I use Mobil 1 15-50 heavy duty in Kansas, My bike is kept in a heated garage in the winter. It has started well down to 20 degrees F while parked outside though. Almost 100K miles and no problem so far. Hoser

I'm like Hoser, live in Iowa, 242K miles on MGM and all he has ever had is a snoot full of Mobil 1 - the auto side. I buy this stuff by the 50 gal drum, it goes in all my bikes, Trikes, mowers, and little snow thrower, treated goes in the weed eater (2 stroke). It's main purpose is for oil changes at the shop. If customers don't like Mobil 1, we invite them to bring their own oil. I think we only have 2 regulars that don't want Mobil 1 in their engines. We average about 35 oil changes a month in the shop. So every month, I have a standing order for a drum of oil. John is usually there when we open on the 1st Monday of the month. Should we run out, he will bring another barrel the same day I call if it is before 2:00 PM. Super service from this supplier.
Has always gave me good luck so I no change. Also, I don't worry about every little rattle either. I just ride, or did, the snot out of him. Son and Daughter are fulfilling that task for me now. I am dedicated to the Chevy Trike.
This bike was built to RIDE, not to piss ass around with everything on it.
As Forrest Gump would say:
“That's all I have to say about that.”
