Its all explained in the SAE standards that may be found in engineering libraries. Probably in the lubricant catalogs from some oil companies. All the numbers show a range of viscosities. Each number has a range assigned, W or the lack thereof shows the range of temperatures the viscosities are tested over. Typically W indicates a maximum viscosity at a low temperature while the plain number indicates the viscosity at some elevated temperature. Ash is what's left after burning the oil. In a real oil pumper lawn mower I've had trouble with oils leaving enough ash behind to hold the exhaust valve open and make them stop running. Low ash oils prevented that (as a set of rings should have too). In my opinion its wrong to not use the latest high quality detergent oil in an old engine. Sure it may loosen up deposits, but those deposits were not benefiting the engine anyway. Look at how much longer modern engines last in cars compared to how they lasted in the late 40s. I don't think its all design details, I think its the oil. Modern oil not only has detergent to keep the engine clean (and oil getting to the bearings), but has additives to make it stay oily over a wider range of temperatures and pressure loads, plus additives or refinement to keep it from corroding copper and silver based bearing materials so the rod and main bearings just plain last longer. Since an old tractor engine likely sits a lot more than it runs this last anticorrosion additive is probably the most important. Many would agree that there's nothing better for an engine than Shell Rotella T. Gerald J.

What Oil Should I Use? - by Francis Robinson. I keep seein this question pop up over and over again in discussion groups all over the web.
