What kind of oil does a 2013 Ram 2500 diesel take? However, RAM 2500 recommends SAE 10W-30 synthetic or 5W40 synthetic engine oils. According to them, the 10W30 provides improved engine protection. It works in low temperatures and reduces fuel consumption. Does a Hemi use gas or diesel? Overall, the gas HEMI engine provides the best gas horsepower among 250/2500 pickups — and more payload capacity than the Cummins — but the turbo diesel outperforms it with mountains of torque and more maximum towing capacity. Which is better Cummins or HEMI? Higher Towing Capacity: although both Hemi and Cummins engines...

What causes a piston to stick to the intake manifold? Poor lubrication can cause modern piston rings to overheat and lose their tension. When combined with excessive varnish, the piston rings can stick in a collapsed position. Excessive compression ring blowby will force engine oil into the intake air ducting or intake manifold. How are piston rings related to oil consumption? To better understand ring-related oil consumption, let’s look at piston and piston ring design. For example, many top rings are flat with a convex or barrel-shaped outer edge that contains a molybdenum inlay. The moly inlay retains oil and...
