I've used Mobil1 since the first oil change, 16K miles so far and no problems.

Well it looks like its between Moblie 1 and Royal Purple. I asked the guys at my local shop and they swear by Royal Purple..... but of course the stock it and not Mobile 1 . I dont know. I live in Las Vegas and it get hotter than Hell here so thats why im so into what kind of oil I get. Ill probably go with Royal Purple because people tell me its the bet for high temps. Who really knows
Let me know if you have any proof that one is bette than the other.

Mobil 1 Full Synth. I like Royal Purple as well but its too pricey for me. I will use Royal Purple in all the other spots in the JK when it comes time.

You can't go wrong with either one. I used Mobil 1 because of the price. But I use RP in the drives on my boat and pay $10 qt. (only change once a season).
