Hello, I just bought a 2003 gmc safari and i like the van but the gas mileage is really bad.I am looking for any mods to help increase the mileage? First tank i got 17.5 mpg (thats imp. as i live in canada,) thats about 14.5 mpg in us terms. So far i have put in a k&n filter cleaned the mas sensor and infalted the tires to 35 psi i drive easy about 90 kph on cruise so i will see what milage i get out of this tank.I also removed the roof rack.if anybody is running a chip let me know how this has affected your milage.

When our "run about" FWD (other) vehicle is paid off in 2 years, our 2001 AWD Safari van is gone. To be replaced with a 2WD vehicle - like Envoy XL or simular shape machine. . Gas savings alone will pay for a much better Tow / family touring vehicle. If you can't get better mpgs, time to replace with something better. .

Replying to: jrbudge (Jun 20, 2007 11:36 pm) My '94 Astrovan ( I'm saying all this as I fight back tears) get's like 4mpg period, I swear! Ok, really, it's probably like 12, but I don't know how to fix the problem! Someone help me!! Either the mpg's improve ASAP, or she's goin' up for sale (or "Free to good home"

Thanks for the post, I appreciate it. I was REALLY hoping to take this van on our road trip this coming Labor Day weekend (total time is a whole hour and a half to get there) because out of both vehicles (our other is a '92 blazer) the van has air. I highly doubt I'll be able to get a round trip out of the van on a full tank though ( if map quest is right, round trip=148miles-ish). Unless my calc's are off (I was never good at math, I shamefully admit).......? Maybe I should just accept the idea of a friend of mine's. He said that back when our van was built (again, it's a '94) it wasn't built with gas mileage in mind. Does anyone else think that's true?

Replying to: antique_maggie (Jul 07, 2008 10:25 am) If time or faster ground speed is more urgent to you, perhaps it might we less expensive to "rent" a smaller mini-van, mini-station wagon or rent the car of your dreams - for your long term trips. The "gasoline cost savings" by using a more fuel efficient rental could pay for the daily vehilce rental fees. And, you get to try a different vehicle for long distance travel. Great research opportinity for your future van replacement - when that special time comes. If wondering, my FIL (Father In Law) does that. He keeps his GAS HOG V8 4x4 GMC pickup for local driving and rents a fuel efficient vehicle for his long trips. Works for him.... Hope this idea helps as well.... .
