Antifreeze Prestone or VALVOLINE

I just use prestone, it's green coolant. It's universal for all fuel types and coolant systems. I have never had any issues in the many years I have been using it.

I personally prefer OEM, but I was at a Lexus dealership for 9 years that used Valvoline and never seen it cause an issue

Flush your cooling system and replace the green coolant with Valvoline Zerex G48, it's what's inside BMW's coolant jugs at the dealer.

My mechanic just switched my antifreeze to “Prestone yellow”. He said it’s for cars with high mileage (150k and higher) he said it’s softer on our old hoses and such! Car is running great.

I used Valvoline Zerex Asian Blue Vehicle Antifreeze/Coolant in my 1st gen anytime I needed to drain the radiator because you can buy it anywhere. 50/50 is handy for top offs but if I was doing a full flush I got concentrated and mixed with distilled water which comes out a good bit cheaper.

Since that 5/2023 bulletin refers to Valvoline as formulating the latest version of G12Evo, and Valvoline/Zerex HT-12 says on the bottle that it is for G12Evo applications as well as referencing VW TL 774-L, it should be okay to use HT-12 in our coolant systems.

I've only ever used Prestone which works great and has never been an issue.

I use Valvoline's Zerex Asian Blue prediluted, it works just as well.

Prestone does work, but Toyota uses RTV to seal the coolant passages between timing cover/thermostat housing and engine block. Prestone uses 2-EHA which has been shown to be aggressive on silicone, however it’s not uncommon to see leaks with the OE coolant that uses sebacic acid which is also a plasticizer. That said, I have a Sienna and LS430 that’s filled with Prestone, no coolant leaks… yet.

Do not use Prestone 50/50. It is technically compatible, but it is a different formulation. Using Prestone 50/50 will shorten your service intervals to 36,000 miles. Beyond 36,000 miles you will cause damage to occur to the seals.
