Are you a current or recent car shopper who bought an EV and then installed solar – or who had solar already, making the decision to go electric easier?
Are you a recent EV buyer (past 3 months) as a result of manufacturer incentives and dealer discounts on these vehicles, including year-end deals? Were you convinced to buy an EV after finding a good end-of-year deal, or due to uncertainty around which EVs will no longer qualify for full/partial EV tax credits in 2024?

    With my 1995 4door Sunfire, I average 30 mpg with combined city/highway driving. Not too bad. The car itself has held up great and drives well for being over 10 years old.

    I get about 13 MPG on the highway with my 01 Sunfire. it has a 3.8L v6 with 2 turbo chargers running about 35 lbs of boost. but i am also caring a lot of weight the spare tire well is loaded down with concrete and on top of that i have a 6 sq/ft box with an orion H2 thats about 600 lbs including the concrete. i have 3 power bass amps that weigh about 150 combined and 18 inch limited rims. a lot of weight + a lot of power = no MPG

    I have a 2001 Sunfire SE 2.2 and wondered if anyone out there experiences poor gas mileage and an erratic gas gauge? I did a recent tuneup( plugs,plug wires, air filter) and I only get 18-20 miles per gallon. Its really seems to burn the gas. No matter if Im idling,in the city, or on the freeway, it chews it up. I have 125k miles on it and it seems to run pretty decent. Anyone have any light to shed on this?
    Thanks :confuse:

    I live about 10 miles from work, mostly highway. Still get about 29-30 MPG with the 2.4L engine and a manual transmission. Still love my car.

    Hey slackerman:
    Any ideas as to what may be why im getting horrible gas mileage,even after doing this tuneup?

    I have the EXACT same problem as moe75 ( also recently did a tune up, mileage is 128k miles) - anyone know what may be causing this poor gas mileage? Thanks.

    All of a sudden my temp gauge (2005 sunfire) 2dr would not go back to zero when engine is off - - so when engine is os on, the needle was in overheat range. It continued to move higher and now reaches all the way over to Tach and keeps tach needle locked. It stays with way whether engine on or off. Any suggestions? Do I need a new instrument cluster?
    Also if I get a used gauge cluster, is the cars milage picked up from PCM and transferred to the newly installed cluster? Thanks

    Can anyone post they're milage there getting per tank? I'm in Ontario Canada and I'm getting not to bad hwy milage but in the city I'm getting maybe 400 km (248 miles) a tank. When I first got this car, I could get at least 450 a tank but now I watch the needle get within a quarter of a inch before it comes near 400.

    My brother had the same problem with his 96 firebird formula. Try a new sending unit or ask your repair shop if a sending unit would fix it.

    im driving a 2003 sunfire with 100,000 and im still getting 375-410 miles on a tank.
    that is combined city and hwy use. but i refuse to run my a/c and use the sunroof and windows to keep the car cool. I f i use the a/c unit it drops my mileage to 250-300 miles per tank.
