I didn't see a reply to this question, so I'm asking again. I purchased an evacuation system, but clearly the tubes aren't long enough. Is the length and diameter of the suction tube which goes into the dipstick port known?
Have about 10000 miles on a P400 and feel it's time for an oil change.
Thanks

The Mityvac I used for my old LR4 was a bit too small to extract all of the oil from the Defender (I believe the capacity was 8 liters or so), I had to "upgrade" to a larger pump with a 9.5-liter capacity so I could vacuum all the oil in one shot, and with the warm oil naturally growing in volume, even that capacity is barely sufficient, as you can see in the video. Are you sure it's not just the pump shutting off prematurely because it's almost full (it does have an overflow control valve, IIRC), rather than because all your oil is extracted?
Also, how do you know for sure that the vacuum pipe is at the bottom of the sump? It could be too long (and could possibly curl back up when it touches bottom), or too short, and in either case you could leave a couple of quarts of oil in there.

Same here, the 9.5L OEM tools pump was filled to the top. I have a question regarding that OEM tools pump...did yours come with a cap to close the opening where the large tube attaches to it? I have a threaded cap with just a big hole in the middle of it.

No cap / lid was supplied with mine, either. I guess the large tube is supposed to remain attached to the pump with that threaded collar at all times, except when emptying the body of the pump from used oil, which can get messy if you aren't careful. I liked the way the Mityvac pump would empty a lot better.

Question for anyone, but hopefully umbertob is watching, as he originally posted this sticky thread and seems familiar with changing the oil. I am planning on purchasing a MityVac, but being old school, I was thinking of doing the first change at around 1000 miles and doing it the old fashioned way via the drain plug. My thought process behind this, though with newer manufacturing techniques and tolerances it’s probably not an issue, is to make sure any particulates or metal castoffs are removed via the movement of the oil due to gravity. I have a mental picture of the long tube inserted through the dipstick tube only sitting in one location, missing anything clinging to any corners or the bottom of the oil pan out of reach of the inserted tube. Might be overkill, but after that initial change, then using the oil vac for any future oil changes. Anyone with an opinion on this method?
