I think you misunderstood me. Here in Europe, the ACEA has priority over the API. This is due to the fact that the requirements for an ACEA specification are higher than the requirements for an API. We do not have a speed limit and sometimes drive longer oil intervals, so Honda prescribes an oil according to ACEA in Europe.
We had another discussion today about turbo direct injection engines. The majority of people thought it would be safer to use an oil according to API SP to avoid the danger of LSPI. Is this really such a problem because of the oil? So far, I thought that it is increasingly the fuel used, driving style and above all the design of the engine. How do you see that?
