Take the bar and chain off and see if the little hole in the bar is plugged with sawdust. Thats the problem 90% of the time. If thats not it, start the saw and let it idle with the bar and chain off and see if oil is flowing out of the hole.

Also, if it has an adjustable oiler, make sure it isnt turned all the way down.

Do these things and report back with your findings.

You can use the corner of an old clipped up credit card to run down the groove in the bar to clean it out. I do this anytime I flip my bar. I also blow out the sprocket cavity, and the oil holes. As mentioned, the oil holes can also plug up and impede flow, but if it's just sawdust, it won't make too much difference (hard to believe, but true). If it's a chip or a solid piece of wood, then you definitely want to clean out the holes.

That said, recent model Stihls do not visibly oil like older saws, and it's misleading. You might see a light mist at the bar tip, but the saws will not sling oil like the old days. The only way to tell if they are oiling right is to confirm that you go through about 3/4 tank of oil per 1 tank of gas. On the flip side, if the chain binds and the saw struggles, then it's probably oiling poorly.

By experience, I can tell if the saw is oiling by the sound the chain makes as it runs along the bar. In fact, if you ever put a new bar/chain on a saw, listen to it and you'll hear the proper sound once the oil starts flowing all the way around the bar. It goes from making a metal-on-metal racket to something more like metal-on-butter...

I have exact same saw, new a few months ago, just ran about 2 gallons of fuel through it last weekend.

Every tank of fuel used also seemed to take 1/2 tank of oil.

Also notice when running at higher rpm chain seemed "dry" noticed by no oil mist but if I let it idle more (versus shutting it off) then chain was oily'er and when I hit the higher rpms after ideling for say 20 seconds then mist did fly off the chain onto the wood.

I have 3 of these saws well two ms250's and one 025. I have never had a problem with the bar oilers. I believe it is because I use compressed air to thoroughly clean my saw and bar every time I change chains which is often because i do not sharpen my chains while on the saw. I would say three tanks of fuel and it gets cleaned up proper, part of the reason I have 3 too I guess. I also have two MS290's as well and have never had oiling issues. knocking on wood.
Burning 2 gallons of fuel in a chainsaw takes a long time. Sir you cut a lot of wood to burn 2 gallons in a weekend!

For those who wonder -
Stihl does not like to oil too much.
And further they design their saws for their chains. Often a non-Stihl chain does not accept the oil as well as a Stihl chain.

I've got two 660's that I use for CSM.
I've had both of the oilers swapped out to high capacity oilers. The same as they ship on the saws that go to Australia.

Before the swap a 32" bar and chain combo from Baileys would run dry when the oiler was maxed. Now it's well oiled.

The oiler is driven off the clutch so it doesn't oil unless the sprocket is turning. The bar MUST lay nice and flat against the saw with no chips or grunge buildup otherwise the oil might just ooze out the side. I have seen some of the cheep bar oil (pic) 439661-bar_and_chain_oil.jpghave globby stuff in it that plugs the screen, so check your filter.
