just dropped low mileage v6 thirds in front and rear. Also just ordered an aussie for the rear. I think I am going to start running synthetics in the drivetrain. Last 30,000 miles I've been running regular 80w-90 gl5. I thought the transmission was a lost cause, but I think its got some life in it. So i think I amd going to start running synthetic in that and the t case. Is it worth running synthetic in the front diff If I manual hubs?

 

only you know if it is worth it to you.

I have been told by several oil company reps that synthetic needs changing just as often as regular oils .

with gear oils it was just a pain having different kinds i just buy 85W140 and use it in all the gear boxes.

It works for me.

just like any oil it gets dirty it gets water in from condensation .

The only thing I use is a semi synthetic in my 7.3 foe engine oil.

 

After initial setup you'll want to run normal stuff for break in and change to synthetic after 500 miles. I use Royal Purple cause it tastes good

:wabbit2:

 

Tastes good compared to what??

 

the royal purple bottle does look pretty tastey. I've Just never had the balls to try it...
