Good morning,
FCA calls for an oil meeting Fiat 9.55535-GS1 or DS1 depending on whether you have a diesel or gasoline engine. These oils are few and far between, in the U.S. the only readily available oil is PP Euro LX, at least in 0w30 flavor. I noticed that Ravenol FES 0w30 states that it is suitable for use in this application but does not have a formal approval. I questioned Ravenol and received the following response. Take it for what you will, but it would appear that FCA may be doing a little 'pay to play' regarding their formal approval similar to GM and Dexos.

Question; "I noticed that FES 0w-30 does not have 9.55535-GS1 formal approval, however, you state that it's appropriate for use in such an application. I'm curious, is there a specific reason why this oil doesn't have a formal approval? Also, what testing was conducted to ensure that this oil will adequately protect engines that call for this specification?"

Answer; "Ravenol FES 0w-30 has been tested by Fiat in order to prove the suitability. We do not know much about how they conduct those tests. After a positive result we make it public. However, to take an official approval or not is another commercial decision which involves larger investment. We appreciate your interests." - Jade Hsu / Ravenol
