Whats the best oil additive for a four cylinder. There are so many. I think zmax?
If I were you I'd just make sure it is full and drive on!
use a product called restore its comes in a silver can with black writing
In my opinion it is definetly Lucas oil stabilizer, additives work by increasing viscosity, this product is thick and has friction modifiers added to it, great product. They also make a great fule additive, for keeping fuel system components clean.
I Agree with Chris on this one I use restore everytime i change my oil and have ever since my engine reached 75000 miles now I use a high mileage oil like Valvoline max life and restore and now my car has over190,000 miles and I have never had any problems
