Synthetic Oil

[69GWC]

Cool thanks for the info, did not know it had 0w20 in it now, will run it out through the winter and change it out to 5w20 or 30 this spring.
Will give me time to reach what oil and filter I want to run in it, thinking Mobil 1 might be the bang for the buck on it.

I will start out with the factory recommended 0W20 in the 3.6 in the GC, as our old Acura has run it since new, so one less variety to keep up with. If it starts ticking, I will change as necessary.

Sooo what weight oil are you guys running in your 3.6s ? Will 5w30 work alright in it or are you guys sticking to 5w20.

Our 2013 Jeep Wrangler with the 3.6 had 5W20 in it for two oil changes (I think) then it has had 5w30 synthetic ever since. The last two changes have been 5 5W30 PUP and 1 0W40 PUP since it is over 80,000 miles now. It has been a good engine so far.

I think it's a GREAT engine from what I've been hearing and reading.

Where are you finding PUP 0W-40 in Calgary ,i've sort of been looking for it with not much success except for the local dealer

Cool thanks for the info, I am glad the heavier weight oil does not effect how it runs.

I went to 5w30 in our 2013 3.7 Mustang and it did not work well as it started surging as you gave it throttle somthing like feathering the throttle, switched back to 5w20 and it stopped doing it..

When you look at both Pennzoil synthetics Ultra and Platinum they are very low viscosity 5w30's, I can't imagine a situation where you would notice the difference in an application that takes 5w20. Most 5w20's are coming in right at 9 cSt, and Ultra Platinum is 10.3 operating temp, compare that to redline's 5w30 at over 12, there is no situation where Pennzoil 5w30's are gonna be the better choice over 5w20. The real news is would a viscosity of 1 point going to give you any additional benefit, who knows right? I'd say my wife's car likes it for whatever reason, rattles on 5w20 pup or even redline but that 1 visc makes her vehicle smooth.

Auto Value in Midnipore carries it but that is the only PUP they do carry. The manager told me he carries the 0W40 specifically for the 6.4 Hemi so maybe try an Auto Value by you.

I've also seen some UOAs where either PP or PUP 5w30 is in the mid to high 9s for visc at 100C...

I was using a 4/3 blend of 5w20 PUP and 0w40 SRT PUP, but switched to Amsoil SS and decided to go with 5w20 (for the winter) and my oil oil pressure went up a tad at idle in gear. I swear my Hemi feels smoother and quieter, although I've never had a tick.

I'll probably switch to 5w30 (Amsoil SS) for summer.

I guess maybe I should’ve paid more attention to mine to see if my oil pressure went up from what it was after switching the Amsoil SS 5w20.

But see, I never could tell if my engine got any quieter or really even ran any smoother on the Amsoil from the pup 5W20.

Maybe it’s because I was running just a straight 5W20 oil and not mixing 5W20 with 0W40? Not really condemning that practice, I was just always told not to mix oil weights but whatever, I’m just saying it’s not something I’d be interested in.

But I’ve never had that warm idle tick either and the only time so far where my engine has ever really ticked for a very short period was only from starting it up a second time not long after starting it up for a short while the first time. As long as I don’t do that, it doesn’t tick.

I’ll probably switch to 5w30 (Amsoil SS) for summer.

If that Amsoil SS 5W20 is pretty good stuff with a good additive package, supposedly lots of moly and is PAO based at all that then why the purpose to use the heavier 30w oil? Prevention is one thing but since you said you’ve never had a tick, I’m just just curious, as usual.

Go to a jeep forum they have had their fair share of issues mostly cylinder heads and oil filter cooler housings. I have had 4 3.6’s and did suffer the cracked oil cooler housing.

Also, some cam and follower/hydraulic lash adjuster trouble.

Our GC 3.6 has a very annoying surge at steady throttle. Not much chatter about it on the GC forums, but lots on the Wrangler forums. It's worse on cruise control, as the cruise is pretty abrupt, needs a bit of smoothing in the programming. To me, it is very aggravating. Some may not notice it. I'm glad it's my wife's daily driver. Also has a bit of torque converter shudder, mostly when cold.

Just finished my summer run on Amsoil 5w30 in my Toyota 4Runner and she loved it; manual calls for 0w20 but the engine sounded like crap under throttle with the 20 weight. Just put my winter blend of Amsoil 0w30 in yesterday’s. All is good with the 4.0.

Sounds a little on the lean side, my 06 chevy 5.3 was like that unitll I put a tune on it and the surge went away.

Have not drove our GC enough to notice ifbits like that but it would not surprise me with the epa and cafe standards.

Welp! First time on Redline 5w30 and it's getting cold. About a 1-2 second chatter at startup when it hits about 20 degrees or lower in the mornings. I've only had a few mornings of that cold though.

Have about 2500 miles on the run and nice and quiet anything warmer. I see Redline 0w30 in my future.

Little background, I have never had a hemi tick or abnormal noises and have about 85,000 miles. Have used srt, royal purple, and amsoil filters. Have used PUP 0w40, RP HPS 5w20/30, and Amsoil 5w20.

Quietest the valvetrain has sounded especially with headers is this Redline 5w30 run and the second closest was PUP 0w40.

Yeah if you're in WI you will probably end up with RL 0w30 at some point. I notice a good decrease in cold start noise with RL 0w30 than 5w30 and our winters in MA are not as cold as WI.

BUT with that in mind I've ran RL 5w30 in the winter for a few years before now with very good UOAs in the spring so although its noisier than 0w30 its not doing any harm to the motor.

 

[brad_12]

Glad you chimed in. You were the first one I thought of that switched to 0w30. That's probably going to be my oil next year then.

It's crazy just last week we had mid 70's and this morning it was 25. It's showing nicer weather through November though mid 40's and 30's.

 

[Hemi395]

How does this HOLD any water ?? My 6.4 has 0w oil and noisy as hell on start up ??

How does going from 5w to 0w prove anything ?????????????????


Funny how folks are SO quick to claim a WEIGHT change as a fix VS BRAND they are using............................
