Hey guys. I have a 95 M6 and I put in 10 bucks of the cheap 87 Octane gas last night by mistake. I have never put in anything less than 91 before. Is this something I should be concerned with? Do I need to get that stuff out of there?

Thanks,
Asim

 

Don’t worry about it. Just fill the rest of the tank with premium next time you get a chance. All premium really does is prevent knocking when you really get on it. At worst you might see a little less performance at WOT.

 

Not a problem just burn it out of there and move on.
