I was looking into upgrading from CL9 to a CU2 today... I was research for the possibility for some USDM Acura front grill/bumpers to be put in (cause I just cant get over the looks of the CU2... what the hell were they thinking when they deisgned that thing...)

Anyway, I found something interesting for the USDM vs AUDM K24Z engine... Everything else seems identical... except...

1. Power: USDM K24Z produces 147kw instead of 148kw on the AUDM K24Z
2. Fuel: USDM K24Z recommands 91RON (can even use mid-grade 89 RON), while AUDM is 95RON min.
3. Fuel consumption: USDM 10.69/7.59Liter per 100km (City/Highway) | AUDM 12.3/6.9 Litre per 100km (Urban/Extra Urban) *

*There is differences between EPA and ADR on fuel consumption, EPA (USA) tend to calculate less for "City" compared to ADR "Urban" and EPA (USA) tend to calculate higher consumption for Highway compared to ADR "Extra-Urban", the difference is +/- 10% it appears over all.

So.... I can jsut imagine how much money I can save with the 91 Ron... LOL.
