Is higher octane gas better for turbo engines?
The higher the octane rating, the greater the resistance to preignition, the fundamental cause of engine knock. As automakers produce more vehicles with turbocharged engines, it is likely they will recommend or require more LDVs to use higher-octane gasoline.
Why do Turbos need higher octane?
Fuel with a higher octane rating can stand up to higher compression before it detonates. Engines with high compression ratios or turbochargers often require high octane fuel found in premium gas for optimal performance and fuel efficiency.
Why do turbocharged cars need higher octane fuel?
The reason is that when in boost conditions, the turbocharger increases engine compression to a point where regular 87 octane fuel may pre-ignite and cause pinging and knocking. To solve this, some car manufacturers will recommend higher octane fuel which is more resistant to re-ignition.
Can you use lower octane fuel in normal engine?
If you put this fuel in a “normal” engine, it may even have detrimental effects, since the engine will have a harder time combusting the higher octane fuel. Even if your car requests a higher octane fuel, it may be possible to use a lower octane fuel because of variable timing and other magic. Your manual would state that.
Why is it important to use high octane gas?
In these cases, a higher octane fuel helps resist engine knock and allows the engine to operate closer to its normal conditions rather than detuning to prevent engine knock. For best performance, use the fuel recommended in your vehicle owner’s manual.
What happens when you use regular gas in a turbo?
If you use regular fuel in a turbo, in very simply terms the engine will not operate like it was designed to do- period. You also paid big bucks for that turbo why would you skimp now at the gas pump and take a chance on a big repair bill later. Also, your not getting your moneys worth. It’s way to complex to discuss.
