Is it OK to use 91 octane?

“Use 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. Some manufacturers recommend premium gas but say that regular or mid-grade gas can be used instead.

What happens if you put premium gas in a old car?

In older cars that require premium, The Drive reported fueling with 87 octane would almost immediately cause the engine to start knocking. “If you mistakenly fill up with regular fuel, your car’s ECU will adjust engine timing and performance to work with the lower-octane fuel,” The Drive said.

What happens if you put 98 instead of 91?

It can’t hurt your engine if you use a higher octane fuel. So, for example, if you use 95 or 98 in an engine designed for 91, that’s OK. However, it’s not acceptable to put in a lower octane fuel than the minimum recommended by the manufacturer. Using 91 in an engine designed for 95 or 98 is potentially destructive.
