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.

Brand	Driving Type	Number of Entries	Average MPG
Amoco	Highway	12	25.11
Cennex	City	121	14.97
Cennex	Highway	205	23.19
Cennex	Mixed	114	21.45
Citgo	Highway	12	22.44
Conoco	City	171	14.51
Conoco	Highway	144	23.74
Conoco	Mixed	97	19.93
Exxon	City	93	15.5
Exxon	Highway	128	23.35
Exxon	Mixed	106	20.33
Holiday	City	48	15.99
Holiday	Highway	70	22.39
Holiday	Mixed	80	19.29
Safeway	Highway	35	21.62
Sinclair	City	25	15.87
Sinclair	Highway	20	24.54
Sinclair	Mixed	23	21.49

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...
