A friend of mine just traded a RAV4 in on a new Grand Cherokee. He has $200 built up on his Toyota rewards credit card that they said he could use in their parts dept. He was considering stocking up on oil to use in his Jeep but the local Toyota dealer only carries Toyota 0W-20 in full-synthetic (he is strictly a synthetic user, won't even consider dino.) Does anyone see a problem with him using 0W-20 in his Grand Cherokee (spec'd for 5W-20)? I told him get onto some user forums and he might find others have done it without issues or even that Jeep had back-spec'd it, but I thought someone here might know off-hand.
Toyota 0W-20 in 2012 Jeep Grand Cherokee?

I wouldn't run it during the warranty period. He should just look in his OM.
The OM states:
Engine Oil Selection
For best performance and maximum protection for all
engines under all types of operating conditions, the
manufacturer recommends engine oils that are API Certified
and meet the requirements of Chrysler Material
Standard MS-6395.
Engine Oil Viscosity – 3.6L Engine
SAE 5W-30 engine oil is recommended for all operating
temperatures. This engine oil improves low temperature
starting and vehicle fuel economy.
Engine Oil Viscosity – 5.7L Engine
SAE 5W-20 engine oil is recommended for all operating
temperatures. This engine oil improves low temperature
starting and vehicle fuel economy.
NOTE: Vehicles equipped with a 5.7L engine must use
SAE 5W-20 oil. Failure to do so may result in improper
operation of the Multiple Displacement System (MDS).
Refer to “Multi-Displacement System” in “Starting and
Operating” for further information.
Lubricants, which do not have both the engine oil certification
mark and the correct SAE viscosity grade number,
should not be used.
Synthetic Engine Oils
You may use synthetic engine oils if the recommended oil
quality requirements are met, and the recommended
maintenance intervals for oil and filter changes are
followed.

That's a 5 year 100k mile powertrain warranty on a rather well designed engine. Lot of sacrifice.
Isnt this an oil site? Either 0w & 5w -20 multigrades are SAE 20 weight. If you cant use a 0W then you cant hot start the car either as the oil will be too thin. Not an issue. Period.

Not an issue mechanically. The issue is in maintaining his friends warranty. For the 5.7l his friend has, he must use oil that meets three requirements to maintain his warranty: 5w20, API certification, MS6395 certification. Period.
From the manual of my Charger:
"MAINTENANCE PROCEDURES
The pages that follow contain the required maintenance
services determined by the engineers who designed your
vehicle.
Besides the maintenance items for which there are fixed
maintenance intervals, there are other items that should
operate satisfactorily without periodic maintenance.
However, if a malfunction of these items does occur, it
could adversely affect the engine or vehicle performance.
These items should be inspected if a malfunction is
observed or suspected."
"Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacture only
recommends engine oils that are API certified and meet
the requirements of DaimlerChrysler Material Standard
MS-6395."
Notice how they even bold the word "required".

He can use it, but in the event of a warranty claim things could get messy.
Technically being a synthetic oil it will be a superior lubricant choice to the specified 5W-20 dino.
As RamFan points out, the issue in the very unlikely event that something happens to the engine, is that the oil hasn't been certified by Chrysler (MS-6395). But I don't believe Chrysler insists that you use their oil just that it be API certified.
Just thinking out loud here, but does M1 0W-20 meet the Chrysler MS-6395 requirement? Mobil says you can run M1 0W-20 in any 5W-20 application without voiding the manufacturers warranty. Since Mobil makes the Toyota 0W-20 you may have the weight of XOM behind you in any warranty dispute.

The use of the word "required" seems to be in reference to the service intervals, where as the MS-6395 spec is "recommended". This is the EXACT wording in my Ford manual with regard to the Ford spec. It recommends the WSS spec, but only "requires" the API certification. Obviously, it's his call, but personally I used the Toyota 0W20 while still under warranty--and it didn't concern me in the least. Of course, I never had a warranty claim, either.

In certain engines toyota 0w20 with its extremely high VI and high level of certain additives can cause more deposits than some other 0/5w20 oils.
I think it would most likely be ok but I'd probably use something else.
you can always buy the 0w20 and trade it to someone.

5w30 dealer bulk for my Pentastar so far, quiet as a mouse on startup.

Which engines? Which additives cause what deposits? Evidence?

Dumping anything labeled Toyota into a Jeep is just wrong!
Toyota service 0w20 oil is no longer 0.1% HIGH MOLY, IIRC. Oui? I dislike paying 7+ bucks a qt for Idemistu Subaru SM oil, but it runs so nice in the subie, I'm stickin wid it. Since I bought a case I hope it works well in the Honda Too.

Well if it makes you feel any better, as I mentioned it's made by Mobil for Toyota in the good old US of A.

The dealer might make your friend take a polygraph test. The service manger might accost him and pistol whip him till he talks. They have been known to do that if they suspect you put 0w20 instead of 5w20. If i was him Id get a bodyguard before he went in for warranty work.

I agree. Since Toyota's reliability record is superior and Jeep's is abysmal, one should not waste quality Toyota parts trying to bring a Jeep up to average.
