skateboard bearing lubrication?

can i use gear oil on my bearings for my skateboard?the oil is thick 80w 90 thanks.

You can but I'd recommend a silicon or synthetic based lubricant just because they lubricate a lot better than standard gear oil.

. Judging by the wheels I've handled (admittedly not a whole lot), it's definitely not gear lube (~90 weight). More like WD-40 (~5 weight).
+1.
5 weight is more like kerosene than grease.
The "load" on a skateboard is not much of a load at all, and when I could still ride one it was basically a mode of transport. We rode all day with no ill effect.

Use white lithium grease. You can get a tube at hardware and automotive supply stores for $5 or $6 dollars.
White lithium is clean, has the correct consistency, is safe for most plastics and is easy to use. I always keep a tube around my shop and use it to lube the bearings in my shop tools, the garage door opener, bicycle chain and most anything else that requires a light duty, moderate heat resistant gear lube.

Thirded.

Don't use WD-40 or oil as its too light and is pretty much only good for 'cleaning' the bearing.

Yes, it's grease that you need.

I'm going back about a million years, but when I was a kid, we used to clean our bearings in kerosene. This washed out all the crud, but left an oily film which acted as lube.
I found that even using the smallest amount of grease would provide drag on the wheels ( that is when they were spun by hand while holding the board upside down to see who's wheels would spin the longest) but no noticeable difference when actually skating.
I may have been kidding myself back then, but using kero caused no problems, and the wheels would spin for ages.

Any modern day skaters out there have a better option?
That kerosene will remove almost all traces of lubricant, hence why it seems to go forever with no load. Under load it puts a lot more strain on the metal -- as others say, stick with proper grease. It's sticky and thats a GOOD thing when under load.
