Just curious here, what kind of gas mileage is everyone getting? And how big of an engine do you have?

 

5.2 and dont even want to know

 

5.9. 9-10 in town, 11-13 highway. Bleh.

 

5.9L 4x4 14 city, and 17-18 highway.........do your plenum...that will give you better mpgs....before i did plenum, i got 8-9mpgs, after i replaced (along with other engine parts) i got the 14mpgs

 

I did it < a year ago, made no difference. No oil in the intake as of last Saturday. Oh well, it's summer so I can roll on two wheels most days.

 

i didnt just replace the plenum....i had the hughes kit...manifold cleaned at a machine shop, and it looked brand new inside and out, did the kegger mod, coil, plugs, wires, dist. cap, and rotor all at the same time...

 

There's already a gas mileage thread in this forum, and with that I'll tell you that I'm getting 25mpg.

 

After joining the forum I now run nothing but SeaFoam so my gas mileage is infinite.

 

Yep, fill the tank once with seafoam and you're good for the life of the vehicle

 

Hey VW, how's that HHO generator been working for you?
