Has any one used or have any thoughts on using RV / Marine anti freeze in there dragster. I know it's warming up now but once I fill the system I don't want to have to drain it and winterize. The thought is that the RV anti-freeze is 1. It's not toxic and 2. If you have a leak or blow a hose it's not oily like auto ant-freeze so it won't cause an oil like clean up on the track.

NHRA wont even allow Water Wetter which is a product used to lubricate the cooling system. They want nothing but water in the cooling system.

What they want and what they get are two different things.

I was busted for having water wetter in my car at a race in Indy a few years ago. Made me drain and flush the system and had to get a tech guy check it before they would let me run again.

I did a little research on the RV antifreeze. Its primary ingredients are Water, Ethyl Alcohol and Propylene Glycol. Whats interesting is that the Propylene Glycol is approved by the FDA as a preservative in food and tobacco, was also used as an oil dispersant for the Gulf oil spill and deicing of planes. The only ting I have not been able to figure out is the heat transference coefficient. Might be worth a call.

No way I run straight water in my car. Sorry NHRA!

No way I run straight water in my car. Sorry NHRA! Mine sits out to much at the track. Not to mention we race from late feb to late thanksgiving. My car was completely covered with frost / ice at the t-day race this year

Don't know about the heat transference coefficient but we have used the RV antifreeze in the past. Didn't have any cooling problems. That said though we are on alcohol and except for when hot lapping we are normally trying to build heat. Scott

An inherent problem with RV anti-freeze in a cooling system would be its tendency to foam when mixed with water and agitated - like in a high flow pump. Foaming is not good when you're looking for heat transfer. I own a DP Motor coach and have used it. When cleaning out the system it takes forever for the faucets to stop "fizzing". It is intended to be used full strength and when mixed with water does not provide near the corrosion protection of WW or automotive anti-freeze. I would personally never use the stuff in my RC for that very reason. Stick with WW...don't drink the pink "Kool-aid" (even though you could).

Interesting about the foaming. We used it 100% and didn't notice any foaming or cooling issues.
Just thinking here... It doesn't matter to me what a person uses for a coolant and not trying to argue but from a technical standpoint can something foam up it its in a closed system and under pressure? Is the foam you seen happening when it went from a closed system to the atmosphere at the faucet?

Scott Good point, Scott Yes, the foaming was when it was coming out of the faucet, but for some reason, only after it started to mix with water. Full strength it seems more stable. It does provide good corrosion protection , but again, full strength. Mixed with water it rapidly losses its freeze and corrosion protection capabilities. But...to each his own. If you have used it before successfully, great. I think a hard-assed tech inspector will still make you dump it, even though it cleans up easier than ethylene glycol. I'm not sayin' whats in my car -oh, what the hell...it's Jack, neat. Just in case I need to bribe the tech inspector..

Probably so. We don't use it currently. Don't want to fight the battle with a tech inspector plus its easier to just use water.
