there have been a ton of topics on this, do a search..The consensus is German Castrol 0W-30 is the best..It's at certain Autozone's only

Now, for those of us in the northern tier states, in the dead of winter, there are not many better oils we can possibly use.

I use Mobil 1 5w-30 and a K&N oil filter. Have used that since i bought the car back in 2004, and 30K miles later.

i really dont see a down side to using it. its all a 30 weight once the oil heats up some.

Somewhat true, but there are sometimes BIG variances in 2 different oils labeled a '30 weight'. The API/SAE give a range of specs (cSt @ 40 & 100 degrees centigrade) for each and every labeled weight. Some oils come in on the heavier end, some on the lower, some right in the middle.
This is one of the reasons our engines 'like' (and so many on here swear by) the German Castrol, even though it is labeled a 0W-30 as well. It's '30 weight' is actually closer to a low 40 weight rating (in cSts). :wink:
