The position is that it takes a tremendous amount of time before we can definitely recommend a certain brand of oil. It is quite impossible for us to carry out tests on all the different oils which are available. We should not anticipate there would be any trouble arise by using Shell oil on either a Phantom or a 20 HP. RR. car. Hs.{Lord Ernest Hives - Chair} | ||
