One of the few engines I would run 5w20 weight oil in . The manual does not state recomend it says must use or possible damage can occur . No brainer - use 5w20 oil

Ever see 5w20 come out of a warm oil pan... now that is like water and is the main reason I stopped using 5w20 oil . I'll sacrifice some miles per gallon for better engine lubrication . Forget the INTERNET [censored] about that engineers know better , at times yes in this matter of oil I think...

Originally Posted By: 901Memphis I believe all the engines all the way up to 2010 should be 5w30. I think maxlife is a good choice if your going to be changing it at least once a year. It sounds like the mileage will still be low per year. Even the ones with a few exceptions should use 5w30...

Originally Posted By: Trav Amazing isn't it that now 10w30 is considered thick oil. LOL Pretty soon they will be calling MMO oil fortifier. I know this 5w20 craze is funny . It has been near 100 degrees for almost 2 weeks, and I am glad I am running 5w40 - no problems at all been doing it for...

Originally Posted By: fdcg27 Just be sure to dump it before any real cold arrives, like by Thanksgiving. I've run much thicker than spec oils in various engines over the warmer months and have found that they typically make for smoother and quieter operation. 15W40 would be ok down to 5...

It has been 100 degrees here all week and it is expected next week also I am running 5W40 and IMO it is doing a bang up job . This thin oil fad around here is strange. Oh I run a 2011 Jeep Wrangler and have zero worries about the warranty and oil I use so save it.

Why use 5W20 ? Use a 5W30 or even a 5W40 this thin oil stuff is nuts IMO

Wolfs Head is good oil

Do I really need to use 5W-20 or 0W-20 oil? Truth, NO! Read on for technical facts regarding the use of 5W-20 or 0W-20 motor oil. Ford, Honda and Daimler- Chrysler specify 5W-20 or 0W-20 motor oil for most gas engine powered cars and light trucks. Is 5W20/0W-20 oil really necessary? 1. Here are...

Quote: and my personal conclusion is; You need an engine oil as thin as possible Why ?

Don't do it. Just because some can get by for some time doesn't mean you should do it. More than a few folks that are using 5w20 are reporting oil burning issues in Jeep Wranglers . Most vehicles in the US that spec a 20 weight oil aren't spec'd for a 20 weight oil in Europe- they require a 30...
