They probably run 5W-20 because i think its thinner leading to a little bit better fuel economy which we all know we lack. __________________ --------------------------------------------------- 2008 KK Liberty Inferno Red Daystar 2" Spacer Lift With SkyJacker Rear Hydro Shocks 245/75/16 TreadWright ATB Front Pass and Driver Mopar Tow Hooks Mopar Rear Tow Hooks Mopar Skids |

151 Wild Child Racing | most vehicles these days are leaning towards 5W-20 for the fuel economy. Personally I would think that running 5W-30 in the "new" 3.7l's wouldn't hurt anything, as not much had to have changed engine-wise between the years IMO. __________________ MY RIG: 03 KJ w/CAI, 12" Kicker Comp CVR & Ported Box, (2.5 springs coming :) ) BRO'S RIG: 89 YJ 4.2L 5spd (FRAME OFF RESTO IN PROGRESS!) |

I am not sure about the 0w30. Personally, I have been using 5w30 weight synthetic. __________________ Black Jeep Society #217 05 KJ - Black War Veterans Jeep Group #31 | |

Registered User | Would M1 0W-40 be ok to use? Reason I am asking is because I can get a great deal on M1 European spec'ed 0W-40. __________________ '06 Bright Silver KJ Limited 4x4 |

Posts: 83 | where's the great deal on 0w-40 that's what my crd uses. be careful running heavier oil in modern engines. back in the '70's we all ran 20-50 in our hotrods. a friend put 20-50 in his late '80's 3.9 dodge van and the lifters starved for oil because the thick oil could not be pumped thru the small oil gallies in the modern engine. |
