Well I have managed to find some Mineral oil at my local motorfactors, it's a brand I have not heard of before but I was using Morrisons own brand last year so I am not too worried. If anybody has heard of these and could give me either a thumbs up or thumbs down I would be grateful, The company is MPM International and the oil I purchased is
Motor Oil 15W-40 Super High Performance Diesel It was the only Mineral oil I could find available locally off the shelf (Eurocarparts do not offer free delivery to the lake district!!).
Does anybosy know what thread size the valve type sump plug is, I may have to helicoil it this year!!!!
