Without getting too carried away most modern oils cover both. The S is for petrol the second letter is the quality. The further down the alphabet the better the oil. The C is for diesel and again the more you move along the alphabet the higher the quality. Now there's a hell of a lot more going on with oil than that. But for your question yes is the general answer unless it's some highly spechilised oil out of some unusual engine. Look for the S and buy a good quality oil from a reliable source. I'd say sg or higher. Don't ask about Grade unless you want 50?answers.
