[QUOTE="Iso-baric, post: 1563222, member: 32327"] Both CAT ELC and ELI (same additive pack - glycol free) are NOAT coolants and compatible with aluminum. No issues mixing NOAT & OAT coolants, you just diminish the additional cavitation protection nitrites provide. I've always abided by the rule that you can use a NOAT/OAT coolant in place of a HOAT/IAT, but not the other way around. Definitely do not mix NOAT / OAT coolants with HOAT or IAT as this is when you will run into issues with silicates coming out of suspension and sludge forming.
