I run 75w90 synthetic mobil. Just pulled the top off mine and it looks brand new still.

Re: jerico dr4 fluid
 

how many passes are you on thanks gmonde

Re: jerico dr4 fluid
 

I use 75/90 Torrco and have hundreds of passes on my Jerico. Always looks new. But I guess Torrco is no longer around?

Re: jerico dr4 fluid
 

Well mine has 50 but our whole family runs Jerico dr4's and some are in the 200 pass range and they all look great and we all run the same 75w90 mobil.

I think any good 75w90 would be fine honestly.

Re: jerico dr4 fluid
 

Light weight red line. One Quart. Never had a single problem.

Re: jerico dr4 fluid
 

Mobil 1 75-90

Re: jerico dr4 fluid
 

I think any synthetic would be fine, but I really like the lightweight redline. I have been using that for about 6 years now. 1 quart. The big thing is to change it out periodically. I change it once during the season and again in the off season when we look it over. Never had any lube related issues, but I have seen some where they never changed the fluid out and cleaned the magnet. More junk running around inside is not a good thing. The magnet is strong,but it will get "full" of stuff if you don't tend to it once in awhile. I also added some good side drain plugs with rare earth magnets to grab as much debris from wear that I can.

Re: jerico dr4 fluid
 

is that redline's shockproof you guys are talking about?
i run it in my harley...

Re: jerico dr4 fluid
 

Yes. It's the lightweight shock proof gear oil. That stuff clings to the gears great. That's why you can get away with one quart.

Re: jerico dr4 fluid
 

Yes. It is sticky and slippery at the same time.

Re: jerico dr4 fluid
 

I use Torco RTF (racing trans. fluid) in all my manuals, car and truck.

Re: jerico dr4 fluid
 

I was running the red line shock proof but jerico told us to take it out and use mobil-1 75/90 instead.

Re: jerico dr4 fluid
 

I`ve also been using the Redline "light shock" in my Jerico (the blue stuff), I used to fill the trans to the fill plug, but I think I will try 1 quart next fluid change.
I also use Redlines "heavy shock" oil (the pink stuff), in my diff, as mentioned, this stuff clings like crazy! Earlier this year I pulled the diff cover after the car sat over the winter, and there was still oil clinging to the top of the case.
And speaking of Jericos, am I the only guy who has troubles with gear oil seeping out the front? Its not the input shaft seal, i`m guessing it must be from the cluster shaft area. It doesn`t drip onto the ground, but always seems to have a drop sitting at the bottom of the scattershield.Any easy fix?

Re: jerico dr4 fluid
 

No, you aren't alone, but it might be time for a new steel bushing in the front of the case. When that gets loose, bad stuff can follow. You can order a new bushing from Jerico if the case is ok. If you know someone that can machine a bushing, you can do a custom one if the hole for the bushing is loose.

Re: jerico dr4 fluid
 

They all leak. The one I have now is only a slow leak. My old one leaked so bad my son had to wipe it off in the staging lanes before the run. LOL

Re: jerico dr4 fluid
 

Sounds like mine. I got an oversized bushng from Jerico and it's a lot better for now. They make several sizes of bushings so it's a known problem.

Re: jerico dr4 fluid
 

I run 1 quart of Royal Purple 75/90 and so far so good. The more you change it the better but I do want to try the redline products to see if there's a difference. Also, we just put some silicon on the front countershaft area it seems to help with the slow leak issue just clean the area really good with some brake clearer and it should be good.

Re: jerico dr4 fluid
 

I got the HD case, top loader only, of A206 aluminum. No leaks.
