How is your ticking? From time to time I scan the posts and I have not seen what I use: Chevron Delo 400 Multigrade 15W-40. You will find it locally available in gallon jugs, quart containers take some searching. Delo 400 is known as an oil for diesel engines. It is rated for naturally aspirated and turbocharged 4-stroke diesel and 4-stroke gas engines. Works well with EGR, (exhaust gas recirculating), engines due to soot dispersancy. Concerned with compatibilty of Service? API Service catagories of CI-4 PLUS and below. I don't sell it, I just use it. Use the correct filter, try some Delo 400, and post a performance note after 3k miles.
