Got some vlavoline maxlife oil additive, for cars over 75,000 miles... just over 100,000 here, 95 plymouth neon. What is this stuff? I wanna try it for my next OCI soon. HOw much thicker does it make a 5w 30 or 10w 30 oil? Valvoline all climate to be specific. Might it coke up things under the valve cover? Looking for some extra protection for my car, for the humid sumemr coming here in southwest CT, LOTS of stop n go traffic.
Thanks all
