So someone was telling me they get 20-25 mpg in there cherokee

Well yeah if you want to drop a **** ton of money on alcohol injection you'll get better gas mileage. Not worth it in my opinion

DFlintstone

Mine would regularly clear over 20 MPG, years, and 150,000 miles ago. I recently posted getting nearly 25 on a highway trip, but It was most likely a mistake. Did get close to 20 on the highway on my old 703's. (746's in there now are untested on the highway)

If it's a HO 4.0/auto and they're claiming 25MPG, the alcohol isn't being consumed by the engine.

Maybe with injection. I'm getting around 18 around town. And I get 25 or 26 on every highway trip I take. I have alot of engine mods though. And it's standard

Sorry guys I got cut off in the drive through . They told me to put 91% rubbig alchohol in my gas tank . Is this complete bull ? Lol

Radi

That's 9% water. Yuck.

Radi

Yeah, the manuals are better. AW4 is not a particularly efficient transmission.
What sort of engine mods did you do to increase mileage?

Bustedback

Complete bovine excrement, don't do it.

Cowl intake mod, neon injectors, all new fuel system components and all new electrical. Guess it helps I'm only runnin 31s with the rubicon wheels, (steelys are heavy I think?) and I think the jeep might have been regeared. And I do stuff like try to coast more and what not to save gas. And it's pretty flat where I live in Texas to lol

EvstaG

Lol. Even if it ran, it would be lacking power pretty severely. The energy density of isopropyl alcohol is a fair bit less than gasoline's.

wanna-be-a-wheeler

They said fill up like 14 gallons ( I only have a 16 ) and put the alchohol in it . It burns hotter or something . So bull on this one ?

If you run straight ethyl alcohol with your gas it'll up the octane level.. but its not necessarily all that good for your engine. Shiners used to run it in their cars back in the day for a little boost.

EvstaG

Definitely. We already know what 10% ethanol does to your economy/power.

Curious as to how this is different than E10 or E85 nowadays?...
