Engine: Petrol, This was on 95RON, Mr rolling road man told me I should run it on V Power though.. Size: 1272cc, Chip (with 8k limiter..) Pipercross, 4 Branch manifold, performance exhaust, P&P Throttle body, skimmed head (higher compression ratio..) Model: 1991 Polo GT Driving Conditions: Good run to watford (120miles ish) to work and back, half country, half A and Dual carriageway, so averaging a 'good' 60mph mostly! Combined MPG: 42ish, Full tank, 189miles, required 20 liters to full up. Rated MPG (manufacture) : No-idea, 30-45ish Comments: Pretty pleased, thats with occasional limiter bashing, a close ratio box, with little concession to fuel economy when it comes to driving style, could increase it to 45mpg I reckon.
