10w-30 will be good, but 15w-40 is about as good as it gets.

Rusty and Zach are on it. I would go with 10W-40 if you live in the north (Central Canada) and need it to start in the winter, or 15W-40 every where else. Brand is less important than quality. Change the filter as well (be sure there is a new canister seal, a square section "O"ring) and be sure to fish out the old filter can seal from its groove.

15w-40 here in SE WI. I use it in everything from my JD 318 mower to all my old tractors.

I use straight 30W here in CT

Those old H's are pretty forgiving. You can use most any oil and they will survive, I use straight 30W in mine but I don't use it much in the winter.
