Oil change, do you know if your car service shop drains or extracts oil from the top ?

You must drive a cheap old car.

All Benz dealers extract oil when it's possible and oil filter is on top.

 

 

That might be applicable to that specific brand model but not "in general" and who specifically said this was for/about Benz vehicles.

You are so funny.

Really you cannot understand that it depends on each car ?

Try something called youtube and you might find many reviews where people check exactly how much oil is extracted compared to drained, and often more oil is extracted than by draining procedure.

 

 

 

 

 

Hey, you never watched the vid did you....You are so funny.....😂

I see another topic you like to do things as cheap as possible, so are you doing this so you can change the oil yourself without using ramps? Because in Thailand the cost is so low the purchase of the gizmo would wouldnt be cost effective, so I am guessing you are not even in Thailand ?

if you are, what places uses these extractors? and dont give the nonsense about having a Benz yourself as that's ridiculous given you penny pinching on a satellite box !

Not all extractors are created equal and I certainly would not base my opinion on the method from one vid found on the internet.

 

Then you have cars that do not have oil filter access from above so they need to be raised and have any engine guards/plastics removed to do the filter so might as well drop the oil via the sump plug whilst its in the air.

Mazda and Ford dealerships use them and I suspect others do as well.

May be by some but not all, in my experience I have never seen that method used in Thailand. I have both those makes and 2 others.

My answer is based upon what Ive seen at the dealerships my previous employer owns.

I have seen my oil drain out of the raised car many times here in Thailand. 

 

I did not know they vacuumed it out though that is interesting. I wonder if it is actually better, extracts more.

In other words, the bean counters in some car dealerships have worked out the time saved in using vacuum extraction in terms of labor costs is more important than the well-being of the car's engine. But wait, there's more. A shorter life means they get to sell more expensive replacement parts and repairs to boot. It will be shorter, because an unknown quantity of used oil gets mixed up with the new oil put in.

My mechanic drains the oil while it is still hot. He changes the oil on my Vios every 5000 km, explaining to me the extra cost is worth it in terms of engine life.

If I ever saw a mechanic using a vacuum extractor, I would withdraw my car, and never go back to that dealership again.

Perhaps that's why Benz servicing costs are 2-3 times that of other makes.

It extracts more in the same way that Doctor Who’s tardis is bigger on the inside than the outside...i.e. fictional.

My Ford dealership doesn't. I've watched them do mine and the replacement plug seal is on the bill.

What part of drain the oil by removing the sump plug (handbook stipulation) do you not understand?

Feel free to quote the model and maintenance paragraph in your rebuttal.

Sorry but it's clearly faster and easier for any mechanic to do it through dipstick hole....

 

 

And they'll of course get the oil filter out through the dipstick hole as well?

 

   There's nothing better than a fully drained oil, old style, and metal pieces at the screw removed.

 

  Unfortunately, do I have to tell them how much to fill in.

Whenever I have a 6 liter container, they usually believe it's okay to fill all in, but the engine only wants 5.5 liters.

 

Not enough oil is as bad as too much oil. 

 

    It's important to let all old oil drain, as the rest usually contains tiny particles from engine wear.

 

   How do you get that out with a stick?
