Engine Oil

I’m sure there are plenty of oil gurus out there
I was wondering what people use in their JL I’m gonna start doing my own oil changes because the dealer is a rip off and apparently does not know how much to put in because they put 6 quarts of oil in my 5 quart jeep I was thinking about using Amsoil. They have a strong reputation. What do you guys think?

Amsoil is what I have used for years, and no problems at all. Do your research and use what you decide is best. There are a lot of good oils out there. Also, there are many videos put out by the oil manufacturers just use your own decision making power as they all say their oil is best. I also use Amsoil in my differentials and currently have over 21,000 miles and getting ready to change it again. I do the oil change and differential fluid change at the same time. Not necessary I know, but it's fun.

Any named brand 5w30 weight synthetic oil. Stay away from the 0w20, if you have the 3.6 engine.

There's a lot of good oils out you can use. For some time now I've been using either Royal Purple or Amsoil in all my vehicles.

I get the sampling kits from Blackstone and grab samples of my old oil as it's draining to send in to them for analysis about every other oil change. They run a pretty extensive test on your old oil to see what metals are in it and what condition your oil was still in when you drained it. I generally go 10-15K on my oil changes and have yet to get a report back that said I needed to change my oil sooner. I use Napa Gold oil filters and change my air filters regularly too.

EDIT: If you're going to go with Amsoil, and you also want to do UOA they sell pre-paid kits for Oil Analyzers Inc.

Also, highly recommend getting yourself a Fumoto valve (or one of the other good drain valve options) as this makes changes extremely easy and clean. Snap on drain hose, open valve, and drain directly into an oil recycle container. Zero mess.

You're suppose to change oil? ... in a jeep?


Next you'll be telling me I need to change,,, batteries or something. I suppose tires are a wear item.

I could explain why but if you want that, I’d go to the Bob is the Oil Guy forum and do some reading. Basically, definitely change every 5k miles or close to it if you do used oil analysis. I’m in the camp with my engine building background to lean toward at least a step higher in viscosity. For the 3.6, instead of 0w-20 when the engine initially called for 5w-30 in 2012, I’d recommend a 5w. For the at full operating temp viscosity, at least 30 and maybe a 40. I’ve stepped up from a great Valvoline Extended Protection 5w-30 to Mobil 1 5w-40, each progressively more quiet. The 5w-40 is stunningly quiet. Look up HTHS at 150°C specs. Either way, a premium synthetic is the way to go with a 5k interval.

I’ve also had the 2.0 for 80k miles. Within grades, some formulations are on the thicker side. I’d go that way if not 0w-40 to 5w-40 Euro spec oil if I still had it.

I've been using Mobil 1, probably the easiest brand to find.

Project Farm has done some oil test videos if you are interested in that kind of thing. I think changing at the proper interval is more important than the brand that you use. My JL is the easiest vehicle I've owned for oil changes.

If you don't use Amsoil, that thing will blow sky high in a matter of minutes!!! Forget what the book says!!

I like his videos. He does good work to help people. I’d also suggest The Motor Oil Geek. He’s an actual tribologist, an oil formulator.

Since you live in N.Y get 0w if you can instead of 5w, just for the below 0 period of the year. Also be advice that moving up grade just change the thickness range higher in the temperature scale while introducing higher thickness at the bottom of the temperature range. This is not a bad thing by itself until you get too thick and do more wear. Also a other thing to keep in mind when increasing thickness is the shearing that will result from forcing the oil in narrow passage. All in all, oil is more complex than just a brand, il is more inline whit environment, usage type, engine type and materials. Only recommendations I can provide is to use oil analysis to confirm you are on the good path or not in your oil selection.

Used Pennzoil Platinum 0w-20 every oil change at 7k miles for the last 70k miles. No issues at all, ever.

Concurred; Lake Speed Jr. is a great resource, just make sure you pay attention to what he is actually saying and don't just read a YouTube title and make invalid assumptions.

While I love Project Farm, his oil testing isn't the most scientific or "accurate"; however, that doesn't mean there isn't useful information in his oil videos.

$25 rebate on 10 quarts right now too. Not bad when it's priced at only $23 at Walmart for a 5 qt jug!
