Fuel costs and cost of misfuelling on the up
The price of fuel is expected to go up according to media reports http://www.telegraph.co.uk/motoring/news/9824969/Petrol-prices-to-rise-by-4p-per-litre-in-coming-days.html which means that the price of misfuelling will also rise – fill up with wrong fuel (petrol), flush out the wrong fuel and fill up with diesel.
This, of course, assumes that the motorist has not started the engine and, worse still, driven, which could cause further damage leading to an even higher bill. The best strategy is to fit a misfuel prevention device https://www.dieselhead.co.uk/the-diesel-head-the-misfuel-prevention-device/ to prevent a misfuel – petrol in diesel vehicle – occuring in the first instance.
