Hi all - I have an 02 Targa, and I'm getting ready to swap the fluids in the car to set a baseline, as I don't have much history as to how old what's in the car is. I'm headed to my first track event in this car in May 6th, so I'm looking to do these over the next couple weekends. I'm looking for recommendations on what to use for:

Trans fluid
Brake fluid
Clutch fluid
Coolant

Thanks in advance!

My reco: Ate tye 200 for the brake fluid (the clutch shares the same brake fluid). The rest Porsche genuine fluid from Sunset Porsche parts.

I used all Motul fluids for mine including:

Motul Race brake fluid,
Motul Coolant
Motul Transmision fluid
Motul 8100 Excess Oil

Car feels great.

From a specification perspective Motul 600 brake fluid looks better than ATE 200 for about the same price.

Ahsai

That is correct. However, if you use Motul 600, you need to change it out a lot more frequently than OE type of fluid.

Motul 600 is a higher temp fluid, about double the price of ATE 200.
ATE 200 is a 1 liter can and Motul 600 is 1/2 liter. Still not that much more $ for better performance

Motul will also absorb moisture faster than ATE 200
Not a big problem, just flush and fill every year instead of every 2 years

In any case if you are tracking your car at minimum flush and fill every year and bleed before every event

Lets not get into an oil war, but Motul 8100 Xcess is a much better oil than Mobil1. Not that much more $. You can get 20 liters on Amazon for around $135 that comes out to around $6.43 a quart (sold in liters not quarts) vs ~$5.20 a quart for M1 at Walmart, so around $11 more for an oil change
It has a higher temp sheer and if you are tracking, you engine get much hotter

+1 for Motul

Distilled water will work for all of those.*


*By "work," I mean "will displace air in the respective tanks/reservoirs."

Easiest way to replace the brake fluid is to use a turkey baster and replace the fluid in the reservoir. Do this 3 times over 3 months and all the fluid will be replaced without cracking the bleeder screw open.

Auto or manual trans? I have an LSD, so when i choose to replace my trans oil, I plan to use the Porsche recommended Porsche brand fluid, since the manual trans and differential uses the same oil. LSD depends on the proper fluid type. There are alternatives, but again, I'm spending the money on the Porsche fluid.

How does this address any water that has diluted the fluid in the brake and clutch lines?

JayG

Nope, nada, ain't going to work

drinking bagged milk must have affected your brain LOL

IMO's method works ok for power steering fluid but I wouldn't try it with brake fluid.

For a manual tranny the Motul Gear 300 works really nice.

JayG

That makes sense. IIRC, power steering fluid is circulated while brake fluid is not
Feel free to correct me if I am incorrect

Imo000

Brake fluid circulates too due to convection but at a very slow rate. That's why the fluid gets dirty in the reservoir, otherwise the fluid would always stay clean in the reservoir and only get dirty in the lines near the calipers.
