Trying To Avoid 1.6HDI Turbo Failure

[uncle buck]

@ Eddie,

Aye you do need a sense of humor and you want your bumps felt for buying that in the first place.

The low saps oil is used because of DPF's if you haven't got one you don't need use it. The oil specified for modern TD's is a long service interval oil, so you are completely wasting your money buying it if you are changing it regularly.

5w 40 fully synthetic from ECP £12.50 online, change it every 6k or so no problems.

Been running my Laguna on cheap none big brand oil for years, changing it regularly and never had any problems.


Cheers.


9HX = Non FAP.....cheap oil for you

[Eddie Nuff]

I never said I bought the proper stuff, certainly not at those prices, but that it's the proper oil for the engine.

[uncle buck]

Glad to hear it.....

Aye it's the proper oil for the engine according to what the manufacturer says, but that's based on the service interval they specify and assuming the car is fitted with a DPF.

So with service intervals of 6k or so and no DPF the oil is way over specced for the engine...you see my point



Cheers.

If it doesn't have DPF I would have thought that Comma semi synthetic CF rated at about £13.00 for 5 litres would be OK especially with a 5k oil change, I use it in both of mine.

Don't put semi in these Peter. . Dpf or not. Fully only. But not semi!!!

There's low saps fully synthetic and ordinary. I think people ARE making just that mistake and putting semi in. And because of the design where almost half a litre of old stuff is ALWAYS left in the two oil type don't mix and there's your gunge.

your asking for trouble putting semi in.. promise. That's how I see it anyway.

shoot me down if I'm wrong ..

[Peter.N.]

I will take your word for it Paul but the semi is fine in the 8 valve 2.0.

Peter

[citroenxm]

Yes Peter it is.. The 8v is a very different engine to the 1.6 and I use semi in mine.

But the 1.6 was designed for fully and not semi and they don't mix..

[citroenxm]

The 1.6 and 2.0 8v are two VERY different engines indeed and are not related or similar in any way at all..

[uncle buck]

Can I ask where you are getting the information from that Semi & fully synthetic oil don't mix and that the 1.6 was designed to run on only fully synthetic oil?


Cheers.

[citroenxm]

It'sthings I have read.. am I wrong then? As said Iif I'm wrong I'm happy to be knocked down..

I was under the impression the semi and fully don't mix and that's what causes the sludge..

I'd still not put cheap oil in the 1.6 .. I'm happy to learn different uncle..

[uncle buck]

I'm in no way an expert on the subject of oil as it's such a complex and technical topic. I have however done a lot of reading on the subject of engine oil and I know there are a lot of myths and misunderstanding out there.

You can mix fully synthetic oil and semi synthetic oil with no problems, they will mix fine and no sludge will result.

Taken from the Valvoline website:

1.Can you mix different types of motor oil? For example, synthetic and synthetic blend or regular and synthetic? Is this going to cause problems?
Mixing synthetic and conventional oils will not cause any problems. The oils are compatible with each other.


The 1.6 HDI engine.

Citroen recommend TOTAL QUARTZ INEO ECS 5w – 30 for the 1.6 HDI engine and a service interval of 20,000 km (12,500 miles) or 2 years.

If you visit the Total website and use the Lub advisor (link below) you will find that there are 3 different types of Total oil recommended for the 1.6 HDI engine, whether it has a DPF or not.

(scroll down the page to make car / engine selection)


TOTAL QUARTZ INEO ECS 5w-30 (Fully Synthetic, recommended for vehcles with particulate filters)

TOTAL QUARTZ 9000 ENERGY 5w-40 (Fully synthetic for vechiles without particulat filters)

TOTAL QUARTZ 7000 ENERGY 10w-40 (Semi Synthetic, no mention of particulate filters)

You will notice that the 7000 oil is a semi synthetic oil.

Fair enough the Quartz INEO oil is low SAPS, so if your car has a DPF you may choose to use it for that reason, but if the car has no DPF and you intend changing the oil say every 6000 miles instead of the recommended 12,500 miles you are wasting money buying the top spec oil.

Now I'm not saying that a semi syn oil will be as technically advanced as a fully syn but that doesn't really matter if you are changing it more often. Personally I would rather change the oil twice as often with a slightly cheaper oil than leave the dirty expensive oil in the engine. As I mentioned I change the oil in our cars every 6 months regardless of the low mileage we cover.


A good read regarding Extended Oil Change intervals.

I know it’s written by an oil company but it’s probably as close as you are going to get to being unbiased.
Pay no attention to the 3000 mile oil change intervals mentioned, that’s an American thing.



Cheers.

Would a 2011 Berlingo 90bhp van have the dreaded dpf fitted?

Mark

[citroenxm]

Depends! ITs down to the VIN number you have.. Both tunes 92 and 110 can have and might not have..

I think if theres a P in the chassis its yes, otherwise no..

[RichardW]

Mark,

Easy to check - look down between the rad and the engine at the CAT etc - if there is a pipe screwed in half way up, then it has DPF. As yours is 2011 I expect it has - it may however, be the later 8V version of the engine, which seems less prone to turbo problems (but that might just be an age thing....!)

[bxzx16v]

Thanks for the replies, I've not got a berlingo but have been seriously tempted as I miss my dispatch hdi, just not a big lover of anything with a dpf as I don't do much mileage.
