Tips from Army Motors US and British Lube Equivalents
If this chart looks familiar, it’s because we printed almost the same thing three months ago. The only differences that matter are those in column 4, under Equivalent British Grade. But since column 4 is just about the whole reason for the chart—watch closely, please: British engine oils are now heavy duty like ours, full of additives and digestible in all our engines—including GM and Caterpillar diesels. British greases are now numbered like ours, and a little beyond. Be lube-wise! Amaze your friends! Bounce that January chart and pounce on this one.
