another oil question

redrange said:

i always thought 10/w40 semi, castrol gtx magnetec for example is the oil of choise! i now reading that the 4.6 isnt keen on semi synthetic, and maybe 10w/50is an option!! maybe not as its getting colder now! choises choises choises!
its a recon engine 8000 miles ago, has a slight follower tap when hot when returning to idle after reved, its never got worse and with the agro i had with the garage that done it its never going back there hence i suffered it.
what oil? wish i never read the other thread now, DOH!!!!!

10/40 will be fine for your engine.

Use castrol GTX.

I had this problem in my earlier thread, I used 10/40 semi but ever since using it I have also developed a tappety noise, will be replacing over the weekend with mineral and will let you know how i get on.
