WOW....did I miss something here!! In the past 2 years +plus I put soooo much work into my Boxster....you name it I fixed it(sort of)! This whole time I've been using regular Gasoline....Am I supposed to be running it with premium gas. Can't believe I didn't get that memo. I've even been tracking it.....maybe my lap times will get better!!!
Curious to see what happens with 91 octane. Never had any knocking but I do get a CEL occasionally for both banks running too rich(DME leaning out the engine) Thanks V
