What oil do you use (synthetic)
 
Doing my 2012 JKU's first oil change this weekend, just wanted to see what others are using.

I used Mobil 1 synthetic in my 2011 JK.

What do you prefer and why (if you have some sort of fact to back your reasoning that would be great too)

:Thanx:

I just did Mobil 1 myself.

M1 5w30. :-)

I dont change my oil. Its over rated. I put gear lube 80w90 sometimes. Or sae30 from the lawn mower.

lolpetewtf 06-13-2012 11:20 AM

Mobile 1 15,000 mile 5w30

N3M0 06-13-2012 11:28 AM

Mobil 1 seems to be trending so far

Peepers 06-13-2012 11:43 AM

Amsoil XL

pkmcd99 06-13-2012 11:46 AM

Seriously though, I run K&N filter or Napa Gold with whatever synthetic national brand oil thats on sale at the time. This oil change consists of Synthetic Quakerstate. Time before was Mobil 1. Who knows what brand will be on sale next time

Norcal 06-13-2012 11:46 AM

I use Mobil 1 in all my vehicles. BTW, what is the manufacturers recommended oil weight for the pentastar in the JK?

+1 for M1

Everything else is really overkill, although high-end synthetics are certainly better.

It doesn't matter. Just run any reputable brand (Mobil, Valvoline, Castrol, Amsoil, etc) that you have at your local walmart, and get whichever one is on sale. Do NOT buy Royal Purple.

MikeK46 06-13-2012 11:51 AM

Since the motors take 6 quarts, do you guys usually buy one 5 quart jug and one matching 1 quart bottle?

Also, when I did my own oil change this past weekend, the dipstick showed full after 5.75 quarts, so I didn't bother putting the last quarter quart in, figuring that a little bit simply didn't drain out (Jeep was parked on flat ground, and I let the oil drain until no more dripping). Do you guys experience this?

I don't use Royal Purple, pretty much always only used M1. I do know people who swear by RP, what makes you say not too? Just curious :whistling:

I usually do yes, works out being cheaper that way.

Thanks. FYI to all Mobil 1 users, Costco is having a sale on Mobil 1. $10 off a case of 6. Sale is 6/14 - 7/8/12. Not sure if it is a national sale price or just my area here in norcal.

I have found this to be the case with almost every car/truck I have owned. I changed mine and like you said 5.75 put it at top of full mark.

It varies with filter size and time allowed to drain. Plan your oil change and do it in the morning before you start for the day if you really want a full six qt change

Jimmiseitz 06-13-2012 12:19 PM

The filter is a cartridge not a can, so I wouldn't be adding to much excess for filter. MOBILE1 is in my 12 jku

DFW6ER 06-13-2012 12:42 PM

remember if you're not opening and removing the oil cartridge BEFORE you open the drain plug, you're not getting all of the old oil out...this, oil temp and time you let it drain can affect how much it takes to get the level to full on the dipstick. IIRC I let mine drain for over an hour (Very hot oil) and still had oil dripping out of the pan at a frequent drip rate.

From what I understand, cold oil is more viscous and it's likely that a bit more will stay inside the engine if you try to drain it in the morning. Also, I heard that the contaminates in the oil settle when the engine is cold and some will stay inside the motor or pan.

More oil will come out if it's hot, since it flows much better and is less likely to stick to the walls inside the engine. Of course, some will always stay "stuck" inside the ports, pump, etc. no matter when you change it.

Synthetic for the Jeeps, I will probably go with Mobile 1 or Valvoline. Porsche uses no synthetic and has Rotella Dino.
