are there any tiiiiny injectors you could get to up mpgs to about 23+??

Alsoo, can you run Straight (coffee filter strained) used motor oil thru the gas and have it work? or is it like 1 gal MAX

You would lose a lot of power. And by that time it would use more fuel getting your truck up to speed. If you want to try it out just back out the fuel screw. It would be like doing the same thing.

would i make 20+? and no problems even on the .018 injectors?

I`m no expert but... seeing as how a diesel is throttled by fuel quantity not air (like a gasser) injector sizing has alot less of an impact on mpg`s. You could have showerheads installed and as long as you don`t call for the HP the pump won`t supply it. It`s the reason diesels get such good milage as it is, the ability to run a 100to1 A/F ratio. As far as the WMO, I think you might have to be your own R&D lab to figure it out, personally if I was going to put WMO in my truck I would filter it alot finer than a coffee filter.

There's a "Cummins approved" amount of WMO that you can use. Personally I don't want to do. My truck stinks enough as it is!

If milage is that big of an issue then buy a GEO.

You sure this is a good first vehicle for a 15 year old? A 500hp twin turbo'd 1st gen?

Your right foot is the best fuel saving device.

ROLCOAL

Lol, cowboy in a geo.. Nah

Yes.

I know, i was trying not to smoke it. And, that meant driving REALLLY lightly, so mpg+++

I doubt you could even get close to 20mpg. The best I could do with 6x16's was like 17mpg.

C/PRD/

HAHAHA I guess you've never rodeo'd. At least not from my side of the arena. We packem deep and travel cheap. I never was too proud to throw my riggin in the back of a GEO.

Auto or stick?

I get 20MPG with POD's and the fuel screw all the way in, but I have to drive it carefully and coast down long hills.

ROLCOAL

Lol, not out here in the bay!

Auto... Darn fuel. Whys it gotta be so high??? (pretending to be ignorant, not bringing Europe up)

My last tank was 17.4, that's mostly highway at 70+ mph. If you drove 55 all the time you could probably squeak 20 mpg out of it but it wouldn't be any fun at all.

If you want to detune the truck, don't buy it. With twins it will not be a good driver with small injectors. Buy a truck that's closer to stock if you want high mpg. A D250 is the best way to go if you want fuel economy.

hmm, decisions decisions decisions

ill see how this job pays out. and then ill go from there.
