i have a 2002 volvo s40 1.9 litre engine
from canada, so it costs me approx 55 dollars to fill up and i get approx 500 kilmetres on a fillup, here where i live is 1.28 a litre
so really dont know what is my miles per gallon, bad at math
i want to get better milage,,,

few ?'s do you's belive in those additives you can add to the gas to get better fule milage or fuel injectin cleaner that you just add to the gas tank, do those work

for mthe volvo, what would you do for a tuneup,,spark plus, spark plug wires, rotor, air filter,,just changed my oil to synthetic,
i have 107,000 kilmetres

input really appreciated?

 

I would run a bottle of the injector cleaner through the tank and do a tune up.
Plugs,filters, maybe even wires and coils.

 

thanks tech

reading the fuel injeCTION CLEANER bottle, cleans entire fuel system by removing harmful engine deposits from fuel injectors, intake valves and ports, intake manifold and combustion chambers, improves performance and fuel efficiency, reduces run on and elmates rough idling, safe for milti port injection systems and catalyic coverters,,,
it says to add 100 ml every other fill up

tech,,,will this some how trigger an engine light to come on....if using this fluid
should be safe to use, correct

thanks

 

Yes it is safe to use.
