In May, 2008, soon it was getting around 30 miles to the gallon. Since the summer, it's dropped to 24 -25 mpg. Service dept. says it's a problem with Ethanol in gasoline. Is there any indication that other hybrid Vues are getting less than the promised mileage? Our dealer won't call Detroit to find out. If it is the ethanol then I know we're out of luck. If not, then what could have happened to lower the mileage 16 - 20%
Thanks for any help.

Re: Poor gas mileage in a 2008 Saturn Hybrid Vue
You are always going to get worse gas mileage with E85 than regualr gasoline. My sister has a colbalt and she mixes 1/2 gas and 1/2 e85. The dealer told her she could do this to improve mileage. I would not try it in your car unless you check with the dealer first, it could mess your engine up if you do it. If you are getting that mileage with gasoline, then i would change spark plugs to bosch platnium 2 or something that allows more spark.

You can change the spark plugs and coils, wires for a little better gas mileage. I would say 60,000-70,000 miles. If you are under that, probably still ok. You can try fuel injector cleaner in the tank. Check your tires and make sure they are properly filled up. If the vehicle is out of alignment, it will cause bad gas mileage. Make sure you have no vacuum leaks and make sure your air filter is clear. If you have any questions, just let me know.
Make sure the air filter is clean. Have a diagnostic scan done to the engine to see if there are any trouble codes or issues that would reduce your gas mileage. You are getting around 11 or 12 miles to the gallon, which isn't very good. But, judging by the low amount of miles on the car, you apparently do all your driving in traffic, and short distances with a lot of stop and go. If you let the engine warm up for long periods of time, especially in cold weather, that will drop your mileage considerably. Letting a car warm up for 10 or 15 minutes in the winter gets you 0 miles per gallon for that amount of time. Add all these factors up, and figure in the poor quality of today's fuel, 12 miles per gallon is not too far off from what you should be getting. If you have the v6 engine, your mileage was probably around 15mpg when the car was new. Now if you were to take your car on a road trip where you could drive a long distance with the cruise control set on 65mph, you would probably get around 18mpg.
Do you normally accelerate quickly from stopped? You can increase your cars mileage by cutting down on rapid starts and stops. A comparable Honda Accord Hybrid rated at a higher 25city 37 hwy MPG rating achieves less than 22mpg when driven HARD
change your spark plugs if they haven't been changed in awhile. check your tires for the propper psi there should be a sticker on the inside of your drivers door that will tell you recomended air pressures go by this not the recomendations on the tires. also where are you getting you gas does it contain ethanol sometimes this can burn faster.
I was just listening to Car Talk on NPR (Click & Clack) talking about this exact thing in response to a callers complaint about poor mileage. Their advise was to: a. check the compression and b. check the thermostat. With your 2001 being 7 years old your mileage is probably under 100,000 so your compression is probably OK. If you do check it the good compression should be about 150 PSI; if it's down around 100 PSI that could account for the poor mileage. As for the thermostat if your engine temperature doesn't get un into the normal range fairly soon, the computer thinks the engine is cold and adjusts the choke accordingly which uses more gas
Our family has owned Saturns since 1992. They've always been reliable out-performers, until the most recent one. I took delivery of my 2007 Hybrid Vue on 31 May, 2007. From the first tankful of gas, the mileage has been woefully short of the projections - worst case was 19 and best was 32 on the freeway at 70 mph and no air conditioning. Most recently, I drove the Vue down I-95 in Florida at around 70 and no A/C. Mileage? 28. Do the math. That's about 3 mpg better than my first Vue would have gotten. At $3 a gallon, it'll take me approximately 233,000 miles to recoup the $3000 premium I paid for the car. If you live in a climate where air conditioning is not a means of survival in the summer, then this car might be OK.
