It depends on the situation, but mixing regular and premium gas is typically not detrimental to newer engines. Answer your questions like is it bad to mix premium and regular gas, what’s the difference between regular and premium, and more with the Land Rover Charleston service team.

 

The Difference Between Premium and Regular Gas

The first thing you need to know about the difference between premium and regular gas is in regards to the Octane Rating. The octane rating is the likelihood of mistimed combustion. The higher the octane rating the less likely the chance of misfiring. Pre-ignition or engine knocks occur when there are these misfirings. Higher octane fuel prevents engine knock, which isn’t an issue if it happens infrequently, but can cause damage in the long run. Typically, premium gasoline, which is higher octane, is either 91 or 93. Regular gas has an octane rating of 87.

Is it Bad to Mix Premium and Regular Gas?

In older vehicles, mixing regular and premium gas would’ve caused serious engine knocking, and would have happened rapidly. Nowadays, engines are more adaptable to the variety. Is it bad to mix premium and regular gas? Well, not necessarily. If your car requires premium to run smoothly, but you aren’t able to find a station with premium gasoline, it won’t hurt to top off with regular gasoline. You do want to avoid running on regular gasoline for extended periods of time.

There are a variety of reasons your vehicle may need premium gas. Mixing regular and premium gas may be bad if you have a turbocharged engine, which requires higher octane fuels to operate properly, or maybe you opted for a high-performance car with a high strung engine that operates with tight tolerances
