I'm currently using 5w40 fully synthetic oil, changed it as soon as I bought the car - about 6k km ago. Engine has 238k, but I'm not sure if it's true, since in my country most people reduce the mileage before selling cars (sucks, I know). The sound comes from engine bay, but it's coming from the middle/right, so I will check if maybe my manifold is leaking, read about the DISA valve and will change the oil. Could you recommend me which oil should I use? Considering that we have pretty cold winters (up to -30C sometimes and hot summers +30C) |
