If you burn little oil and live in MN why do you want to run a HM oil? Do you have some seal leaks? Why not Mobil 1 AFE, or extended protection or any other non-HM...

NY/Madison avenue dictating things based on their perceptions of population densities in 4 season...

JK... they have a lot of information if you dig around.

If it were my car, I'd use M1 5W-20 at 7500-mile intervals. Excellent oil that can handle the interval easily. BTW, nice car!

to BITOG! I second Doug Hillary 's recommendation. If your owner's manual doesn't say anything more specific than an ILSAC 5w-30, that means two things: 1. Your engine is not too picky about oil. 2. You won't see much benefit if any from a "better" oil unless you drive it VERY hard. That said, if you can spring for a synthetic, don't let us stop you. It might allow easier starting on the coldest...

It looked brand new when I pulled it apart. We are not talking a 302 here. Not every car needs crazy pressure at hot idle. 38 isn't crazy. The SBC I help wrench on is in the 40's at idle with 5w40 in it as well....

The Amsoil 10W-40 is a very good product and if I had an application that called for a 10W-40 I would use it without hesitation. ryan2022, it would be an excellent oil for your 05 TJ.

A lot of people here including myself use Rotella 5W-40 on out gas cars. It's great stuff.

I forgott the why's? Great HTHS, extremly high end base stocks and high end additive packages that can go the distance! This applies to all of the ones I mentioned.

If you change oil at 3-5000 miles a TBN is not necessary, but if you plan to go 8-12,000 miles then a TBN may be helpful.
