Here you go:I'm trying to search the forums and can't find any suggestions that this is the case.
I'm lucky that most stations in my area are Top Tier. But I also have access to Costco, about 10-12 minutes away. I'm wondering if it's better to go to a Chevron vs Sinclair vs Costco. Just wondering if anyone has actually studied this, or if it's all dogma.
