Hey guys,
just a quick heads up about my last experiences with my Wrangler JKU. I had the Oil Change Required light coming up a few days ago and decided to give the beast what it wants - fresh lubrication. Looked up several forums and what I found was, that the manufacturer (which is Chrysler) made a change for Pentarstar engines from 5W-20 to 5W-30 and that some people had tried out 5W-40 full synthetics and achieved good results with their choice. After a lengthy research process at Autobarn (they have a lot of different oils) after thinking about it I decided to give Penrite 5W-40 a go. It's recommended for cars that use 5W-30 but gives it extra protection in hot environment. And as I plan to go to Fraser over the holidays it didn't sound too stupid.
I also bought a couple of genuine Mopar Oil filters from ebay (80 bucks for six). Replacing the oil filter in the new pentastar engine is easy as stealing a babies lollies.
The Oil change was a quick procedure, have to admit that my mate Adam did it for me since he had the tools and gloves. Will do it definitely myself next time. I remember how much work it was, changing it on my Pajero. I had to take off the bash plates to get to the oil filter. Now I just have to pop the bonnet, take off the plastic engine cover (the one with the big 3.6 VVT emboss on it) and unscrew the filter cartridge.
How much engine oil for the Pentastar Engine?
We couldn't find any metric figures on the web about how much oil the engine needs. Everywhere we looked people just stated 6 quarts. Luckily good old google does a calculation which states "5.67 Litres".
Back to the oil topic. I sank my fingers into the old oil pan and found that it was pretty black (like char coal) so it was definitely due for a change. With the new oil in the fuel usage immediately started dropping a tenth of a litre every 2-3km and now I am sitting at around 10.6 L/100 km. The engine seems to be quieter and and causes definitely less vibrations. I am happy with that and will keep you updated after our island trip. Let's see how it behaves in the heat. :)
