The early Dex had some issues. But this has been rectified for a good 20 years, so that's all I use. I'd like to give everyone this advice, which I learned the hard way. Unless you're all out racing, stay away from Evans coolant, ESPECIALLY if you're running an underdrive balancer! It's great stuff, but it's propylene glycol, which will run hotter than ethylene glycol, due to having poorer heat dissipation qualities, even though it does have a higher boiling point. I have no experience with their street formula, which wasn't out when I last used it. Another tip-Take the OEM advice seriously when they recommend changing ANY conventional anti freeze, including Dex, after 4-5 years, 5 at most!!! I never knew this, but as coolant ages, the PH changes, from a neutral value, to an acidic one! This means that as your coolant gets to be around 3-1/2-4 years old, it actually starts attacking the cooling system, as acid tends to do!!!! So it not only loses its lubricity properties, it actually tries to assassinate the radiator, heater core, and every component in the system. Hope this helps someone......

I didn't know about the strips. Sounds like swimming pool water testing!! Thanks for the info. I believe 7.4 is the correct balance for PH, but agree with you that 7.0 should be OK. An old friend of mine worked for many years in the oldest and biggest radiator repair/recoring shop in my part of the state. He told me the DexCool of the 90s, when left in too long, would coagulate into a Jell-O type substance, effectively bringing all flow, and cooling, to a stop.
