Because I'm getting poor gas mileage, I would like to know what I am supposed to get if my FB was healthy. So what how much mpg do you all get with healthy FB's?

 

this was just explained in my thread man.

 

stock in good condition 20mpg in the city, 26 mpg on the open road, but 16mpg if you have a heavy foot.

 

wow, im running pretty shitty then. i counted 12 mpg city on mine. i think i need lighter shoes.

 

I saw 22 on freeway... once. Otherwise it's 12-16. I need a rev-limiter at 4k

 

SE's will get slightly worse fuel mileage than 12a cars, but I usually see about 16-17 city, and about 19-22 highway, depending on local terrain.

Best mileage is gained when you have high tire pressures, good alignment, high density tires (600+ treadwear rating), no aerodynamic accessories, no headlight use (daytime), no A/C use, no excess electrical load (radio, amps), cruise control ON, and just yourself.

Other things to consider are the condition of your wheel bearings, engine oil weight, trans and diff oil weight and age, and whether your brakes are dragging at all.

All of these things can contribute to GOOD mileage, so you may want to check some of these things if you think you're getting POOR mileage. Good luck,

 

I get about 20... better when i make the 80 mile drive to lexington... all highway

 

I drive my 12a everyday...80 mile round trip...in the open desert of Az. Cross a mountain pass coming and going, and enjoy those curves combined with ***-dragging slow-pokes. 23 mpg...consistant or the way look at it, 360 miles on the OD equals 25 bucks.

 

11 mpg

 

24 mpg, mostly highway driving at 80 mph, stock 85 GSL.

PROPER Tire pressure is what I assume you were meaning

Too high of tire pressure causes uneven wear and premature tire failure... Also makes the tire more vulnerable to damage from cuts, and punctures...

Never exceed the maximum cold pressure rating stamped on the sidewall of the tire....

 

But what your going to find is the proper tire pressure rating for the car, is not allways the high tire pressure on the tire. the rating is on the door cutout, close to the door latch.

If you have stock suspension, you fill the tires to the cars requirnments, not the max the tire can hold.

 

You guys are certainly right, you shouldn't exceed the manufacturers rating for cold pressures on the tires, but tire pressure is one of the MAIN determining factors in fuel mileage.

Case in point is the Toyota Prius, which gets about 60mph (yes, sixty!), and comes standard with high pressure, high mileage tires which are manufacturer rated to 65psi - DO NOT attempt to inflate your tires to this pressure! This is also considering that the car weights 2250lbs, has 14x5" wheels, and a hybrid electric/gasoline engine.

In other words, Toyota decided to go with extremely high pressure tires to help reduce rolling resistance to sustain high mpg ratings. Something to think about...

 

i usually get about 20-22 highway and like between 16-18 mpg in the city with my 80 LS. it has 58K, all original.

 

I get about 12 in my automatic 3-speed. This is about 50/50 highway street.
