armbFilled the Audi's tank yesterday, for the first time in a month or so, or rather didn't quite fill it because I hit Tesco's pay at pump £60 limit first, for the first time. I looked at octane booster additives in Discount Autopart, and they cost as much as the difference between a tank of LRP and a tank of standard unleaded. The BP garage on the A14 has 97 RON "Ultimate" unleaded, but it costs more than LRP. The car does actually seem to run better on standard unleaded + Redex lead replacement than it does on standard unleaded, even though the Redex says it isn't an octane booster and only replaces lead as a lubricant, and the Audi owner's manual says it's the octane rating that matters (if I'd read that at the time I couldn't get LRP, I probably wouldn't have bought the Redex).
Current plan for cars says use the Audi to go to the cottage after Easter (ideally without knocking the exhaust off again, possibly trying to fill some of the worse potholes on the track), then see just how much it needs to get through the MOT, and make a decision after that. We'll keep the Ka till then in case the Audi is either off the road for a while or dies, but it might be sold towards a replacement big car (one which will take five people and two dogs, and camping gear, and a dinghy or two - not necessarily all at the same time, and possibly with the aid of a trailer).
