Saving pence, spending pounds

My wife took her 2002 RAV-4 for a service, which was uneventful. However, a few days later the engine management light came on, so back it went. The service dept at the Toyota garage said (and I paraphrase as I wasn't there) that it was one of the 'oxygen sensors', which I believe to be something in the exhaust system that tells the engine computer how much fuel to squirt in. The mechanic said it often comes on if supermarket fuel is used all the time, which in this case is true as my wife is averse to spending money (a trait I admire). Does this mean that supermarket fuel is actually deleterious to our car and if so should we claim against them for the repair?

Yes. If a car is used for short runs than it needs the best fuel with the highest octane and the best detergent. I use Shell V-Power petrol even in my FIAT 500. No grounds to sue the supermarket. Your wife bought cheap fuel and that’s what she got. Some days you can be lucky with standard 95 Ron supermarket petrol. Some days not. Depends where is has come from on that particular day. And if in doubt you can always use Tesco part bio 99 Ron Super.
