unleaded. they introduced it around 95/96. i member cos my dad had a few project classics and the entire classic car world had to have their engines modded with hardened valve seats or use additives. they replaced the lead based anti knock with benzene which is well worse for nature. in 95 a litre was 30p rising to 35p in 95 after budget. hit 50p in 98 and just kept rising. the biggie was about 2005 or so when it broke a pound and they had to change all the station signs to accommodate another digit.  difference is, back then people actually refused to fill on a few pence over. we saw during covid, it got to nearly 2 quid and dickheads were queuing round the block to fill up, only to then go on jewbook at complain that their mpv costs 150 quid to fill. if everyone just didn't fill up for week we could have a chance, but these days everyone is an atomised self interested cunt who would just jump the line for themselves and fuck the greater good. 25 billion a year queer starmer gets from fuel duty.
