I will NEVER EVER use that crap again, EVER! I put it in 2 different engines I built(one of them a brand new short block 350 chevy, the other a 4.0L JEEP) and both of them lost head gaskets within 2 years due to rust around the metal sealing rings in the combustion chamber area. Switched back to ZEREX now from NAPA and is the ONLY brand of anti-freeze I will EVER use again.
