optimal MPG mods

It definately doesn't lol

This is all true. And a low thermostat will not allow the engine to get to proper temp [also if the computer is still hooked up, it won't stay in closed loop] and will cause it to run richer, using more fuel.

I %99 agree, however, 1993 has only manifold o2 sensors... so the obd1 computer has no knowledge of the catt. anyhow... I still believe this is an improvement. That and the plastic fan. Less weight to spin than stock metal

Tires are still the stock 265/75-16 but they stick out farther than stock with the offset wheels. Add mud flaps, and lift... yeah, its about as aerodynamic as a mattress....

i might be removing the mud flaps. Theyre too small anyway. I only added them for salt protection. Not a problem in CA...

just learned this driving around with your lights on robs you almost as much MPG as your AC compressor... which I have been doing.... I heard having lights on youre less likely to get hit by morons cause your eyes are naturally drawn to light. So I guess there's a price to that caution. ...

If you are worrying about the wind resistance of mud flaps and a t bar crank every other aspect of you truck must be absolutely perfect haha

Lmao alright

The science behind it is true, but on our pigs, I've never seen it make difference.

It is physics man, you can't LMAO physics.

Why do you think a dropped truck gets better MPG than a lifted one on the same tire sizes?

If I were to extent the front valance as far down as I could it would make a difference that you would see when you calculate after each fill up.

Yes actually I can if you think a 2 inch piece of plastic hanging off the front of a 20 year old truck has any measurable effect on How many mpg it gets I'm surprised you can even spell physics. Yes a lowered truck gets better mpg than a lifted truck that has no relevance what so ever in this conversation. If your argument is that air that hits a blunt valence is somhow less turbulent under the truck ok maybe a minimal amount, but to argue that air turbulence under one of these trucks makes any difference in mpg is laughable. Bottom line GM put them on for looks to hide the suspension parts better. With that I'm out I'm not supposed to be arguing on here

Obviously it is measureable. It does have relevance as he said he took the air dam off. If all you change is the height of the truck then yes a lowered truck does get better MPG, for one because it is less of a imprint rolling down the road and the fact that there is less air going under the truck.

You are always arguing on here and always stiring up trouble then peace out like you are the bigger poster. I don't care how many GMT400 trucks you have owned, how many posts you have on this site, or rep points.

I post a valid point that involves science and you start with the kicking. Go read a book and watch some windtunnel videos.

The less air that flows under the truck the better, that air gets turbulent thus causing resistance.

When you are talking such low MPG, every little bit does count. What doesn't count is you LMAO posts.

Haha ok have a good day big guy

I am not understanding how air hitting a vertical piece of plastic is going to increase MPG. By his reasoning, if i extended my valence all the way to the ground, it would get better mileage.

Yah I think I'll just bolt a piece of plywood to the front of my trucks
