Using a vacuum pump to change the oil.
Discussion
I picked up one last night.
Strange sticker on the inside of the lid.
and I changed the oil on my SH125.

You guys are missing the point.... You should be using flushing oil as well....
Really? I did this once in the 70's when I had a sticky hydraulic valve lifter, but with modern oils I can't recall any manufacturer listing it as a service requirement, or any dealer ever carrying out a flush. I'm sure if they thought they'd get away with it, they would. And I don't recall seeing flushing oil on the shelves of motor-factors in any quantity.Does anyone do this?

Measure residual oil that just can't be removed using a pump.
Looks like a recipe for ruining an engine. Thank God I removed the plug...
So, verdict (as if we didn't already know. I mean, if it's OK for marine engines....)
Can't see a problem, really. Carry on...
And what of those here who did the same thing and found no oil remaining?Looks like a recipe for ruining an engine. Thank God I removed the plug...

Your test isn't conclusive on the following grounds..
(1) We don't know if you inserted the tube far enough. Did you measure it against the dipstick?
(2) If it doesn't work with that car, it doesn't mean it's ineffective with all cars.

The first time I used my pela 6000 I took the sump plug off when I was finished with it to see how much was left in the sump. It was less than a desert spoons worth.
Any engine I've ripped down for a build has had more oil than that left in the galleries and journals. So I'll not stress over a few cc's left in the sump.
I've been using one for seven years now. Not wrecked an engine yet, oddly enough.

Quite interesting reading this - I've always thought draining must be the way to go as it gets the sump cleaner, but a teaspoon-full left after a vacuum pump can't make any measurable difference to the new oil.
Tough call - flat on back, bouncing wrench and knuckles off a crossmember as the plug starts to turn, dropping burning sump plug into bowl of hot oil, watching the wind blow the dregs of the oil past the bowl and onto the drive.... or £12 to insert and suck, while vertical, clean, and spanner-free. I might try one

I think they're great. I've got one of the round Pela models.
On the other half's Corsa D, the filter is accessible from the engine bay and the vacuum pump means I can do the whole job in about 20 mins and it saves a visit to the garage for the basic servicing.
I've done interim oil changes on the Megane 250 with it (between trackdays) - but I tend to leave the filter change for the yearly service since I'm in a shared parking space and that just takes too much effort to get out.
I actually used it on my Caterham last year since the sump plug was stuck tight and since the space underneath the car was so limited I just couldn't get the leverage needed to loosen it. The filter was reasonably easy to get to, but like everything on a 7, while you might be able to see the part, doesn't mean that you can remove it easily!

So I've just tried my LIDL unit for the first time. I was quite excited about being able to service the car completely from the top so got started as soon as I finished work. I was desperate for it to be a success.
Sadly, it was an unmitigated farce.
In the 30 minutes allowable pump run time, I reckon I extracted about 600 ml of the 3.9l in the sump. I tried loosening the oil filler cap, reapplying it, repositioning the pump, juggling the hoses, lowering the pump, lowering the receptacle, everything.
Now, it may be that I have a baffled sump. I don't think I do, but it's a possibility.
Out of interest when cleaning it up I pumped water and detergent. It managed that reasonably well.
I'm afraid I'm out. In the time I did this I could have got the car in the air, on stands and the plug off. Ironically, I got just as oily faffing about with the hoses as I would with the spanners.
As I say, I really wanted it to work out. I love beating the system.
Sadly, ahm ooot.

That's a shame, usually Lidls tools are fairly reasonable quality. Did you get the oil nice and hot before trying to extract it? Was the pump sucking air through rather than oil?Sadly, it was an unmitigated farce.

Lord only knows what was happening. I tried everything I could think of but it was having none of it. Such a shame. Gassing Station | Home Mechanics | Top of Page | What's New | My Stuff
