I just changed the oil in my 500R and noticed that after draining it and cleaning out the centrifugal filter, I hit close to the "max mark on the dipstick after only 1.5 liters of oil. I even ran the engine for about 5 minutes and then let it sit for about 30 minutes before checking it again. I'm 99% sure the oil capacity is 2.5 liters, and can't imagine an entire liter stayed in the engine after draining it. Can someone tell me if I'm reading my dipstick correctly, and that the line just before the word max is indeed the max oil mark? I'm assuming the other line farther up the stick doesn't have anything to do with the oil level. I drew a red line at the current oil level after 1.5 liters.
Technical Oil change only took 1.5 liters?

Can we see the top of the stick?
Indeed oil capacity is 2.5 ltrs.
You're reading the dipstick correctly by the way.

Is it possible the tube the dipstick goes in has slipped lower than it should be allowing the dipstick to go further in than it should?
Or someone has put a dipstick from another engine in car.
Solution for now is put another litre in then mark dipstick where correct level is .

Hi. Have you been able to measure how much came out of the vehicle, or is it now too late?

The 500 engine is fitted with an oil level sensor and will bring the vehicle to a halt if the engine oil level is low so the engine is not damaged. I have experienced this with the dip stick showing oil just a small amount below the full mark. Always fill a 500 to the top of the dip stick full mark.
Wow that was advanced design in 1957 how does it work?
I think that CotswoldTony may be on the wrong 500 site.
The old 500 just about got an oil pressure sensor fitted.
No mod cons here.
I would be very careful about just putting another 1litre in. Don't run it with too much oil as you will cause all sorts of problem.
The 500 doesn't have a dipstick tube. The dipstick sits in the hole in the crankcase.
Perhaps you have the wrong dipstick? maybe too long?
Unless anyone else beats me too it I will measure my one when I go into the garage later.

my money is on the wrong dipstick
Oh nicely done Sir.
That is one clean engine plus good pics.
My Dispstick measures 150mm/6" from the shoulder of the rubber to the maximum limit.
The shoulder of the rubber being where it sits against the engine case? I'm measuring 7" on mine.
Ok troops listen up!
Elsewhere on this forum is posted;
Tin sump and alloy sump have different capacities.
Tin sump just over 3 us pints , that is 1.5 litres to Europe and UK. Making sense now.
Alloy sump holds much more around 3 litres mentioned
That's very little oil , change it regularly.

I also have the steel sump, but going by the Fiat 126 Haynes manual it should still have a 2.6 liter capacity for the 126A engine. That unlabeled mark on my dipstick is at exactly 6". I'm guessing I don't have the standard dipstick (looking on a few websites, the handle of mine looks like the giardiniera dipstick with the rubber piece off a 500R dipstick?) and the previous owner made a mark at the correct height?
If you have a mark at 6" from the shoulder that sits in the engine, then as long as the oil is at that point then you should have the right amount in there
Can't get at my Haynes just now but the standard sump is definitely more than 1.5 litres.....2.5 I think, which is proportionately more than most four cylinder engines that I have owned.
It might be a custom dipstick where it has either slipped at the collar point or been deliberately modified there. Either way, that additional slot cut might be meant to be a new "full" point.

Gentlemen, according to the 'pukka' 'book of words' the sump capacity for the 'tin' sump on a 500 is as follows:----During oil-change:--1.54qts (Imperial)--1.85qts (U.S)--1.75Lt. From dry:--1.85qts (imperial)--2.22qts (U.S.). So, as you can see, you get approximately 1/2 pint left in the engine during oil changes. As far as I can see, no 'factory' sump will accept 2,5 litres---the SMALLEST of the Alloy sumps take 3.5 litres. DO NOT try and put 2.5 litres into a 'tin' sump---the crank-shaft will dip into it and start causing all sorts of (probably quite expensive) problems.
