Why not consider lift sharing? I’ve been lift sharing for about 6 months now and my wallet has definitely noticed the difference!
I used THIS website to find other people making similar journeys and ended up sharing with up to four other people which cut my weekly commute from around 300 miles to between 60 and 120 miles. Not only has my diesel bill dropped dramatically, but with much less milage on the clock, my oil changes have become much more infrequent too.
You meet new people and know that you are helping to cut carbon emissions and saving yourself money at the same time. Everyone’s a winner!
