Re: an oily mess
- Have you ever tried to pour a bottle of 20W-50 oil when it's colder
than 20 degrees F outside? It's like trying to pour warm fudge or
cold molasses. Now imagine your poor Yugo's starter trying to move
the pistons and crankshaft through that stuff. Even regular 10W-40
becomes problematic when the temp drops below zero F.
If you want to use 50 weight oil in the New England winter, you'll
have to use a synthetic or synthetic blend rated at 15W-50, 5W-50 or

I'm not sure if you were intending to call me an
idiot or not, but I can tell from your note that you
didn't get the point I was trying to make. Pour point
and viscosity are related, but you can't equate the
pour point with viscosity in the same way with
synthetics and dino based oils. Synthetics typically
have a much lower pour point than standard motor oils.
