If you are using a QUALITY engine oil that almost eliminates skirt wear. If you aren’t paying 20 plus bucks a quart (liter) you aren’t getting an oil that will do the job you want it to.
The other thing to do is run near .000 piston to wall clearance and increase the bearing area and oil retention of the piston skirt.
There is only one way to do that at this time and that’s with skirts coated by Line2Line.
The use an abradable coating that you can have applied to run near zero clearance (.0015ish) or they can apply it so you run at .0000-.0005 but you really need a dyno to do the latter and it helps to have a dyno either way.
Break in is kinda critical with the coating because you need to load the engine to get heat in the piston so it expands and wears the coating off (and in).
Just getting the engine up to temp won’t do it. So you need to get some load on it, then take the load off and repeat it.
