I have been using mobile 1 for many years. It is a great oil, at a discounted price and in stock. My only problem when ordering is the default was on one gallon and kept giving me an error message saying this product would not work with the vehicle in my garage. Once I selected the 3 gallon option, it was fine.

Protects and Runs smooth

I use this Mobil Delvac synthetic oil in a Toyota Land Cruiser Prado with a diesel engine 1KZ-TE. This oil is excellent and runs quite. I changed the oil and filter at 5,000 miles and the viscosity and color was normal. Mobil engineered a top tier synthetic diesel engine oil!
