Best oil extractor?

[BlackC55]

Make sure your car is level. if not, use a jack to level it out.

Its says 60c max in those instructions.....

The pipe resting on the wing! Sackable offence in my world.

The engine has to be very hot for it to work properly. Coolant maybe at 80 but the engine oil may still be cool. Take it for a 30 min run to warm it up properly otherwise it will take a very long time to vac the oil out and you will not be evacuating all of the oil either as it will be too thick. Also the oil filter must be completely undone as that holds about 300ML of oil.

I would probably do it again and if you want help with reducing the oil viscosity use an engine flush. A properly hot 642 engine's oil will be extracted in about 4-5 mins.

When filling, put a few litres into the filter hole. The 642 has a tendency to skip teeth on the timing chain after an oil change if the timing chain is worn and the oil filled tensioner is at max.

Thanks buddy.

He is my list of poor defences, excuses and other lessons learned for next time (hopefully this will help some other noobs out in future):

- I did think about the plastic pipe on the wing! But I figured first-time use, the Pela and pipe is as clean as a whilstle and the car was freshly cleaned, so coupled with the bitterly cold temperature, the laziness factor was high. I'll drape a clean microfibre over it next time, I promise

- Total novice time in terms of oil temperature and disparity with the coolant temperature. It wasn't until I'd started extracting the oil that I realised it wasn't anything as like as hot as I would have liked. I'll go for a proper run next time.

- Oil filter and engine cap were fully removed prior to starting the oil removal. I'd picked those points up from several helpful YouTube vids. I note we don't have a sticky How To in the forum section, I'll look to draft one over Christmas. However what I hadn't seen was that around the bottom of the filter bowl, there's a half-inch trough that holds a bit of oil that I should have also sucked up with the Pela. In the dark, I didn't notice it until I started pouring fresh oil down the filter hole (although I read last night somewhere after completing the job, that sucking this oil out would be a good idea). Doing a sump dump would of course also miss this little bit of oil. The other thing I forgot to do was pour around a quarter of a litre of oil down the filler and filter holes after initially draining the oil, and then sucking out that extra half a litre to 'flush' as much old oil out as possible.

- I got 8.5 litres out, just as expected, and put 8.5 litres back in. Before starting I carefully measured water into my new Laser oil measuring jug and accuractely marked 2, 3, 4 and 4.5 litres on the side with a Sharpie; it was reasonably close to the factory marks but certainly not spot on. It was my first time using one of the Merc oil 'cubes', and it was really easy to open the tap and fill the oil measuring jug. Much easier than using the 5L containers that oil comes in.

- I put about 5L down the oil fill hole, then about 2L down the filter hole (at which point it really slowed down taking oil via this route leaving an inch or so of oil in the filter bowl, so I figured that was a good sign), immediately fitted the new Bosch filter, and then put the remaining 1.5L in the oil filler hole.

After a 2 minute quick start, the W212 OM642 E350 old school dipstick showed smack in the middle between MIN and MAX. I'll check it again after another decent run and top up if necessary so the hot oil is just below MAX.
Note: no electronic dipstick on this car.

Thanks for all the help and advice everyone, it's been appreciated.

@OneForTheRoad
Its says 60c max in those bull¢hit instructions

Best not use it in the summertime then

 

[ALFAitalia]

LOL.....C not F.....I think 40.3c is the highest ever UK temp! 60c would be a bit toasty!!

Id factored in the oil temperature

There's a huge saftey factor built in to products like this.
It's probably been tested to 150°-200°.
So 60° is guaranteed not to cause any problems.
Saftey related, scaffolding towers etc. are tested to x10 the safe working weight.
Don't let D of Cs and C of Cs put you off. The same products on sale to the trade may well have a higher spec.

How does the safe working weight help when you fall off

 

[ALFAitalia]

So are you saying that upping the oil temp to 90 or so will let it flow at about three times or more the claimed max flow rate as said but some posters? Seems unlikely to me.....especially as a typical 10w/40 oil (see chart) at 60 is barely any thicker than at 90c!

It's been mentioned like 6 times already. To the point of being boring.

I use 5/30 . This topic is now closed .

No it isnt!!

Would this method work with coffee and biscuits instead of tea

Thats a bit of good solid advice!

I get my oil as warm as it would get in normal usage before pumping it out. It only takes 10 minutes at most to connect everything up and finish the suction process.

You can't sue them for falling off.
But you can if collapses under your weight!

No I don't believe 3 times either, double or perhaps a little more.

I haven't got the figures to hand for 10W40 but the viscosity of a typical 5W40 is 41.9cSt @ 60C and 18.1 cSt @ 90C
