Oil in purto vallarta

RYV: Have you looked at the label to see if it is an API approved oil? For gas engines it would be something like SJ,SL or SM. For Diesels it would be CI4 or CJ4. For some reason very few Mexican oils meet those approvals. Even the viscosities are wrong. I can find lots of straight gasoline oils or even 15/50. None are approved in Canada or the USA. Until recently most gasoline engines call for 5/30. I think some newer engines use 5/20. Both are rare in Mexico. For diesels in Mexico they like straight 40 or 50. Unless you have an engine from 1960 or maybe a 2 cycle Detroit those oils are not approved. You will see Diesel oils that are Series 3 Not approved. Again: The correct oils are available but not usually at supermarkets. Auto Zone has some of the correct oils. Brand name has no meaning.
