I assume you are talking about oil. It depends on the year for pre-2010 use a 5W-30 product that meets both ACEA A5/B5 and ILSAC GF4. For 2010 use a 0W-20 product that meets both ACEA A5/B5 and ILSAC GF5. The bottle will show if they meet these standards. Anything other than the standards that are met is just sales puffery, including terms like synthetic.
The G and S grades are the old standards.
