In an auris hybrid, after 5-30w, which they put me in service without asking me, the consumption started to increase to over 6.5 to 7 liters of gasoline. I thought I would leave it for about 5,000 to 6,000 and then change it. The difference with the 0-20w is huge in terms of consumption. The car is much calmer and the hybrid function works much better.
