My car done 140000kms and im wondering how often to do an oil change and what oil.
My mate swears that I must change it every 5000kms and use 10w40 (either 10w40 or 5w40) and NOT fully synthetic oil (for older Subarus with more kms). What do others think I should be putting in her?
Also, will supercheap oil filter be all good?
