Hi can anyone tell me what oil I should use in my Peugeot 108 VTi 3 door hatchback 68 Active 1ltr 2017 plate. On some sites it says 5w30, 5w40, 10w30, 10w40. But the garage I bought it from which was Peugeot related put 0w30 synplus in it as it's on the work sheet service. I understand what the numbers relate to, but just want to make sure I use the most correct oil. Thanks for any advice you can offer me.
