Good luck. Write back if you have any other questions.
I am rapidly giving up hope on this vehicle ever getting close to the mileage that the '93 did. Anybody got a suggestion of what would be a good, reliable, fuel efficient replacement vehicle?
I was just wondering what year model vehicle you have, and, was there an error light, or something, that made you suspect the oxygen sensor was faulty? I want to believe that my '05 Safari van can get better economy than it is getting but I have not been able to find any solution as yet.
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.
I`ve talked with people who are getting 17-21mpg.I had shepard chevy in lake bluff send me homewith a bad Idler arm.I just drove 45miles one wayafter my mechanic showed me the arm was bad.I was hearing clunks under r.f.I took the afternoon off and took it to shepard where i bought the van.They pumped it full of grease so the noise would go away,and sent me home.Here another oil chnge later I`m at bill kay chevy downers grove getting it fixed and it tsill is making noises.Chevy sucks.Shepard Chevy.Con artist.
My previous ''95 RWD van got around 21 mpgs. My used 2001 AWD Safari is around 15 mpgs. Yes, A pig - even when going down hill and with the wind. 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.
5 speed auto tranny i have a little over 100k
25 MPG HIGHWAY @ 70 mph going to Miami
this van is fast sometimes i race people on the streets if i do that i only get about 10 miles to the gallon
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" :mad: )
I get 20 in town with my 2 wd but the AWD we had got 14.
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? curse high gas prices!!!
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....
P.S~ Would it help out any if I got it in for an alignment? It's off....not real badly, but enough to tell......
- Closer to the ground means less wind drag. If you have a raised van, do lower it back down to factory ground clearance.
- New shocks on all 4 tires (like Blistien or Rachos HD shocks) to reduce too much up/down movement help a little as well. Especially if pulling a trailer.
- Smaller / lighter tires means less rubber weight to "get going". Especially if the axle gearing of your van already has "lugging" behavior. Lugging because its gearing is too high - for your road / hill conditions.
- Pull away "slowly" from the stop lights / stop signs. Let others "wind vacum" your vehicle forward. LOL!.
- Being slow on those hiway access ramps (like the big loop clover leafs). Today, I no longer bank my van on 2 wheels. Especially on those tighter clover leafs.
- Less internal weight (like removing unneeded row of passender seats - until needed). My buddy removed his middle row of seats for his dogs. When he does passenger trips, he & his son re-installs his middle seat. Works for him.
- Using cruise control and set to -3 mph slower then posted speed limit. Same speed as most transport trucks - in my local area.
- Only use AC when needed. re: The high climate justifies the gas consumption of AC. No more running AC because one can.
- Wheel aligment / wheel balance.
- Ensure vehicle has good spark plugs, clean air filter, its thottle body is clean, its injectors are clean, its timing is properly set, etc. etc. Mechanical tune ups do save gas dollars in the long run...
- Proper tire pressue (as stated on the tire and not in your manual) helps as well. Note: Tire pressure is based on towing and non-towing loads. One lbs rating doesn't fit all brands of tires. Therefore, be prepared to adjust some tires - based on their usage.
As they say, every little bit helps.
I was traveling to Alabama and I have the transmission making a shift very rare I have stop at the moment check the Trans oil and I tough it was ok, but next mile it did the same so I stop at walmart and I have added some oil.Service Engine came on and MPG started to go from 19 to 18 and so on until 14.8.
When I came back home I took it to Advance auto partsand they get the P1870 code " Transmission Slip" they have recomended Lucas product Stop Slip also an oil change.
Should I change Transmission Filter and O ring? and add Lucas product?
What else other than engine oil change, air filter, fuel injector cleaning can help to improve MPG?
I'll appreciate any one can help me, I have this van from original owner and never gave me a problem.
Spark Plug wires
I have make an oil change and replace oil filter
I have flush the transmission oil and replaced.
I added a fuel injector cleaner.
Guess what, I have increased to 25 MPG when I travel from GA to VA.
But After almost 1.5 years after and continusly changing engine oil and filter I have a transmission problem that I have posted recently and I have bad MPG.
I'm just hoping that some body can help me too.
I hope you get that van fixed soon! I've given up hope on my astro and will be trying to sell it soon....I loved that van, it was SO much roomier than your standard minivan and it hauled alot of things, but I've lost the battle with gas prices and can't take it anymore, I'm sad to admit, I'll be looking for a small sedan soon.....curses!
Is it worthed?
Thanks for your reply.
If my GMC Safari van "blew up" tomorrow, I'd probably get a 2007 "demo" Uplander Van. This year has the bigger front brakes, larger size engine and a few other design improvements the other previous GM van models don't have. Demo is around $18K - compared to the $30K of a 2008 models. If I neeed to haul stuff, I'd connect my larger size engine "smaller" mini-van to my 6x10 or 4x6 utility trailer. And when not needed, I'd simply back the trailer into the bush and pull its pin (sort of speaking). Thus, no need for a larger size mini-van (that's a pig on gas).
Hope this helps - some how.
and will see if I decide to sell or fix this vehicle.
Have a nice day.
I do not trust in any repair shop near by plus I velieve is not worth for me to spend as you said $2000 usd.
I'll rather get some money and use it to get a newer car.
Just wondering if you knew about flushing the transfer case? My 99 Safari was hard shifting after a 2 hr highway drive, and we got the transfer case flushed and it fixed it. There is some known issue with it that came out in a GMC bulletin. Most people assume it's the transmission, but it's not.
Where is the transfer case located? is that the rear axle thing?
before I made that trip, I took the van to get the seals and bearings replaced on the rear axle, they actually remove and replace the oil.
I actually found on you tube a very nice videos on how to give maintenance to that Transmission.
I'm really going to do it.
I divided the number of gallons put in into the number of miles I travelled. I triple-checked my math. I didn't believe it either, but there it was. I was hauling, maybe 800 pounds in the back.
my rps are very low on the freeway , i also have new oxygen sensor and the van :shades: is been lower 1 inch
