Evans waterless engine coolant
Any opinions or experiences would be appreciated.
Cheers, Colin
There is good money in fuel, oil, coolant, battery, and tire additives...they've been selling them since cars were invented.
Your engine, by the way, couldn't care less...






The $$$ vs benefit seems pretty steep to me.
Good distilled water and antifreeze seems much more affordable should some leak or get lost during draining and replacement of hoses or anything else to do with the cooling system.
Google it, do your homework it's got a lot of cons including price and hassles and no real pros in a normal street car with a properly functioning cooling system, it doesn't cool any better than good old pre mix in fact even stated by the company the engine very well might run hotter...this I would never pay anything for much less their high prices.
For me in fl I dont need anti freeze but additives for the metal and water pump I will run water and a product like....

But if you think the only cars that cool correctly run evans then by all means run it....

It's not touted to cure an overheating problem. It's a lifetime coolant so everyone replacing their coolant and doing flushes will spend much more in labor and replacing coolant in the long run.
Dissimilar metals in contact with water will generate a voltage which results in corrosion. If you have spent a lot of money on your engine, and you would like to reduce maintenance costs, you should use Evans particularly if you plan on keeping the vehicle a long time.
When you change hoses, thermostats etc. just save the coolant in a clean bucket and reuse it.
There is some evidence performance is increased by using Evans due to more even combustion temperatures.

Evans is polypropylene glycol with some additives...hopefully such as water pump bearing sealants. The big, and only advantage I know, of polypropylene is that it's not poisonous. Both polypropylene glycol and ethylene glycol have very nice sweet tastes. Drink ethylene and you'll die a slow and very painful death due to complete liver failure. Drink polypropylene and there'll no harm...look at candy bars and "healthbars"...they often contain polypropylene. Polypropylene is not poisonous. I've read that Switzerland mandates polypropylene in automobiles...ethylene is illegal. The danger of ethylene is that it will kill curious small children and dogs that drink it. Poly is expensive...$50+ a quart? Ethylene is ~$14 a quart.
Both of the above 2 coolants, will prevent rust in your block, heads, and radiator. Neither coolant will boil below ~350 degrees F. This means you coolant system is never pressurized! (Note; all the water must be gone.)
All the WWII US and English fighter planes used 100% ethylene glycol in their Merlin, Griffin,Allyson V-12 internal combustion engines.

Evans is currently a mix of propylene glycol and ethylene glycol and is rated low toxicity. Technically one usually dies from kidney failure due to the formation of calcium oxalate crystals in the kidneys.
I personally wouldn't use straight ethylene glycol in an engine as its formulated to be mixed with water. Evans is specifically formulated to be used without water. They've done the research, but as you say straight ethylene glycol has been used before but I don't know enough about it.
