Magnatec is a fully synthetic oil and whilst it is compatible with mineral oils I would drain off whatever is in the car before you use it. Be advised however that modern oils contain detergents that loosen older deposits inside the engine, which might subsequently affect engine wear. Remember there is no filtration as such in a standard engine except the sump gauze. If the inside of your engine is clean, then perhaps OK. However compared to a straight SAE30 or a 20W/50, Magnatec synthetic oil is a lot more expensive. If your engine burns oil then it's false economy. (If it's black when you take out the dip stick then it's burning oil)
Sump contains 4 pints.
