gas my 2006 chevy cobalt ls drinks alot of gas will it hurt to put gas treatment in it or a higher octane of gas
Neither will hurt. But neither is likely to solve the problem. If you have over 100,000 miles on your Cobalt you're due for a tune up. Check the air filter and replace, if needed. If your check engine light is on have the issues causing it to be on fixed. If you have a tachometer take the car down the expressway at about 60 MPH your tachometer should be between about 1000 and 1500 RPMs. If it's running higher in drive something's going on with the transmission. Most likely the torque converter clutch isn't locking in. These things will all effect gas mileage. HTH. -Jim
thk u so much for ur help u have a blessed day
In addition to what Jim suggested, check the air pressure in the tires. Under inflated tires are a big killer of fuel mileage. Also I always recommend Techron fuel additive. It is available at O'Reillys, Autozone and similar places.
You're welcome. Glad to help. You as well. - Jim
