Anyway, cosmetic mods aside here are the current ecomods. Economy is rated at 31MPG EPA (29/34) and I got 32.5MPG / 7.2L/100km with a 96 mile / 155km trip involving a bit of city driving, a bit of country backroad, a mountain pass I bounced off redline through, and then a 75mph cruise-controlled freeway stint. I feel 40mpg wouldn't be too hard to achieve and wouldn't be surprised with 45 with a few more mods and a bit of finesse.

Mods as of 24/2/25:
  • Factory alloy wheels with 185 width tyres
  • Tyres inflated to 45psi max load rating
  • Spare tyre replaced with plug kit & hand pump
  • Interior cleaned, no extra items/addons
  • Engine oil flushed & changed for 5W-30 synthetic
  • Nulon E20 teflon treatment added to engine oil
  • Fresh air & oil filters

Mods yet to come:
  • Gearbox lube about to be changed for full synthetic 75W-85
  • Nulon gearbox teflon treatment to be added
  • Passenger mirror delete
  • Power steering delete
  • Lowered suspension
  • Front lip / rear kamm

I'll see how far I get and what sort of economy I can push out of this little thing. Bear with me!
