Engine Performance problem
2009 Pontiac G6 6 cyl Front Wheel Drive Automatic 28,000 miles
I'm very curious because I've been hearing many different opinions about what type of gas I should use.
I have a 2009 Pontiac G6 GT V6. Is it best to use 87 or 93 octane. Some have told me that it's probably designed to run on 87 so 93 could hurt the engine. Others swear by premium fuel no matter what. What is your opinion?
Thank you in advance.
have the same problem?
