I've running a redtop in my truck for two yrs has not given me any problems (knock on wood).
Yellow top is suppose to be better but from what I see from a month to month basis, I see more yellow top come in for warranty exchange then the redtops. I'll see maybe 1-2 redtop come in for warranty 3-4 months. Yellow top are more frequent. I work at a autopart store. Last wheeling trip, I left my ignition on all night (not knowing). Next morning, engine started right up!
