bit soon equally the spinning stops, notwithstanding, either due to the slowing downwards or stopping of the engine, this wedged oil gives fashion. Where no rotation occurs in an engine, oil cannot form this thick wedged layer to protect metallic surfaces. Here, oil provides a sparse protective film and often relies on anti-wear agents, detergents, and anti-oxidant chemicals to assist protect from metallic-to-metal contact.

Engine Oil Glossary

When it comes to motorbike engine oil, there are a lot of terms that become thrown around. We've created this quick glossary to assistance you understand what everything means.

Anti-Habiliment Agent
In boundary lubrication conditions, this condiment reduces the corporeality of wear caused by metal-to-metallic contact by chemically reacting with the metal surfaces and forming a film between them.

Corrosion Inhibitor
This engine oil condiment helps to protect metal surfaces by inhibiting corrosion caused past contaminants. It usually does then through a chemical reaction that forms a protective moving picture over the metal surfaces.

Detergent
This engine oil condiment chemically reacts with acidic, sludge-forming contaminants in the oil to neutralise them. It then holds these, now harmless, impurities in break.

Hydrocracking
Using hydrogen, the hydrocarbons in mineral oil are put under high temperature and pressure to crack their molecules. The result is a synthetic-like base of operations stock of high quality. When blended with further additives, hydrocracked oil is not only extremely stable but as well comparable in functioning to synthetic oils.

Oxidation inhibitor
This additive prolongs the storage life of engine oil. It does so by helping to annul the negative effects of oxidation.

Synthetic lubricant
The base oils for synthetic lubricants are artificially made from chemical compounds or polymerisation of hydrocarbons, instead of by refining petroleum. Synthetic oils offer several advantages over mineral oils.

Viscosity
Viscosity refers to a fluid's resistance to menstruation. Temperature straight impacts the viscosity of the oil. Cold oil is thicker and hot oil is thinner.  An engine oil, withal, needs to exist able to adequately protect and lubricate an engine both at start-up, when it is cold and while running, when it is hot. The solution hither is an oil with 2 different viscosity grades, i.e. a multigrade oil.
