I have just bought a couple of 5ltr cans (plastic) of Shell Diesel C 15W 40 engine oil API CD. I bought it in France from a Carrefour. I have tried to find it on the Shell web site, can I hell!

Anyone got any knowledge of this oil? I dont mind stocking up on my French trips, but it would still be nice to find a source in the UK.

I buy my oil at Carrefour. Much better prices than the UK but not as good as when the £ was worth more euros!
I don't know about the Shell, I use Total 5000.

Where you bought it is not really relevant.

It's a SAE 15W 40 oil conforming to the now obsolete American Petrolem Institute CD specification for diesel engine oil. Provided your engine can use such an oil it will be Ok but it can be argued that you should use the latest appropriate spec oil.

See HERe for a list of API specifications.

There are also ACEA specifications, the European equivalent. I am told a better system than the API one.

All I can tell you is that API CD is a mineral oil and is now obsolete and had been since 1996.
API is the American certification code for engine lubricating oils and others may be.

The "C" is for Compression i.e. Diesel where the "D" is the blend type of it's time. If it's starts with "S" this is saying it's for Spark i.e. Gasoline. I believe that the oil you have obtained is saying that it is at least to the spec of CD or better, of it's production date I can not help you with that.

This was the specified oil for my engine (135hp Perkins Sabre) according to it's service book and it has been on 15/40 semi synthetic for sometime now which is more practical in terms of longer life and if I do get caught out I can top up with either synthetic or mineral.

Hope this goes on to help you in some way because the more you look into it the more confusing it can become. If in doubt check with your engine dealer or an oil supplier.

Good luck.

It is Shell Rimula C, which was withdrawn in UK until early last year but for some reason is still available throughout Europe. I always use it. It is the perfect oil for most yacht auxiliary engines (Bukh, Yanmar, Volvo, others) all of which still specify lubricant to API CD.

You can see a detailed response to your question on my website. A brief summary is that automotive diesel engines have developed enormously in the past 20-30 years in terms of power, temperature, oil stress, service intervals, etc. The yacht engines mentioned above have not developed in the slightest in that time, and neither has their duty. They run cold, for relatively short periods, at steady throttle settings, and rarely flat out.

There is good evidence that using oils with later specifications, especially those intended for high power output turbocharged engines, will damage your engine in the medium term.

For those who do not have access to API CD lubricants, Shell make a product intended for marine leisure use, Nautilus Premium Its grade is CF, which has a higher base number than CD but is probably the next best alternative.

The replacement grade for CD is CF, and even that is becoming difficult to get hold of in the UK. I bought in error a semi synthetic 15W-40 rated CF the otherday, and don't know whether or not to use it! I have drawn total blanks from all the outlets except for a Castrol GTX Mineral CF of 10W - 40 grade. I presume this means it maintain its runnyness (new word) at cold temps, in which case perhaps I should go for this.

Come in Vyv Cox.... I am sure you will have some advice!!!!

Reading the info on Vyv`s website, Morriss oils in UK do a diesel 15/40 CF-4 that is available and stocked by many motor factors at a considerable discount below Shell, Castrol prices

Many of you have missed the point of my post. I know as much as I need to know about which grade oil to use, and whilst I can I will always buy API CD, as advised by the very knowledgeable Mr Cox. Vyv, your photo is exactly what I have! As for suggestions of Shell being expensive, I paid around £12 for the 5 litres.

The reason for my post is my puzzlement that Shell dont list it at all on their website, curious.

True. Thought you were saying that you found this cheap oil, couldn't find it on the Shell website, can anbody tell you what it is.

What you really were asking is why dont Shell list it on their website.

God knows (hopefully). Suggest you ask Shell. They should know as well!

It seems that Shell may have confused both me and my adviser in the company by another name change. By following through the products portal for 15W/40 automotive oils it is possible to arrive at X100 with the specification API SG/CD. This suggests that an API CD oil is still marketed in UK (and France) under the name X100 but not under the names Rimula C or Diesel C! So it should be possible to buy the correct stuff from one of the Shell suppliers, e.g. EMO.

I have updated my website info accordingly.

Gave up trying to find it on the EMO site. The Morris site is much easier follow this link

Get your point now, may be Shell doesn't want to list a product that was first produced circa 55 years ago along with it's old technology of a high sulphur oil. Things have moved on a bit I would say. Surely CD is just a grade recommended by engine manufacturers to be a minimum grade and the superseded type/grade would be a better alternative.


I wait standing to be corrected. Are you out there Vyv Cox............

My Shell colleague tells me that Shell no longer manufacture API-CD grade oil in Europe although stocks may still be available through some outlets. Shame really since good old basic Rimula was good stuff and ideal in old slow running marine diesels.

No, you are not correct. Already answered. Please read the thread and my site.

OK as I said in my first post on this topic "the more you look into it the more confusing it can become" and yes I have read your web site and it has some contradictions as far as I read it.
The reason I looked into engine oil types was because my engine is and has been on semi synthetic since it was put into commission in 1997 but the service manual says use no less than API CD which as you know is a mineral based oil. Ha, guess what I found it was obsolete, so where do I go from here.

Should I leave it on semi or change to a mineral oil? Not CD because I can't find it. The boats was in Italy and at the time I was in the UK. I tried Italy, Croatia and Greece with no avail. The engine runs as sweet as a nut, it's done 3.2k hrs and starts first push with no pre heat no matter what the ambient temperature is, and in all this time has never had a spanner on the engine other than for
service requirements.

I had great difficulty obtaining any information on mineral/semi/fully types of oils for my engine from Perkins, oil manufacturers and suppliers, marine engineers and engine rebuilders.
I have read numerous articles on oil types on numerous web sites and still did not come up with answers I felt happy with mainly because of contradictions between them all.
So ok, CD oil was first designed in 1955 and was made obsolete in 1996,

So why was it made obsolete if it's specified by major engine manufacturers? What is the difference say between CD an CF or any other C type oils for that matter?

As your web page states "Engine lubricants may be considered as having two main components: the base oil and the additive package" what does the additive package consist of?
It also states "Yacht engine operation, however, has not changed in the slightest. " may be not, but the engine has? As in improvements of materials, machining in it's production, different injection, indirect to direct and even to HDI in some cases, also cleaner fuels now red is being phased out, but we have to use road fuel in the rest of the EC.

My engine (Perkins Sabre) is used in road and plant applications. Fair enough road is different to plant but surely plant application is as near to yacht operation as you can get, i.e. gen sets, excavators and so on, as in running at constant speeds and fairly static temperatures. On my questions to the operators of these uses all sorts of types of engine oils where used.

I don't want to enter a battle over oils more that I and may be others just need to understand more on oils without getting bogged down in waffle.What should be used and what not, what's available and what's not?

The answer to my dilemma has been to change the oil and filters annually. After all a couple of gallons of oil and filters is a cheap spanner in my view.

But this link leads to an oil with a spec of API CG-4 / CF-4 / SJ / SL which I guess is well in excess of CD.

Interestingly, I note that Morris's do a couple of CC oils recommended for canal boat engines, but I haven't been able to find one that is CD only. I'm assuming that anything specced as CF4/CF/CD in fact exceeds CD so is not ideal. Any views on this.

Vyv's research shows that CF-4 is acceptable. Our neighbour down the road is head of Shell Lubricants, known as King Oil, so I will get my son to ask him about all this!!!
