PetroFlo 20W-60 is a natural high viscosity index, super performance engine oil that provides excellent protection for Gasoline and Diesel engines operating in severe service applications. Vehicles with higher mileage can incur greater wear and tear leading to lower compression and higher oil consumption. This can cause loss in performance and premature engine failure. PetroFlo 20W-60 is thicker than ordinary oils and contains extra anti-wear agents. These reduce oil leaks and slow down engine wear to help protect and prolong the life of the engine. PetroFlo 20W-60 delivers high performance in both naturally aspirated as well as turbo-charged diesel powered equipment in European, Japanese, and American manufacturers. MEETS OR EXCEEDS THE PERFORMANCE REQUIREMENTS OF THE FOLLOWING: CH-4,CG-4,CF-4,CF-2,CF,CE,CD-II,CD,SL,SJ,SF,SC, ACEA: A2/B2. FEATURES / BENEFITS: High viscosity shear stability. Excellent Fuel Economy. Excellent volatility for low oil consumption. Excellent protection from deposits at all operating temperatures. Thermal and oxidation stability. Advanced varnish, sludge protection and prolonged engine life. Excellent detergency/dispersancy. Minimizes vibration and engine noise.
