Pennzoil 5w-30 dino oil - meets penta 3.6 specs?

Hello All,

According to Pennzoil some weights of their dino line of oils meet the Pentastar 3.6 specs. They do not say which weight though. I can get the 5w-30 oil at Sam's for about $2.00 a quart. As I understand 5w-30 is approved for the 2015 engines...
Any info would be appreciated.

I am under the impression the 3.6 with VVT needs 5w-20. As JWBishop points out in his post, the heavier oil means the VVT is thrown off..ie, delayed valve lift and changed overlap...maybe not even full lift.

From the owners manual:
MOPAR® SAE 5W-20 engine oil approved to Chrysler Material Standard MS-6395 such as Pennzoil®, Shell Helix® or equivalent is recommended for all operating temperatures. This engine oil improves low temperature starting and vehicle fuel economy. The engine oil filler cap also shows the recommended engine oil viscosity for your engine. For information on engine oil filler cap location, refer to the “Engine Compartment” illustration in this section.

NOTE: MOPAR® SAE 5W-30 engine oil approved to Chrysler Material Standard MS-6395 such as Pennzoil®, Shell Helix® or equivalent may be used when SAE 5W-20 engine oil meeting MS-6395 is not available.

Tells me it wont HURT. But also that it wont HELP. Vis is more important every day in the close tolerances these things are being machined at - and VVT is very affected by oil flow, so I would only use the 5-30 as a last resort - that is down a qt and 5-30 is the only oil on the shelf for a hundred miles. not a solution for budget conflicts... or as a "regular" use oil.

This is the first I have ever heard of someone claiming 5w30 is potentially worse than 5w20. Most of what I have researched shows the opposite. I'm not saying anyone is wrong or right, but I don't see the minimal increase in viscosity being that big of a deal. I did my first oil change at 2k miles on my 2015 with Mobil 1 full synthetic 5w30. I'll continue to use the same oil at 5k mile intervals.

generally speaking I don't either. But folks more knowledgeable and smarter than I - do. And I understand quite well how the orifice in the lifter effects how it pumps up. That cant be refuted - a smaller hole means less exposure to oil pressure. Less exposure to oil pressure means less lift, duration and overlap. Raising vis has the same effect as reducing orifice.


That theory has been used to tune SBC chevies for YEARS (when HP/HV pumps are used because of a higher VIS (higher VIS is to make up the wider clearances in the bearings) a larger orifice must also be use (or more preload at install) - , the results are well documented - applying to a VVT is a small step fwd.. without a dyno its impossible to tell exactly what the change will yield in the torque curve. It could be better for all I know!

My 12 3.6 takes 5-30. Guess it depends on the year.

My 2012 says 5w30 as well, right on the oil fill cap.

Be careful with Mobil 1. While it is no doubt an outstanding oil that has proven itself time and time again, it is not MS-6395 certified. In the event of a warranty issue with the engine, this could be an issue. I have been a Mobil 1 user for most of my life in nearly every engine I have ever owned. My 2012 JKU gets 5w30 Dino Pennzoil because that is what the people who built the engine designed it to run with. I am not a huge pennzoil fan but it is what comes in the engine from the factory and it meets ms-6395.

You can use Castrol, Valvoline, Quaker State.......just to name a few that also meet the Chrysler MS-6395 Specs.

Walmart sells 5qt jugs of Valvoline Syn 5/20 for $23. Meets the spec.

I would like to stay with dino oil for the first 5-10,000miles.
At least for the summer months I think 5w-30 is better.

Thanks for your input.

So what changed, or what new information came about, that caused the manufacturers recommended oil to change from 5w30 in 2012, to 5w20 in 2014-2015?

Edit: Found this..
"From research off the net, the official reason is Mobil has not completed the two year field study mandated by the standard. Experts in the motor oil field are unanimous in their belief that Mobil 1 will have no trouble in securing the certification but until then owners looking to keep their fills compliant with MS-6395 (which might or might not have warranty implications) will need to seek other products."

One acronym....CAFE. They're chasing every little advantage they can to meet CAFE averages.....so thinner oil helps.

Correct. So ponder back some and think about all the high horsepower guys chasing every oz of torque they could all through the 70s and 80s while oem basked in the overkill approach lubrication.
Rule of thumb was lightest oil at highest volume through the bearings. And highest control of sling via scrapers. Keeping oil off the rotating mass lowers parasitic waste.
So mandates may have a good side effect by driving oem engineering into the same realm as high hp r&d.....
