no everything works great. no leaks for four years now other then a rear main seal thats was leaking before the switch to SYN
Interesting, I hear of a lot of people running into leaking problems when switching to syn after years of regular. Must be another internet myth.

Lots of people do that on regular oil changes. Some use kerosene, ATF (it has detergents in it), jet fuel, seafoam, etc... Is it effective? Dunno. Just remember most of these things suck as a lubricant, so you'd better not run it too long.

Nope.. not a myth at all...

The higher detergent properties in synthetic oils clean out the deposits and crud left over from running dino oils. So if there was a leak that was clogged with those deposits you will get a leak as those deposits are cleaned out.


BTW.. I run cheapo farm store 20w-50 and a Purolator filter. My Jeep leaks oil WAY too badly to run my own oil in it.

I run Castrol GTX High Mileage 10w-30 with a oversized WIX filter for better filtration.

I did however try Mobile 1 Fully Synthetic oil one time for about 1 day. But my oil pressure guage went off the scale (literatly). As in WAY to much pressure. I then changed back to coventional oil and have had no problems since.

Any of you guys ever hear of something like this?

Castrol GTX and Fram filter.

Every other filter I have tried leaks - every friggen one! I have heard bad things about Fram filters, but have never had any issues and have run them in all my vehicles for the past 30 years.

I change my oil about every 1000 miles or so as I spend a lot of time crawling at a low rpm with high engine temps, so the oil breaks down quickly.

I use Royal Purple in my diffs and tranny and regular ATF in the t-case. Diffs, tranny and t-case fluids get changed every spring.
