DDK - Die Deutschen Klassiker

Has anybody ever heard about or used these oils in their 356/912? I saw there trade stand at the classic car show and popped over for a chat with the guy on the stand. He reckoned that the APG 40 (multigrade 25w/70) was the best stuff to use in a 912 and would offer superior protection than other oils on the market. He claims that it is thicker than other 'classic' oils and offers superior protection at high temperatures. He also reckoned that most other oils would dry out internal seals and make them very brittle (which would eventually lead to leaks) whereas there's would not. He also added that it was a lot purer than other available oils as most recycle old oils and blend with new. The guy told me that he drives a 356 himself and that he uses this in his. It seemed quite expensive at about £15 for a 2 litre bottle just wondering whether its worth the extra dollar or not?

Personally I don't know the product but I would use the extra cash to change the oil more frequently rather than use something that purported to have magical qualities. I would ask him for some data next time... Oilman on PCGB would be the best person to ask, there is nothing he doesn't know about oil. Just my 2c.

I'm no oil expert, but I find those sales people at shows certainly know how to sell something that is pretty normal, run of the mill. I'm sure somebody with more knowledge will respond but a 25/70 seems rather thick to me. Personally I'd stick with a good quality 20/50, from manufacturers such Fuch/Silkolene, Morris, Miller.

Hmm interesting, might have a word with oilman like you say. Would be interesting to actually see some figures or evidence of improved protection/cooling like you say. I didn't buy any from the show as I wasn't sure whether to believe the hype or not. I agree with what you say though Nige a lot of the time they can be full of hot air.

too thick

that was what I first noticed when I saw that.. but like Nige says sales men i wouldn't trust them..ops i'm one

All seals will dry up as such mainly though age and also cheaper raw materials being used. I'm not having a go but I have had some seals from RB and they are no as good as NOS old ones I have. The new ones leaked with in a few thousand miles ( crank seals ) the rubber has too hard a connent to it and it comes brittle very quickly, a s ure sing they are made cheap. Sorry my Dad could bore you to death on Silicone seals

I'm with Gavin - Frequent changes using any of the standard good quality mineral oils, would be very hard to beat.

Any good product would stand up to a dose of healthy scepticism. The rest is marketing bravado
