While reading through my friend's June issue of Road&Track, I came across an advertisement for Valvoline Maxlife. All seemed well until I noticed that the red bottle of Maxlife in the picture had 5w-20 on it. Is Valvoline coming out with a 5w-20 grade in Maxlife? Their website does not show this oil in 5w-20 in either blend nor synthetic. Anyone have any information if Maxlife will be available in 5w-20?
