Exact Antifreeze Brand - ZR-1 Net Registry Forums

If the vehicle is driven in summer months only a 50/50 raitio is not needed...infact less antifreeze is better for cooling. A 50/50 raitio is recommended for cold weather driving but less antifreeze is recommended for summer cooling and lubrication of the pump.....less antifreeze and more water = better cooling. I use a 50/50 mixture beacuse you are correct in that some water will still be in the block so the end mixture is likely about 40/60.
