Think about the oil temp, then compare to where it is between the dots. You don't want to be low when the oil is warm/hot, you don't likely want it near the top when really cold.

The upper notch is the max hot spot.
i think the issue Im having.. when i check it cold. it reads near empty.. I drive it around. let it sit for some minutes, check it and its in the middle (normal area)

Im also wondering, the manual says nothing about checking your oil when the engine is cold or really anything about where the level should be when its cold..

It always starts the sentence by check it after every fuel up, or let it run 10 min, let it sit than check it.

I hate to read it cold and its giving me some weird level, I add more oil than I need and now Im messing with overfill..

I read on one of these oil threads, Unabomber puts 5qrts in.. I put in 4.2ish .

besides the low reading at cold, the operating temp amount seems good.. ?

IMHO, if you are reading close to the middle of the two notches at cold, you are good to go. It's so hard to get a consistent reading due to the many factors stated, I wouldn't worry too much about it changing day to day. The issues only come from someone not check their oil at all!

I answered your PM.

Keep the oil level between the dots after the engine has been off for a few minutes after running and preferably on a fairly level surface.

I have learned to park the car on level ground after I get to work. Then I open the hood, remove the dipstick lay it on the intake manifold, loosen the oil fill cap, close the hood. After work, check the oil level, always keep it topped off.

Oh, never let the oil level get to low. If its not to the full line, top it off, a little over full is fine...it will burn off.

its reading in the middle when its warm. its reading empty when its cold. this was not answered.. thats the only problem Im having. if its a problem at all.. The manual doesnt specify crap about where the level should be when its cold.. So I guess ill just warm it up and check it that way

I like to check it first thing in the AM after its been sitting overnight. Pull the dipstick out and read it. Usually works. Depends on the Subaru though. I've had 13 and some are worse than others when it comes to getting a consistent reading. It seems to have been an issue for a long time. Dip sticks vary too. The hole at the F is for full when cold and the notch is for full when hot after the oil has expanded.

So the F and L holes are readings for when the car is cold??? therefore, if its in F or between its good to go?

Yes, that's my take on it. I think the volume between the F and L is about a quart. I usually have a partial quart of oil on hand. While you should be safe between the F (full) and L (low) when cold I usually like to add back to the full line when possible. If you don't you will still be okay, it's just something I like to do. The exception is if I'm close to changing the oil soon.

Back to what Charlie III posted on this thread; so when engine has been running (oil hot) ; and you stop to get gas and check oil levels, i usually get a lower oil reading than when the car has been sitting overnight.

so car sitting over night i get what i think are normal readings; usually over the full mark.
After car has run (oil hot); my oil level reads less than middle of the two notches.

should i add more oil?

I would not add more oil if it were me. Sitting overnight the oil has had a chance to pool back down in the oil pan. A hot motor will have oil up in the motor. If you want to check hot I'd wait at lest 15-20 minutes then check. Since hot oil expands it should be higher than the cold fill mark. The other good thing about taking a reading after it's been sitting overnight, the oil is thicker and will stick to the dipstick better to get a more true reading. I find the dipsticks have always been tricky to see the oil level.

Was just introduced to them today. What a great way to lighten your wallet by $79-89!
The vent button on top is a clever sales gimmick that does absolutely nothing. There is not anything surrounding the dipstick end, where it resides in the oil pan, that would cause pressure to create an inaccurate or inconsistent reading. Suggesting that a Subaru dipstick needs a vent to give accurate readings would be false advertising.

I check mine dead cold first thing in the morning. This lets all the oil run back down into the pan.

When I check it hot, like every other car I have owned, it reads low. So when I added oil it was over filled. Our Forester was burning a little oil but this made it seem worse. Then of course when it is over filled it leaks a little and stinks.

This is my experience with checking the oil in my STi. The only thing that gives me a repeatable accurate reading is popping the o ring off the dipstick. As I'm always trying to develop a baseline for oil consumption leaving the o ring on is a crapshoot. After pouring the measured amount of oil after a 1 hour drain and pulling the o ring I read exactly at the full notch. Leaving the o ring on will tell you there's oil in the pan, taking it off will tell you exactly how much is in there. Lastly I would like to thank one of the posters for recommending this as I never got that warm fuzzy when trying to decipher the mystery that was my dipstick.

Not really adding much to the discussion.. Just a rant. Why did Subaru decide to make the dip stick black? All the other different car manufactures that I've had is grey. Oil color blends in and makes it hard to read. Also which side of the stick is the best indicator for oil levels? Iv'e been reading the left side.

Read both sides go with the lower of the two sides.
