I've read several post about people trying to thicken their oil by adding VSOT (not sure what that is) or by other means, and I'm not talking about old, worn out engines. I've been reading about people doing this in healthy engines. Why? I ask because so many people rave about synthetic and how well it flows, but then you have others trying to thicken the #@$%! out of their oil. I thought from reading here on BITOG that thinner oil that stays in grade is better. One particular memeber (Tallpaul) talks a lot about using Maxlife. I'm using Maxlife right now in one of my cars, but not so sure I want to stay with it. Although Maxlife is a GREAT oil with an excellent add package, my engines are always tuned and running perfectly, which leads me to beleive I should be running a good energy conserving oil in them. Any ideas on this line of thought?
