What was the consumption on straight 30?

It fell somewhere between the 10W-40 and 20W-50 syns. The 5W-30 is the only one that I actually had to top off between OCIs.

Even back in 1979, Case recommended SAE 30 or 20w40 for the 10hp Kohler K341 in my Case 220 tractor; Joel

Interesting they equate a 20W-40 as being their "equilalent" to a 30wt...as far back as 1979. I think they got it right for their engines a long time back. I use a 30wt such as Optimol or 15W-50 Synthetic.

They are $100-200 engines... dump whatever in them and they will run longer than you need them to.

But I'm only 7 years old...are you sure of that!!!

Yes.

It's sad we seem to be finding that the equiptment manufacturer that the engine is mounted on seems to know more about oil than some of the engine manufacturer's. Use any oil you want? It does not matter? Well if you are seeing a sheen of metallic particles in your oil you first have to rule oil that the oil is not well suited to the engine's needs or it is not being changed often engough.
