Oldsmobile/Buick: 1978 Regal

Question
Hello,

I've got the opportunity to purchase a 1978 Buick Reagal 3.8l, What octane fuel are these designed to run on?

 Thanks,Jim

Answer
Jim,

Good afternoon. My apologies for the late response. From what I've read online the manual recommended a minimum of 87 Octane. Inherit benefits of using mid grade, premium octanes or additives are speculative as to whether or not there is a benefit.

Jim, I hope this helps. If you have any more questions please feel free to ask. Don't forget to rate my response to you.

Thanks,
