CaRFG AFFECT ON FUEL ECONOMY
A very small reduction in MPG (less than one-half MPG) is possible if the customer uses gasoline without oxygen­
ates. This is attributed to the lower energy content of oxygenates, which have been included in all Southern Cali­
fornia gasoline since January 1995 and some gasoline since the 1970s.
NOTE: Driving habits, vehicle maintenance and weather conditions all affect fuel economy. Fuel economy may
vary more than 1 MPG from one fill up to the next using the same gasoline.
NO SPECIAL ADDITIVES ARE NECESSARY WHEN USING CaRFG.
It is not necessary to add anything to the vehicle's fuel tank after CaRFG is purchased from the service station.
California regulations require deposit control additives in CaRFG to avoid port fuel injector and valve deposits.
OLDER VEHICLE'S PERFORMANCE USING CaRFG
Older vehicles are expected to operate satisfactorily on CaRFG because these vehicles have been operating on
gasoline similar to CaRFG for a number of years.
However, considerable testing indicates that older, high mileage vehicles are more susceptible to fuel system
problems due to age and normal wear and tear regardless of whether they are operated on conventional or
CaRFG gasoline.
NOTE: Owners of older vehicles are encouraged to have their vehicle's fuel systems inspected periodically and to
follow their vehicle manufacturers recommendations regarding vehicle maintenance.
ODOR EMMITTED FROM CaRFG
CaRFG is not expected to smell different from gasoline most vehicles currently use. If unusual odor is noticed, it is
probably be from oxygenates. Most service stations use vapor recovery systems to minimize gasoline vapor
release to the atmosphere during refueling.
