Just a heads up for everyone, tescos fuel is causing problems again like a few years ago, not sure if it's affecting 99 Ron. Apparently affecting most Wales, the northwest of England and the northeast!
What kind of problems? Just keep your receipts just in case -) Shell has gone down the pan recently as well, I have more power running tesco 99 rather than Shell fuel.
High silicone levels, it happened a few years ago and ruined a shit load of people's O2 sensors. Luckily at the time my car was carbed so didn't have any problems. Like I say just be careful even if you keep your receipt the annoyance of having to replace an O2 sensor wouldn't out way any financial reimbursement.
Thanks for the heads up even thou i do not use this fuel, but alot of friends swear by it. Where would one look for updates to find information like this on fuels available or do you perform a test on the fuel or something?...
I heard about it through another forum. It seems some people have had O2 sensor failures and it's common to tescos fuel, not entirely sure if tescos have taken responsibility just yet. I believe silicone is used in fuel to reduce its evaporation rate while under high pressure, but if too much is used I think it burns out the O2 sensor.
