the 90 and 94 series recommend oil only changes at 100 hours and oil and filter changes at 200 hours. I have been changing them both at 100 hours. I run between 200 and 300 hours each season and have seen a lot of literature from CASE on 600 hour change intervals with their no 1 synthetic oil. What are your guys thoughts on oil change intervals on these engines using traditional case no 1 15W40 oil? can the interval safely be extended?

Oil is cheaper than engines.

Most of us change oil too often. But it makes us feel good, and if we recycle the oil....mothing wrong with feeling good. Just my opinion. ;)

We did some oil testing several years ago, and found all the tests showed the oil was still good at 200 hours. We now change at 150 hours. Use JD +50 oil in everything.
