Since this has moved toward a discussion of RP's products I will toss in some anecdotal "evidence". Because in part I got caught up in the gushing reviews, and because I could get it at the wholesale price, I had (at 30k miles) used RP's Synchromax to replace the stock juice in my '03 3650.
I used it again at 65k (once again I had a wholesale cost source), but when we did the clutch a month or so ago I could no longer get it at cost and used Mobil 1 ATF, and guess what--it shifts quite noticeably smoother, to the point that the little "hitch" between 1st and the neutral gate is almost gone.
Which gets me to something I have asked people for years, "Who do you thing has and spends more money for R&D? Mobil or Royal Purple (Amsoil/Redline/etc)?"

The thermostat maintains the engine temperature at it's (the thermostat's) nominal rating; that's it's primary function. It opens or closes--more or less, not completely--to keep the temperature within it's rated range. There is nothing that any additive to the coolant could possibly do to change that.
A "good" temperature is whatever the manufacturer decided it should be, for our cars 210°F is "normal", 180° would be cold and require retuning.
The "guy you know" is a dick, stop listening to him and start reading some decent books about internal combustion engines--Heywood's Internal Combustion Engine Fundamentals is the "bible"...

[QUOTE=Evenexchange;7056340]Sorry I was in the Maldivian islands last week. But thank you guys, I seriously ALMOST wasted my money on that stuff. I was actually on the verge of buying quite a few RP products.[/QUOTE]
With all due respect I think you are full of s***

[QUOTE=SonicMustang143;7056345]Lol, you think I bought it? I didn't. Well, I had it in my cart online before I left the country maybe hoping i'd have it for when I came home, but you all are pretty knowledgable so... why waste 100 dollars for something that doesn't work as advertised.
