Should I use 87 octane 91?
The main difference with premium is its octane rating — 91 or higher compared with 87 for regular octane. The higher octane gives premium gas greater resistance to early fuel ignition, which can result in potential damage, sometimes accompanied by audible engine knocking or pinging.
Is it better to use 89 gas instead of 87?
Using a higher octane than necessary If you opt for a higher octane than your manual recommends—say, 89 instead of 87—your car will be perfectly fine, an article on AAMCO’s blog explains. It will not, however, improve your car’s mileage or give it any sort of extra performance boost, according to Car Talk.
Can I put 89 octane in a car that requires 91 octane?
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.

Can I use octane booster instead of premium gas?
If you want high-quality octane fuel, you should be ready to pay for it. Octane boosters will work out only for high compression engines like a sports car. Race cars and performance cars are designed to run on high-octane fuels because these types of fuels can generate power.
Do turbo 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.
