So I did some oil samples on a boat we are looking to purchase. It has dual Cummins 480 CE 8.3 engines. This was one of the results I got back. The mechanic seems to think the high iron content is because the boat sat for several months and was started multiple times to show people at the slip but never completely warmed up or run. Oil was over a year old. What are your thoughts? Really nice boat and want to make it work but also do not want to be doing a motor in several months. It seems Polaris Labs ear on the cautious side versious other labs like HO Penn. Thoughts?
