Other factors which decrease gas mileage are:
Worn or dirty spark plugs
Incorrect spark plug gap
Dirty air filter
Incorrect valve clearance
Dirty engine oil and clogged oil filter
Dragging brakes
Incorrect front end alignment
Low tire pressure
Some of the above mentioned items and others are checked at the standard Maintenance Service
intervals.
Deposit control gasoline
Volvo recommends the use of gasoline containing deposit control additives. These additives have shown
to be efficient in keeping injectors and intake valves clean. Consistent use of deposit control gasolines
will help ensure good driveability and fuel economy. If you are not sure whether the gasoline contains
deposit control additives, check with the service station operator.
Note:
Do not add additives yourself to the gasoline, unless you are recommended to do so by an authorized
Volvo dealer.
