Evans NPG + Coolant Review
I have a 2001 Audi S4. These things are fairly sensitive to heat, what with a 9.3:1 CR, two turbos and a very cramped engine compartment. I got tired of having to baby this car in the Florida sweltering heat. After I flushed the G12 outta the system and made sure there was no water left (kind of a pain to convert but you only have to do it once,) I put two gallons of Evans coolant in with a gallon on the shelf since you cannot mix this with anything else. My temp gauges behaved much better and my oil temps even went down slightly.
Between the Evans coolant and the Redline oil(Amsoil has worked well for me too), I averaged 25mpg (mainly highway with stints of fun when I could.) This is in a car rated for 21 to 24mpg. Plus, during my commute of 43 miles each way, I could run 89 Octane instead of the required 91 for a turbo car. Those mid grade tanks of gas got me ~26mpg average but after the first few stints to redline with full boost it would start to knock, so 89 only for commuting.
With a tank of 93 in, I could rev and boost all day in the Florida heat and then sit in traffic with only a slight indicated increase in water and oil temps. I had to shut down the car or sit and hold the engine at ~2500rpm before. I was also able to do back to back runs at the local drag strip with no problem (Not so for a friends very nice modded STi. Its coolant system blew up mid track after about the 4th pass.)
The only reason I didn't give it five stars is because when you get a leak (and if you own an Audi, it WILL leak.) /gal is pricey. No leaks, no problem, its 5 stars worth it then. It has been three years now and I am in Michigan enjoying their winters with the original coolant and still no problem. Also, Hoerr Racing is an awesome place to buy this stuff. They are fast and reasonably priced.
