Has anyone seen a discernable difference between the 3 SuperTech Synthetic oils?
(ST full syn, ST adanced formula full syn, ST Hi Mileage Full Syn)
I searched the VOA's & UOA's and they seem very similar in both additive packages and even viscosity for same weights.
I was looking for a full syn oil for my RV generator that calls for 5w-30 or 10w-30 and I thought the the ST syn hi mileage 5w-30 would be a good choice.
 
Supertech, Napa, Kirkland, Amazon basic oils are always the best deals. They are as good and sometimes better than other brands that costs more. Just get the fully synthetic and do 5-10k miles interval, depending on our driving condition. More short trips, shorter interval.

If possible, gets 0w20, 0w30, or 0w40, because cold starts are when the wear of engine is at max.
