I think any aluminium compatible ethylene glycol type like Prestone., any standard oil in the proper viscosity,
DOT3 brake and clutch fluids. 10 or 20 SAE oil oil for the carb dampers. Gearbox and rear end - 90 -140 SAE
wheel bearing grease for wheel bearings. Regular gas as the compression is only 120-130psi in all cylinders, but I would use 91 octane if the compression was as it should be (160-180 psi). Regular grease for all suspension parts.
light grease for hinges and hand cranks , 30 SAE for throttle linkage and choke cables., a little grease on the wheel nuts or knock offs..
I live in Ottawa, Canada. Very cold (-35C to + 35 C) which is -32 F. to 95 F.
I do not drive in the extreme cold temperatures. Only down to 0 C. (32F) usually in November and only at night in the very hot summer...
