Now we are going into the colder weather the EV range on our Outlander PHEV will decrease, will have to starting using more E10 petrol. Being a PHEV which we regularly charge up home making it very difficult to measure the effect of E10 fuel. When towing the majority of time, we are running on petrol making it much easier to measure the effect.
I lasted fuelled up the middle of September returning from a holiday towing our caravan, I will probably fuel up in December not sure to whether I will refuel with E10 or super unleaded E5.
Unfortunately I have suffered a brain injury and occasionally I get confused and often say the wrong thing.
