Dry start is when the the valves, tappets ect. clatter on start up and then quickly quiet to normal. It is generally attributed to the horizontally mounted oil filter letting the oil in the filter drain back into the oil pan when the engine is off. The clatter occurs while the filter re-fills with oil thus preventing oil circulation past the filter until the refilling is complete. The drain back valves mentioned in the videos are supposed to retain the oil in the filter while the engine is shut down.

There are a number of threads on this board discussing and cussing filters for dry starts. Some people swear by one brand while others swear at the same brand. I use the Fram Tough Guard and have never had a dry start with it. Others will swear at it because they had a dry start but love Mopar filters. Me, I had dry starts with the factory installed Mopar filter.

When it was time for my 1st oil change the posters in the most active thread I came across appeared to be favoring the Fram Tough Guards and Mobil 1 5W-20. I was all ready planning to run Mobil 1 5W-20 so based on that thread I went with the Fram's. Threads since then have favored different brands. Hope this helps.

You have a diesel so dry start is a non-issue. Diesel filters do not even have drain back valves. You only worry about dry start on gas motors.
