Peugeot 107 oil consumption

[Paulprior]

My daughters 107 uses a lot of oil, I haven’t actually measured it but at least 1lper thousand miles, it doesn’t smoke and doesn’t leak, any ideas ??

[steveo3002]

well known for it

can try cleaning the pcv valve and what oil are you running 5/40 or 10/40 should help a little , been running 10/40 in my aygo with the same engine

Common complaint once the oil control rings carbon/gum up lack of oil changes etc its not reversible without an engine rebuild , common on many engine designs of recent years not helped by ever decresing rings sizes/thickness ring tension etc and low friction obsession by manufacturers , like mentioned already try 5/40

[Paulprior]

Ok, but if it’s the oil ring on the piston gummed up and not sealing would I not see blue smoke from the exhaust ??

[steveo3002]

will eventually smoke ...they all use a fair bit , consider it normal and make sure its topped off often before it runs dry

[Paulprior]

I suspect it’s using more than a lot, I will ask her to measure to see how much it uses

Not initially no because its over hundreds of miles it can hang/stay at this consumption without getting worse if maintenance is adhered to and not continually run low on oil IME the Prince PSA engine fitted to BMW Mini's Citroen/Peugeot is very similar in this respect for example

[steveo3002]

they recommend 0/20 for some of these ...you can use 5/30 , 5/40 , 10/40 in them ...the thicker the oil the slower it will use it , all those grades ok for uk winters

mine probably used near 1ltr per 1000miles on 0/20...probably quarter that on 10/40

they have short piston skirts and low tension rings to boost economy ...and a good chance previous owners ran it low and made things worse

Agree with this ^

Ok, I see I shouldn’t spend too much time and money exploring this, the car has done about 130k miles and has not been treated well, I usually check the level when she pops around and it’s normally at the bottom of the scale, I will check the pcv valve though
Thanks all for the info

Not making a suggestion, just asking those better informed than me.

Has no-one invented/trialled anything that can "un-gum" rings by now?

Perhaps along the lines of leave it in overnight, turn the engine over to clear it from the C/C before refitting plugs etc.

some people claim success with a soak with seafoam /marvel mystery oil /magic potion over a few days , or better oil and harder driving may loosen them...or not

Leave it be but keep it topped up.
Family Aygo never got checked only when i laid eyes on it, hence it ran low on oil which of course caused extra wear and made it worse, however they are tough little things, all i'd do is keep it topped up plus a new oil filter now and again and it'll probably run for years yet.

Its hard to drill into some of the youngsters that even if they do nothing else other than keep the oil and coolants topped up their ccars will last years longer.

^^^ Wot 'e said.

I once did an MOT/retest for a family friend's son, the oil filter had collapsed & the oil was like tar.

He had had the car 7 years & had never even opened the bonnet or sent it for a service.

My Son & His partner have junked a bike & car due to NEVER checking oil/fluids even though I have told them dozens of times. I am 100% convinced they still don't to this day.

Use 20/50 classic car oil and run it into the ground

Don't do this !

OK its a Diesel, but when i bought the current Prado with some 80k miles on it it would darken the engine oil quite quickly, i've run the 3.0 litre 4 pot Toyota Diesel in various 4x4's since the early 90's and all have managed to keep the engine oil clean for up to 1000 miles after changing.
The Prado had a good Toyota MDSH, but obviously with normal engine oils, not i would have thought specific Diesel engine oil.
Note, these engines can suffer from blow by at the injector seats, so something one always keeps in mind.

As an experiment bought some 10w40 EXOL Diesel Oil and gave the engine a few oil changes in short order, this was in the hope the increased detergent qualities of Diesel specificv oil would help clean things up, each time the oil was staying cleaner, by the time i'd been through that 20 litre drum the oil was getting on for 1000 miles again before turning dark.
Been using full synth 5w40 Diesel oil of whatever good brand is on offer ever since, if anything the cleanliness keeps gets better, you can see the oil pick up strainer through the drain hole on these and it looks like new.

Not suggesting this is the magic answer to your question, but can't see using a Diesel oil of reasonable multigrade (not straight 30) in a fairly standard petrol engine would do any harm, especially if changing within say 2/3000 miles, i wouldn't be averse to trying this out on a petrol engine suspected of having gummed up rings.

I cleaned the PCV valve with carb cleaner and it made a huge differance to oil consumption but now its back to how it was before so i figured i would get a new valve, but i dont see any available for the 107 although there are some generic ones available from China that look the same, any thoughts on where to get one ??

Have you looked on servicebox for the part you need?

Another simple thing to check is the oil brand. I had an old merc that didn't use a drop running Petronas or Mobil 1, but used some when running the same grade of Triple QX.
