Am I wrong or doesn't the season and temperature have something to do with the viscosity you choose?
Hey Zapata, how many miles do you have on your car? I was going to change over at 12K miles.

Yes, in simple terms
colder the temps, lighter the oil. Also lighter oil creates less
friction on the engine, hence the 5w30 in our cars. Its all about
fuel economy.
check your manual, it has the ranges listed in a chart.

Because it's not fully synthetic. There was a dicussion on this board a while back. Mobil had to come out in and say it contained "regular" oil and their synthentic was actually a blend. Sorry, i' can't provide any more detail but I was at work till 2am last night and i can't think straight

Get some rest man! I hope they paid you for that mad overtime.
Yeah, I'm gonna find that info out b/c if that's the case then the
bottle has false advertising. "Fully Synthetic Motor Oil"

Amsoil would be my alternate as well, worked well the RX's
and I assume its quality will prevail in the CLS.
