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 15w-40 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 15W-40 is too heavy for winter use. This tractor gets used year round. Any thoughts?
Thanks,
Mike
