WD40 is certainly not an oil, it is a degreaser that will leave behind a residue. It has no lubricating properties, however the residue is an excellent water repellant and is also very effective at lifting and breaking down dirt. I use motor / brake cleaner which leaves no residue behind and then oil using Trinity Royal Oil. Another good option would be a really light synthetic oil as this has higher heat resistive and load properties - our tiny bearings take some serious loads!

Dont lubricate with WD40 though or they wont be lasting too long

I just run my bearings stock....Occasionally if I'm in the mood and have the car apart I'll remove the inside seal and use some Trinity bearing oil

My drivetrain spins okay (5-6 seconds) but its smooth and lasts a long time

just soak the bearings in WD40 for 1-2 days and just wash it with air gun. It will go smooth after.....

I have my jewlery cleaner filled with Castrol Super clean... I buzz away my bearings for a few hours... Run them under water... Soak in WD40, usually overnight... Then I use a good Oil, depending on what I have at the time, I change my oils like my undies...

WD40 is a penetrating OIL.... It's basically a mixture of oil and kerosene... It's great for getting into things, but doesn't last long...

Like Burbs, I have used valve oil (from music store) for many years. 4 oz bottle is about $5.

Best thing is that you can also use it for comm drops. Works especially well in 4 cell cars.

Not much make the bearing roll smoother. If its works on cars and skateboard bearings it should work on the car,
