Well my jeep is in getting new gears and im going to be using royal purple diff fluid and after reading some things about royal purples other products I was thinking about using their oil and trans fluid in my jeep and pathfinder.

Currently I work at a small town sunoco garage once a month so I do my own oil changes there. I use sunoco 5w30 oil and a napa oil filter.

So I wanna know what you other jeepers are running in your rigs to see if its worth using the royal purple and a better oil filter.

 

Wix oil filter and 5w 20 Castrol Oil.

 

I've been using K&N oil filters for years on all my vehicles with no issues.

 

I use Mobil1 5w20 and either Wix or Purolator filters. No issues here.

 

does the oil filter really make that big of a difference?

 

Motorcraft 5w20 Full Synthetic Oil with a Mopar Filter. Trying a Motorcraft and FRAM filters resulted in a engine knock/tap and a oil light randomly popping up on cold starts.

Switched to Royal Purple 75w90 for the diffy fluid . Proably go with Royal Purple when I get ready to change the tranny fluid

 

Napa synthetic & Wix filter here. So far so good. I compared the OEM filter I took off with the Wix & the baseplate was identical.

 

Penzoil Platinum 5w30 with a Motorcraft FL400 filter changed every 5,000 miles.

 

same, like some one else on the thread said, the extra 3-4 dollars for peace mind....

although, i wonder how much of a difference it makes to have a full synthetic and having some of those 99% synthetics that are a third of the cost

 

I wasnt having much luck with Mobil 1 5w20 synthetic oil, 4000 - 4500 kilometres and the change oil light would come on and yes the oil needed to be changed, didnt have this problem with the dino juice the dealership used. I have heard rumblings on here and on the other websites that Mobil 1 synthetic isnt true synthetic and its derived from what they call "crack stock" or bottom of the barrel oil, I have no proof of that and by no means am I bashing Mobil 1 or anyone who uses it. Decided to go with Pennzoil Platinum based on the advice of several mechanic friends, still using Napa Gold filters.
