It almost feels better just knowing my
engine will be safer starting in the cold and

Are you running a full synthetic now? If not don't switch you could develope oil leaks after a few thousand miles. So far none of my customers want to use it. Not enough actual real world info yet.

Yes valvoline max life. Natural gas promoted better cold start so I went 5w20 instead of the usual 30 and I have noticed a considerably more quiet cold start. 2.0 dodge neon, which I'm sure there are tight places in. I was always hearing tapping so I got the valvoline guarantee at 90k :/ yikes! But decided I would give it a try because the science is there! :-) and then a friend told me his older truck had developed a wax, should I avoid using this in the winter? Or was this a user error?
