Consider modifying you oiler, that is what makes a difference. Its a bout pressure, not about flow.
im putting a 461 oiler on my 400c soon but was just curious if anyone does it or not.

Thats gonna fit? Anyway, it is usually possible to modify the mechanics.

You want a longer bar or milling? It is probably perfect as it is - just saying...
no i just do tree work but with a 25 inch bar it doesnt seem like it is oiling enough so i got a 20inch light for it for now until i find time to throw a bigger oiler on there or mod the current oiler.

Oiling enough is surprisingly little. The 400 will give enough oil for a 24/25, even though you cant feel or see it.
Lift the chain from the bar and wiggle, you will see an oil coat in the light.

If you're looking for excess - you won't find that.
I open all my bar holes somewhat, saves ur chain and bar with a simple mod , There not as big of holes as they use to be back in the day for sure

It wont help if the pressure is not there to support it. Pressure is a lot more than the area of the hole.
The oil pump provides pressure at a steady rate- not flow, flow only comes to play at high volume - not like the steady low volume of an oil pump.
Never had problems with pressure it works a lot better for me be doing it long time
Have done it on several bars, have elongated some with a Dremel as well.
Oiler holes can get clogged up tight. I clean them out every time I sharpen the chain or change the chain. That works. Make them bigger and that makes it easier for more grime to get into them and clog.

Dont make it bigger....make another one in a row....
Calculate the area of the bar where it sits on a oil pickup line/channel...and make another hole there!

Regular bar maintenance is always good idea , a clean bar slot is a well oiled bar slot
Interesting, got any pics?

Thanks. I might try that.

I suspect bar oils have improved and therefore same flow or pressure may give better lubrication than previously.
I open all of my Stihl bar oil holes, bigger and sloped forward really helps with keeping them open and flowing oil. Chainsaw bar oil pumps don`t make pressure, they are a displacement pump style.
