Hello, I would like to know your opinion on this topic. It is about my vehicle, which is from 2002 and has the release API SJ or SL according to the user manual. The viscosity would be 5w30. My question is. The newer API standard is the SP. Since this is higher quality, it is said that I can use the oil with API SP? I asked the car manufacturer the same question. The answer was “As long as the engine oil meets the API SJ and SL there is no concern for use”: But when I read through the approvals, there is only SP and no others. Then I telephoned with a technician (large oil manufacturer). He said to me I can use the API SP without thinking about it. This is higher quality than the SJ or SL. Man can see this from the second letter. In this case it would be the P. He had to smile and meant the specification gives a worse oil than there is currently on the market. That comes from the 22 years ago the SJ SL were up-to-date. Thank you all.
