Coolant and yes I have searched and read

Just use Porsche coolant and you don't have to worry about all this BS

Or Flush it and run green on all your cars. Makes it easy and inexpensive.

ChrisFix has a really good video on how to flush cars.

Typical Forum response.

In 1989 Nissan made the SR20det Alloy engine, cast and turbocharged. It has 27 years of life and its only headgasket failure was caused by lean mixture causing high temperatures. That engine has seen race track temperatures for the last 10 years with 50% prestone 50% de-ionized water.

Our 17 year old porsches are not different. Ok maybe better looking and as good balance. What they don't require is magical coolant. They just require water that doesn't cause galvanic corrosion.

Also what is the point of long life coolant? Thermostats & water pump both fail way before the 5 year mark if the car is actually used and not stored. 5 Gallons of fluids with that 50/50 combo will set you back 40$ and you actually have 6 gallons of that stuff. That way you can give what it really needs! Good oil.

But that is my constructive criticism built from a decade of finding the best way to maintain a car without breaking the bank.

These porsche cars actually do!

Quick question; what is the cast AL type of your engine case/heads? the composites used for the gaskets, tank, fittings, hoses, what are their chemical compositions? Do you know?

Take your trusty Porsche Eng's advice when he says you should use, and only use, Porsche approved fluids my friend. (No-No Wallmart weekly specials allowed loll)

Besides... all of the extra profits they make while robbing you with their great TM does in fact back right into R&D. Meaning better cars for our next generations (or silly EV cars, whatever). Support the Brand!!!

Well if they sold in the USA they had to follow the SAE standard. J814: Engine Coolants - SAE International

Al, they are all corrosion resistant: Aluminum VS. Copper-Brass Radiator: Corrosion Susceptibility
Headgaskets usually steel ring is touching coolant.
Hoses follow a standard. For example a different hose J30R6 for fuel.
Tanks, plastic most likely ABS.
Fittings if they are not steel or cast allow or ABS

Walmart is just a retailer, you could by the same thing at CaCanTire if you want.

All that the OP needs to know is that both fluids are not compatible. They will all provide the protection needed at different costs.

Its all about good-feeding-anything to your car really!

Personally if there would be anything more expansive than the Porsche Pink, I'd just buy the more expansive stuff... given its on the list of approved by P.

Just feels right LOL

Coolant flush, feel fresh; the rest is to wear your newest pair of sport shoes, and go for a proud roadster ride somewhere downtown... where everybody can't see you new shoes, and over-priced coolant.

It just alllllll feels right. Consistent with the brand, you see

(ps: leaving the blah blah blah tech behind!)
