Have used Mobile 1 0W-30 since new. Last week I tried the new Penzoil Ultimate Synthetic 5W-30. I will be going back to the Mobile 1 long before the recommended oil change interval. I am going to put 500 miles on this Penzoil then look at sending off a sample for analysis. I'm not impressed with it. After going back to the Mobile 1 I plan to do the same just to find out if I'm hearing things.

Motorcraft 5w-20 with Mopar filter. Worked in the F-150. Good enough for the JK. If Mopar sold oil at Wallyworld, I would run it.

5w30 for the winter
10w30 during the summer
Always synthetic

Brand name isn't so much a concern, so I use whatever I come across that costs less
