Oil for 2.8L

I just went and bought some penz oil 10w30 for my 2.8 v6 and now my dad says it should have 5w30. I bought the 10w30 becuase thats whats on the penz oil sticker in the window. whos right? from what i herd those people that work at penz oil are not the smartest people in town any ways.


thanx for the help

Re: Oil for 2.8L

well the 5w means that it is thinner at freezing, meening itwill flow easier at lower temps, but 10w is fine, i run castrol syntec 15w 50 in my 2.8 and it works just fine.

I have ran Havoline 5W-30 year round in my 89 S-10 truck since I bought it new. It has almost 200,000 on the engine and I have never turned a bolt on the engine except to put on a new water pump.

Re: Oil for 2.8L

I have used 5w30 in my 1986 2.8L engined Jeep Cherokee during really cold winters but most of the time it's 10w30. I also tend to change to oil more frequently because of the small 1/2 qt. AC/Delco PF-47 filter.[img]/wwwthreads_images/icons/smile.gif[/img]

Re: Oil for 2.8L

as for the oil filter...have your part store cross ref a QS3980 it is a longer filter (it's the one I use )but it clears and is much easier to install and take out..Fram also uses the 3980 part number..
I,ve been in the Quick Lube biz for 16 yrs.. I need help..lol But the syn..oils are the way to go,I've never notices a power or milage gain but it just holds up so much better. Also check into Redline Oil, it cost a little bit ,but if its good enough for top-fuel cars ,its my choise.

Re: Oil for 2.8L

Thanks for the tip but I don't think a longer filter will fit in that tight access place on a 2.8 Cherokee. There's barely enough room for the PF-47.[img]/wwwthreads_images/icons/crazy.gif[/img]

<font face="Comic Sans MS">If you could please, ask him for a detailed explanation of how that happens, I'm interested in that, having never heard that before. [img]/wwwthreads_images/icons/crazy.gif[/img]</font>
