my truck calls for 7 quarts of 5w-20. the motor oil i'm using at the moment has this product spec: 8.65 @100 cSt, 46.96 @40cSt. i'm going to add 16 ounces (half quart) of CD-2 Street Legal Oil Booster (35.0 @100 cSt) every oil change. so that would be 6 1/2 quarts of 5w-20 & half quart of CD-2 Street Legal Oil Booster. could someone please tell me what's going to be the end cSt @100 celcius? thanks!
