Renault Bus PR 100-2


Hi all,
Can anyone tell me if wanting better fuel economy, is it better to change the original Renault 260hp diesel (2.4kms p/ltr Perth to Geraldton towing a 3.5t Trailer) to a 300hp CAT (100kms per 10ltrs so I'm told) or just change the governed diff from 85ks to 100ks??

There is no way a 300hp Cat is going to get that sort of fuel economy.
It sounds like your bus is a city bus, so best course of action would be to change the gearing.
