how can I reduce fuel consumption in my volvo 1981 car ?

Question

the carborator is zeinth type.

Answer 1

keep it tuned up. check tire pressure... get new high MPG car.

Answer 2

I had an '85 Volvo for 6 years, but mine was fuel injected & automatic. If I didn't plant my foot in it too much it got as much as 25mpg.
Check your tire pressure...make sure they are all the same. You might also consider using the maximum tire pressure listed on the tire which will make the tire "narrower" which will reduce rolling resistance and save gas.
Eventually though dad and I had to change out the exhaust system. After that change the gas mileage dropped to 17mpg. It was caused by the increased back pressure from the catalytic converter. If you recently replaced it, you might consider replacing it with a "free flow" catalytic converter.

Answer 3

Is it a manual shift? cause if it is, always shift in the lowest power range possible, as all fuel consumption is RPM dependant.

If it is an automatic then simply ride the gas pedal as easily and slow-progressively as you can.

Stay Below 55 MPH or 90 Kph as that is the point at which the car starts pushing air forwards as opposed to simply having it split around the body.

Keep it well tuned, & index your spark plugs.

Answer 4

This may sound weird but studies have shown
that you get 10% savings by simply keeping your tires at the same psi.
I've found 9 out of 10 cars do not have their tires at equal pressure!

Answer 5

Either have it properly tuned. Or convert it too a chaper form of fuel such as cooking grease! It is possible but, expincive too have done ask a mechanic how to go about it!

Answer 6

stop driving it! lol

Answer 7
