This was, as I recall, discussed at length(ad nauseam) on the old site, but I can't seem to get back to that thread. I know that many are running straight 30w. The question is, detergent or non detergent? The engine was built by Pigsty and it has been run on Halfords Classic 20/50 until now. The car will be coming to the US, and finding a non detergent oil will be an issue. It is splash fed with a spin on filter mod. The Chevron Delo 400 has phosphorus and zinc in low percentages. I had thought about running that in the gearbox also, but understand that phosphorus and detergents are bad in the gearbox. The phosphorus, I understand, will wear any bronze bushings.
