20W-50

A 20W-50 engine oil is typically used in older vehicles or in particularly warm climates. Castrol GTX 20W-50 has been specially formulated to help extend the life of your engine by keeping it free from sludge, even when operating in extremely high temperatures.

GETTING THE BEST 20W-50 OIL FOR YOUR VEHICLE

For conventional  20W-50 engine oil, it will flow like a 20 Weight oil in cold weather, then with the viscosity of a 50 Weight oil once the engine is up to full temperature.

 

Choose Castrol® GTX® 20W-50 which is formulated to clean away existing sludge while preventing new sludge formation to help extend engine life. It is also liquid engineered to resist viscosity and thermal breakdown.
