Reducing your cars emissions.

Reducing your car’s emissions is a win-win. It's good for the environment, good for your wallet and good for overall car performance. 

There are some simple steps you can take to ensure you’re reducing your car's emissions and here’s a practical guide: 

Cleaning agents:

Using a cleaning agent can have a very positive impact on both car performance and on the environment. As cars age and as mileage increase over time, harmful deposits can build up in the vehicle's engine, reducing efficiency and increasing emissions.

Adding a cleaning agent into the fuel system will help remove the deposits and lower the emissions. Ideally, a fuel cleaner should be used every three months to maintain optimum efficiency.

Choose quality fuels:

While people are sometimes sceptical about expensive fuels often labelled as premium, super or deluxe, quality fuels cost more because they contain active cleaning agents to remove dirt from engines which improve fuel efficiency and reduces car emissions.

Results vary depending on make, model and age of the vehicle, but we’d suggest you try filling up three or four times to see if you notice any difference in car performance.

Check your oil and change it when needed:

Oil lubricates, cleans, cools and prevents wear on an engine. It should be changed regularly to keep your car running at optimum efficiency- even between services. Check your vehicle's handbook for the recommended service intervals and top up in line with the manufacture’s guidelines, making sure you use the correct grade of oil.

Check air filters:

When an air filter is clogged up, the airflow to the engine is reduced, which can lead to deposits building up, causing premature wear and tear.  Check the recommended service intervals for the optimum time to change the filter.

Check tyre pressure regularly:

We’ve discussed the importance of optimal tyre pressure in a previous blog, on both car performance and on fuel efficiency. According to Michelin, a tyre loses around 1 psi (0.076 bar) per month, but other factors might accelerate the leak.

Low tyre pressure increases fuel consumption and CO2 emissions.

Check your tyre pressures in line with manufacturer's recommendations or at least once a month.

Change your driving style:

Sounds dramatic – it’s not really. Slow and steady wins the race. Changing gear earlier, braking sooner and slowing down will reduce wear and tear while maintaining fuel efficiency.

Drive less:

On shorter hops, less than 5kms, consider leaving the car at home. Walking or cycling are great options. And on long trips consider carpooling. 

Maintain your cards aerodynamic efficiency:

Roof boxes, car racks and transporting heavy loads will slow you down, increase fuel consumption and reduce overall performance. For aerodynamic efficiency remove when not in use.

Upgrade your car:

And finally, the most dramatic suggestion left to last! Modern cars are more efficient than ever, with manufacturers facing increasingly stringent environmental legislation.

While these tips will reduce your emissions, upgrading your car to a more efficient model is something worth considering if you’ve the budget. Modern car manufacturers face increasingly stringent environmental legislation. And there’s a good choice of hybrids and EV’s to consider built with emissions in mind.
