Mate get some good quality after run oil ,like RB ,mugen or exceed .and make sure you burn all the left over fuel out before you oil the engine .
If you are using alot of oil then you will need to get rid of some before you restart the engine as it can place to much load on the piston pin.a few drops is all you need.
As far as rod wear you should replace the rod after run in .
Running to lean can also cause crank pin and rod wear.
To keep your engine in good condition you should replace the rod & front bearing every 2-3ltrs and the rear every 4-5 ltrs.
