Take the Jeep out for a quick drive around the block before changing the oil. I do about a 2-5 mile drive to heat things up.

What type of oil do I use.

When ever I buy a new or used vehicle, the first thing that I do is replace whatever oil/filter that is in the car/truck with Mobile 1 or AMSOIL, plus filter's.

Seriously though, why the issue with RP? I run it in my flat tappet motors due to the extra ZDDP ever since EPA forced oil companies to drop it below 1200 ppm. Is your concern the ZDDP reaction at the Cat or just the price per quart?

For you scientists out there with no personailty, I was being fececious. Hoe the F in the right mind is gonna expect all 6qt to drain out under most circumstances with an oil change. Also, who the F is gonna leave there vehicle to sit for and hour plus with the drain plug out waiting for the oil to stop dripping. Sometimes you folks are ridiculous. PS, there are about fifty other threads that also argue brand and procedure already. To the OP; use a new oil of your preference and within your budget. Even conventional oils, if you desire to use, can give great protection for your jeeps engine. Mobil 1 is popular and well advertised, great product. Use what you want, just be vigilant to drain it out when its time and you wont have any oil related engine failures. To the smartie that said his filter is a canister type and does not vary in size, no kidding. I was writing generically speaking regarding reasons capacity can vary.

Well....I had time to burn this past Sunday morning......so I let the oil drain for about 80 minutes to get out as much of the spent oil as possible. I don't do work on my vehicles unless I have time to spare....you never know when something might break....but that's just me.

Anyone see the metal content in the oil after their first change? Normal but still...shocking.

I saw a 1/4" long piece of what looked to be silicon but no metal. I was specifically looking for it. Even slid a magnet around in the oil. Came back with an oily magnet but no filings

In the Jeep, I am using Pennzoil Yellow Bottle but will move to Valvoline DuraBlend. I use German Castrol in the Subaru and will probably switch to Pennzoil Ultra in the Suabru and the 4Runner. Maybe the Jeep too....someday.

Snakeoil crap product. False advertising and poor performance. I posted a ton of data in the other oil thread...let me see if I can find it. They are the "fram" of motor oils. Since they are the same price, or MORE than other leading brands, I see absolutely no reason to run it.

I do. I do it on a cold motor (all the oil is in the pan), set up the drain pan, undo the drain plug, and go about my day, letting the oil drain all day. Then, I come home, put the drain plug back, fill her up, and that's all she wrote. If I am in a hurry, I'll do the oil change another day. It's just OCD. There is no need for that. When the drain is dripping less than one drop every 10 seconds, go ahead and put the bolt back in, and fill to the correct level.

This isn't even the "evidence" I am looking for (their oil has been known to "burn" and cause tons more deposits than other oils...but like I said, something like Mobil 1 or Valvoline is BETTER and cheaper. If you want to run the best, run Amsoil.

Interesting.

Had not heard that opinion of RP before. Are you running any flat tappet cam style motors or strictly new roller cam/lifter/chain systems?

What was your negative experience? I'm currently running RP in my 68 mustang 390 without problems.

I'd hesitate to say one oil is the best for all engines. Different engines seem to prefer different oils, and this can vary even in the same engine over the lifespan of the engine....UOAs are the best way to see what gives you the best OCIs, least ammount of wear metals. You may find great results with AMSOIL in the BMW engines....I can say the best UOAs I've seen in the 3L Duratecs with Mazda heads are from Schaffer Supreme.

What we need on this forum is a dedicated UOA thread broken down into each engine type. After many dozen UOAs get posted on the more common oils, a superior oil should appear.

I am not. However, any motor I have ever run that is sensitive to oils (race motors, classic cars, etc) ALL get Amsoil without question. I have said a number of times, modern cars like the JK can run on any good synthetic without issue, but Amsoil is the best motor lubricant currently in production today. It is superior to ANY other oil on the market in EVERY category except one...arctic weather cold starting, where it comes in at #2. I have seen first hand what Royal Purple is capable of doing on modern cars, and have concluded that it is a terrible product. Not only that, they misrepresent themselves. They are NOT a synthetic oil. They are a DINO oil with SYNTHETIC additives. This pissed me off as well, as they mislead customers to thinking that they are buying premium synthetic oil. I have changed cams on a car running RP and the results were disastrous. It looked like snot. I have also put it into another car, and immediately heard the lifters like they were amplified.

You might not have problems with your mustang, but what are you basic that information on? Have you ever done a labtest? Use blackstone labs. It's $20. Have you tried another oil to see if you notice smoother performance (ie Amsoil?)

I will loosely agree with this, but it is not because of the car. BMW motors (of high compression motors in general, including sports car motors generally run hot. The current breed of BMWs (turboed models) run REALLY hot. As a result, an oil that performs better in the head will be superior in said car. I agree, the application does indeed matter. However, with modern engines, and modern oils, IMHO, any good quality big brand synthetic is MORE than good enough, and you will suffer no ill effects from ANY of them.

I'm pretty sure Napa synthetic oil is just rebadged Mobil 1, as are most "dealer" branded oils...they are just rebadged big brand names (ie Mobil1, Valvoline or Castrol.)

This for information only, I do not wish to (and will not) start a discussion on this.

I noticed several posters indicating they were planning on switching to Mobil 1. For 2012 models this oil is not approved. The owner's manual indicates that:

"… the manufacturer recommends engine oils that are API Certified and meet the requirements of Chrysler Material Standard MS-6395."

Mobil 1 does not list this on their spec sheet; from my understanding the reason Mobil products are no longer 'approved' is due to the Chrysler bailout where Chrysler stiffed Mobil out of quite a bit of money. The 'approved' oil is now Pennzoil, so you are left with the Pennzoil synthetics if you go to the dealer. I bring this up since Chrysler has a little reputation about their warranty.

Like I said, this is just for information; it’s free so you got your money’s worth, interpret it as you wish.

I would LOVE to see Chrysler deny my warranty because I ran Mobil1. I would have a field day with them. While I can appreciate the post, they would NEVER EVER win.

Here is some more food for thought. Mobil is one of the most widely used/supplied oils in existence. Mercedes, Porsche, Ferrari, Lambos, Honda and Toyota ALL use Mobil oil (some companies like AMG model Mercedes actually have the Mobil logo on the oil cap.) By law, Chrysler cannot force you to use Chrysler to service your vehicle. They can only force you to DO the service. Now, there are plenty of Garages that use mobil as their default oil. 95% of Chrysler customers are NOT car enthusiasts like us. They walk into a local shop and say "good day sir, I need an oil change." They have NO idea what oil the shop will use, and they don't need to know. There is no way on gods green earth that Chrysler could ever deny your warranty based on the fact that you used an oil from a company that they don't like.

I haven't seen Lucas mentioned yet. I've used mostly M1 in the past, and Amzoil deserves its legions of fans. I've been a fan of full synthetic ever since it hit the market. If you've just got to have dino oil, add a can of Slick 50.

Lucas products is another snakeoil. Don't ever put Lucas products into a modern motor.

Amsoil Signature Series 5W30, or at least that's what I will run when I make the switch on mine. I already run it in the Infiniti and the Toyota.

Looks like Havoline, Exxon and Chevron rank very high. Wondering why they're not used more often

They are not as easy to get. Most big box stores stock Mobil, Castrol, Valvoline, Pennzoil, and usually that's it. They can't possibly stock them all.
