Did an oil and filter change on my old tractor. Doesn't get used much so has been a few years since I did it. Used Shell rotella 15-40 but the older spec oil in the black pail. New filter from Agco. Really brought the oil pressure up - now constant on the high end of the gauge. Stays on the "L" in normal on the face of the gauge. It had 5-40 synthetic in it before and the pressure wasn't as good. I think the non synthetic is better for these old girls! Winter starts may be a bit harder tho.

| Dad's 1949 WD spent its first 40 or so years using SAE 20W-20, now has 10W-30. As far as pressure, the book says that "oil pressure is sufficient when the needle on the gauge is between the O-R-M in the word "Normal" on the guage! O, for the sake of simplier times! R. Musgrave |

| You went from 5 viscosity at start up, to 15 viscosity at start up. Yep, your oil pressure will be higher. |

I'm not talking about startup. That is fully warmed up to about 170 degrees F. Drove it a few miles. Top number is what counts when it is hot - both are 40 so should be close.
Engine is 226 gas just to clarify. It stays at 170-175 constant even on hot day. Not trying to start any argument here. Just sharing some observations as the oil discussions seem to appear here once in a while.
