Hi there.

I need some help to interpretate the analisys of the used engine oil from my Renault Megane II Break 1.5 Dci from 2007. Diesel engine.

The main reason that i've required this analysis is because this engine in my car and cars from other brands such as Nissan, Dacia and of course Renault came from factory with serious problems in big end bearing shells those parts broke earlier, about 100.000 Km's to 150.000 km's!! In normal conditions as you know this parts live a car life, 400.000 km 's or more. I don't know of wich material this parts are made, can you guys tell me reporting to my oil analysis if there are elements of big end bearing shells in the oil? If those parts are beguning damaged?

Wich material are made the big end bearing shells from Renault Megane engine?

I've requested this analisys to prevent to open the engine and replace the big end bearing shells

I change the oil at 15.000 Km intervals, and the oil i'm using is Castro Edge 5W40.




Many thanks.

I would expect lead and copper to indicate a bearing issue. Copper can also be from an oil cooler.

ok ,you might want to tell us what type of diesel ,if it is biodiesel (15%)then wear is normal .bio diesel is very hard on engine ,gas with ethanol or other oxygenator is also insanely hard on engine (too clean or whiter then white so engine is literally broken apart by the fuel or gas)if you can find non bio diesel?you ll still face issue if your diesel is clean (non bio)why?because now a day we got ultra low sufur diesel this is also hard on engine ,best would be a 0.5% bio diesel.since I highly doubt it exist,the next best is to add a lubricity additive to clean diesel. about 0.5% should be adequate for diesel

I thought the main issue with ULSD was if you had an older mechanical injector pump like the Bosch VP44 on my Cummins? I do add 1 oz TCW3 per gallon of ULSD.

Ensure your air filter is in good working order and sealed properly. This should help with the silicon wear metals are not elevated based on universal averages but determining engine wear based on UOA's is dubious at best.

I am surprised to hear you are experiencing trouble with the Renault 1.5 dci engine. Here our national motorist association(yep it is it,s actual name) just had an article in there magazine about the trouble with modern diesels.

According to them that engine was one of the best, and will most likely give you many trouble free km. The worst is the VAG 2.0 TDI and the PSA/Ford 1.6 diesel.

But it also sounds to me like you use the wrong oil. Here they require a 5w-30 RN720 oil.

Hi shDK,

I don't have any knowledge about other countries but here in Portugal is a very serious problem, so serious that Portuguese Renault and Portuguese Renault dealers recommend changing the 8 big end bearing shells at 100.000 km's or 120.000 km's. And those dealers support all costs if your car did all maintenance there, if not the client has to support it all.

If you check Portugues forums you will see the many sad reports about that. Cars from 60.000 km's to 180.000 km's!!! The engine model is K9K, mine is K9K 732.

Cand you send me the article or the link?

Portuguese Renault recommend Castrol Edge 5W40 for this engine.

Thanks.

Haven't heard of that in Romania, where K9K is omnipresent.
I would try a different oil.

Hi.

I'm not doubting about your report, as said I don't have any knowledge about other countries.

This oil (Castrol) and others like ELF 5W40 are oficialy recommende by Portuguese Renault. That is consentaneous.

In the interval between 100.000 Km's and 120.000 km's, Portuguese Renault and his dealers collect an oil sample and send to a laboratorie in France, then passed a few weeks contact the owner to replace the big end bearing shells.

Thanks.

Guys please, any help here:

I don't know of wich material are made the big end bearing shells, can you guys tell me reporting to my oil analysis if there are elements of big end bearing shells in the oil? If those parts are beguning damaged?

What do you realy think in general about the analisys?

The answer is above.
In your UOA, Cu and Pb are perfectly fine.

JorgeMartins,

As already said, besides the values of Fe, Al and Silicon, your UOA seems normal.

Try the OEM air filter, if you are using other brand, and shorten the OCI to see if the numbers go down a bit.

FWIW, I can confirm what was said about the directives being followed by the Portuguese branch of Renault, and I donīt take too serious what the auto magazines try to sell us, but thatīs another issue.

Regards.

Mm!you arent using bio?then you must be a city driver !your ll need thinner oil .5w40 oil are great oil anytime but when cold.if you do a lot of start and stop city driving .might want to switch to a blend like a 10w30 for big truck .if money isnt an issue you could try shell rotella t6 0w40 or mobil delvac1 le5w30 (all the one i mentionned are all big truck oil).no it doesnt have to be exactly those,they re just a reference for comparision .

Hi yvon_la,

60% city.

My car use Castrol Edge 5W40 it's the Renault recommended oil for this car.

If the air filter is OK and is the OEM recommended, and all the intake system is pristine, maybe shortening the OCI does do the trick, but is just a guess.

"OEM recommended"

"shortening the OCI"

Does yor car have DPF? If not i would use Selenia WR 5w40 in this Megane. It's one of the best common rail engine oil for cars without DPF. And shorten your OCI to 10 k km or 1 year if you are doing alot of short trips. And you really don't need 5w30 in your hot/ moderate climate.

Hi chrisri.

What is DPF?

My car uses Castrol Edge 5W40 not 5W30.

DPF= diesel particulate filter,an emission nonsense,but you probably don't have any in your Megane since you are using Edge 5w40. Some others recommended 5w30 oils and this is why i mention that grade.Stick with Castrol but keep your oil change interval under 10000 km.

yvon_la,
You Know now, In Portugal Renault recommends changing the big end bearing on 1.5dci (Renault, Nissan and Dacia) between 100 and 150k!

If you google it, chectk on foruns or contact Renault stands it's easy to find.

I aint saying the bearing isnt an issue ,but usually oil pressure is the culprit.side note stuff like twin cam and variable ....is fairly new on the diesel world wouldnt surprise me if pressure of oil need to be 5 or 10 psi higher then it used too

Hi there.

I've requested a second engine oil anaisys and I need some help to interpretate it based in the topic domain.



Renault Megane II Break 1.5 Dci, 105 hp from 2007. Diesel engine.

I change the oil at 15.000 Km intervals, and the oil i'm using is Castro Edge 5W30.

Many thanks.

Hi Jorge. I don't know anything about your little diesel but at least in this latest oil sample everything is in line with universal averages. As of last summer Blackstone mentioned averages were based on 10,300 km and you're fairly close to that. That's a good sign.

However, if Renault had some parts with bad metallurgy they may crack and break apart without warning. Oil analysis can't predict when a piece of metal is fatigued and about to break apart. Nor can oil analysis see big pieces, only real small particles.

The silicon does seem to run high in that Renault engine. Universal averages are at 24 ppm and your latest sample is much higher still. Last summer you said you put in a new air filter but make sure all the seals and fittings are properly secured and not letting any extra dust enter. Some people use a little grease around the edges of the air filter box for help in this area. You may not need it, just make sure all plumbing is a good fit.

Sorry I can't be of more help regarding your concerns with the bearings.

Hi Jorge. Is the problem you are concerned about due to bearings just wearing out prematurely as if there's poor lubrication? Or are there parts breaking? You mentioned shells breaking.

Your results show everything to be ok and if you have normal oil pressure I think you're ok right now. I just wondered if you can be more specific about what is happening ( what you're reading about ). Is it bad design, poor lubrication or bad metallurgy? Do you have that info?

Your copper, lead and tin look just fine. I wonder if the problems are gradual or if you are hearing of sudden death because of breakage.

Hi dustyroads.

First of all thanks for your help.

It's about an engine model (in my case it's K9K 732 engine type) that is comon for Renault, Dacia and Nissan. Big end bearing shells broke suddenly in about 100.000 Km's to 150.000 km's.

Portuguese Renault makes an engine oil analysis at around 100,000 Km's in France but only to cars that do maintainence on the brand, that's no my case. If there are more particles in the analysis, Renault replaces the parts with no cost to the customer.

The new engines come now with different big end bearing shells, further strengthened.

It's bad design, poor lubrication, bad metallurgy, etc. Too many stories from customers and by the Renault but is sure what mentioned in the previous paragraph. I put new oil in 15.000Km 15,000.

There are reports of cars with this engine range that never gave problems and there are others who happens to 80.000 km's, 100,000 Km's ...

Do you believe that through this kind of analysis i can't discover any abnormal wear of any engine part?

It's a sudden death.

Hi Jorge, yes you can discover abnormal wear to some extent. Your latest sample looks good. No excess bearing wear noted.

I just meant that if the metal fatigues, cracks and suddenly breaks into pieces, then you may not get any notice. If metal is fatigued, it can break anytime without warning.

I would continue to test the oil, and hopefully you will catch a rise in bearing wear, but I'm not certain that you will. I hope so.

I would ask for guidance from an experienced mechanic, familiar with your engine. Sorry I'm not more helpful.

how much are the new shells, and how much for the oil analysis?

I'd opt to renew the shells anyway they cost peanuts usually, but I don't know if you can get the uprated parts from anyone but Renault. As been said, fatigue doesn't show, and to notice a trend for increased wear you need a lot of analysis.

Thanks again dsutyroads and Jetronic.

Jetronic,

The engine oil analysys and shippment costs are 25 USD

Replacing shells cost in Renault whit all parts an new oil, 530 USD. But the problem is not the money, is that i've some opinions from 2/3 mechanical that open the crankcase and replace shells may lead to future problems that may not otherwise exist.

Tow images with damaged shells:






That doesn't happen to all engines, my idea is too make 3/4 oil analysis and if the values stay normal i'll presume that is nothing wrong with the shells.

Hi CT8.


I've already seen them.

Thanks.

if replacing isn't an option, I'd sell now.

Jetonic,

replacing is an option, but i prefer monitoring the engine oil now. That's what Portuguese Renault is doing. Cars with abnormal parts in oil should replace shells.

Regards.

Dear JorgeMartins,

Regarding those results I wouldnīt be worried. Almost all values are on the average side, and only the silicon is (and it was already) above expected. Try to see if thereīs something wrong with the filter housing/air filter.

I donīt think that, looking at the numbers only, that you have a problem, but and as obvious, a mechanical failure can occur without warning in any engine at any given time, but I will leave that to the psychics. grin

Regards.

Hi Blasar.

I've checkd filter housing/air filter, found nothing.

Do you recommend some kind of air filter or any special measures on that?

Many thanks.

Hi!

Besides all that was already said, my only advice is to choose good quality filters and verify, once more, that the filter housing is tight sealed.

Regards.

one oil analysis at 100k miles isn't monitoring though. you'd need constant oil analysis for that, from fairly new. then the oil analysis cost however becomes equally expensive as the change of the big end shells. the cheapest solution therefor is to replace the bearing shells as a matter of course and be done with it. the next best solution is to sell the car before you get any symptoms, but you'll loose money that way over the bearing shell change.

changing big end bearing shells requires only for the sump to be dropped, can't see how you'll introduce new problems to the engine that way, unless the work done is sub standard. and if you do it yourself, the cost will be much closer to $100. Not worth taking any chance, imo.

Hi.

I think that monitoring engine oil is always a good option.

Thanks for your opinion Jetronic.

If your bearings get to where they're looking like the ones in the picture, you'll see a LOT more copper and lead in your oil analysis.

New bearings cost $500 usd for this engine? Does that include installation labor? That seems really high for parts alone.

The bearings are not hard to change so long as the oil pan can be removed easily, i.e., there are not major subassemblies in the way such as driveshafts or such. (I had an Acura/Honda Legend once and the driveshafts went through the oil pan!)

Brons2.

Yes the price is hight, but real and includes installation labor.

Which materials are composed the shells?

Many thanks.

The soft material on the inside of the bearing shell is lead and copper, if it's a tri-metal bearing, which yours appear to be.

Some engines, especially in Fords, now use bi-metal bearings with aluminum being the main ingredient in the bearing surface.

I owned Renault Megane Coupe 1.5 DCI back in Europe for 4 years. It's also 105 hp version (non-dpf) probably the same engine and they're reliable. I wouldn't worry about the lead and silicon.

As far as i know, the recommended viscosity for 1.5 dci engines are ACEA C3 xw-40 with RN07XX approval. You can also try 0w40 or 5w40 next time.

I used Mobil 1 0w40 for more than 80000 kms and my OCI was 10000 kms. I'd recommend you to stick with 10k km OCI.

Hi dgunay.

Thanks for the tips.

What do you mean with "OCI"?

Thanks.

I thing you need to change the air filter much often, high silicon levels
