Hi All,
I've been lurking on this list for years, but now have come up with a question I can't find answered in the archives. I have a Massey 255 with a Perkins 4.236 diesel engine. Prior owner told me it was hard to start when cold (below 40 F), and he was right. He also told me he ran 15w40 oil in it, year round. Looking at the owners manual Massey recommended the follow oils:
Above 90 deg - SAE 30
Between 32 and 90 deg - SAE 20 or 20/20W
Below 32 - SAE 10W
I can't find the second or third viscosity oil anywhere, and I'm wondering if the 15w40 is too heavy for winter use. This tractor gets used year round. Any thoughts?
Thanks,
Mike
