Costco's gasoline actually meets the same standards that are set by "Top Tier" license, which, if you review the list of gasoline brands licensed by Top Tier (https://www.toptiergas.com/licensedbrands/) you will see all the major brand names, including but not limited to 76, Chevron, Mobil, Shell, Texaco... etc!
never try it.
It's always good quality gas!
Have a friend that is a manager for Costco and said that it is good quality gas and fresher because they have to fill there main tanks several times a week due to so many customers vs gas stations. They do a huge volume.
I think it is great quality
I get about 30 miles more per tank full compared to Shell and Chevron. I have never compared it against Mobil
Yeah, the quality is excellent, besides being the best deal anywhere, especially with 4% rebate!
Yes, their gas has conditioners in it and is of good quality. They routinely have theirs tested to make sure.
