I have run my 850 Commando on 50 weight for the past 2 years, prior to that I ran a 750 Commando & a 650 Bonneville, both on 50 weight oil, no evidence of damage / oil deficiency in any of the motors. Advice from Norvil, Mick Hemmings and Hughie Hancox to run 50 weight in warm / hot weather & 40 weight in cooler weather would indicate some wisdom in ignoring the venerable " Owners Handbook ".In the absence of an oil pressure gauge on any of my bikes I can't say what the pressures are/were hot/cold.I guess it is a matter of choice.

I currently use Valvoline Racing 50W in the summer and 20-50W in the cold weather. I would use Mobil 1 as I do in my cars but it's too expensive to change every 1,000 miles as I do. As an aside I recently bought two filter adapters that allow you to use a $2 fram filter (Walmart). I got them from different sources, Colorado Norton Works and another source for $8.95. The one from CNR seemed to be of good quality. It was made of steel, it came with a Wix filter and a list of others of the same Spec.(cost$15.00). The other is made of aluminum, and while we're dealing with a relatively low pressure on the return side, I don't trust it and I doubt that I'll use it. My instant impression when I opened the package was, it looks weak. Just my opinion and a little info, for what it's worth.
