First what engine oil brand do you all use for the s2k and I also bought a Lucas Heavy Duty Oil Stabilizer. Will that help my engine to worked better?

Second I bought a Redline 75w-90 trans oil for my s2000 but just in case I will like to ask u all if this trans oil will be good for my S2k. If not tell me what kind of brand u all use. I love my car soo much so I want 2 give it only the best. Also I am new to this s2k forum and I will be seeing u all in future meet ups. Thanks 4 da help.

Engine: Use any Brand Name API Rated 10W-30....5W40 can be used. 10W30 is prefered in North America. I use Amsoil 10W30.

DO NOT USE ANY ADDITIVES AS ITS NOT RECCOMENDED BY HONDA.
Return the Oil Stabilizer and get your money back.

Transmission: If your transmission is shifting fine, only use Honda MTF.
75W90 is not the right fluid for the S2000 Tranny. If you want to use synthetic, try Amsoil Synchomech...its compatable with Honda MTF fluid.

Syncmaster

I use Mobil 1 10w30 full synthetic for the motor and Honda MTF for the tranny. I also have been using Mobil 1 75w90 synthetic gear oil for the diff.

Engine: Chevron Supreme 10W-30
Tranny: Redline MTL
Diff: LE-607

I think I read in the Under the Hood forums that Redline does not hold up well over time in the transmission and that Honda doesn't have an official MTF for the S...maybe Amsoil makes a tranny fluid that is better, and a lot of people use GM syncromesh tranny fluid... I'd read some threads in UTH and see what people have to say.

This thread will help a lot - https://www.s2ki.com/forums/index.php?showtopic=195574

There are a series of oil journals written by RoadRage that are excellent.

The info that has been given here is a good summary though.

Engine 10w-30, most people run a synthetic. It is suggested that synthetic is not run in a new engine, you switch over from mineral oil to synthetic after 7k or so. I personally run Mobil 1 10w-30.

Tranny, people seem to sway between the Honda MTF and the Syncromesh. I'm running the Syncromesh right now and it's fine but I never had any problems with the Honda MTF.

The diff fluid is what most S owners are the most passionate about. Running the LE fluid is highly recommended.

after 10k miles i went to royal purple... but have switched to mobil 1 (also synthetic) now-
prob more important than that is the fumoto valve that i installed after my break in oil was changed...
and agree that you should check out the oil journals on this board

I think you've got your "casings" mixed up. Redline "Shockproof" doesn't last very long in the rear diff and Honda car division doesn't make an "inhouse" fluid for the diff. Honda MTF is perfectly fine for the transmission.
And yes, do look at the "Oil Journals" for an indepth accounting of all things oil.
