Tastes just like the other green coolants!
Mixes well with other green coolants. I tested it with a hydrometer before adding and it came with the proper mixture of coolant and water. It has been working well for the past couple of months.

perfect for LT1 SBC 5.7L and post 90's gen 1 SBC 350
Only coolant I use in my 1994 LT1 engineWorks great keeping a hot running engine coolGotta remember to mix with distilled water - it's concentrate - it's double what you're gettingFor pre 90's 5.7L SBC, works well keeping running and idle temps down and within safe rangeI'm using SPAL electric fans, so not sure how well performance would be with fan clutch or non electric system, but runs clean and cool across the operation range with 50/50 mix and a 170 degree thermostat

Good deal!
Good product for my old truck. I'd say for the price it's a good deal. I've always like using zerex in the cars that use it.
