I have a 2002 Chevy Impala LS with the 3.8L V6 and I have 40,000 miles on the car now. I've been using AMSOIL Series 2000 0W-30 since the car had 3,500 miles on it. I'm wondering if the Series 2000 0W-30 is the best oil for my car... Should I maybe go with the Synthetic 5W-30 (ASL) or the Synthetic SAE 10W-30? My car calls for 10W-30 on the oil cap. When I first emailed AMSOIL about it a couple years ago, they told me the Series 2000 0W-30 would be the best. I usually change my oil every 8,000-9,000 miles. I use the AMSOIL SDF-29 filters, and I change it at every oil change. I ask because I've read on here that some people don't like the Series 2000 0W-30. Also, the S2K 0W-30 costs a good bit more than the other synthetics. For the most part, I'm looking for the BEST oil for my car. Secondly, I wouldn't mind saving $3-4 a quart if one of the other two are better.
I live in Baton Rouge, LA (hot summers, mild winters). I've put a 180 degree thermostat in my car (down from the stock 195 degree). I've done a few performance upgrades, such as a cone K&N style filter, reprogrammed PCM (premium fuel required), and high ratio rocker arms. Thank you for your help!
