According to specialists at CarShop, picking the correct engine oil can make a significant difference in how efficiently your vehicle runs.
The motoring experts said: “Making sure the right specification of engine oil is used is important to improve a car’s overall efficiency, including fuel efficiency.
“The vehicle handbook will be able to indicate the correct type of motor oil to be used within the engine.
“Modern engines are built with finer tolerances and therefore require thinner oils - those with lower viscosity – that can also improve fuel economy by around three percent.”
Experts at CarShop advised drivers to consult their vehicle handbook to identify the recommended engine oil for optimal performance and fuel efficiency.
They explained: “This allows us to use lower viscosity oils, which take less energy to pump around the engine. Think about the energy it would take you to squeeze a bottle of water vs. syrup.
“This then translates to improved fuel economy and savings for customers. Typically, moving from a 10w40 engine oil to a 5w30 would show a fuel economy improvement of around one to two percent.”
Modern engines are designed with tighter tolerances and boast thinner oils with lower viscosity.
These require less energy to run through the engine - improving the fuel efficiency by up to three percent.
Specialists at Castrol added that lower-viscosity oils “generally enable reduced fuel consumption”.

When it comes to selecting the right oil, experts recommend to use the correct type tailored to your vehicle's model.
According to MillersOils, newer models offer oils with lower viscosity base with better lubrication to protect engine parts while boosting fuel economy.
For this, drivers are advised to consider transitioning from their old models to newer ones.
Going from a 10w40 engine oil to a 5w30 could result in around one to per cent improvement in efficiency, according to industry specialists at Castrol.
Fuel prices have surfed by around 9p per litre and have now climbed above 149.5p in just four months, according to RAC Fuel Watch.
Diesel prices haven't escaped the rise, jumping from 147.62p to 157.99p.
It comes as a motoring expert revealed a little-known trick which can help slash the amount of fuel used and therefore save you money at the pump.
Drivers across the country are feeling the squeeze with steeply rising fuel costs as the cost of living crisis continues to bite.
Elsewhere, motorists can slash their fuel use by up to 25 percent by removing one common item from their car.
Experts say that applying attaching their bikes to car roof racks could save drivers hundreds of pounds.
