[QUOTE="Tnecniv Edipar, post: 165344, member: 418"] Vincent engines don't get the oil upto operating temp very quickly, especially in moderate climates, and the oil tends to run relatively cool, like it's doubtful you would see much more than 80-90 deg c, even in a warm climate. So, a multigrade is advisable, so that cold start circulation is achieved as soon as possible, as most engine wear occurs at cold start. Also, as oil change intervals are quite frequent, synthetics aren't any advantage, especially considering the low specific output and low revving Vincent engine. I've had very good experience with Penrite and Motul. My choice would be Motul 3000 4T, 20w50, high spec mineral oil at API SL, much better than the so called classic oils which tend to be API SG, which is an 80's rating, and at a good price. [/QUOTE]
