The question of what oil to use in a Vintage Bentley frequently comes up and there are multiple correct answers. The choice of one oil may not be the best choice for every Bentley – for example, a freshly restored engine as opposed to a well worn one. There is also climate and amount of use the car receives that needs to be considered. An oil for modern engines is not necessarily suitable for vintage engines since they are made of different materials and are designed differently. Add to this the variety of fuel blends available. I prefer Mobil I synthetic but it is expensive, especially considering the large oil capacity of the engine.

Hemmings Motor News, a 59-year-old auto publication that is the "The Bible" of the old car hobby in the USA, and one that I have been a 50-year subscriber and advertiser to, has just introduced a synthetic oil formulated for vintage cars. I have not used it, nor have I read any reviews on this new product so I cannot recommend it. But I think it is worth looking into and I look forward to hearing reports of its ability to out-perform other oils. http://www.hemmings.com/classicoil/
