Hi all

I am confused I need to change the oil in My Gransons Polo and I am being given different info as to which I should use. I will change it one a year and the mileage will be less than 10000. Can I use the more reasonably priced stuff or do I have to go fully synthetic. Also I have the same problem with my Corrolla, I have been putting 5/30 multivis semi synthetic (which was recommended to me) in it now to be told its the wrong oil. That to will do less than 10000 miles and gets changed annually. I have some older motors that I play with and they all get 15/40 and are quite happy.

Your help would be appreciated
