Was looking through Rotary Tarts site, and saw "PURPLE ICE", which is supposed to drop the coolant temp "significantly".
I\'ve done a search, and not really seen any comments about this.
So......
1) does anyone actually use this stuff
2) and does it do anything (i.e does anyone have any real world data, rather than manufacturers claims?)
Was going to change my coolant soon, and was wandering whether £15 extra is actually worth the cost?
Cheers,
Andrew
Hi Andrew,
We have used coolant additives on some race engines and yes they do seem to work.They have dropped the temp as much as 10 degrees C.
They work by reducing the surface tension of the coolant and also reducing cavitation at certain rpm.

Thanks for the reply.
Maybe an unfair question, but would they be worth using in normal road cars, or only really worth the investment on a tuned track day monster?!
prob not fair for me to comment, but as rotarys run so hot even a couple of degrees over 60-80k miles must make some difference, if used once, probably a waste of time.
i\'m using said RP goodies & it\'s hard to give any totally reliable figures as it\'s never going to be a 100% like for like comparison but it does seem to have reduced water temps a bit so i have no issues saying go for it:cool as above even if it is negligable it sure aint going to hurt & far from an expensive addition...

Prolly -more- use for fast road - you don\'t always get a chance to do a cooling lap on the road, specially B-roads with short stretches of 30mph on \'em, and you don\'t tend to stress 5th gear for long periods on track either, whereas you might perhaps do that on long straight motorways with lots of hills in certain parts of Oxfordshire ;)
