Best possible fluids, oils, and liquids?

Maybe asked before, prolly not in the same post.

Please list your favorite oils, coolants, fluids, and etc. For all possible applications. Brand names, weights, amounts, and all that good stuff.

Motor oil - Mobil1, if money was no object I'd go Redline
Trans - Redline MT-90
Rear end diff - Redline 75W90
Brake/clutch fluid - Ford Hi-Performance, if money were no object Castrol SRF
Coolant - Prestone (although a recent story on Mercedes coolant got me thinking)
Grease - Redline CV-2
Penetrant - Liquid Wrench
Anti-sieze - Permatex nickle
RTV - Permatex Copper RTV
(no windshield washer fluid)
Pre-mix - Valvoline Multi-use Premix, if money were no object Redline premix
Non-toxic cleaner - Oil Eater
Drink - ANYTHING fruit punch

That list might have some expensive fluids on it, but how often are some of them changed? Initial out of pocket expense might be high, but spread the cost over time and it isn't so bad. Can't go wrong with Ted's list.

redline motor oil is actually just repackaged from a major oil company. Shhhh, you didnt hear that from me. ; )

for me, i used valvoline 20w50 in the engine. And believe me, for as much money as i have into the motor, this is what i use. They real key is changing it frequently.

I used motul brake fluid, but it does need to bled often. It obsorbs water easier. The ford stuff i hear is pretty good.

Coolant, use the green stuff. I just use the mazda brand coolant. (Prestone)

Tranny: Redline MT-90

Diff: Redline shockproof gear oil

Drink: Long Island Ice Tea (best bang for the buck)

Don't worry about it. Just use Mobil1 or the good ol' Castrol GTX and change it often.

I would say:

Motor Oil - Royal Purple 10w40
Rear Diff - Redline 75W90
Tranny - Redline MT90
Coolant - Evans Non-aqueous coolant

that's my plan, anyways.

Sure, that'll work.&nbsp It's the same thing as Super 200, but with a blue dye in it.&nbsp Lots of racers switch between the Super 200 and Super Blue just so they know when their ENTIRE brake system is flushed.

This still won't touch the Castrol SRF. Castrol SRF is da **** when it comes to brake fluids. &nbsp You ever priced this stuff?

Ya thats good to hear. I ask because this performance shop nearby recently switched from redline products to royal purple. Its more convenience than anything really

Use the rain-ex washer fluid. It's very JDM. Plus, if it snows, it looks like someone peed on your hood.

Valvoline 20w-50 in the motor, redline everywhere else.

My car has the following:

Motor: Castrol GTX 20/50 summer and 10/30 winter
Trans: BG syncroshift
Rear: Redline 75W90
Brake: ATE Super Blue

I was never particular about brands of coolant in the car...if it's green and you mix it properly (or buy the pre-mixed) I wouldn't worry about it. I think some of the more expensive brands have less/no silicates which can corrode rubber hoses and water pump seals over time.

well i just changed the tranny fluid and diff fluild with 75w-90 Valvoline Synthetic and is shiftes great now, but i'm still going to change it to Neo Synthetics 80w-90.
For the coolant, what me and my friend's run in the summer is the following: 30% coolant, 70% water, 2 drops of Plamolive (dish soap). The plamolive breaks the surface tension of the water (same thing water wetter does) so that you get better heat transfer. Durring the winter i think it's just best to run a 50% 50% mix

edit: oh and brake fluid will be Neo Synthetics becasue it costs less then Motul and has a higher boiling point
