Subsequent checks reveled that Amoil Malaysia keeps stock of this product and I ordered 3 gallons to test it on my E34.My E34 has always had cooling problems having gone through 2 radiators, a few hoses and 3 water tanks in my 11 years of ownership. I also had a constant need to top up water every week as water keeps disappearing. I always suspected pressure had something to do with the water loss as well as exploding hoses and water containers. More reading also confirmed that BMWs keep the cooling system pressure higher than other makes. So when I read about Evans NPG+ which claimed that because their product has a boiling temperature much higher than water, hence it would not boil. (Not under normal operating conditions) So if the liquid don't boil, then it won't turn to steam and hence the pressure will be the same. Zero. No pressure means less stress on the hoses and plastic water containers and hence there won't be a chance of these exploding or rupturing. In theory anyway.So since the theory was sound, I decided to put it to test. First I got 3 gallons of Evans NPG+. Cost a bomb at RM250 per gallon. Then went to my usual mechanic to use his facilities to drain out all the water/coolant in the engine. This was done by removing the drain plug at the bottom of the radiator. Also removed all the water hoses and blew in compressed air into each one of them. This is apparently important as water contaminates the NPG+. After satisfying myself that there is no more water, all the hoses and plugs were installed back and the filling in begins.The product looks and smells like honey. One is tempted to taste it but there is a big warning saying this stuff is poisonous, blah blah blah. US product, so all warnings must be displayed. All in all I used a little over 2 gallons. Note that this is US gallons at 3.8 litres per gallon. Probably used about 9 litres total. At this point my mechanic who was skeptical from the start betted with me that if after going for a test drive and if we opened the radiator cap there was no usual violent rushing of steam he would pay me 50 bucks. The bet was on. So off I went for a few kms test drive. Nothing changed. Temperature is still at halfway mark. No improvement or anything unusual with the drive. Until I got back to the mechanic place and opened the bonnet. First thing I tested was to press the rubber hoses. Very hot but soft where previously it was hard. Feeling confident, I went and opened the cap and there was absolutely no drama. No pressure at all. I won my bet.So there. First impression is that it works as advertised. Absolutely no pressure at all. With this I hope the cooling system of my E34 525i will be less stressed and I won't ever have to suffer from blown hoses and ruptured plastic containers again. I will monitor for the next few days especially when I drive the car hard. And through KL traffic jams. About the only bad thing so far is the cost. But then again our radiators and stuff is not cheap as well.</blockquote>
