Over the last few weeks my 147 has been using quite a lot of oil. Not affecting ride or engine but It does go down a lot. Put 2l in when I bought it 5 weeks ago, it went down, then put 2l in about 3 weeks ago, went down again after a 120 mile round trip to York and then added another 2 last Sunday, and the oil light has just come on again (only when accelerating, braking and hard turns, lol) Been checking the dipstick religiously, it has hardly gone up at all. Like I said engine runs sweet as a nut, and there aren't any leaks, or oil anywhere in the engine bay, nor is it churning out any blue ish smoke, where is all the oil going? I am going to buy a big 5l Bottle and oil filter for next week and do a drain and change, just wanted a heads up for what this could be before I waste my money! It is an '06 147 1.6 Turismo (105). Thanks in advance!

some oil usage is normal, my 147 drank roughly 1 litre over 1000-1300 miles, how much are you driving

also, running on oil below the min mark on the stick is quite risky, these engines will suffer conrod bearing damage, which will result in it throwing a rod if not handled

from the sound of it your car is using waaaaaaay too much oil though, if you have any warranty/right of return id suggest looking into that, 6 litres gone in 5 weeks means either you drive a LOT, or something is about to explode

I think I've managed to work out the problem. Paired with the fact it's the 105 edition, I just checked the oil filter and it's as rusty as nail from the 1800s, I don't think it's been changed in a long time! Because it's the 105 it revs High on the motorway, about 3.5k-4k at 80mph, which I know is common for the 1.6s, and paired with the fact it's not had an oil filter change and full drain and fill I think it's just using it up for fun, I do a 50 mile round motorway trip once a week, and it always seems to flare up after that... I've just ordered a big 5l Bottle and filter for this weekend. We'll remove the sump.and check for any leakage but like I said, over the last 5/6 weeks there hasn't been a drip. Will just avoid the motorway, don't have any need to go on it really as the once per week route I take can be taken in the same time via the A roads! Also, I know it's pretty normal like I mentioned before with the rev range, I don't like taking it past 80 on the motorway anyway as the rpm just sounds uncomfortable!

Shoot the previous owner

You just got the car?
Did you not check it over before buying?

It may be the oil and filter haven't been changed for a while. Nice having unfiltered oil going through the engine. I wonder what state the sump plug and sump threads are in.

Hopefully it will be ok but the oil light coming on is never a good thing. It sounds like it was that low on oil it started pumping air.

I really hope things will be ok and I hope you'll forgive my suggestion that you entitle the thread 'how not to buy an Alfa'.:disappointed:

Ha! Thanks, actually we did a really thorough examination, actually took jacks and jacked it up zero rust underneath and no sign of oil at all, just hadn't got round to doing the filter yet. We took it for a good drive, tested the suspension and the lot. When checking service history there hadn't been any advisories on it's last MOT in February and had 4 new tires put on a month before we bought it. I think it just hasn't been used to the milsage, first owner took it to 110k (2006-2015), second owner took it from 110k to 118k, and there is less information on what the second owner did/had done. It's service book has a service stamp every single 12k miles from new and plenty of information to give us the go ahead and buy it. Ferdi my local Alfa specialist said it's sound for the mileage it has done. Actually oredering new springs, brake discs and calipers and 8x new Spark plugs very soon. So I don't think I quite fit into the 'how not to buy an Alfa' threat quite yet although it did give me a chuckle. Will be updating on this thread in regards to process anyway, just incase anyone else is in the same boat and needs a solution/suggestions!

Oh, ok. It won't have any nasty surprises other than the oil then. At least that's good.

If it's burning a lot of oil, the inside of the exhaust goes really black. I know it's black anyway but it's like a different kind of black- kind of like a bad JTS.
Did that make sense or only in my head?

Think I'd best finish there. Clearly I have heat stroke or something.

Hahaha, nah I get what you mean, yeah this heat is pretty surreal! Checked the exhaust, everything as should be, no 'off' Black and it hasn't been burning oil either as since getting the car, it hasn't put out one single poot of smoke, at all! I'm sure all will prevail this weekend!

How much oil is the car using in relation to distance driven? One litre per 1000 miles is normal. It does sound however as though you are using considerably more than this. Bear in mind that the engine holds around 4.3 litres when on the max mark, so if you've already put in more than 6 litres, you've given it an oil change and a bit more...

If you have seen the oil pressure warning, this is very bad - chances are some damage to the crank bearings will already have occurred, especially given the normal wear that would be consistent with the high mileage.

In all probability, this engine is burning the oil due to major internal problems; I've seen it before countless times with these engines. I would suggest that before doing anything else, you should remove and inspect the spark plugs - this should confirm where the oil is going. Post a picture of them if you can.

That is not how it works, all the contamination of the miles driven stays in the oil, rather then gets taken out.
Well, of course; it was a kind of tongue-in-cheek remark to communicate to the OP the severity of the oil consumption. I probably should have used a smiley... :rotate:

Fair enough, i do encounter some people in real life who think it is a valid line of thought though, so thats why i reacted. Just look at how black oil can be after 6k-10k miles compared to new, and imagine running all the same dirt + new buildup for another 10-20K :weeping:

Keep us updated about oil consumption. I think it may be a mollycoddled car which has been prevented from bedding in the engine.

Now it's on 120k the consumption should be going down- not up which suggests previous mobile chicane owners to me.

I've had cars which needed driving properly to reduce the oil consumption.

Hey guys, quick update. This Saturday just gone, drained all oil out, (all 2l), changed the filter to an official one, put 4l of Selenia 20k 10w40 in and 0.4l of oil additive to try and help with consumption. Also did aor filter and pollen filter while we were at it as we bought a service kit. Running very smoothly, the tick has rediced slightly, Although I'm starting to believe it could be a hydraulic lifter (I don't have a variator). Checked dipstick everyday since, same amount so fingers crossed. Just going to keep a close eye on it!

I would at the very least contact a local alfa specialist and ask them the likelihood this did any harm, from what i know running the oil below the min mark on the dipstick will damage the big end bearings on the conrods, resulting in the engine throwing a rod sooner or later. From the story so far, id suspect the bottom end has already sustained some damage.

Hey guys, quick update, I just drained all oil out (all 2l) This weekend and refilled with 4l of Selenia 20k 10w40 and 0.4l of oil additive to try and help with consumption and or any leaks. Also did the oil filter, air filter and pollen filter. Running very smoothly and the engine tick has reduced slightly. Been checking the dipstick everyday since and it hasn't gone down yet. Still belive It could be a hydraulic lifter as I don't have a variator. Will keep you all upated, I don't think my last post worked as the signal at the job I'm on is Rubbish!

With only 2L of oil being in the sump pre-swap, i would at the very least consult with an alfa specialist you trust as to whether that could have caused bearing damage. If the big end bearings are damaged the engine might self destruct soon, and while a bearing swap sucks, an engine swap sucks even more.

Yeah I'm going to see how far this load gets me, it's the first full drain and fill + filter since I bought her. Also doing Spark plugs soon too. Will see how it goes, if the issues comes back within the next thousand miles then I'll take her up to Ferdi's iand see what he says, he was great with my belt and Waterpump change!

If the oil filter is rusty, then the oil has not been changed for a very long time, even if the miles are not being covered, short runs do more damage to the oil than long runs.

I suspected a lack of oil change on our 1.6 147 when we bought it, oil consumption was very much like you describe. Its my belief that an engine running on old, incorrect or cheap oil is false economy. If the previous owner had oil usage increasing, they may well have just dumped cheap oil in which would treat the symptom but not the cause.

Since changing the oil in our 147 a couple of times and using quality oil, the consumption is now greatly improved, about .5ltr every 1500 miles.

I doubt anyone can tell if there is any bottom end damage, a mechanical oil pressure gauge may give an indication, but only a strip down would be conclusive.

Make sure you swap for OEM quality NGK plugs - Alfaworkshop sell them, and if you can stretch, the platinum tipped ones - about £3-4 more each, but rated for 60k miles, rather than 30k.

I wouldn't be worrying about bearings etc unless you are hearing knocking noises and if they were going to knock they would have been doing that already.
For info the difference between max and min on the dipstick is 1 litre.
