What happens if you use 87 instead of 91?

\u201cUse premium unleaded gasoline with a posted octane rating of 91 or higher. If the octane rating is less than 91, you could damage the engine and may void your vehicle warranty. If heavy knocking is heard when using gasoline rated at 91 octane or higher, the engine needs service.\u201d

What kind of gas do rental cars use?

Unless the rental car company specified using premium fuel, it's okay to use regular gas. The only time you need to use premium is if your car's manual requires it. If the car runs on regular gas (87 octane), there's no benefit to using the costlier premium gas.

What happens if you put 91 octane in a 95 octane car?

If 91 octane petrol is used in these cars, they run the risk of pre-igniting or "knocking" - that's when the petrol combusts early and pushes down against a piston while it is still moving upwards during the compression stroke. And that can cause serious damage. That's the bad news.

How long can 93 octane gas sit?

\u201c93-octane fuels are more refined and contain more stable hydrocarbons. These stable hydrocarbons can last two to three times longer than those in 87-octane fuel. Even with proper storage, 87-octane gas can start to degrade in three months; 93-octane fuel should last closer to 9 months before degradation is noticeable.
