Having subtracted the approximate losses due to leakage, how much oil does your engine use? In the interests of accurate quantification, in my case it's probably almost a small, green teacup-full after a vigorous 400 miles or so. That's a ridiculously high consumption in comparison with modern cars but maybe normal for the 500. My engine was rebuilt about 6,000 miles ago but was not rebored. There is no smell of oil nor any obvious smoke.

Is it important for the teacup to be green? As I don’t have a green one and do I need to specifically buy one to be able to partake in this automotive test? Can you point me in the right direction of a good, reliable supplier of green teacups? If I buy from a supplier in mainland Europe is it likely to prove cheaper than buying in the UK or will BREXIT affect the supply of green ️ ‘s?

Hi Peter, What percentage of the total capacity are you taking as approximate??
How big is your sump?? and are your leaks something like an arterial spray ?? or are you lucky enough to have a dribble or two?? Is your tea cup 100ml or 150ml in capacity (green or not) I have a problem with rebuilds though and a rebore too I just so need to reach 6,000 miles post rebuild that would be fantastic - smelly or not.

Ian.

I think that after Breg-zit the cup will have to be blue, so as someone who would prefer to be any European nationality rather than British at the moment, I'm being atypically ( ) awkward and specifying green. I'm avoiding specifying in millilitres in order to future-proof this posting as I'm thinking that we might have to go back to pants and galleons and I'm certainly not losing that much oil.

I think it is more likely to be a dribble or two, it happens with age I am led to believe?

It's now't that a couple of "Tena-mans" wouldn't sort out. But as for the engine:
I have actually eliminated all leaks although I have to add the caveat that a bit drips from the little cover-plate between the engine and box...it could be either or both leaking.
Apparently a "cup" is about 230ml...not much, and having asked Mr. Google for answers it seems that this is perfectly acceptable....especially for a performance car, which, of course covers Murf.
Incidentally, I'm not in the least bit bothered by the this huge waste of
resources and it won't slow me down.
PS. 6,000 miles is easy; take it just one mile at a time but just keep going.

Only one leak!!!:worship::worship::worship: That would be luxury, mine is not dripping from the cover plate area - yet! I have a tad of a leak from the spin-on filter adaptor (yes it's a mod) and it seems to be weeping along the screw threads from the oil pump area I guess I'll have to remove it and check, but not yet I'm getting some miles in and using a large drip tray (tena - tray) to save the oil
Ian.

Having already topped-up the engine oil for the umpty-oddth time since the last oil change, which was only about 1500 miles ago, I had another look at what the oil consumption should be. The contemporary reports from "The Motor" during the early days of the 126 and when the 500 was current, suggested that anything between 1,000 and 2,000 miles per pint of oil might be expected.

Taking into account the oil loss via leaks, my experience is that is a bit on the high side. So given that the sump starts with 4.5 pints out of my 4 litre (7 pints) container, that leaves me with 2.5 pints. It's hard to be sure because I always seem to be decanting from one half used can of oil to another, but I probably get through at least that remaining 2.5 pints before I cover 6,000 miles; so 2,400 miles per pint.

So now I know why my oil never looks black...I'm constantly diluting it with fresh stuff.:bang:

I have a 3.5 litter pan and today i added 1 liter of oil (Castrol 20w50 mineral) after 1500 km's
Engine had an oil leak from the fuel pump spacer but now i have fix and i have zero leaks (usually this makes me nervous when i see no oil under the car). To be honest i don't think that leak was so big to excuse the oil quantity missing but ofcourse i don't know how much oil was leaking while driving but only when it was static. So stay tuned until my next report.

I think a lot of that oil must have been lost through leakage, but we'll see. But your engine probably is burning a lot of oil (in comparison with modern cars) just like mine...reassuring???

Peter, i think that my consumption is somewere between 300-500 ml/1000 kms. Better than 16 million euro jet engines I am working on that require at list a quart of oil/day. (poor comparison but I like it)

Clearly, the 500 design is more sophisticated.

At 1,500 miles per pint of oil, the consumption is quite normal for the age of the vehicle.The OFFICIAL oil-consumption figure for the classic 'Mini 850' was that 1 quart of oil (almost a litre) consumption over 1,500 miles was perfectly acceptable!
