It's not that I needed any coolant as I always have the LS serviced at either the Lexus Dealership or the Toyota Dealership if I am here at home in NWA and they always top off all fluids. My 90 Ford Bronco II was low on Coolant and I was driving it to Tulsa yesterday to make a Costco run and was just curious if the 2 units used the same type of coolant. Now I know that they do not.

I would stick to the OEM fluid. Especially as the Toyota dealer usually sells the stuff for very close to what an aftermarket coolant would cost. Since it's in the vehicle so long, it makes the decision easier. I think here in Canada, I paid about 2 bucks more per jug than Zerex.
