Yet another thing has gone wrong with my car! There is a fault with the anti pollution sensors (3 of them apparently). It's very intermittent and given that I've spent over a grand on it so far I'm not rushing to fix it!
My question is for all you petrol heads and mechanics..... Would the type of petrol I put in affect wether the sensors work or not?
I've noticed of I fill up at BP (not this week obviously  ) or if I use the premium unleaded the fault disappears.
Is this a coincidence or am I onto something?! |

If the problem goes away with premuim unleaded then try using an octane booster additive in your next tank fill up. Will take the RON level from 98 to 101.
Or if you can get hold of some aviation fuel. It’s 105 RON. |

I'll see what they've got spare at the local gliding club  (for. The tow plane of course, I know gliders don't need fuel  ).
What am I looking for when buying an octane booster? Make etc? How often do I put it in? |

I haven't got a clue but I have now found out who to ask should I ever need a fault diagnosing.  |

I asked the local village mechanic |

To answer you question as to Whether the fuel will affect your sensors then the answer is yes. Low octane fuels burn with more sooty deposits than higher octane fuels. Race cars use high octance fuels developed in labs for extra bang.
The sooty deps cling to the sensors and block them up. Depending on your driving style. I drive hard so my exhaust gases are hotter than someone who drives conservatively
It could be a factor also that your car is due a service. If not already had one. Oil change etc. |

So I should rag my car down the dual carriage way as well then |

If you do mostly short journeys then It’s certainly worth getting it warmed up with a decent trip down the motorway. If you’ve got fuel.
I don’t know the age, miles, or model but sometimes sensors just wear out. I had a lambda sensor go in the manifold of one of mine and it was only about £50 to get it swapped. |
