Replying to: ateixeira (Dec 02, 2008 10:37 am) I second the idea of taking excess weight out of the vehicle.   Seriously You drive a 5000+ pound SUV and you're concerned about the weight of a bag full of plastic toys?   Then again maybe not eating happy meals will keep a couple of hundred pounds off the family average over the long term   Backing off about 5mph would probably yield 10x more in gains.

#1055 of 1070 Any effect of empty roof rack on mileage? by lmacmil Dec 12, 2008 (10:51 am)
Edmunds did a test last winter on the mileage effect of an empty vs loaded roof rack. Mileage was about 20% less with a couple of items on the roof rack. I'm wondering if there is a significant effect, say > 1 mpg, of an empty roof rack vs no roof rack at all or if the cross bars have an effect. Fyi, I have a Highlander that came with a roof rack that I have never used.   My guess is that an empty roof rack has little effect on mileage. Anyone seen any data that says otherwise or care to speculate? Replies to this message: ateixeira (Dec 12, 2008 12:03 pm)

#1057 of 1070 MPG SOLUTION!!! by xtierra Dec 14, 2008 (12:09 am)
Replying to: wayn1 (Jan 01, 2001 11:06 am) my 2005 xterra 4X2 would give me close to 400 miles per tank on highway trips.... my fuel gauge went bad and i took 4 months to fix it. once i fixed it along with cleaning my battery posts, i was shocked to see my truck use too much gas.... i was around 11mpg!!!!!! so with 100,000 miles i thought it is something with my engine... cleaned throtle intake, mass air sensor, new spark plugs,new tranny fluid, new diff fluid..... 4 bottles of lucas fuel treatment..... got up to 13.89mpg.... mechanic plugged nissan computer and showed me that my engine was performing at 86%.............. wow........... he re-set the ecu and instructed me to keep rpm's from 1000 to 1500 and drive to and open highway to get to 60 mph with low rmp's and to keep at 60 mph for 15 minutes..... while the ecu completed the re-learing procedure for the air/fuel mixture..... took a 265 mile trip the following weekend through mountain areas at 70 to 80 mph and got 20.25 mpg////////////// BACK TO NORMAL..   if you notice your mpg dropp, did you have your truck at the dealership? did you disconect the battery? this is the most common cause for bad mpg.

Replying to: xtierra (Dec 14, 2008 12:09 am) 1000 to 1500 rpm? Wow. That truck must be geared super-tall.   Just make sure you don't lug the engine.

Replying to: twoplankr22 (May 21, 2009 10:47 am) During warm-up you get poor mileage, so maybe the fact that you've been busy means you're driving it longer and more often when the engine is already warm. That helps.   Avoid short trips, and try to combine errands so the engine is already warm when you start.
