Xantia oil Change - with extraction pump?

markw · Post by **markw** » 23 Jul 2007, 11:05

Hi, has anyone used an extraction pump (like this one: http://www.cdet.co.uk/catalogue/product ... ctid=PL650) to do an oil change? Can anyone forsee any issues?

Oil changes on my Xantia 1.9TD are a right pain at the minute - as the sump has at some point been cracked and the bottom plug welded into place.

A right pain ?

How do you drain it at all without the bottom plug ????

Regards,
Simon

Yes I have used one exactly the same with no problems.If you really do not want to change the sump you can get a cheaper version on Ebay for changing the oil on a Smart car which has no sump plug fitted,just search for Smart car suction pump.
Hope this helps,

Oooh, I like the idea of that! Saves messing around in under the car!

Can't possibly see how this will give you a good oil change. There's bound to be at least a litre of old oil left on the floor of the sump.

Dont think so John.

If you jack the car RHS front lift point and set the height to low, the oil will collect at LHS near the dipstick in the sump, which is where you probe with your pump.
Nothing close to a liter will be left, but maybe a couple of 100mL's. That is well adequate to ensure the oil is fresh.

These types of extractors have been around in the motor trade for years. As I said on a Smart car you have to use one as theres no sump plug.They are used a lot in the marine industry due to the inaccessibility of a lot of boat engines

People do talk about the advantages of speed, convenience and cleanlieness but they neglect to explain the disadvantages of an extraction pump.

When you remove your sump drain plug, the oil rushes out and carries out with it things that have settled in the sump, thats soot typically on a diesel. If you use a pump, you won't get the same flushing effect so the some of the sediment stays in the sump that would have been flushed out.

There are some situations where you have to use an oil extraction pump, for example in a boat where you can't get a container underneath the engine to catch the oil running out but the best method (short of removing the sump) is draining quickly by gravity via the sump plug.

Yes, I did envisage jacking the car to one side, but I still don't see how you know a flexy, curly plastic tube will go exactly where you want it to.

It's better than not changing the oil at all and I'm pretty sure most main dealers do it that way nowadays.

For any car that has sump plug issues I'd say it's a satisfactory solution.

Using the top plug and then using a single action pump to try and get as much of the rest out as possible from underneath - gets messy! And probably not giving it great oil changes..

oldnail, - is the tube on the smart suction pump definitely long enough for a xantia? I can't find the length of the tube online, but imagine the smart engines are quite a bit shorter?

Turn the car upsidedown and give it a shake? It works with my piggy bank!

I stick high power magnets on my oil filter in the hope it will trap ferrous metal particles that could be small enough to get past the element. I get the magnets from old PC hard disks. For free it's worth a try.

The extractor I've used is the Sealey vacuum type which comes with various size probes which go down the dipstick hole.Will empty out a 5Lt sump in minutes.
