Best antifreeze?

Anyone here use the Peak Fleet Charge antifreeze with SCA pre charged?
Seems like a decent price for the concentrate.
Thanks

I haven’t personally but folks around the forum have mentioned using it with good results.

Fleetguard Red Coolant

Good morning everyone, so I've been on and off searching multiple forums about using Fleetguard's red coolant in our engines. It comes pre-charged with SCA's and I can get it pretty cheap from work. The only answers I'm finding are pretty vauge, or people suggesting to use other coolants. So I...

I've used it in the past without issue. But recently (5 years ago) went with zerex G05 due to price. So far, no issues

Thanks Everyone for your responses.
Decided to go with the Peak in concentrate for the best price.
$20.09 a gallon, $1.40 gallon of distilled water = $21.55 every two gallons, and no need for the $20 additive.

Most diesel owners don't understand the need for routine coolant maintenance. In my view, cavitation is an old wives myth. Velocities in the cooling system are not high enough to cause true cavitation. What actually happens is that the true cause of corrosion of the block, oil cooler and older steel head gaskets is caused by the coolant becoming acidic. Diesel engine compression and brake mean effective pressure is so high that over time, CO2 molecules get by the head gasket into the coolant. Water plus CO2 forms carbonic acid and if the coolant is not treated to raise PH, internal cooling surfaces of the engine will corrode. Long haul diesel fleet operators have known this for a long time and monitor coolant chemistry, adding supplemental coolant treatment when needed. Here is good, inexpensive source of coolant test strips.
