as soon as I had a change of oil, the question arose which oil I would take. on demand at the dealer he told me that volovo 5w30 prescribed. then I looked in the accessories trade what the good drop should cost. since this was too much for my taste, I immediately asked in the shop for an alternative. as an answer came, that also 10w40 would be possible, which is already better from the price. what are your experiences? or is there another choice. for tip I would be grateful…. thank you
