To more or less corroberate Ken's results, I bought two quarts from the case he purchased last year, and used this stuff in my freshly rebuilt engine. I have a new 190 degree thermostat, new wiring harness, new temperature sender and NOS temp gauge, stock narrow width Mk3 radiator and stock mechanical fan. In other words, bone stock cooling setup and new instruments so I trust the readings I'm receiving are accurate. In all temperature conditions thus far, including 90-95 degree ambient temps, the temperature has never risen above just over the halfway mark on the gauge, even during extended periods at idle, and the overflow bottle has never come into play. Even when I turn the engine off, the temperature doesn't rise past the upper normal range on the gauge. For hot weather climates, this stuff seems to be ideal. I'm sold.

A 10:1 mixture of distilled water and Zerex Racing Super Coolant does a better job of cooling than a normal 50-50 mix of anti-freeze and water. With the antifreeze / water mix, in outside temps of 85-90 degrees F, the temp gauge would hover around the 3/4 mark. If stopped in traffic for say, 5 minutes or more, the gauge would head towards the H mark (hot, hot, hot). With the water / RSC mixture, same outdoor temps, normal driving - just shy of the 1/2 mark, idling in traffic - between 1/2 and 3/4 marks. Impressive. Unfortunately, RSC does not provide protection below freezing, so it is limited. But here in the almost desert climate of San Diego, no problem. It may now be called Valvoline RSC, can't seem to find it under the Zerex listing. And you have to buy a case of 6 quarts. At 1/2 quart per filling and changing it every 2 years, that will last 24 years !! :-) Good luck, Ken C /// [EMAIL PROTECTED] mailing list /// Send admin requests to [EMAIL PROTECTED] /// or try http://www.team.net/cgi-bin/majorcool /// Archives at http://www.team.net/archive /// Send list postings to [EMAIL PROTECTED] /// Edit your replies!
