I just noted this in another thread about "where do you buy fuel". At Thanksgiving, we passed two Flying J's on California Hwy 99 that had fuel at one for 35 cents a gallon more than stations at the next off ramp and another that was 40 cents more a gallon.
I just don't get the love affair some have with buying fuel at truck stops. Higher prices, dirty islands and grumpy truckers. I'm 65' long and buy my fuel at local stations. Most modern stations have large islands and easy access.
My choice for best fuel prices are, Indian Casinos, brand names such as Shell, Chevron, Mobil and some local types like Sinclair and Maverick. Truck stops are my last choice and Gas Buddy is your friend. Many may not know, but when you find a station on Gas Buddy, they will often have a photo of the station giving a good idea about size and access.
