Petrol and diesel drivers can secure better fuel economy by using a simple spray on the inside of their vehicles, according to a top mechanic.
American motor expert Scotty Kilmer said using the vital tool on sensors under the bonnet could make a vehicle run smoother and even save fuel.
Mr Kilmer used the simple solution on the car’s mass air flow sensor which is connected to the fuel injection system.
According to the specialist, giving this a simple clean can also produce extra benefits such as better performance and more efficient engine idling.
Speaking on his YouTube channel, Scotty said: “I’m going to show you how you can make a car run better with a little bit of spray can.
“Now back in the day cars had carburettors and you spray claimed them with carburettor cleaner. Good luck finding a carburettor on a modern car they don’t have one. They use fuel injection systems with an electronic mass air flow sensor.
“And guess what, the sensors can get dirty and you can clean them with this spray. With the car turned off just unplug the sensor that comes off and unscrew it. Off come the screes and here’s the sensor.
“This side’s clean but this side is really dirty. It needs cleaning. Just spray it until it’s clean, It’s not rocket science.
“Now here comes the hard part, patience. You want to let it air dry for an hour, or if you’re in a hurry you can dry it with a hair dryer.
“Either way then you put it back in. That little cleaner can make them idle better, have more power and even get better gas mileage. So spray your troubles away.”
Carburettor cleaner can be purchased online or at DIY stores such as Screwfix for as little as £5.
The warning comes at an important time for motorists with petrol and diesel costs still very expensive.
Analysis from RAC Fuel Watch shows unleaded petrol prices stand at an average of 142.90p per litre, up by around 3p on costs recorded in January.
Meanwhile, diesel fees were also up to 151.30p, up from 148 pence at the start of the tear.
Experts at the motoring group warned prices were “likely to rise” shortly in an extra blow to road users.
