A couple of months back I bought a Vacuum Oil Changer Pump -- the type of pump that sucks the oil out through the dips stick hole.

Yesterday I used it for the first time to change the sump on the son inlaws Rover 45. I must say I was impressed you can almost completely empty the sump through the dip stick hole -- all that was left in the sump when it was removed was about a generously sized table spoonful of oil -- and that would probably have been sucked up the car had been sitting level or jacked tilt it towards the dip stick.

But the really good points is it makes zero mess both when changing the oil and at recycling centre..

However if you buy one of these it is much cheaper to buy it from a yacht chandlers not somewhere like Machine Mart. The brans to look for are Pela or Seago.

Got the same one,use it for bleeding brakes and clutch too

Hi Britishtrident, what is a good price for one? I've seen the Piela 6000 for £36, is that about right?

40 Inches, How did you use it for brake bleeding? Suck the brake fluid through the caliper nipple?

I've always been put off these cos surely sucking the oil out the dipstick tube may leave metal fragments or other crap collected at the bottom of the sump behind or even worse suck it up but not completely remove it.

Or is this not the case?

Or you can build an electric one for nowt.

I got an empty gas cylinder, the ones that are about knee high and unscrewed the valve on top. It is a standard water pipe thread.

Fill the tank with water to make sure all the gas is out and drill a 0.5" hole in the top shoulder and weld a short length of suitably sized exhaust pipe over it - while the water is still in the tank please to avoid meeting your maker sooner than you anticipated.

Screw in a water pipe fitting - I think it was 0.5" BSP. Connect some reinforced hose to it with the last bit some small bore central heating copper pipe.

Pop the pipe into your sump connect your vaccume cleaner to the bit of exhaust pipe which conveniently should be the same inside diameter as the outside diameter of the vac nozzle, switch on, and Bob's your uncle, or auntie as the case may be.

I have a dry sump so the suction nozzle is 0.5" and it empties 8l in 10 seconds!!!

Good tip about brake bleeding by the way I must try that sometime.
