GLE350 Oil change and weight
Taking delivery of new GLE 350 with AMG body option early next week. Excited but still skeptical of the little 2.0 liter.....




Today’s engines can easily run 10,000 miles with 20 weight oil and with out adding between changes. 20 weight will have less friction than 30 weight so slightly more power and better fuel economy, maybe slightly better engine life. As to longevity…you will get lots of opinions pro & con. My experience with 3 higher mileage vehicles has been very good using 0-20 weight oil. None have seen increased oil consumption after 40-50k. One truck with lots of towing miles (close to max weight) did not change much at 55k when I sold it. I did change oil at 7500 miles. You might find some decent technical info with an Internet search.




Lower viscosity formulations flow faster and smoother through the oil pump, requiring less energy to transfer lubrication throughout the engine. They reduce friction between the piston compression rings and the cylinder walls, minimizing metal-to-metal contact and prolonging the life of your engine components.
In simple terms, the word viscosity relates to a fluid's resistance to flow. Most later engines are designed to use low viscosity engine oils to reduce internal drag. This takes less power from your engine, reduces fuel use, lowers exhaust emissions, and improves engine responsiveness.
