Re: gas milage

you have an underpowered engine on a heavy vehicle. that is the reaso nwhy the V8 gets about the same milage. you can trying doing simple stuff such as changing the plug and such but i doubt you increase a whole lot.

Re: gas milage

big car little engine does sum it up.

However, my 2007 averages about 18 city and 20 highway. Sounds like you're due for a good tune up.

Plugs, wires, seafoam, check tire pressure.

Re: gas milage

My wife's 3.7 consistently gets 17-18 city, 21-25 highway...but it's almost painful driving with her. Total granny driver. Plus I maintain it, so it's no wonder it gets such good economy..hahaha This is a totally stock 06 3.7 with nothing more than an K&N drop-in.

Yeah I don't mind an average of mid to high teens I just figured something had to be up for it to be that low I don't want to say I'm more of a granny driver but I'm no Jeff Gordon that's for sure since I've had the truck for about a week I'm not as familiar with it as you guys can someone fill me in with correct plug gap and plug info and all that other fun stuff

Not to sound like a complete noob but what is seafoam

Re: gas milage

I'm pretty sure the gapping is listed under the hood on a label...but if not, all that info and MUCH more can be found on wkjeeps.com. It'll become one of your favorite sites.

Seafoam is a chemical you can dump in your tank, crankcase, and via vacuum line that cleans out your entire fuel system and engine basically removing any carbon and funk build up and expelling them via the tailpipe in a rather impressive cloud of white smoke. If you google video or youtube it, you'll find all kinds of vids of people doing this.

Re: gas milage

I'd say there should be some inprovement somewhere. I average over 19 if I drive all highway at 70. City driving is lower but I would think you should still get 17.

Red face Re: gas milage

Welcome to the garage Matty. We seem to share the same taste in cars. I still have my 2000 Altima but will probably sell it before winter comes. It still gets some city driving chores. On my WK, over 40,000 km my overall consumption is 11.8 liters/100 km. Not sure if my quick math is correct, but that's between 20-21 mpg US. I don't drive with a heavy foot (steady acceleration is the key, keep it at the speed limit...even a little over in the city) but neither am I a hazard on the road!

i still have my altima too (used mostly to bring the jetski to and from the dock and a little bit around town)

im going to get some seafoam and plugs and a new air filter and try that out today ... ive only had the truck about a week and according to the dealer these were done recently but then again who trusts a used car dealer ??

Re: gas milage

The more ethanol blended with your fuel the worse your MPG will be. For example here we have 10% ethanol and my MPG suffers by 10-12% over what I use to get with the good stuff. The more ethanol blended with your fuel the less MPG you will get. Thank you Politicians.
