I'm almost certain that I am now going to use Millers xfe-pd 5w-40 505.01 (semi-synthetic) oil. I'd rather change my oil regularly and am not paying the prices of Castrols 506.01 'LongLife' oils. Millers is £21 for 5 ltrs and I would change every 6 months.
There has been a lot of discussion over the longlife oil. Has anyone any thoughts on using the semi-synthetic oil or is using anything other than Casttrol LongLife?
