Interestingly, it appears that though my car will be fine, my lawnmower will not. E10 is not recommended for lawnmowers because it is usually stored for a number of months during the winter. This means that I’ll have to fill up my little container with about £1.50 worth of unleaded, which will go down a storm at the kiosk.
Stick some V-Power in it you will be done in no time.
