Dealership overfilled the engine oil

Probably a line down the dipstick tube attached to a vacuum pump.

Many dealers do oil changes that way these days.

Yea, about R300 bucks at a car parts shop last time I checked, you get the kits with the oil filter wrench included a bit more pricey.

A nice way of draining the sump, so that you don't get a face full of oil under the car - you can then remove the filter when the sump is empty, which is far more civilized! :D

No man, they will hoist it up on a lift, and just open the drain plug on the oil sump.

I checked the oil yesterday (week after the service) because the invoice said they charged me for 4.5L of castrol gtx and I know it usually takes 5L to the halfway mark on the dip stick.

To my shock I see they have overfilled to about 1CM above the max mark on the dip stick.

My scoob manual indicates 4.5L for a refill. I have put in 5L for the last 10 years. No issues. But this car has a windage tray and the sump can carry the extra oil. My Oil pressure gauge shows the same pressure with 4.5L or 5L (Mobil 1 15w50 PAO)

Different cars have different size sumps, if that is what you are questioning.

All Subaru take 4.5 ;litres, but many other makes will differ from that.

Correct - crankshaft pressure can become critical in an overfilled engine - High Blood Pressure for cars! :)

I only check my oil first thing in the morning, then I know that it's at the correct reading. :)

It is more critical on a car like a Subaru, however, as the Boxer engine, being flat, takes easily an hour for the oil to run back into the sump.

I had a friend completely bugger up his engine on his WRX when they first came to SA.
He was on a long trip and the oil light came on so he stopped and put oil in(3 pints) then 80km later it was still on and he put another 2 pints in, rinse repeat for a few pints and they way he drove it basically things broke badly.
Turns out it was a faulty oil sensor and he had put many more pints in than it needed.

Fortunately it didnt phase him much and he was a wealthy lad, he managed to source a 22B motor from a contact in Japan and his car was a monster after that.

Most people would check the dipstick when filling up. As this allows you to determine the amount of oil to fill.

If anyone fills 2.5L of oil on one trip and does not figure out something is wrong.........

The idiot light is just that.

BTW if the oil pressure light comes on in subaru. The big end bearing is toast.
 
Engine was filled after it was started.The oil was stil in the head and not in the sump.They do this at garages too when filling your car with fuel.I service self and and check everything self.Take photos and return vehicle + lay complaint and branch and head office.
Don't know engine but crank can impact with oil.or oil can spill into intake manifold.Which will be bad for turbo since you don't want carbon or oil in exhaust side of turbine + cat will strike.

I'm not saying overfilling will destroy your engine.I might be bad for it.Also you can always take your own oil and request garage to fill with it.my dad always supplied garage with Duckhams Oil to fill his car with

some say...
too much oil puts pressure on seals etc..

What seals would this be?
The lowest seals in engine are the crank seals.and at the speed the crank is spinning at the oil is flung away .1Cm overfill will never reach crank seals.and even then it will just leak out when engine is switched off.Biggest problem is crank drag and oil in intake.
 
Most oil pumps have a pressure release valve that controls the oil pressure.

That much over filled oil = crank drag and oil cavitation etc, and bent stuff. .

This. Done this before with VW. So instead of R1200 for ****ty oil and R500 for labour you get better oil for R400 and they just charge you R500 changing and for the stamp :p

Yeah they did check the dipstick but it was literally after pulling off the road and after driving pretty fast.
So the oil didnt have time to settle and when they checked the dipstick it looked like it was pretty empty.
I called it school fees :p

The mechanic probably takes your good oil home and tops you up with the schitty stuff :D
 
Took my turbo car for a check. Asked them what wear on tyres and brakes. Couldnt answer. Took it back and pointed out brake discs need to be changed. They agreed to install front brake kit (supplied by me) at no cost. Tells u something doesnt it?
