Hello, I just got back from a trip to Seattle from Calgary viva Idaho.
I only saw #2 diesel Lots of places to get fuel. Some of the highway stops have a bigger noxell for the big rigs, it works but just go slow as it will spill back at you
More Important is that the pump has easy access for you to be able to get in and out with out
any problems.
I take 4 -20 litre jerry cans of fuel for a couple of reasons, so I can get though BC with out having to purchase fuel,
So I don't always have to exit the main freeway in the USA to get fuel, I always see the station after the off ramp.
I can plan a pit stop and fill my fuel when and where I want.
Drive safe and have fun
