Barry Posted October 3, 2017 Report Share Posted October 3, 2017 Fuel boosters are a scam to make money for the fuel stations. Start with the basics. Has your driving style changed? Is your air filter clean? Are your spark plugs in good condition? Link to comment Share on other sites More sharing options...

shadow79 Posted October 3, 2017 Report Share Posted October 3, 2017 (edited) yes general tune up should be the answer like throttle clean plugs change and air filter change if there is a fuel filter then change that as well if you really wanna go that way then try bng it has effect to some extent others are snake oils...do you feel any type of unusual vibration at idle or only the milage drop ?

If you were always in UAE, then not required to be honest. 1 Link to comment Share on other sites More sharing options...
Barry Posted October 15, 2017 Report Share Posted October 15, 2017 While you might not need to change the petrol filter often due to blockages, it's best to change it every 50-60k due to degradation which will decrease fuel flow. On older vehicles with metal tanks, it should be changed more often. The tanks corrode internally and small flakes of rust can cause a lot of damage if they were to get to the injectors or carburetor. The gauze in the fuel pump will catch most of the larger stuff but some small pieces can get through. Diesels are a different story and the fuel filter is generally a service item to be changed along with the oil filter. Especially in modern common rail systems with high pressure pumps, the smallest particle can wreck a pump causing a huge repair bill. 1 Link to comment Share on other sites More sharing options...
