Really depends on what you believe… i try to fuel up strictly at shell stations because i like the air miles…. The only place i avoid fulling up at is reservations the native fuel is cheap and from low grade suppliers here as they do not have the same regulations as other fuel stationsIs all diesel fuel the same? Do different companies use different additive? My local station uses schaeffers. Any fuel better than the rest?
Some stations "claim" to have better additive packages but who really knows? I usually use Circle K and the truck does seem to get slightly better mileage then when I use other brands but it's splitting hairs really. From what I understand Circle K uses Shell as they have some sort of connection (parent company)
