Me again. I had the Polo serviced yesterday and they put 10-40 semi synthetic oil in. I have only ever used 5w-40 full synthetic oil before yesterday because that's what they previously used.
Is it OK to mix the synthetic oil with the semi synthetic? And can I use a 505.00 spec oil in an engine that uses 502.00 spec?
Thanks everyone.
