    Oil change interval?

    I've a 2010 LT Cobalt and live in Portland, OR area. I had to change the oil every 3000 3x in a row to eliminate sludge...it worked. If I recall my dealer said to switch to 5000 mi intervals after I completed the 3 3000's. Does 5000 sound adequate? If I stretched the 1st one to 6000 would...

    Auto headlights

    I love my auto headlights on my 2010 LT cobalt, but I'm wondering 2 things: 1) Will they drain car battery quicker? 2) Will they cause the bulb to wear out quicker? Thank you. :High 5:

    I have a 2010 Chevy Cobalt LT, 2.2 liter. My husband says he can change the coolant, the spark plugs, and the fuel filter. He's done those on our other cars in the past. He doesn't want to watch the instructional videos/look at instruction posts online....since he says he knows all that...

    Can I change fuel filter on my cobalt--easily?

    Dealer wants $96 to replace fuel filter. It's in front of the fuel tank so that doesn't need to be dropped. Auto zone has a Duralast one for $22. Should I do it myself or is it too technical or is the dealer filter better? :juggle:

    Where is fuel filter on 2010 LT?

    Dealer wants $96 to replace fuel filter, says he'll have to drop the gas tank to get to it. Meinecke repair shop looked up my vehicle and said the filter is in front of it so no need to drop tank. Who's right?

    Service maintenance: Should I listen to oil change shop or dealer?

    I recently had an oil change at Oil Can Henry's. They printed a service maintenance schedule for my 2010 Chevy cobalt lt. They said I should get my transmission fluid changed.
