Initially I was hesitant to pour 5W20 in my 08 Jeep calling for 5W20 only. I read that Ford Article, and a few others, searched this board, and went with the 5W20. It is working out well, so well that I use it in my back spec'd 93 Aerostar with 178,000 miles on it. I also read the article about the Ford guy who is opposed to using 5W20. He offered no proof other than his opinion. These topics always end in a thick vs thin debate.. To the OP, use whatever makes you happy, if it were my new Ford I'd use what they recommend and not look back. JMO
there is a TSB to use 5w30 in that Jeep my friend...do some searching and you will find it.
Would it be possible to post a link, or copy and paste it in a PM? It would be greatly appreciated. I have no problem making a change to 0W30. I just called my dealer and aksed about it unless they're pulling my chain they said use 5W20. Thanks
you can see here it was for the 'compass' model...my mother has a compass and step father has a liberty...they get 5w20 right now but I have made them aware that 5w30 might be better for our climate and also about this TSB...they will probably do whatever I recommend. I did not catch what model Jeep you had but this should say at least something about 5w20 & its protection in certain apps
