having a problem with oil consumption on my mk3, seems to be very juicy on oil.
using mfr's recommended - 10w30 but seem to be topping up levels everyother week - there is no leak and no smoke ??
mfr states it should be using 1 litre every 1k miles ??
filter was changed last service and no change
are any other grades of oil better to use ??
any ideas - need some help as being fobbed off as "that is normal for a VVTI"
is it ...
cheers
How old is your 2?
How long has it been using this amount of oil?
How is the car running?
My 01 car with 17k miles on it only needed to be topped up every 6 months and even then it was a tiny amount.
she is a y-reg 2001
has done approx 52k miles and it has been like it for a few months now.
the car is running fine all in all, sometimes is a bit sluggish when i open her up and only occassionaly falters (as if she hold back then goes again) when accelerating.
also when not accelerating or braking - coasting - there is a rattle from underneath but i put that down to the exhaust cover vibrating ....
That rattle is your crank bearing and it is using oil from the excessive wear. It runs sluggish because it isn't performing as it should and its slowly dying.
If you've got any warranty then I would get this looked at properly as it will be a replacement engine very shortly.
Not that I like to cause a panic, but I'd recommend a search on "pre cats" or "precat" (and similar variations)..
How often is "often" btw, with the topping up (in terms of miles covered)?
The hesitation could just be the MAF needing cleaning, or it could be a sign of contaminated O2 sensors (though I'd expect the latter to be quite likely to throw a CEL).
The rattle probably is the exhaust heatshield (though not necessarily, it's perilously difficult to diagnose noises over the interweb s:) :) s:) )

Sounds as if the car may be suffering precat failure. when it happend to my last mr2, it was so extreme that it used 4.5 litres of oil in 3 days and at that it didn't seem that smokey till you put your foot down.
Rather than panic you, the quickest way to confirm things either way is to remove your o2 sensors from your manifold, shine a torch into the hole and see if the precatalyst material looks intact.
if you need more info with regards to this, see GSB's "Precat removal" for a more detailed explanation.

cheers for all the advice - appreciate your help with this ...
at the moment i am putting in 2-3 litres every 2 weeks, i do between 30-40 miles a day so well under the mfr spec
i may book her in the garage for a check-up this week as the warranty expired in october too so better to be safe than sorry s:( :( s:(

Don't use that grade, it's way too thin. Even a 10w40 is too thin. You should be using a 10w50.
Also, don't forget that while synthetic oil offers the best protection, it doesn't "smoke" and so you can't tell when you're burning oil.
Try Mobil 1 Supersyn 10w50
TTE use 10w 45

Incidentally I run 0W-40 and don't burn any oil..
But on the original topic - it doesn't sound healthy at all, and does sound very much like the engine is starting it's death throes..
BTW There is a difference between crank bearing failure and pre-cat breakdown. This definately has the hallmarks for a big end rattle caused by a bearing failure.
Hey, pleased to see you over here, Millsey - welcome to the mr2roc!
Unfortunately, it's not looking too good for your poor baby! s:( :( s:(

I'm unclear as to why big end wear should result in high oil consumption. I guess if it were main bearing wear, the movement in the journals could allow oil to escape through the seals, but in that case I would expect there to be a significant oil drip under the car.
Surely, if the oil is disappearing, it must either be getting burnt, or it's leaking out.
cheers for all the advice guys - appreciate your help with this.
found out what the rattle was - the heatsheild was loose on one side so thats one problem down anyway s:D :D s:D
can't get the car into the garage till after xmas now, so will drain oil and use Mobil 1 Supersyn 10w50 instead to see if this solves the rapid consumption ..... i'll try all options before i let the garage charge me an extortinate amount of money s:roll: :roll: s:roll:
thanks again s:D :D s:D

The symptoms you describe are exactly the way Lynn's car is behaving. Its getting through about half a litre every 800 miles or so but seems to not be getting any worse. I'm very interested to hear if the oil makes any difference. I must find time to confirm that the rattle is the her heatshield too!
Mind, just to be on the safe side we have taken out a Toyota warrantee for two years! ...just in case!
Cheers

Hi Millsey,
Just to add to whats been said already...
My car had the symptoms you discribe - a rapid use of oil, but no noticible performance loss.
When they did the consumption test, after 150 miles I rang up informing them, if I made the return journey my sump would be dry and so topped it up - it was ment to be 1,000 useable test ! doh !
Anyway - turns out to be the oval bore syndrome the cars have suffered from, so I had a complete engine rebuild, 1 month previous had, had the main cat and manifold (pre cats) replaced as the precats had fallen into the main cat and blocked it !
I'm afraid you may be looking at needing a new engine, unless you have a good contract with an oil company, so you can continue pumping oil and petrol in her.
I really hope you get it sorted FOC, but with the age and also the lack of warranty since October, it dosen't look good....
If you can get in any sooner - I would as the longer you leave it the less likely you are of them looking at the engine as a good will gesture.
Q: do you have a full Toyota Service History, within intervals and has it all been done at Official Toyota Dealerships ? if so they may do it as it's under 5 years and 60k.... good luck and get dialing now.
Best wishes

This has happend to me and I've bought a new engine though I still need to know how and why it happened. So I don't do it again. Also when I get my car back. would you advise to pre gut the cat even if the car is under warranty??

Are you saying Toyota made you pay for a new engine even though it is still under warranty???? s:shock: :shock: s:shock:
I don't want to go through this again please its a too long of a story and I it causing me to cry again s:oops: :oops: s:oops: s:cry: :cry: s:cry: s:cry: :cry: s:cry: s:cry: :cry: s:cry:

hey mate
just in answer to your question - she has a full Toyota Service History (thank god s:) :) s:) ) so i am hoping all is not lost .....
i wonder if i played the "but i'm female" line then they may show some sympathy .............. s:?: :?: s:?:
no i didn't think so either s:( :( s:(
If you get no luck i'd pop into your local trading standards and see what they have to say. You have a reasonable expectation that your engine won't die after only 4 years.
If you have full Toyota Service history - you may be in luck and they may be prepared to do it as a good will gesture.
The only issue is, they may say, until they have opened it up and had an inspector, that you may be liable for the cost, IF it isn't a know problem.
I was lucky, basically I said either Toyota or the Extended Warranty people will pay, so I let them argue it out, who paid... but unfortunately you are not in this position.
Toyota are pretty good and it is a known problem, so best of luck getting it sorted - but please do get it in ASAP so the ball can be started rolling so to speak.
Best wishes

I guess that it might be of great help to Millsey, if someone can recommend a Toyota dealer, somewhere in the South Bucks/Thames Valley area, who is known to be knowledgable, and sympathetic, of the pre-cat failure problem.
Hi i went to toyota to ask why my car was using alot of oil about a litre a month doing about 800 miles, and they told me that it was designed to use more oil to save the engine. They checked for oil leaks etc and came back ok. It doesnt smoke or run bad so dont really know what it is anyone got any suggestions?

Must be something wrong with mine as its doesn't use any oil at all s:? :? s:?
Quote from: "mrS dan"designed to use more oil
Gotta love their explanations s:lol: :lol: s:lol:
My Spyder has 50,000 miles on it and uses or leaks no oil. But my oil fill cap recommends 5W30.
