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.
Do turbocharged engines require premium gas?
Engines with high compression ratios or turbochargers often require high octane fuel found in premium gas for optimal performance and fuel efficiency. However, the majority of cars on the road today are optimized to run on regular gas.
Can you use regular gas in a turbo engine?
Modern turbo engines are different, though. … If a manufacturer says you can run regular fuel, the engine will be safe, but you might still find gains from running high-octane.
What happens if I use regular gas instead of premium?
Because regular has lower octane, it is more prone to detonation. Burning regular in an engine designed for premium on a long-term basis or under heavy loads can cause engine knock, and that in turn can damage the pistons, valves or spark plugs.
Does premium gas make a difference?
Premium gives better gas mileage
Because premium gas has a higher octane rating than midgrade or regular gas, it produces a little more power when burnt. Designed for performance cars with large, powerful engines, premium also helps minimize the risk of preignition inside highly-stressed, hot engine cylinders.
Do turbocharged engines require more maintenance?
Do turbocharged cars require more maintenance? … Turbocharged engines will require more frequent oil changes and fresh spark plugs, though turbo engines typically don’t require additional service compared to naturally aspirated engines.
What happens if you put 87 octane in a 93 octane car?
If you usually fill your tank up with 87-octane gasoline and you accidentally put in a higher octane blend (say, 91, 92, or 93), don’t worry. You’re actually filling your car or truck with a different blend of gas, which means it will burn differently in your engine.
What happens if you mix 87 and 89 gas?
Yes. You will not harm your car by mixing different octane grades of the same gasoline providing your car’s engine is designed to run on less than 89 octane fuel and you are not using E85 in a non-E85 compatible engine. 50% 87 octane gas mixed with 50% 89 octane gas makes 88 octane gas. … Fuel is fuel.
Is premium gas really worth it?
Typically, high-performance cars require premium, because their engines have higher compression ratios, while other cars can run just fine on lower octane gas. … The FTC sums it up this way: “In most cases, using a higher octane gasoline than your owner’s manual recommends offers absolutely no benefit.”
Is it bad to mix gas from different stations?
No, getting gas from different gas stations will not hurt your car at all. You need to consult your owner’s manual about what kind of fuel your car requires. … Going to different stations doesn’t matter, but you should try your best not to mix up the types of fuel.
