Hey guys I’ve just bought a Leon fr tdi mk2 170 which has been mapped to bout 240, has a hybrid turbo and dpf delete. Is there any recommendations on what oil to use as it is On bout 100k. I was thinking of changing to 5w40 as it’s mapped and high mileage as gonna do an oil change but recommends 507 spec oil which is 5w30? Would it best to stick to 5w30 grade oil or change to 5w40 and would it so any harm? Any replies will be much appreciated cheers
