Mileage by Fuel Grade and Type of Driving for My 1976 Toyota Celica

Gas Mileage

Here's some interesting trivia about gas mileage. Have you ever wondered which brand, grade, or octane rating gives better gas mileage? Well, I've collected thousands of miles of data on a wide variety of brands, octane ratings, grades, etc. All this information is from my 1976 Toyota Celica. I have found these results interesting, I hope you do as well.


Driving Type by Fuel Grade

Well, after being asked about brand and octane rating, and then about brand and driving type, I figured the next obvious one to address was grade and driving type. So, before anyone asks...

Only combinations that have been recorded more than 10 times are listed to try to eliminate deviant results.

Super Unleaded Mixed 72 20.07
Unleaded Plus City 60 15.03

I, of course, make no guarantees about what kind of gas mileage you may receive in your vehicle, even if it is a '76 Celica with a 20R and nearly half a million miles under the hood, because there are way too many variables that come into play...
