We have used Nanolub ( RC-X) for several years now, mixing it with synthetic, semi- synthetic as well as purely mineral oil, often in very dry and dusty (= desert) environments. Our experiences in mixing the stuff with all types of engine oils are excellent. It does not really matter what you have in stock for us, so long as it is Nanolub and comes in 150 ml. or ( preferably) 250 ml.
