I agree on using synthetic in every modern engine. My old Ferguson is supposed to have straight 40 weight non-detergent. That stuff is impossible to find in my neck of the woods anymore. I have been running Delo 10-40 in it recently. The oil pressure is fine as long as I don't work it hard, but drops more than I would like if it gets really warm. (fortunately it has been delegated to a light duty tractor) Where do you find straight 40 weight, Lou?
