I took my car in for an MOT this morning,
Shortly after, I get a call to say that my engine has 1litre of excess oil they need to drain before they can start the MOT
He wanted £20 for this to be done.

Am I being ripped off here or is this a genuine issue

thanks in advance

Obviously.

Wouldn't have a maximum level otherwise, would it.

Is it a diesel?? If it is, you might want to think about where the extra has come from

It certainly can be an issue and £20 sounds reasonable to drain (or suck) out the excess.
Maybe car was overfilled with oil last time it was done, or maybe you have fuel making its way into the oil.

its a petrol

service was carried out only a few weeks ago so seems reasonable that too much was put in at the time.

take the invoice for £20 for oil removal back to where it was serviced and ask them to refund it

£20 not a rip off if they have to lift is and drain some out. If they have a suction pump it’s a 5 min job through the dipstick and the pumps are about £30-£60 on eBay

Is oil level checked as part of an MOT?

A message might have come up on the dash.

It's definitely possible. Last summer I had a full service at Porsche, and the first time I took the car out for a drive, I saw a concerning message on the display:



The garage were unable to explain how this had happened, and said that oil delivery into each car is measured by a computer. A representative from the garage came with some Mobil 1 to top up the engine, and then shortly afterward, I got the following message while driving:


(Photo taken by my passenger)

Turns out after a bit of investigation that the oil had been correctly filled during the service, but was being under reported by the level sensor. Now the sensor was working again, it was sensing the excess oil level. So they took the car away, drained it and then refilled it to the correct level. Why they didn't just drain the excess, I don't know.

Engine oil level is nothing to do with MOT.

Ffs.

You have to rev the car, and drive the car on and off the ramp. If something goes pop (and overfilled oil does have a tendency to find it's way out, often hot, in a hurry), the garage doesn't want to be liable.

So they'll tell you.

They don't have to do the MOT. And if I was them I'd be telling the customer too. It won't fail an mot because it has too much oil in. It may fk the car if driven with it.

The customer could come back, take the car away, and either use another garage, if it gets there and another will ignore the dash warning, or take some oil out themself.

If they don't want to, then either it's no mot, or it's oil out, for which a charge is levied.

Common sense. Feel free to try it.

It is not a failure item, it is something they check so they know the car is OK to be run to go through the MOT.

If the oil level is wrong, they can refuse to test it.

Normally that'd be because it was way too low, but being excessively high is a valid reason also.

An MOT tester isn't going to physically check the oil but if a warning flashes up he's probably going to refuse to test it.
Now if all cars had a dipstick it would be so much easier

When doing an MOT they put a thermometer probe down the dipstick tube to measure oil temp for emissions.

Fingers crossed it has just been over filled but definitely something to monitor over the coming weeks.

Some more recent models without dipstick need a complete refresh not just excess drained. I was surprised but a number of techs got caught out by such nonsense.

The other reason is they can then actually be confident of the actual oil in there.

So they check the oil level during the MOT? News to me.
