Waits to catch the unwary, like me.
Decided to change engine oil & filter as pretty soon now have a long journey coming up. Done oil changes before but dealer did the filter at annual service . Now out of warranty doing it all myself. (And properly, if I might add a slight note of bitterness)
Well now, the oil filter is easy enough to get off as it sits on a mounting containing the oil cooler that projects from the side of the engine. It has a tray arrangement to catch the oil which comes out when you unscrew it. And the tray has a drain that lead down and terminates in the little rubber tube that is in front of the sump drain plug. Very thoughtful. Avoids mess
Unless you forget to put the waste oil container under the engine before unscrewing the filter. D'oh! |

No Offence Meant!
Yes, 'draining' the oil through the dipstick tube can work. Many years ago, Jet pertol stations used to offer this service provided you filled up with their oil. However, there are a couple of buts:-
The dipstick doesn't need to extend to the bottom of the sump. Forcing a tube down the dipstick tube to reach the bottom of the sump may damage something which is in the way.
If the 'draining' tube doesn't reach the bottom of the sump, it can't remove all the dirty oil, leaving you with semi-dirty oil once the clean stuff is then added.
As an alternative, you can spend £20 on a fancy new sump tap plus drain tube and make the oil change process a whole lot easier. I have fitted these to my cars and it makes the process almost totally painless. See:-
http://www.drainplug.co.uk/
There are several suppliers in the UK. I've found Geoff Agg very helpful so I would recommend him. The benefit of this gadget is that the draining process can be stopped part way through without spilling oil which is helpful when there are 11 litres to come out (I have a 4.2 litre Amazon engine to drain). This gives you a chance to change or empty the receptacle collecting the old oil. The drain tap comes with a brass cap which provides a secondary seal - a bit like a dust cap on a tyre valve.

I have a PELA oil extractor pump which works well on my other car but not on my LC120.
The reason is that somewhere in the dipstick tube is something that restricts the suction pipe from enetering the sump. I have tried a thinner pipe but just will not go down the tube. |

Willy,
Have you ever got 11 litres out of your 4.2? I only ever get about 9 out of mine, even when changing the filter, and I leave it draining for ages to let all the last drips out.
I also make sure it's filled to properly, may not be to top mark on dipstick, but definitely not near the bottom.
