1.6 Blue HDi 100 Engine appear to be burning oil

[kingy1912]

Hi all,

Looking for some advice on oil burning on the blue hdi 100 engine if anyone knows. Turbo was blowing oil and as a result was replaced with a brand new mitsubishi one from citroen and fitted as per the citroen procedure. It has appeared to solve the issues of no power or very sluggish power and seems to be running very very well (touch hairy wood). 

However since the turbo was changed it appears to be burning oil at the rate of roughly 1 litre every 3 1/2 to 4 thousand miles. Obviously you would expect it not to be the brand new turbo as it has been doing it almost since or at least i noticed it almost since the new one was fitted. It has probably been masked to an extent by the oil coming from the turbo seals.

Anyway i pulled all the hoses and checked for oil and there appears to be nothing other than a light film of it on the hose going in to the intercooler. I also checked inside the intercooler which was brand new replaced with turbo and its still clean. You can clearly see the silvery colour of the metal and nothing sticking to it.

This leads me to the conclusion that it probably is just simply burning more oil??? It is a taxi and has been serviced regularly and well looked after but it has done 254 thousand miles. I've spent 3k on it in the last 4 months so hoping not to spend anymore for a little while. The garage says from new you can expect a .6 litre usage within tolerance and from brand new between services it usually was using 1.5 litres for top up any way. However this additional usage makes me wonder what is normal for high milage on these engines if anyone knows and how much usage is too much and points to a more serious issue.

There is no funny smells from the exhaust, no smoke, no other leaks anywhere, power feels good, engine is still accelerating smoothly and fuel consumption is bang on as usual at between 55.3 and 56.8 miles to the gallon.

Any help or advice here would be appreciated

Thanks

When they did the turbo what oil did the put in - have you tried changing it to the correct oil?

At that milage i would not worry too much about the amount its burning it not that much at all.

Have you tried adding Millers or similar?I was thinking of sticking piston rings.

Hi there,

Thanks for replying. The car is serviced a a honda main dealer mainly because the service manger there used to be my service manager at my local Citroen garage before he moved. The service kit is ordered direct from their group Citroen dealership so everything is Citroen. When the turbo was changed the engine was flushed and refilled with total ineos 0w30. Every oil change up to this point other than top ups because it is hard to get have been done with total. Even at top up though I use magnatec stop start 0w30 which is C2 not C1 as I seen to only be able to get C1 from Citroen. We are also just about to bring oil change intervals in on it.

Because of your milage you could try 5w30 total or equivalent to see if it helps with the burning of the oil or even a low saps 5w40 oil that meets your spec. All you need is the spec for a 1.6hdi with dpf the 0w30 specified for yours is more to do with fuel consumption. Oils are getting thinner and thinner to help with fuel consumption and emissions. 

My advice is defo to try a slightly thicker oil, if it doesn't work you can always go back to 0w30 and put up with the oil use.

Its a possibility i suppose but considering im not getting any other issues with the engine i dont think it is a problem. I will mention to the garage and see what they recommend but last time i asked about additive they were not keen on adding anything. Also when my service manager spoke to the citroen manager they seemed to be not keen on the idea either.

I was using millers oils ecomax diesel treatment for a while and to be honest i feel all my issues got worse after i used this. I had issues at the time which i think was the turbo in hindsight but at that time i put down to the internals needing a bit of TLC. So i added the ecomax diesel over 30 tanks of diesel which for me is not really that long as i use about two tanks a week. During that period my turbo got worse and the oil consumption which was laid off as the turbo also got worse. Now the turbo has been replaced the oil consumption is about half that before the turbo was replaced. i am still concerned that the ecomax may have some how disagreed with the engine not sure if the higher cetane rating has burned something up in the engine.

Any way i stopped using the ecomax when i thought it was causing problems and my oil burning issue has stabilised at 2 litres every 8 thousand miles or so. However the last 1000 miles it has not burned any which is very unusual. I have a 2010 berlingo with the DV6 engine which is the same as the blue 100 i believe it is just the top end add ons that are different in both. This has 325K on it and was my taxi before the 2016 model this burns very little oil and usual dont even need a top up between services. However it does go through cycles of burning oil then burning nothing which is also unusual my mind set and thinking on the 2016 model is based on the experience of the 2010 model. As a result i was kind of hoping that it was a cycle from when it started to burn beyond the 1.5 litres between services which is now has around 22-25k ago. The old one used to burn oil over one or two service intervals so about 10-20k. Im clutching at straws here but thinking maybe its the same as the old one and its gonna stop for a while maybe im just fulla s**t lolololol.

Im just going to need to keep an eye on it and see how it goes i cant really afford to be having strip downs done after what i have already spent on it. The garage did say that they felt it was not a big deal and i was a bit paranoid about it but i like to keep on top of s**t before it becomes fountains of the stuff. Certainly the car is not doing anything strange of has lights on so im assuming anything that is happening certainly for now is within tolerances

Hi Polar thanks for the advice. I spoke to the garage about this and they were not keen on switching oils since if it goes belly up its my living. it still has two years of finance on it so really need to keep going for at least those two other years. Like i said before im not really getting any problems just this oil burning problem other than that the car is actually running very well for its mileage.

Not really too sure what to do as my first thought was exactly what you have mentioned but not sure on the implications for the oil pump etc if the oil is a bit thicker. I know when i first serviced it they gave me the choice of 0w30 or 5w30 the 0w30 tending to be more for the stop start model but i decided to go with it thinking it was not a big deal apart from it being about £15 a can more expensive.

I would be interested in hearing if anyone with the same engine has done the higher mileage to see if they have the same issue?? My main concern with the burning of the oil is the cost of the stuff as the total quartz ineos from the garage is about £50 a can inc vat and thats with my discount added. He did say if i was using more he would get a better discount on it but its probably only gonna be a few quid.

Also with the increased oil burning i expect more particulate to be produced and thus more regeneration cycles happening as a result i may need another DPF fitted sooner than the last one which was done at 220K because it was filled with ash. At £800 quid supplied and fitted its not cheap either.

Its a bit worrying your garage does not understand oil

The 1.6hdi engine is an old design now going back to before 2007 and not much has changed re design apart from emissions equipment. 

The 1.6hdi started life on 10w40 semi synthetic oil but they had problems with the engines blowing turbos, partly because the oil was not good enough to reach the service intervals.

They then went to 5w40 synthetic and so on with every emission update the oil changed to 5w30 low saps then 0w30 low saps.

Your engine will easily run on 10w40 semi as long as its changed more often say every 5k 

I dont get why there is so little engineering understanding to what they are actually doing with todays technicians who seem to be space invader players and fitters. Thats my feelings as a retired motor vehicle engineer - but what do i know   

I can understand if they said to you yes go for a thicker oil but have it changed more regularly, mind you your vehicle has a constant oil change system at the moment

@ polar,

Couldn't have put it better myself.

I agree, definitely swap to 5/30, we only use the 0/30 in Euro 6 cars, it really is very thin & you would expect it to be consumed rapidly in a high mile engine.
