PineRidge : I use the Fleetrite with distilled water. First this is only what I have used when compared to some other coolants. Starting in 94 I used the Fleetrite in my gsxr1100 motorcycle. Then I used it in my truck (powerchoke) then my tractors and my cars.
I have noticed that the internal surfaces do not get the dropout from deposit. If you want it even better/best I use distilled fluid.
Junkman —not starting a war here but the extra $1.20 per gallon for coolant is not really extra cost. That is less then a small Dunkin Donuts coffee. Also the (1) gallon of distilled water is like $0.89 at Wal-mart. So the total added cost is about $1.99. Cheaper then a gallon of milk. I figure for the $16,000 for my
BX22 I can throw in an extra $2.00.
I know when I was a member of Ford diesel forums people on used these types of coolant. Even International and Mach recommend low –silicate coolant. The yellow prestone is high and it bad for diesel as they have stated.
I only change my coolants every 2 years and the rads are as clean as day #1. Open the cap and it is nice and clean. No junk. I can take a picture of my bike and the thing is unbelievably clean.
Not trying to make a boilerplate statement but rather going with the 1,000’s of people with the powerstroke, International and Mach use. Also I know John Deere makes a low- silicate anti-freeze just for this reason.
Art : Yup, the SCA are important nit some Fleetguard have them included in some coolants. In some engines, ie Powerstrokes, they forgot the sca's and had major problems.
