Too much oil or not?

Ok I will admit I am a very newbie!
I changed the oil/filter in my 05 Boxster S following the capacity levels in the manual.
It says 2.05 Gal or 7.75 Liters.
I put in 2 gal and my dash meter is showing completely full.
Do I need to try to drain some out or am I ok?

Thanks
:confused

I think the accepted oil level is one bar below full feeling that a full fill may overwhelm the air oil separator. However, I've been running at completely full for some time with no issue.

KN is correct, 1 bar below the top mark is the correct measurement. The reason you don't want to go to the top bar is the inaccuracy of the bar graph. Below 50% of a bar will show as the lower bar and 50%+ will round up to the next bar. So if your graph shows at the top bar, you may be up to 49% of a bar overfilled and the graph will say just full.

An easy way to drop the level is to remove the oil filter canister and dump the oil from it. That should drop you a bar on the graph.

Mine is right at the top bar (where the arrow points) but not over. Do you think I should dump some? If I loosen the canister will it come rushing out.
Thanks

How much oil per bar?
Dang I wish I just had a dip stick on this thing...
Also is the manual wrong or does all the oil not drain?

How long did you allow the oil to drain? was the P car level when the oil was drained?
Some let the oil drain overnite; others let it take an hour or so for a complete drain.
It is possible not all the oil drained, but if it did and you put in .05 less than the prescribed manual states you should be fine.

Dont forget to read the level at least 10 -15 minutes after you turn off the engine. Before that the oil is not fully returned to the bottom of the engine (pan).

Just sayin !

05 Boxsters don't have dipsticks?
I had no idea. Seems like a bad idea..

Depends how lucky you feel. At that top bar, you could be at an over-fill situation. No way to know for sure. Your engine will try to push any extra oil out the combustion chamber and exhaust. Not a good way to lower the level.

The only oil that will come out when you remove the filter canister is the oil that's in the canister. That's the genius of this procedure for lowering the amt of oil - you only remove a small amt. Pulling the drain plug is inaccurate and messy (reminds me of the joke about the trained monkey putting the cork back in a cow).

Awesome thank you all for the info I will pull the filter tomorrow and dump some oil.
Question: Is it possible to use a top side oil remover to suck some oil out through the oil fill port like I do with a boat?
Thanks again!

e
So I just found out that you can’t use a topside boat oil remover as there is an obstruction about 8 inches down.

Now on to plan B pulling off the oil filter cover... when I changed the filter I filled the cover 1/2 way then screwed it on. If I dump this oil then put it back on empty will it refill on it’s own as this will put a big air bubble in the system.
Just wondering...probably a stupid question but better safe...
Thanks

Worked Perfectly!
When I unscrewed the filter housing approximately 1/2 a quart of oil came out and after I took it for a spin around the block and waited 30 min for it to settle my meter read one bar below full!

Thank you for all the great help!
