December 14, 201114 yr I've been using a straight 40 oil from Morris for the engine, but it did take a long time to warm it up and get it moving round the engine given the very low temperatures at the weekend. Any advice on what I should change too given Jack Frost's appearance most mornings now. I have pre unit AMC lump...... Cheers

Just use a cheap 20/50 or even 10/40 if it's very cold and change it regularly. Most engine wear takes place when you start the engine from cold and when it's cold as you say it takes longer for the oil to get around and lubricate everything. Remember when these engines were made oil technology was almost non existant and modern oils are light years ahead of what they had then. Also far better to use a cheap oil and change it after every 3 or 4 trials than an expensive oil and only change it every 6 months IMHO of course.
