I use Gas Buddy to find fuel but have one particular filter I use and never vary. I prefer Top Tier gasoline and won't buy from a station that doesn't have it, if I have to spend a couple of more cents that's ok with me. There is a difference in fuels and Top Tier fuel is IMHO much better for my engine, I run it in everything including my lawnmower.
If you don't know about Top Tier check out their website.
