Oil question again

Sorry but you are incorrect, some "healthy" (as determined by manufacturer) engines do consume that much. Obviously no healthy engine should leak any oil whatsoever, manufacturers don't normaly have a leak specification...

Indeed, Overlag is talking out of his chuff.

so his little fiesta drinks its WHOLE oil capacity within 4000miles and that's ok? No, its probably been starved at some point and damaged bearings and seals is causing it to burn too much. Or as mrLOL said, it may well have oil that's too thin.

Engines are not made to burn oil at this rate, and if they do there is a fault or they are worn out and should be fixed. Just because the manufacture says its within normal limits doesn't really make it right.

If you think its ok for a engine with only 4litres of oil to burn 1litre per 1000miles you're crazy!
 
RX-8 are they all broken?

Never had an issue with thinking the fiesta has an issue, but saying all new cars which drink 1ltr per 1k are broken is wrong, i also never said i think its ok or right, its just how some engines are.

My CTR burns at about the same rate too. and capacity is just under 5L IIRC. The whole of the CTRO forum must have borken VTECZ y0.

RX8 and bmws are renowned for doing it

fiestas arent. Theres a difference

the fact that this has co-incided with him changing his oil to a different grades seems too much to be a co-incidence for me.

VTEC is different because it uses oil to run the VTEC system which adds more possibility of leaks into the combustion chambers.



we are talking about a simple 16V I4 here, not a VTEC, or wan-kel(lol word filter) engine.

Indeed, not got a problem with that but point raised was in answer to this:

1000 miles/litre on many modern cars? so in other words i cant do more than 4700miles before running out of oil and needing another service?

utter tosh really Maybe for a 20year old banger with old seals, but a modern car will not burn that much oil unless its broken (or a super car maybe?)

He says Modern engines will not burn that much oil unless broken, this statement is incorrect, as we know many new engines are designed to burn oil.

VTEC has no reason to introduce more oil to the CC than any other engine. Its simply the nature of high specific output engines to consume more oil as the operating range of all the components is wider and things can only be built to a certain tolerance...

Or maybe Im wrong and you pick up VTEC up from the same shelf as 2 stroke? :p

i thought VTEC's High lift cam setting was activated by a hydraulic type system which uses the engine oil? and this is where extra loss can occur.

But anyway way off topic, and the OP needs to get his little Fiesta checked out.

Its a sealed system within the valvetrain, any leakage would find its way to the sump like the valvetrain oil from the cams.
 
Hi guys,

Thanks for the responses.

I checked the car today and the engine is VERY clean, I cannot see any oil marks/residue etc like people have said.

What I did notice is that the air intake was not slotted properly onto the front of the car, could this cause the issue

Also the yellow radiator fan never span when starting up, should these run all the time, or is it only when the engine reaches a certain level

Thanks
 
Sell it and buy another one. Not worth messing around with a weird issue like this on a car as easy to replace as a fiesta.
 
Hi guys

It went to our local fully fitted garage today.

Gave it a full going over and cannot find anything wrong. No leaks, its not burning it. The valves and piston rings are fine, so im none to the wiser than before.

Asked me to keep an eye on it and if it continues let them them know again, guess I'm just always going to have a thirsty car;\
 
Yup Renault say for the Renault Sports that 1000/1l is within spec. I've done 2k in mine now and it's not burnt anything thankfully.

but at 1 litre per 1k I'd probably just learn to live with it depending how big your mileage is.

It won't spin until the engine reaches a certain temperature. If you're worried about it, let the engine idle for 5-10 minutes, the temperature gauge will go up, when it reaches a certain point you will hear it kick in, it's probably quite noisy.

On a related note, does it matter if you put too much oil in? Will it just go to the sump/be wasted?
