I think you are correct, they don't do CD now. Talking to them about maybe marketing some is on my to-do list.
API CD Oil - is this it?

How close is a CC?

Yes, that's about it. The TBN of CC is 3 and of the CD it is 4. Probably very little other difference. A current thread about Bukh engines mentions the DV10 used in lifeboats. The oil for that was CA with a TBN of 1. Not sure if that is still used, or even made, but it does demonstrate that these low TBN oils are much of a muchness.

So what is wrong with the oil that was in the original link?

| CJ-4 | Current | Introduced in 2006. For high-speed, four-stroke engines designed to meet 2007 model year on-highway exhaust emission standards. CJ-4 oils are compounded for use in all applications with diesel fuels ranging in sulfur content up to 500 ppm (0.05% by weight). However, use of these oils with greater than 15 ppm (0.0015% by weight) sulfur fuel may impact exhaust after-treatment system durability and/or oil drain interval. CJ-4 oils are effective at sustaining emission control system durability where particulate filters and other advanced after-treatment systems are used. Optimum protection is provided for control of catalyst poisoning, particulate filter blocking, engine wear, piston deposits, low- and high-temperature stability, soot handling properties, oxidative thickening, foaming, and viscosity loss due to shear. API CJ-4 oils exceed the performance criteria of API CI-4 with CI-4 PLUS, CI-4, CH-4, CG-4 and CF-4 and can effectively lubricate engines calling for those API Service Categories. When using CJ-4 oil with higher than 15 ppm sulfur fuel, consult the engine manufacturer for service interval. |

Nothing as far as I know.

I think it's worth bearing in mind that the 2000-series VP engines were introduced in 1983, and so the manual would probably have been written in 1982. At that time, CD was the best quality oil available. Volvo Penta are, of course, keen to sell their own-brand oil, which at that time was CD rated.
When the next generation of VP engines, the 2010A/2020A/2030A/2040A, was introduced in 1993, the oil specified in the manual was again CD, probably because that was still the rating of the VP own-brand oil. Fast forward to the introduction of the "D" versions of these engines in 2000, and the manual then was specifying CH-4 oil. Same basic engine, same bearings, same seals, but a higher oil spec, because oil grades had progressed and better engine protection was available.
So, I wouldn't worry too much about trying to buy old-spec CD oil just because that's what it says in the manual. Times change, oil gets better, why not have the benefit of better engine protection from a better grade of oil?

We have had this discussion so many times that I really cannot be bothered to continue it. Just answer the question I asked last time, or maybe the time before that. If API CI-4 is a perfect substitute for CD, CE, CF-4, CG-4, and CH-4 oils, why do the oil companies still make them? They would be delighted to only make one grade that suited every engine. It happens with most commodities, e.g once NEW DAZ has been introduced do you suppose they still make OLD DAZ?

Vyv Cox's website explains why the later higher spec oils may not be ideal for older yacht engines
pvb

Yes, I understand that Vyv has certain views on the subject. However, the point I made about VP raising the recommended oil spec for their 2010/20/30/40 engines during the production run is valid. If the more modern oil grades are as bad for yacht engines as Vyv thinks, why did VP upgrade their recommendation?

To be fair, though, CD is now almost unobtainable, which suggest that most oil companies do think that a perfect substitute is available. That's not to doubt a word on your website, of course, though I confess I still haven't a clue whether anything other than CD will ideally suit my 1GM10.

The only article you've referred to is Vyv Cox's website, and he's known to hold views which aren't shared by others.
So you're suggesting that Volvo Penta would recommend an oil which would damage their engines? I don't think so.

Perhaps 'others' know less than he does. Vyv may have learned a little during a career as a metallurgist in the oil industry with a "primary responsibility...for the diagnosis of engineering failures". He's also now in a position to say what may have been more difficult then.

I wasn't in any way denigrating his experience, simply pointing out that there are various opinions on the oil issue. As I pointed out, the fact that Volvo Penta upgraded their recommended oil specification for the 2010/20/30/40 series engines between 1993 and 2000 would seem to indicate that, in the manufacturer's opinion, better quality oils are suitable. For the current D1/D2 engine range, Volvo Penta recommend even higher spec oils, up to CI-4, yet these are similar technology engines as the older ranges, and are used in the same way by many boatowners (short runs, low revs, light loads, low temperatures).

To be fair Volvo have a reputation for ramping things up, esp prices.
I don't think my engine manufacturer cares which oil is used as long as it is 20:40. For reasons of economy I can think of no reason to go for anything but the most basic, Mineral stuff.
