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.
Do turbocharged engines require premium gas?
Originally Answered: Does turbo car need premium gas? Yes! Turbos generate more heat and boost which contributes to pre-ignition condition of the fuel in the engine. Premium gas is higher octane, so it resists pre-ignition better than regular gas.
Can you use regular gas in a turbo engine?
A: High-octane fuel is used in many turbocharged engines to reduce knock. … These advances have led some manufacturers to allow fuel as low as 87 octane for their turbo engines – even though the engines usually get more power with high-octane. So to answer your question: it depends.
Do turbocharged engines require more maintenance?
It depends on the type of 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 I put regular gas instead of premium?
Using regular gas in an engine that requires premium could void your warranty. That is most likely to happen if using regular causes severe engine knock or pinging (premature ignition of the fuel, also known as detonation) that damages the pistons or other engine parts.
What happens if you put 87 octane in a 93 octane car?

Does premium gas give better mileage?
Premium gas gives you more miles per gallon than regular gas. … In actual fact, you’ll get a greater range of fuel economy between different brands of regular gas, than you will between the same manufacturer’s regular and premium gasses.
How many miles does a turbo last?
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. … Most gas stations that sell 87, 89 and 91 octane gas use what is called a mixer pump.
What is the disadvantage of turbo engine?
To combat fuel efficiency, downsized turbocharged engines have become the new norm. Smaller engines use less fuel, but being turbocharged adds pressure, which can lead to higher temps and engine knock, damaging the engine. To avoid this, you have to have a lower compression ratio.
Do turbos shorten engine life?
Turbos Reduce the Lifespan of an Engine
However, a properly implemented turbo pushing enough PSI through a motor to produce respectable levels of power won’t strain a motor any more than idling in traffic will.
Who makes the most reliable turbo engine?
The study found that six brands have only turbocharged engines with better reliability than the average non-turbo engine. These brands were Honda, Lexus, BMW, Porsche, Audi, and Subaru.
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.”25 мая 2018 г.
Which gas is better 87 89 or 93?

Should I use premium or regular gas?
