I've been using Unocal 76 gas to all my vehicles and I remember when the money was really tight (Unemployed) few years ago, I used Costco twice to fill up my Suburban and my Ram 1500 (this is before the Boxster and my Benz')...dude, I did save .$25 cents per gallon but it cost me hundreds of dollars to fix the Suburban. Never again will use different brand...Im not saying Costco is a bad gas but just sharing my experience :cheers:

I am a big fan of Costco and I don't use their gas. I have had issues in the past requiring the use of a fuel line cleaner.

No issues since I moved to Chevron exclusively.

What he said. And don't use that cheap gas on your nice expensive sports car. I also ONLY use Chevron. It has "techtron" added. Helps keep your engine clean. Shell also has something similar. All gas is not created equal. ;)
