Oil for motor's ball bearings

[Alfa Spirit]

Just needle oiler with trinity bearing oil is what I use. Easy and just a drop on each is all that is needed. You need thin oil to get past the shields and to the bearings

I bought Trinity oil 4025 (thin) for ball bearings

the one i use says for modified motor bearing its thinner than the royal oil i use from them in my nitro car bearings

[Mel279]

I use oil that contain PTFE(teflon)
