This doesn't sound right to me. Oil blenders formulate an oil for high mileage engines but its bad for high mileage engines?
The same website has a list of synthetic oils that are compatible because they are GRP III so what's the deal with that?
Softening seals then re hardening them with dino sounds a bit hocus pocus to me.
Trav, lets remember that it is auto-rx's belief that synthetic oil's are bad for seals under certain conditions, do they have any proof or tests to back up there claims, we shall see.
In most cases Rear main Seals or any other seals in our engines are probably hard as a brick or they are torn, the best advice is to just replace the seal.
If you have a car that is either 10 years old or has over 100,000 miles then there is almost a 100% chance that auto-rx will not rejuvinate your seals. JMO
