Decent high mileage oil
The Castrol GTX High Mileage 5W-20 Synthetic Blend works good in my old Ford 5.4 engine with over 300,000 miles on it. It helps keep the engine clean on the inside and running smoothly. It burns about a half quart between changes now which isn't bad at all for the mileage on the engine and the towing it's done. I used Castrol Full Synthetic 5w-20 in the engine till it reached 200,000 miles then switched to this synthetic blend high mileage oil.
