I wouldn't put detergent multigrade into an engine I hadn't stripped and cleaned. But come to that, nor would I run an engine I hadn't stripped and cleaned...
FWIW, on the topic of bulk buying, most manufacturers advise engine oil should be used within about 2 years of purchase. That said, I'm still using up a case of Duckhams which has been unsuitably stored in the roof of my garage for at least a decade and I haven't blown anything up yet.
I've recently "switched" to Morris Golden Film 20W/50 which has one major selling point - their 5 litre containers are just the right width to tuck down in the spare wheel slot of the Ulster. Now that I have two containers, I shall probably re-fill them with whatever is cheaply available.
