Built like a Mercedes 3672

Things have changed a bit since 1968 plus 1 though. At least, they have over here Most manufacturers specify exactly the same oil up to 12000 miles as is the minimum US standard. That is API SL. It is a standard which is current and set by the American petroleum insbreastute. For goodness' sake, back in 1984 I was running UK built cars with 12,000 mile-1year oil change intervals on high sulphur fuel and far inferior oil to SL, I think it could have been API SF but I'm not sure. I had a VW Golf GTi 1.8 back in 1982 which had 10,000 mile intervals on the standard of the time. It was still running last I heard, which was a while ago, with around 180,000 miles on it. Yes, from 12000 miles up a better oil is usually specified. So what? Many people choose to use a better oil in any case. Long drain oils are increasingly common and are now almost the standard oils for diesel engines. Witness API CH4 which is equivilent to ACEA E3 or E5 or what used to be called 45000km super high performance oil. Oil is not rocket science for the consumer. One just uses the oil standard and viscosity as specified by the car manufacturer. It's that simple. Built like a Mercedes 3673 Huw That was very much NOT the case over here. Engines of the 70s and... Huw
