It can, ultimately. It will ruin the plugs and valves, the compression ratio will not be correct, thermal transfer will be to high. The timing will be wrong. It will not be efficient. The small amount of extra HP is not worth the expence when it goes wrong
Wastes money.
is safer for the environment
Using an octane rating higher than your vehicle requires generally does not provide significant benefits and may be a waste of money. Most vehicles are designed to run efficiently on regular octane levels, and higher octane fuel typically only benefits high-performance engines that require it to prevent knocking. In such cases, using a higher octane fuel can improve performance and efficiency, but for standard vehicles, it usually offers no noticeable difference. Overall, it's best to follow the manufacturer's recommendations for fuel octane.
Detonation, also referred to as knocking in gasoline engines happens when the gasoline vapor in the cylinder ignites prematurely before the piston is in an optimum position in the cylinder, usually, slightly before the piston has reached it maximum extension in the cylinder (referred to as BTDC - before top dead center). The solution is to try using a higher octane of gasoline as the higher octane slows the burning of the gasoline. If you are already using a 93 or 94 octane gasoline, take your vehicle to your friendly mechanic. As there may be other issues involved such as the incorrect timing of the engine.
Yes, you can use 87 octane fuel in a 2005 Volvo XC90 with a 6-cylinder engine, as it is designed to run on regular unleaded gasoline. However, using a higher octane fuel may provide slightly better performance and efficiency. Always refer to the owner's manual for specific recommendations and requirements for your vehicle.
Use the lowest octane that does not 'ping' (detonation). The higher octane is not only more expensive, it can, in some cases, cost you performance. Its got to do with things like the latent heat of vaporization and other scientific formulas.
Using an octane rated lower than your vehicle specification will damage the engine. I would recommend not doing that.
If vehicle does not "ping" severly on acceleration - no advantage
Yes, you can mix 87 octane gasoline with 93 octane gasoline without any issues. The resulting octane rating will be somewhere between the two, depending on the proportions mixed. However, using a higher octane fuel than required for your vehicle may not provide any additional benefits in terms of performance or efficiency. Always refer to your vehicle's owner manual for the recommended fuel octane rating.
A 3vze engine will take anywhere from regular 87 octane, up to 100 octane race gas. However what is your purpose to using higher or lower octane, Using regular, plus, or premium will work well. however higher mile engines would prefer 91 octane!
87 octane regular is recommended. Using a higher octane is a total waste of money and will provide no benefits whatsoever.
Using octane fuel higher than your car is rated generally has minimal impact on performance or efficiency. Most modern engines are designed to run optimally on the recommended octane level, and using a higher octane fuel may not provide any noticeable benefits. However, it can help prevent knocking in high-performance or modified engines that require higher octane. In most cases, it's an unnecessary expense without significant advantages for standard vehicles.
