I recently started looking at NPG+ non-aqueous coolant from Evans for my 1998 SE after reading about it in various Hemmings publications. My hubby is not convinced (he saw the price per gallon...). The car has 118,000 miles, runs well, and still pulls down great mileage, and I want to keep it that way--synthetic oil, regular maintenance, and maybe this Evans coolant. This car does the reverse snowbird routine--summer in the 100 degree plus desert and winter in the -20 degree north. Has anyone on the list used Evans NPG series coolants? How is the Evans coolant working for you in your particular climate? JD in the southwest summer desert
