No, all later model Harleys run on low octane fuel.
there is a check valve in the oil system that is stuck open over filling the oil tank will cause the dipstick to blow out of oiltank
It's a Harley. Notorious for hard neutral.
If it filled completely it can cause excess pressure and leak over into the combustion chamber. If the level is below the return fitting it should be ok.
The owner's manual suggests a rating of 91 octane and further comments that 87 can be used but could cause knocking in the engine.
Yes, it could.
Possibly but fyi most jet fuels are mostly like diesel, i.e. they have a much LOWER octane rating. Avgas is the exception
Oh, dude, in the last episode of MASH, BJ Hunnicutt rode a Harley-Davidson Sportster. It's like the classic bad boy of motorcycles, perfect for a rebel with a cause like BJ. I mean, who wouldn't want to ride off into the sunset on a Harley?
Use exactly what your owner's manual states. If it says 89 or 91 octane then do not use 87 octane. Using a lower octane that required may cause pre-detonation or what is commonly called (Pinging). Pinging may be harmful and may cause engine damage. Bottom line is to use no lower or higher octane fuel that the engine was designed to run on. Using a lower octane can cause engine damage, and using a higher octane is a waste of money that will provide not benefits whatsoever, and is nothing more than a myth.
87 Octane Regular. Using any higher octane is a total waste of money and will provide no benefit whatsoever. In fact it may cause hard starting. Use only 87 Octane.
Using 95 octane fuel in an engine designed for 92 octane will not cause overheating. Higher octane fuel can actually improve performance and prevent knocking, as it is more resistant to premature ignition. However, if the engine is not tuned for the higher octane, any benefits may be minimal, and overheating is more likely linked to other factors such as cooling system issues or engine load rather than fuel octane rating.
Yes, you can use 87 octane fuel in a 2008 Infiniti G35, but it is not recommended. The vehicle is designed to run optimally on premium fuel (91 octane or higher), which helps ensure better performance, fuel efficiency, and engine longevity. While using 87 octane may not cause immediate damage, it could lead to reduced power and efficiency over time.
The same gasoline you use in domestic cars. Just be sure and use the octane recommended by the manufacture. Do not use a higher octane than is recommended. Doing so, is a waste of money and will provide no benefit whatsoever. Also do not use a lower octane or you may cause pre-detonation which could result in engine damage.
