Hi
beaver i have a dolphin motorhome on hilux v6 chassis. im still improving mpg. got a lot of tips from youtech?. Have flushed cooling system fitted new thermostat serviced engine altered timing to 15 dregees btdc and changed auto box oil to dexron 6. Seen mpg go from 13mpg to 16mpg. still waiting to run a full tank without coolent leak etc etc. next on list is to alter vane in airbox and fill diff with a synetic 75-90 oil. then in spring start on aero mods as sub zero temperatures prevent fibreglass from curing.
