10W Oil for Distributor
« on: August 13, 2014, 04:24:47 PM »
     So I read in the 1960 manual you should put 10W oil in your generator and distributor.  Not 10W 30, but 10W. Can you still buy this stuff cause know ones heard of it here. What are you guys using?

I use sewing machine oil in mine just because it has a nice oil tube on the bottle. I think it's not that critical. The only critical thing is NO oil. No oil is a bad thing, not that it needed to be said.

In other words, 10W30 will be fine.

Using 10W-30 is just fine.  I fill a small oil can with a flex spout and have been using
this for years for those applications.

The 30 means when it heats up it gets thicker instead of thinner, this is a good thing.

Actually, it doesn't get thicker when it heats up.  What 10w30 means is it has the viscosity of a 10-weight oil when it's cold (~ 45 centistokes @ 40C), but the viscosity of a 30-weight oil when it's hot (~10 centistokes @ 100C); higher numbers = thicker, more viscous fluid. [ref: http://www.bobistheoilguy.com/viscosity-charts/]

I've been told the "W" stands for "winter", but can't cite that as fact.

Umm? huh?

SAE 30 is not thicker (more viscous) than SAE 10?

30 is thicker than 10 at the same temp.  But 30 in a hot engine is thinner than 10 in a cold engine. When the engine is cold, the oil says I'm a 10. When the the engine is hot, the oil is a 30. A hot 30 is thinner than a  cold 10, but thicker than a hot 10.  So a 10w30 is the same viscosity as a 10 weight oil when you start the engine, and a 30 weight oil when at operating temp.  It does get thinner at temp, but not as thin as it would have been in a straight 10 weight oil

I believe that I read somewhere that sewing machine oil is 10 weight so it should be fine.

I've been able to find Kendall 10w at the local NAPA.
