Has anyone used the MaxLife oil additive with a synthetic or blend oil? I think it is still available and might provide the benefits of MaxLife in combination with the protection of any preferred oil.
There is a Maxlife Engine Protector additive that has been at some Big Lots stores for $2 a pint clearance. Now I see the same bottle but titled Maxlife Leak Stop or something like that. The better Valvoline additive though is the Synpower Oil Treatment.
