Default Me and my stupid noobiness

Hey all,
I was checking the oil the other day (when the engine was cold...) and saw that it was a little low. so i added an enough amount for it to go back to the full mark. Anyway, i checked it today when the engine was warm. I got home, let it sit for ~15 minutes, and then checked it. It seems to be overfilled, the dipstick reads about 1 centimeter passed the Full mark. I need to drive from Houston to Dallas tomorrow (250 miles). Do i absolutely need to fix this before i go, or is it not that big of a deal? Please let me know.

Thanks

Not a big deal. Do you remember the notch above the full mark? It may read that high when the oil is hot. The temperature of the oil will make a big difference in the readings. Make sure the car is level - or at least parked in the same place - when you check the oil level, too. Even a little change will effect the reading on the dipstick.

Ill post it again.

Dipstick reading 101

hole closest to the bottom = low (about 1/2 qt)
next hole up = Full when the engine is cold
Notch on dipstick = Full engine at normal operating temps.

To check oil properly when engine is cold, start the engine and let it run for a second or so, turn off the car then check the oil level.

In the manual for my VW Passat, it warns that overfilling engine oil can lead to fouling of the catalytic converter and kill it over time. Wil the Boxer engine be any different? If I only had the manual for my 2.5RS with me...

Overfilling the oil can cause frothing, and frothing is bad. What that has to do with the cat is beyond me, but whatever. I for one would be more concerned with my main bearings than with the cat...much, much more difficult, time consuming and expensive to replace (if you count labor, anyhow).

IIRC, the crankcase is tied into the air intake through the PCV system. Excess oil-->less air space in crank case-->higher crankcase pressure-->higher chance of (more) oil getting into the combustion chamber and then out the exhaust. Something like that...

Yeah, I know that overfilling can cause very bad things, but we're talking about 1/4-1/2 qt MAX...Probably only about 1/4 qt...can this really cause such bad things?

I would agree that 1/4 qt wouldn't do any harm. I don't know how much oil it would take to change the dipstick reading by 1cm though.

Can I sugest getting one of these? http://www.fumotovalve.com/ Not only does it speed up oil changes and make them less messy but it also allows you to drain a little oil if you overfill by accident...
