Whats the best oil to use?
 
I recently purchased a '12 JK Arctic. Only 645 miles on it, but when it comes time to change out the oil, what does everyone recomend?

When I was driving a '97 silverado and then a '06 G6, I used Mobile 5000 conventional oil (5W-30) and changed the oil every 5K miles.

Would this be a good choice to run on my new toy ('12 JK), or is there an oil out there that would be better suited ?

haha this is like asking what exhaust sounds the best

mfaas88 02-18-2012 01:55 AM

Hey now, I'm new to this! haha. Just didnt know if someone recommended a specific oil for wranglers

pluke the 2 02-18-2012 01:57 AM

the old man runs royal purple all day everyday.

ive run penzoil 5W-20 and Valvoline 5W-30 and Valvoline so far is hands down better.

mfaas88 02-18-2012 02:14 AM

What makes Valvoline better than the Penzoil?

I recently saw a thread of a jeeper's rig being 3 quarts low, and that JKs consume oil? does the 5W-30 weight cut down consumption more so than the 5W-20 weight?

i cant scientifically prove its better. its just placebo and knowing my jeep and how it runs.

on the weight thing, it cuts down on consumption.

Royal Purple in all my cars. Amsoil in motorcycles.

Use the viscosity (5W-30) recommended by the owner's manual. There were cases where the 3.8L engine in the 2007-2011s would use oil. Not aware of this with the 3.6L.

Hmmm, I'm subscribed. Interested in this as well. I used to do my own oil changes on my 71 Nova when I got it as a H.S. grad present in the 90's and used Valvoline because Penzoil would burn in it. I haven't done an oil change since I bought a new vehicle in the mid-90's though so no idea on what is good now or what works in the Jeep. It's so easy to get under there though I'm seriously considering doing my own changes again though.

Mobil 1 and Royal Purple are the two best oil companies on the market.

Now I have been reading that a full synthetic oil is recommended. I have new used it, always conventional because of hour stories of knocking ....any thoughts?

1. There is no "best oil" for your engine, but lot's of folks have oils they like. There is a correct oil for your engine which is specified in the owners manual as to weight and service standards and lots of engineering and testing hours on your engine by the manufacturer established these. If you change according to their recommendations or more often, you will be fine.

2. Knocking is caused by detonation and has to do with octane ratings and spark and has no relation to synthetic or regular oil.

3. Synthetic oils generally are "purer" in their weight rating and can go for longer change intervals and still provide wear protection equal to a shorter change interval with a conventional nonsynthetic oil. Some oils, frequently synthetics, use friction modifiers to improve fuel economy with engines that are made to use them.

Mobile 1 oil and filters cant go wrong :thumb:

Amsoil 5w30 would be the best oil for your 2012.

x10 do your research Amsoil has the best rateings..

pdubois64 02-19-2012 08:37 PM

Amsoil synthetic in all my vehicles. The JK will get it on the second change.

Arcticshaun 02-19-2012 10:24 PM

Yep, that was mine - 3 quarts low in 3k miles. According to everything I've heard here, Chrsyler says a quart per every 1k is normal, which is absolutely crazy... but its apparently an issue with only some of the early year JKs, & there's no known issue with the new Pentastar blocks.

I had an 09 and it never used a drop in the 20K miles I owned it. Used Mobil 1 syn in that rig. 1 qt/1000 is total BS. I'd be going for a new engine if that were the case.

ETA: I haven't seen your thread but if you haven't done it already get an oil analysis and see what's going on. Then you'll have some ammo.

I've always used Castrol Syntec in my vehicles, any thoughts? Thanks!

Phobos 02-25-2012 10:36 AM

Motul but you will pay for it. Several guys on my Wrx forum have tried everything from Royal Purple, Mobile 1, you name it and Motul had the best wear protection in the oil after testing.

pkmcd99 02-25-2012 10:40 AM

Another oil thread. In most cases its a brand thing when your comparing equal types of oil ie: synthetics v. synthetics... etc enough said.

jeepkingtn 02-25-2012 10:43 AM

Also what in your all's opinion is the best oil and air filter out there. Thanks again!

I have always used castrol syntec blend in all my vehicles, love the stuff...

I had dry knocks when I first started, but I changed my oil (first time since I bought it) with 5w-20 blend PLUS Lucas oil stabilizer...no more knocks, engine sounds ultra smooth....

Can't complain :)

needforspeed150 02-25-2012 12:00 PM

Well not specify jeep related but at our work we had a GM minivan that had the oil changed Valvoline 10w30. the filter was not put on tight enough and ended up that it loosened up and the engine lost oil. Our idiot driver thought when he saw a gauge at 0 oil pressure that the gauge must be broken. He never checked the oil. The gauge went to 0 at about 10 AM. He finished his route at 2PM. I checked it out and nothing in the pan. Changed filters, added oil.... That was on a 50k engine and it died at 250k... My money is with Valvoline. Don't ask me how this is possible I just know all the facts on this issue and the vehicle. It was regular oil not synthetic.

Just make sure you wash up if you turn in after you are finished changing your fluids, because oily to bed, oily to rise...

For 23 years, it's been Mobil 1 for me.
