I just signed up and will give it a try. Some of the web reviews are pretty good. There are quite a few gas stations in my area with good savings. There are a lot of restaurants, but none that I frequent.
I’m the same way but mostly because We don’t eat out or do pickup/delivery that much.
Check it out and see if it works for You, let Me know what You think.
I could have really used it back in the day when I was driving a ‘77 Suburban, 454, Rochester 4 BBL, Dual A/C and twin fuel tanks. IIRC the tanks were 32 gallon main and 16 gallon auxiliary and it’s a damned good thing that Aircraft Carrier got 7 mpg cruising in town or highway and 4 mpg towing uphill/downhill, headwind, tailwind, crosswind, A/C on or off, it made no difference to it.
There were times when I should have just taken off the air cleaner cover and held the pump nozzle right into the intake manifold.
