Maybe for sno-blower use?
As a very general rule, air cooled OPE engines do not have any way to control oil temperature. The age-old standard of a 'straight 30' oil was a valid choice for one reason. A straight 30 has a HTHS of about 3.8. Meaning the oil retains sufficient viscosity to protect the engine when the oil temperature climbs into the 250+ degrees F range.
Today's 5W-30 oils have an HTHS of about 3.0-3.1 and can, in hot climates, fall short of the high temperature protection many air cooled engines require. The 0W oils typically use more viscosity index improvers and are generally more prone to shear over time. For this reason, the 0W oils may not be an ideal choice either, even with a robust HTHS spec.
I choose Mobil 1, 5W-40 Turbo Diesel Truck for most of my OPE and Mobil 1, 15W-50 for my generators.
