Fluids!

[Goku]

OK being lazy as I am, I thought I'd just start another thread on this. I'm in the mood to change all my fluids. Its about time anyways, car is about 70k and sees race conditions about 3-5 times a month. Other wise its in the garage 99% of the time.

Heres what I'm looking to do.

Radiator fluid. I want the best cooling possible. What should I use. Please provide a link if possible, or a known auto parts store that carries it.

Trany Fluid. Once again I want some top notch stuff. Please provide a link if possible, or a known auto parts store that carries it.

Diff Fluid. I want some stuff that can take heat, I'm OK with it if its like honey when its cold, and car is a bit difficult to drive. Same thing please provide a link or know auto parts store.

Thanks guys. I'm looking for race prov-en stuff here. Let me know what you run.

but when i had OEM i thought it felt smoother. I change it every 10,000 miles.

Here is the OEM stuff (new formula).

Lubrication Engineers has a new product for the Differential - LE1605, sold by Ricks'

Either that or you can get a GL-5 rated fluid from an auto parts store such as Mobil1 75-90w. It is repiv approved. The diff whine that it makes is normal he says. This is what I have in.

Go with the new formula MTF fluid for the transmission. It shifts great!

Oh, and if you need any other maintenance parts for the s2000, they are here

hey
I'm changing all my fluids too
ive done a lot of extensive research and came up with the following

Royal Purple or Mobil 1 synthetic 10w30 : engine oil
GM Synchromesh Friction Modified : tranny
Motul 600 : brakes and clutch
Mobil 1 75w90 GL-5 synthetic : differential

there are more expensive fluids out there that are used for a slight advantage in terms of performance, but they'll require changes more often, and i really think they are pointless unless your car is 110% track.
the fluids i listed above are NOT the most ecnomical though, I only want the best for my s2k since I drive it hard. But I'm sure your willing to spend a little extra for your baby :)

Disclaimer: Most of my observations are based on the reviews and experience of long time s2k "techies" :O

This is whats in my car, I don't autoX like you Boyd, but these seem to work fairly well.

Engine: Mobil 1 10w30, every 3K
Trans: Honda MTF, every 10K
Diff: Mobil 1 75W90 GL-5, every 10K
Brake: Honda Brake Fluid, once a year
Coolant: Honda type 2, every 30K

[smac2K]

Diff: Mobil 1 75W90 GL-5, every 10K

EVERY 10K!!! :yikes:

I should probably change mine then...:lol:

[spa01s2k]

Diff: Mobil 1 75W90 GL-5, every 10K

Takes less than a quart and is very easy to do.

[smac2K]

So, just how do I do this? I bet there is a DIY thread somewhere....:sprint:

Gonna go look...

[kwando]

every 10k mile = butter shifting

You can't go wrong with these. If you track the car, more frequent changes is a good idea. Tracking a car is far worse than the conditions stated for "severe" service.
A higher temp brake fluid might be a good idea for a tracked car, however, higher temp brake fluid sucks up water faster than lower temp fluid and thus, require changing more often. A regular street driven car on "normal" brake fluid can go 2 to 3 years. High temp brake fluid should be changed seasonally (before and after the track season) and more often if the limit of brake fade is reached often.

A daily driven street car can likely go 20K miles or more, but changing the diff fluid is such a cheap and easy thing to do, it can be done annually for insurance. If you drive the car hard or track it, change it seasonally. We have a tiny rear diff with a small amount of fluid for the kind of power and stress that gets put through it. The fluid works hard to both lubricate and to cool the diff. Heat may be the worst enemy to our diffs. If you track the car, a thicker fluid may be in order. Something like the new LE formula or a 75W140 GL-5 fluid.

As usual, Thank You Dave! I will try to do this VERY soon! Hopefully before the drive this weekend. I can tell she's gettin sluggish, and definately a difference in the shifting. :yep:

:thumbsup:

Sorry we hi-jacked your thread (kinda) Boyd!

[Goku]

nope all is good. Thanks for the advice Dave. I'm gonna run the new honda MTF, moble 1 75w140 diff fluid, and I'm still unsure as to what to do with the radiator fluid. Is there something better than just oem with water wetter?

Although new rear diff fluid will make shifting a bit better, it's the tranny fluid that will have the most affect on the shifting quality.

A 2002 car has Type II coolant. Supposedly, this is good for 10 years, however, I would never trust a coolant for that long. At the very least, it should be tested after 5 years for freeze point and boiling point. There is a thread currently that talks about water wetter. "Hecash" uses it and he tracks his car a lot. His advice in this area would be golden.
Unless you are experiencing abnormally high running temps (like 4 bars or more), stick with the OEM coolant. If you are getting high temps, read that water wetter thread and consider some cooling mods (lower temp thermostat, fan switch, rad cap, bigger rad) and have the water pump checked.

I am not having any cooling problems, but i just want the car to be able to run as efficently as possible. Since I Auto X I can't mod my cooling system just yet. I will wait till I get suspension and a few other goodies. I just want to know that what I have in the car will keep it as cool as possible.

EDITED BECAUSE DAVO MADE FUN OF ME...

[Goku]

Just got the new Honda MTF and Type II coolant yesterday. Need to go down and pick up some moble 1 75w 140 from the auto parts store. Does any know where you can buy Water wetter locally in Denver?

[kwando]

autoparts store should have them. if not i have one that i have not used that i will sell you.

[Goku]

Anyone know the mix I should use with the type II coolant and water wetter?
