best and worst mpg

[jdmwannabe]

I got 22 city/highway combined with mods. 24city 31highway bone stock. BTW Blackpearl2006 wondered how much drag the mirrors caused, with my PFM's on I flipped them in on the highway and gained 1mph, 1/2mpg better, it technically was ok because I flipped them out anytime I saw a cop lol
BTW my worst ever was 14mpg, my car also has 232,000 on it so that may not help

I'm testing a blend of 3oz acetone, 1.5oz xylene, and 1.5oz 2stroke oil (shaken, not stirred) added to a full tank. I don't expect much until the gas goes back to non-ethanol, it does seem to run better already though.

24.6486197 with a 90 CB7, over the course of 2 years. I have a roof rack and a pretty good tune-up. Totally stock. I keep methodical track of my mileage and gas purchase.

Have you noticed a diference between the brands of gas out there?

[CB7Man]

Yea, Shell and 76 both sell nice gas
My car started idleing and starting smootherwhen I used thier gas, however they are normally 20-30cents more a gallon. Which doesn't warrant the price, except on race night
My highest was 35 mpg with 95% highway
Lowest was like 15mph full WOT action
1990 LX F22A1 Auto Tranny

Highest was 27mpg in city (that's all I ever drive).
Lowest was 19mpg in city, lots of racing.

I have a 93 LX, F22A1, H23 intake manifold w/IABs, additional IAB spacer, stock intake, 2.25" catback magnaflow, and an automatic transmission, all with 250,000 on original engine/trans.

I believe the worst I measured was a hair below 28. Best was either 34 or just short of it. Winter is 28-30, summer 30-33.

Mostly stock LX, manual, slightly lowered, modified intake

I've never, in over three years, been able to crack the 30mpg barrier,maybe 'cause it's a wagon...not sure.

Is it common that the H gets better mpg? I always thought it'd be worse. If the H does get better mpg, man, what even better reason to get a transplant!

Or is it because of the m2b4 tranny?

Yeah, like 2.2litrebeater said, the h22 is a lot fresher than the f22. Also, I'd really think the (leaner) tune on the h22 is netting me better mpg.

Any h22 tranny is kind of an anti-mpg. I get a lot of passengers thinking/asking "why are you in third gear at cruising speed?!" Then I explain the wonders of short geared transmissions and that I'm actually in fifth.

[ChillPhatCat]

Worst I've gotten was 19... best was 36 doing 65 for about 6 hours straight.

I get 23 MPG driving back and forth from work about 2 miles away.

[90goldcoupe]

My best was 36.88mpg that was in my 90 DX Manual F22B running on the pt3 ecu, I got like 520 miles on that tank and only put about 14 gallons back to fill up. I think that was a fluke cause on the next three tanks I got 33.3-34.4mpg with the same driving. I haven't checked my gas mileage since I got my p39 though. My worst was like 23mpg with my 240,000 mile f22a1.

[Dhorn33]

Since buying my 93 EX sedan 5spd last January I have averaged 26 mpg with a mix of highway and city driving commuting to and from work. The best I got was driving all highway at 70-75 mph on the highway to my cabin when I got 32. The mpg over the winter has been consistently 2-3 mpg less than it is in the summer based on a spreadsheet I have kept since buying the car. It has 193k miles on it and it is 100% stock.

[doylna]

I can't believe that you guys are really averaging anywhere close to 30 MPG. Taking the average of one tank of gas is not an average at all, but rather an aberration.

[Pandemic]

I got 38mpg once. Filled, drove, put more fuel in and figured it to be 38mpg. Still trying to figure out how I got that. I got 480miles on a tank before. That's the highest accumulation on a tank.

[5spd'r]

I'm testing a blend of 3oz acetone, 1.5oz xylene, and 1.5oz 2stroke oil (shaken, not stirred) added to a full tank. I don't expect much until the gas goes back to non-ethanol, it does seem to run better already though.

This mixture in a tank of 87 Conoco yielded 26.8mpg, all city. My previous tank had nothing added, I drove more carefully and got 23.2. My wifes 2000 EX 5spd with the same additive dropped in mpg to 20.5 Must have something to do with the OBDII set-up...doesn't really matter since CB7's are all OBDI anyway, maybe someone at TOV would know.
