Hi team,
I want to know if it's possible to use oil w5-30 oil on my jeep Cherokee kl v6 3.2 2014

Use anything you want, you are out of Warranty.
If you want the engine to run for a long time use what FCA recommends.

 

[Allstarlino]

Thank's
what does FCA recommend?

5W30 would be fine. Recommended, for gas mileage/emissions calculations, is 5W20.

More terrible advice.....the viscosity rating is not for fuel mileage its there for proper operation in colder temperatures



I wonder why the owners manual states what oil viscosity to use...........further more vehicles with VVT like the V6 are sensitive to oil viscosity, again gold star for being wrong

 

[Leems]

Then what about the 2.4L engine? The above explains only the 3.2L viscosity recommendation.

I use amsoil 5w20.
Was using Pennzoil platinum 5w20.

Its a vvt engine thats overly sensitive. Oil is cheaper than engines.

0W-20

Since the OP was asking about a 3.2...

Dude...

It may vary from country to country but this is from my owner’s manual and for the 3.2L same as my 14 TH:

I use 5W - 30 as I can’t find any 5W - 20 and I know others over here in Aus do also.
Cheers

Apparently, the OP is in Togo, Western Africa. I'm going to assume that it's pretty damn hot there, and doesn't get very cold in the winter time...😎

As Hawk27's post indicates, the manual for his Jeep with the same 3.2 engine, says it's fine to use 5w-30 if 5w-20 isn't available.

As far as your statement about viscosity in colder weather, do you really not understand that both 5w-20 and 5w-30 have the same cold weather (winter) viscosity rating? Are you really that dumb? The difference in the 2 oils is the upper rating which pertains to higher operating temps with the 5w-30 being more resistant to viscosity breakdown at higher temps.

Mark's advice was not terrible, but showed an understanding of the differences between 5w-20 and 5w-30. The main driving force for the manual's recommendation of 5w-20 is indeed for the slightly better gas mileage it provides. But if 5w-20 is not available for some reason the 3.2 engine will run, perform, and last just as long running 5w-30. In fact, if I were to live in Florida or some other area where temps are always high, I would run the 5w-30 for the higher protection it provides in those conditions.

Not terrible advice at all. The march to lower and lower viscosities for oil is primarily motivated by improved gas mileage. The improvement in oil chemistry is allowing the lower viscosities while still providing adequate protection at high temps.

Plus in this case 5w-20 verse 5w-30 the 5w refers to the cold temperature viscosity, meaning both of these oils have the same viscosity at the cold temperature used for the rating. The second number is the viscosity at the high temperature used for the rating. The higher the top number the better the shear strength of the oil at high temps which means better protection.

As far as impact on VVT systems I highly doubt that a change between 5w-20 and 5w-30 would have any impact. The 5.7 hemi, 6.4 hemi and 6.2 hellcat hemi all use the same VVT system yet the 5.7 recommends 5w-20 oil and the 6.2 and 6.4 recommend 0w-40. Other examples are the 2.3 Ecoboost recommends 5w-30 but when you order the High Performance Package which bumps the HP by 20 to 330HP recommends 5w-50. The 5.0 coyote engine recommends 5w-20 but for high performance use they recommend 5w-50.

IMHO, using 5w-30 in place of the recommended 5w-20 is not going to have any detrimental effects but could provide additional protection.

As most others have said 5w-30 is fine to use. And is easier to find as well. I have run 5w-30 many times when cannot find 5w-20. Which in today's market of products always being sold out is often. The pentastar is not overly hard on oil and runs well on any brand. My personal favorites are the Valvoline max life synthetic and Havoline pro-ds long life synthetic. Both have really strong add packs and offer great protection at a lower price than Pennzoil or Mobil1.
