Hello all, first post here. As the title says I've gone over 5000 miles on my oil. I drive an '08 cobalt coupe LT. I had read about dexos1 oil and had GM dealership to put it in my engine.
At Oil life percentage it's at 62%. The Oil looks light brown on the dipstick. I've been thinking that's a lot of miles and wanted to change it and probably will, but is it really needed. I did a little digging and I believe ACdelco synthetic blend is what kind of oil it is..
So what kind of oil do you all use and how often do you change it.
That's a lot of miles. I've never been able to go over 3000..She just rolled over 100000 miles on this oil too. I'm about the 3rd owner I think. Planning on exhaust upgrade and injen CAI in a few days so I really would rather have fresh oil.
Meter in Cobalt is calibrated for full synthetic. So change dyno oil at 50%, blend at 25%. What is real important with the ecotec is to keep oil topped off so timing chain runs well lubricated and cool from a constant shower of oil.
Every minute spent angry is a happy minute lost for ever and ever!!!

I have been using Mobil 1 EP since 30,000 miles 2005 LS at 123,000 now. I change the filter when the indicator is at 50% and the oil at 5% which is usually 8-8,500 miles. I do check and top it off as needed.
i used to run 3k and change the oil when i was running normal oil, now that i use valvoline max life full synthetic i go to about 5,000-6,500 before i change the oil. you have to constantly check fluid too, in the past i went 3k before changing oil and it was 1.5 quarts low when i changed the fluid so i have started keeping a quart handy. idk where it all goes cause i dont have any areas that look that bad and i dont get spots in the driveway.
