What kind of gas should I run in my Harley?

What kind of gas should I run in my Harley?

Every engine manufacturer specifies a minimum octane rating requirement for fuel. The majority of motorcycle engines, including all current Harley-Davidson engines, require 91 octane or higher (Premium) fuel, thanks to high compression ratios.

Can you run 93 octane in a Harley?

Race fuel (100 to 110 octane and higher) should be reserved to race motorcycles or motorcycles with high compression engines. Since most Harleys today are recommended to run on 91 octane fuel or higher, the 91 to 93 octane range is considered the best.

What happens if I put regular gas in my motorcycle?

This can happen due to heat and pressure. Detonation from time to time will probably not affect your engine. However, if this is frequently occurring, you could end up with some engine damage. Higher octane in fuel means that it will only ignite with very high temperatures and pressures.

What is the best gasoline for motorcycles?

Pure Unleaded Fuel: Most motorcycle manufacturers recommend owners to use pure gasoline in their motorcycles. Unleaded fuel provides the best performance and efficiency in all motorcycle ratings.

Can I put premium gas in my motorcycle?

Regular fuel will be about 87 octane, and premium may range between 91 to 94. If your motorcycle manual recommends unleaded fuel with 87 octane, there is no benefit of going with premium fuel. So if your motorcycle’s manual says premium—use premium fuel.

Why do Harleys have 2 gas caps?

So, you had two tanks, one for oil and one for gas. It evolved to two gas tanks when contained oil systems became the norm (maybe because two small gas tanks were easier to manufacture than one big one?). Now, it’s purely a styling and heritage exercise.

What fuel does bike use?

The numerous Octane gasoline ratings are 87, 88, 89, 90, 91, 93, and 97, symbolizing purity and sophistication in rising order. At one end we have 87 octanes that you use for your bike as unleaded and on the other side, we have 97 octanes that fuel the superbikes sold in India as Speed 97.

Can I put 93 in my motorcycle?

Fuel grade needs to match an engine’s state of tune. Even then, unless your engine is knocking on 87 octane, it’s not going to make more power or run any better on 89 or 93. On the flip side, if you’re thinking of going cheap and putting regular in a bike designed to burn premium, you’re at risk of engine damage.

What kind of gas does a Harley Davidson use?

Many Harley-Davidson owners have asked if they can use 87 octane gas in their motorcycles. Harley-Davidson advises owners of all fuel-injected models to use premium unleaded gasoline.

Is it OK to use ethanol on a Harley Davidson?

Therefore, using ethanol gas will not harm your Harley’s parts. The only way your Harley may have problems with ethanol gas is if it is an older model. Harley-Davidson didn’t design its earlier models to run on ethanol-based gasoline as it does on new models. In such instances, E10 may cause fuel-system components to wear out.

What should the compression ratio be on a Harley Davidson?

There is no official standard, but most motorcycle riders consider a ratio of 10:1 or higher as “high compression”. For sake of argument here are compression ratios on various 2014 Harley-Davidson engines…

Is it possible to calculate fuel efficiency on a motorcycle?

Unlike automobiles, motorcycle Fuel Efficiency is extremely difficult to calculate and it is important to remember these numbers are general guidelines as what to expect under the exact same conditions.
