I'm going all redline fluids, just for the hek of it.

Did it get these numbers right?

10w30 synthetic oil
6 quarts
8.99 a quart
53.96

MTL trans fluid
2 quarts
8.99 each
17.98

75w90 diff fluid. Is this what I need? What's lightweight shockproof gear oil?
2 quarts
8.99 each
17.98

Total Cost: 89.92 before tax

Thanks for the help

Yep that the right numbers, except I think the diff only takes one QT. And you might want to have 1 QT. xtra motor oil. unless you dont burn much. Also MTL may be a little light for the s2k, IIRC

tcjensen

so 75w90 is the right stuff for the diff?

would you recommend mt90 instead of mtl for the trans?

oakfloor

I would use the LE607 in the diff. I had MT-90 in my tranny and it was notchy untill warmed up. I like the gm oil the best so far. MT-90 would be good for your texas summers, as would the 607. Or for tack days. RL 75-90 will work in the diff, to be sure, look up there web site.

Ok. I did some searching.

Definitely not using the shockproof stuff.

Sticking with the MTL through these colder months, then will switch to MT90 in the spring.

Going with

10w30 synth oil-7 qts
MTL trans fluid-2 qts
75w90 gear oil-2 qts

Thx for the input! Bout 100.00

MTL is the correct fluid to use in the transmission, it matches Honda MTF viscosity perfectly. I'm using it and love it. If you for some reason truely feel that the MTL is too thin then try a blend of MTL/MT-90 before switching to straight MT-90.

The rear diff only takes ~.8/quart so you don't need to buy two bottles. LE-607 is the best choice for your rear diff unless you drive the car in temps that dip below the 30's. If you drive your car in all seasons (and have cold winters, which I bet TX doesn't), then Mobil 1 75W-90 or Redline 75W-90 will do the trick.

Mixing oils - while not necessarily a "bad" thing - is not a good idea either. According to some of the info I've read in the Oil Journals, and from talking with Amsoil tech service in the past, there's a possibility you'll actually reduce the life of the fluid by mixing it - and mixing higher and lower viscosity oils does not make a "medium" viscosity oil - they don't mix in solution (it's kind of like mixing basket balls and ping-pong balls - they don't make volley balls).
The reduced life can be caused by the interaction of the different detergent packages in the oils. Most oils aren't meant to be mixed.

you only need 5 quarts of oil just fyi...

Not saying you're wrong, but I have not seen Road Rage (the dean of the oil journals) say this. Did I miss it?

To the OP, from a big fan of Red Line:

1. Good job not falling for the "I use Mobil 1, and I've never had a problem" line -- Red Line's just better oil.

2. 10-30 is your best choice in TX, but Northerners will need 5-30 in winter.

3. I have Red Line in my diff right now, but after doing a lot of research I've concluded that LE-607 really is better.

4. Try the MTL in the transmission, but understand that transmissions seem to vary in their preferences for some bizarre, inexplicable reason. If your shifting is notchy, try something else, either the new Honda fluid or the GM Synchromesh FM. Or Amsoil, I suppose. Don't be such a purist that you stick yourself with what could be, for you, an inferior product.
