I have quite the opposite. I cannot find top tier unless I travel way out of my way. I just found an Exxon station close to my new office. I'll try and use that for now. In the meantime I was throwing in Techron every 2-3k miles.

I try to stick to Shell if I can help it. Shell is Top Tier and I find their stations are usually better than average. I consider other Top Tier stations, or Sunoco acceptable substitutes if required. Everything else I am using under protest.

You know, Ferrari uses Shell fuel in their F1 cars.

All majors are Top Tier as far as I know. Many cut rate gasolines are also Top Tier. I believe you can find them at www.toptier.com .. Those who say Top Tier isn't about the octane, it's about the detergency are correct. At least there are a few things you can use to evaluate your gasoline. I drive a diesel now and BWM wants 51 cetane diesel. Nobody in the US claims to have 51 cetane diesel. In fact there's very little out there about diesel.

You live in OR, a CA emissions state. Part of that requires that stations have the CA formula diesel. It's a weird specification (based upon aromatics, etc), but the result is that it's very close to 51 cetane.

Cetane is overrated as a performance standard, btw.
