Received the latest used oil analysis UOA today for the 1995 DD 12.7L 60 series in our Prevost motorhome. Engine has 96k miles on it.
I think all is well. Oil and filters have been in place 22 mths and 6100 miles. No makeup oil was added. The oil in this report #4 is Mobil Delvac Super 1300 15w40. The oil filters are Fleetguard #LF9620.
Oil in reports #2 & #3 was for Chevron Delo LE 15w40. Report #1 was for a mix of HDEO that I had and wanted to use up at that time. I always use Fleetguard LF9620 oil filters. They are a full flow and bypass filter in one. Here's a link about that technology: LINK
I will leave the current oil and filters in place for at least another yr.
What say you ?
