As we all know the 1.6vti engine uses oil by design. My 2009 1.6 sport was serviced using Mobil esp 5/30 which at £18 litre is painful! Has anyone used comma protech 5/30 in their 308? This retails at £5.99 litre and £21 for 5 litres and is designed for Peugeot engines.? I have always used comma oil in my previous cars.
