Thanks mate I used the best one from Halfords and litre was added and it’s just due a service that’s all which is booked in for next week so can’t wait 😜Read your manual, there are 2 specifications for oil for the TwinAir depending on the age of the car.
5w-40 for the earlier ones, 0w-30 for later models. Whatever you choose make sure it's compliant with
Relevant Fiat standards.
Mine uses no oil whatsoever, and that gets driven pretty hard.
