excellent motor oil for diesel engines.

I have been using Chevron Delo in all my diesel engines for years with very satisfactory results. If it works don't change it.

Great oil, nice delivery.

It is hard to find this Chevron oil in town anymore. It has been in my farm tractors for decades, great protection from wear and tear. This is a nice way to keep the oil that I love.
