OK GP Classic 20W50

OK GP Classic 20W-50 motor oil is a premium quality engine oil for gasoline and diesel engines, both normally aspirated and turbo-charged. The state of the art additive package protects your engine even under the toughest conditions. It can be used when the fuel contains some sulphur contamination and will allow for extended drain intervals. This special oil quality was developed to prevent "bore polishing" in diesel engines and is suitable for application in Euro 4 and Euro 5 engines.
