A hugh percentage of cars out there are under a warranty of some kind. I'll bet that not one of those warranties specifies 50 weight oil and oil changes beyond 5 to 7.5k miles. And this synlube oil is only for engines in good condition which would eliminate a lot of cars out of warranty. So, basically, if you are under warranty or have a worn engine they don't want you. Sounds like a great marketing plan. Sell to people that are willing to void their warranty. That's a good crowd to hook up with. If that's their marketing plan, I can't wait to see what the actually put in the oil. They must have the best secret stuff in the world. I'll bet we have lots of users out there, I just wish we could get some response and uoa' and all that kind of stuff.
