If you will send us about 20 gallons of the Oil you recommend for use on Rolls-Royce cars, we will endeavour to test this on one of our Experimental Cars. We cannot however, promise how long it will be before we can let you have the results of the test. We should anticipate it will be at least 6 months. Yours faithfully, | ||
