Hey guys I hear so much BS on these forums about things people think they know. Does anyone actually know the facts about costco gas? There is a costco that just started selling gas for about 15 cents cheaper for premium gas and I have been filling my G up for a few months now. i don't notice anything now but will it cause any damage later on? Is it cheaper quality for the same octane?

Thanks.

 

Totally fine. Been running Costco gas for years in my vehicles.

 

Yes, your engine will detonate and won't be covered by warranty. Horrible decision IMO

 

IMO it isnt wprth the 20 min wait for the few dollars saved ...and i dont trust it i dont noe why....i fill up at petro-canada and have a 5c/liter off car
