Well then, folks want it so folks get it. Without the dopey oils spam
Rather than meandering through the BS of what oil does and how wonderful it is. Simply post up what you use/how much/where from (unless its opie )/the use you give it (inc engine) and how often you change it.
eg
Engine oil
Millers 10w60 CFS (fully synth), £30/5L, BJ Ashpole in Bishops Stortford, Regular road use in a Z22SE 20K/year and the odd TD, every 9-12months or so
Gearbox fuid
Castrol SMX-S, £10/litre from halfords. Same regular road use. Changed once
Silkolene Syn-5 CRAP dont use it!
Brake fluid
ATE SuperBlue, £20/litre from k300motorsport, reg road and some track, changed 12-18months. Fantastic fluid but stains the pipes.
Mintex bog std dot 5.1, £10 for 3 litres from BJ Ashpole in bishops stortford, changed once thus far. Great fluid, dirt cheap so if it boils its not a bank breaker etc
