too much oil

[vpads]

does anyone know a way to syphon oil out of the sump? maybe thru the dipstick tube?

I accidentally put five litres of shell helix semi synth in and it is way over on the dipstick and i have noticed fuel consumption is up and the car is running a little rough now

loosen the sump plug off enough to allow it to drain slowly and drain about 1.5 litres out.... syphoning? I've syphoned petrol out before and that left a nasty taste for about 3 hours..

i wouldnt drive your car with that much oil in it, youll need to get it out quickly, if your going to be driving it

wats the harm with that much oil?

[bush_basha]

if you over fill your car with oil you can cause an hydraulic lock in your engine

To get a hydraulic lock the oil would have to be several times more than the sump holds. The main risk is to the following:
1] The oil could be whipped to froth if it comes into contact with the crankshaft.
2] The expansion of the oil could pop a seal or run out of any non contact seals such as front crankshaft seal if its the type that runs in close proximity to the crankshaft or is a felt seal (I'm talking general here because I think the commodore engine has a lipped seal).
3] Oil could be blown out the dipstick tube and I have seen an engine where it lifted the dipstick up enough to vibrate out when the engine was reved (4cyl engine had 8 litres in sump when mechanic put oil in the sump and his ever helpful apprentice came back from the loo and put some in as well).

Just drain it out of the sump, quick and easy .

I destroyed an engine years ago by overfilling it with oil.
