Where do you buy Redline? I've heard it's good, what's the story?

depends how ugly she is and how close to closing time !!:eek:

Mobil1 75W-90 Difs, Tranny,TC

Any major brand 75W - 90. I've run it for years with no problems.

For my trail rig, I run any reputable brand of 75-90.
I have been sold on, the advantages of running synthetic lubricants for years. I run synthetic engine oil in all of my rigs. I also run synthetic gear oil in my F250, and the motorhome, where the demands of towing, and long hauls, can be hard on the gear oil. If you arent flat towing the rig, I think its more important in a trail rig, to change the gear oil regularly(especialy after many water crossings, and/or mud boggs), than to spend $7 a quart for gear oil, and put off more frequent changes.

ok so which are you telling the guy, use or not? You say you run syn lube, and then you say you think it's more important to change it regularly and not spend extra $$$?

Nobody said anything about running syn lube for the advertised longer change intervals.. I run it cuz it gets damn cold up here and the dino lube gets to be non-pourable.. And the added protection under high pressure gear contact syn lube provides.
:emb:

But what do I know about water crossings

More water

Ummm, snow covered mud

I am not saying to use syn oil for longer change intervals.
I am saying that no gear oil is worth a crap, once youve had water introduced into it. Although synthetics are much better at protecting the components, once moisture has contaminated the oil, It is still no magic bullet, and should be changed quickly. You cant completely waterproof your axles. So I am saying that more frequent and less expensive oil changes are gonna help your axle components more, than one expensive syn lube change at the start of the season, and expecting it work magic for you, even though its contaminated.
As for the tow rigs, the syn gear lube is worth the cost, due to the fact that it doesnt break down under high temperatures, as can be generated while towing.
Now if you want to pay the money for frequent gear oil changes with synthetics, go for it, but I have driven through the mud and water once or twice in my life also, and I can tell you, that you will contaminate the gear oil, when wet wheelin.
As far as the cold weather, well those of you living in Alaska would have a different set of parameters that you may require due to freezing temps. I am talking though about the average Joe and his trail rig. I still believe good maintenance of the diff lubes more important than high dollar synthetics. If you can afford to do both,..fine.

By the way nice pictures of the rig, in the snow, mud , and water, but now lets see the pics of the frothy white swamp water, syn oil soup, churning away in the pig, after a season of wheeling in all that crud.

You are reading the post in this thread right??? cuz it looks more like your just making it up as you go.... Where did you read that I run the same lube all season??? where did you read I do not pull miant on the vehicle after a run that contaminates the lube? I never said antything like that, no did I imply you could run syn lubes and get longer change times, use it under water, brush your teeth with it, mix it with rum for a nice on the trail drink..

My comments to your post were because YOU wrote this
"For my trail rig, I run any reputable brand of 75-90.

and then in the same post wrote"I think its more important in a trail rig, to change the gear oil regularly(especialy after many water crossings, and/or mud boggs), than to spend $7 a quart for gear oil, and put off more frequent changes"

Here lets make this simple..(for those in need)

YES use Syn lubes
YES change it if it gets contaminated
YES read the thread and reply accordingly
NO do not look at a pic and try and figure out the meaning of life


OK thats all clear now
:flipoff2:
