Lets Talk Coolant
So, I have been checking into which kind of coolant would be acceptable to put into the RX. We all know that the stuff from the Toyota or Lexus dealer is fine, but is there an alternative? What if you are out on the road, and need to top off? It looks like you should stay away from, anything containing 2-EHA, because it eats silicone. This includes the Prestone 50/50 that is supposedly good to use in all vehicles. I'm not positive that Lexus uses silicon in any of its seals or gaskets, but if it does, it could be bad news. I also came across this article:

The Japanese see HOATs differently. Apparently, hard
water isn’t a big problem in Asia because Eastern car
manufacturers typically specify formulas containing
phosphates, but no silicates. Their extended-life green and
pink (Toyota) are based on OAT, mostly sebacate with other
inhibitors in smaller amounts (2-EHA is taboo, as we said)

Just had my 08 (90K miles) done before the Christmas's 2K miles trip.
2 gallon of Toyota Long Life at Amazon = $50, my mechanic charged labor $65. Total $115.
Pay a few bucks more on factory coolant, but one less thing to worry about.
