Mileage by Brand 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 Brand

So, following quickly on the tail of being asked about comparing the brand and octane rating for mileage, I, of course, got the quite obvious (to the point that I'm not sure how I overlooked it) question of "What about brand and driving type?"

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

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...
