*I use M1 10W30 in my Honda Lawn Mower - never considered using M1 10W30 HM ... How did you come about this choice ?

Thanks typ901. I had never heard of this series, but should have just searched for it vs. "Honda GC vs GS vs GX." Perhaps I have too much faith in Google?

Thanks punisher. The iron sleeve had caught my attention as being something above and beyond the GC series. I am happy to report that it is a very smooth running engine that starts easily and is relatively quiet for its size. I feel pretty safe in assuming that there is a good NGK plug in it already, as opposed to the Chinese Torch brand plugs in the last three pieces of OPE I've purchased.
Thus far I am impressed with the performance of this machine. The volume reduction is substantial. I would say that it is
as good if not better when running over fresh leaves than what I used to get with my older Craftsman leaf vac AFTER having first chopped them up with the mower. This machine also sucks up the outer hulls of hickory nuts, which are a real problem in sections of my lawn. Thus far I have not tried the chipper chute.
The manual is old school, recommending the first oil change after five hours. Based upon the volume reduction and bag size, that might just complete the leaf season. The manual calls for 10W-30. I plan to put it away for the winter with a fresh fill of Mobil1 10W-30 HM for its 3.5 HTHS viscosity. This oil is serving me well in other OPE applications, although I also use T6 5W-40 in other OPE applications. Somehow I've just never been able to see a reason to put an XW-40 in a real Honda motor. Chondas, yes; Hondas, no.
