Hello all, I picked up an old Dodge 1983 W250 (318 engine) ranch truck and it appears to have had irregular oil change cycles based upon the moderate sludge observed with valve covers off. Can someone recommend a good Dino oil that is high in detergents. I will most likely AutoRX first but want to use an oil that will assist in cleaning out the engine over time. Which company produces a quality oil with higher detergents? Engine has a little over 120,000 miles. Thanks!
