OK, I'm about to get some oil for my rear diff, and my transmission. What kinda oil should I use? I've been told that the redine stuff is really, really good, and that it actually can help increase synchro life? Is this tru? i've tried to do some searching on here, but, I haven't found alot of info yet. Now, along with what brand, what type of oil should I use in each? I'm going to change them out in I believe 2 weekends from now, so, I've got a little time to order good fluid online if I have to. Also, where is one of the cheapest places to get these said oil? I appreciate your input, guys.
Oh, ya, as far as engine oil. What do you guys run in your motor's? I'm going to run Castrol 20W-50, I know it's a good oil, and I'm one of those people who will change it about ever 2500k Anyway, so, I don't think longevity is really a question here. Just curious.,

I'm running Castrol Syntec full synthetic in my 535is engine, 5W-50 weight.
Redline MTL in the tranny.
Redline 75W-90 gear oil in the LS diff.
My much older e9 has the same lubricants.

Red Line MTL in the gearbox, 75W-90 or 75W-90NS for the diff, you can get em at SummittRacing. Read the descriptions to see which you need. Lots of other places have em too, but at a buck a bottle difference is it really worth it to spend an hour figuring out where to order?

Since your location says Chicago, and I can't imagine it is warm there yet, you might want to try something before you put 20W50 oil in your car. Buy one quart, leave it outside on a cold night, then in the morning, see how thick it is when you pour it into something, and think about whether you want something like that in your car when you start it up in the morning.
I've run Castrol Syntec 5W50 in all my cars and my motorcycle for years.

Jim, that is a great suggestion for those who have not switched to synthetic oils yet.

Can anyone offer an opinion on Red Line MTL vs Red Line MT-90? MTL is 70w-80, and MT-90 is 75w-90. The descriptions on the bottles are identical. A call to the company only served to highlight the fact that that people who answer phones don't always know what they're talking about. Since I live in a warm climate, I'm inclined to use the MT-90.
