What brand of coolant do you use?

[Matz]

I run 30% Prestone, 70% distilled water. The chemistry behind how I came up with that exact formulation is a little complicated, so I won't try to explain it here.

sorry to get off subject, but when are you suppose to change coolant?(mileage)
thanks

do a search, this has been discussed many times.

I use AMS long life coolant which is enviro friendly and can be flushed down the drain

redline water wetter is good but has no corrosion protection so it must be changed at least every year - better every 6mo

Link to AMS coolant?

IS AMS short for AMSoil?

Water Wetter can actually start attacking our iron block if left in too long.

Do you guys add anything else like Prestone water pump lubricant or something else?

When you start seeing iron flakes in your overflow bottle.

Like a year? Six months? Just seriously curious.
