Tesco's 100 ron?
 

Is this as good as Optimax to put in a tuned Scoob:wonder: :thumb:

where is this 100ron fuel at mate? i use tesco 99 in my jdm wrx. better fuel economy than using optimax and runs smoother too.

:cry: whoppps did i say 100 :cry: I meant 99, so Tesco's 99 is good stuff then?

oh yeah for me its the best, maybe as ive an 11 year old car with a 13 year old engine. i dunno as i believe the earlier wrx's 93-95/96 maybe? - they were mapped for lesser octance fuels such as 97/99 ron, rather than the more modern classics mapped for 100ron after that became available in japan.

i honestly prefer tesco 99 over optimax or anything else, its just what my baby prefers and runs best on.:)
