What type of Anti Freeze is the best to use?

I don't believe that an antifreeze would lower the temp by 20%, even if the WaterWetter advert says so.

It is correct to say that an antifreeze liquid, when properly diluted according to the manufacturer's instructions, achieves a higher boiling point of 10% and more, if compared to common water .
So, it is obvious that it is helpful even if it is used in hot weather situations, when the engine tends to heat too much.

All the antifreeze types are similar each other, try to choose a reliable brand.

I´m presently investigating "waterless" engine coolants. I hadn´t heard about them until very recently.
Kind regards,

I've used water wetter in a couple of cars, usually with straight water to obtain the best efficiency. You can't do that practically with a street car though. I experienced zero effects. Your mileage may vary.

 

Some people swear by Evans coolant from Australia. Have a look.

 

staatsof,
interesting ...but very "straggly" reading.
could you point us in the direction a summery of conclusions against the product?
mr Leno is strongly endorsing the product I have seen.
kind regards,

I run common antifreeze made for use in aluminum engines but you MUST use distilled water if it needs to be diluted, never run tap water. If it still over heats you have other problems.

 

Against Evans?

I have never used any waterless coolant so I've nothing to say about it.

Typical antifreeze breaks down especially when left to sit. Change it regularly and you should be fine.

 

Evans Coolant is a US based company. They have a website that gives all the relevant information on their product. One thing to be careful about is the total removal of all possible water in engine and cooling system or you will have problems. Evans is well known and has been around for quite a while and has a good reputation.

Generally speaking, if the car was made before 1993, use only Conventional Antifreeze. Cars built after 1993 should stay with the Long-Life coolants. Inspite of what the antifreeze manufacturers state, the two DO NOT mix well, and switching an older car to Long-Life will eventually cause problems. We use a product called No-Rosion in both the street and race cars. They have a website that tells all about the various coolants, and explains the plusses and minuses. The company's main products are for water anti-corrosion protection in industry, so they are not snake-oil. The straight scoop is there as they do not have an axe to grind with either type of antifreeze. We use No-Rosion in the race cars, as the sanctioning bodies do not allow antifreeze for safety factors as it is so slick if spilled on the race track. This way we can use water without any concerns about aluminum corrosion. The product also extends the life of conventional antifreeze from two to five years.
