First oil change for my 08 Wrangler

[afoulk]

I just bought a 08 Jeep Wrangler Unlimited and had a few questions about changing oil in it.

#1, would it be a good idea to change my oil after 500-1,000miles or so, just to get all the [censored] out of the engine from break in, or just run it to 3,000miles and then change it?

#2, can I switch right to synthetic at my first oil change?

#3, I'd like to use Schaeffers Supreme 9000, but my manual recommends 5w-20 under all weather conditions and the 9000 only comes 5w30 or 5w-40. Would the 5w30 be ok for my engine, and would it drop my fuel mileage at all since its slightly thicker (I doubt it will)? Their 5-30 9000 does meet chrysler MS6395 which my manual says to look for. Or should I just go with their Supreme 7000 which does come in a 5w20? I'd really like to stick with a full synthetic if possible though.

#4, and my final question, are Purolater's Pure One filters any good? I don't like anything my local Autozone sells, and while Napa Golds are good, my local Napa doesnt have hours that fit my schedule to well. Thanks guys.

1. I have been told that with modern machining, this is unnecessary, however, I have also heard that it is still a good idea. I drain the factory fill at 2000 miles on most cars.

2. Yes. I have done that on several cars. The stories about synthetic preventing proper break-in can't be true if every Corvette, Porsche, Benz, and BMW leave the factory with synthetic.

3. I have no opinion since I am not familiar with Schaeffer products.

4. PureONE filters are good.

1. It's up to you. You probably won't know any difference either way.
2. Yes, I've done it on three cars now and no issues.
3. No idea, but try PP at rebate prices from P-Boys if you want something cheaper.
4. Yes, I use them on my 2 cars and a bunch of my friend's cars and have been proven here.

Ok, upon fruther research, it looks like the Schaeffer's Supreme 7000 only meets Chrysler MS6395L and 6395M requirements, doesn't say anything about just 6395. Would that be ok to use? I tryed google'ing the L and M requirements, and couldn't really find how they differ from 6395. Their 9000 meets the MS6395, but like I said above, its a 5w30. I'm just worried about having warranty hassles since the main reason I bought a new 08 was because of the lifetime powertrain warranty. I'm kinda torn with what to do as I've always been a big fan of Scheffers stuff, but don't wanna run into problems down the road with chrysler.

Sounds like we've been down the same road. I have a new 08 Liberty which calls for 5W-20 under all conditions. I changed the oil out at 500 miles and went with Pennzoil yellow bottle 5W-20, at 2000 miles I changed it again and went with PP 5W-20 which will stay in for 6 months since I won't hit the mileage. The Pure one filters are great and that is what I am using.

I wouldn't use a 5w30, if anything ask your dealership service manager about using 0W-20 oil. My guy told me that it would be OK even though 5W-20 is called for. I was planning on using Mobil 1 0W-20 for the winter months.

HTH,

Document everything and run what the factory recomends. I have an 08 wrangler and it doesn't have the lifetime warranty because I bought mine used with 2800 miles on it. The oil change light was on when I got it so I changed the oil with Pennzoil 5w20.
I intend to run 5 or 0w20 for the life of this minivan engine. In the texas heat and churn it up and down the sands of Padre Island now and then. Took my doors off in May and I will think about putting them back on in the fall.

The jeep is just plain fun. That's the point.

Mines a regular sized 6 speed manual X with a softtop. Congrats on the jeep! http://i3.photobucket.com/albums/y79/Bryanccfshr/042008028.jpg

Well, most of the new engines show higher "wear numbers " so it can't hurt.Why syn oils? What real advantage do you expect to get from the extra $$ spent ? Have you been studying up the UOAs that have been posted? have you noticed any real differences in the wear numbers at manufactures recommended oil change intervals?.It is a real waste of $$$ to use syn oil for the mfgs oil change intervals unless syn oil is recommended considering possible warranty problems not following service recommendations. Jeep wranglers aren't the vehicle of choice when mpgs are to be considered .What about the rest of the driveline? Schaffers dino oils probably outperform most syns based on UOAs.

I was mainly interested in synthetic for my jeeps engine because they run so hot to begin with, and I plan to offroad it too and realize that that isn't all that easy on the engine either. When the time comes, I plan on switching to schaeffers gear oil for my diffs and their atf for the t-case. I don't have to many options as far as the transmission goes, as they require atf +4. I just like to get the best mileage out of it as is possible. I plan on keeping this thing a good long time.

Thanks for the congrats Bryan. This is my second jeep, first was a 05 Rubicon. That one was lemon, but so far so good with this one. I wanted a 6spd, but after driving one, I didn't care for the way they shift. The new electronic throttle hangs onto the revs to long when letting off to shift and makes the whole shifting process to jerky. In the end, I'm pretty happy with the auto.

Another neat think with these JK's is the huge wheel wells. I probably won't lift mine at all for a while and just upgrade to 32 or 33" tires eventually and get some rock rails and have fun! This is our first Jeep. We have been with Toyotas for a long time but Jeep is alot more aftermarket friendly and affordable to have for a toy.

The engine management system seems to calm down with miles. My wife who hadn't driven a stick in over ten years was able to jump right in and drive it. Actually I think the jeep is now hers..

Feel free to run Penn Platinum 5W20, or if you have an Amsoil dealer nearby their XL 5W20 is rock solid too, and priced pretty well. There are a lot of great 5W20's out there today I just don't have any experience with the Schaeffers 7000. By the way once you modify your jeep you will lie to yourself a lot by thinking, "Oh if I just do X that will be perfect then I won't have to do anymore!"! There should be a jeep aftermarket anonymous support club for us jeep owners!

 

[3putter]

I think you've answered your own question. Why would you possibly use something that could cause you warranty problems?
So stick with the flavor they recommend. Duh.

 

[Greaser]

If it were my jeep I would use Pennzoil Platinum 5W-20 and Napa Gold filters on the engine with any quality ATF and gear oil that you like in everything else...Schaffers is good stuff.To keep the warranty up buy all your stuff ,and have the dealer change it out and record it if you like,thats what I did till I was out of warranty.194,000KM on my 01 TJ and 254,000km on my 99 XJ and they still run like new!

My wife's '07 Wrangler Unlimited gets Mobil 1 5W-20 and Purolator PureOne Oil Filters. She puts about 10K a year on the vehicle so it gets an oil change every 6 months. Synthetic is probably overkill here; I could easily get by with conventional 5W-20.

You have a Jeep, don't be too concerned about fuel mileage.

I changed the oil early but that's just me; these days I don't think it makes a huge difference.

Enjoy your Jeep!

 

[artificialist]

For the ATF, you do have one great option. Amsoil universal ATF.
Also, be sure to change the gear oil in the front and rear differential with whatever viscosity is needed. Then, change the transfer case oil.

 

[salesrep]

Can't be a bad idea to change the oil too early. Eh.
You'll not void any warranties running Schaeffers.
If you really, really wnated to run the 9003 syn 5-30, the loss in fuel economy would be miniscule. More to the point, I'd run the 704 5-20 blend http://www.schaefferoil.com/datapdf/704.pdf . This is the viscosity the engine calls for, run it. Same add pack as the 9003 and a heck of an oil, don't get caught up in " all the way syn" as your only criteria.
Run the 293 75-90 http://www.schaefferoil.com/datapdf/293 75W90.pdf in the diffs and the 204sat alltrans http://www.schaefferoil.com/datapdf/204SAT_r.pdf in the transmission. You will get the maximum fuel economy you can running our fluids, protect your equipment, and be able to change at your convenience. Consider our 131 or 131c for your fuel as well.

My biased :2cents:

 

[afoulk]

Salesrep, can you tell me what the difference is between the chrysler MS6395, 6395M, and 6395L requirements are? I was starting to lean towards the Supreme 7000, but saw it only meets the L and M requirements.

I will definately switch to the alltrans ATF when I service the transmission for the first time. I didn't see that it also meets the +3 and +4 requirements.

As for the gear lube, do you make a 75w-140? I'd like to run this in the rear axle as my manual calls for that if you do any significant towing or offroading, which I'm hoping to do in the future.

And finally, is there a dealer on line for Schaeffers where I can purchase all this stuff without having to buy huge quantities of it? My closest dealer is about a hours drive away and they are mainly a farm implement dealer and don't stock most of the stuff I need. I'd have to order the stuff in bulk from them, and wait until they are ready to put a stock order in until I could get it. I know I shouldn't be this overly concerned about what fluids I'm running in my Jeep, but I want it to last me as long as possible, and I just like the added piece of mind the Schaeffers gives me. I loved the stuff when I had my dodge cummins. Thanks for your help

 

[salesrep]

Not off the top of my head.
It exceeds atf 3 and 4.
The smallest quantity we produce in the 75-140 is five gallon pails.
I reckon that he would be your closest dealer.
