A recent initiative supported by Shell and the North American Council for Freight Efficiency demonstrated how driver behaviors significantly influence the fuel efficiency of diesel trucks, even with the latest automated transmissions. Here are key habits that can help reduce fuel consumption and lower carbon emissions:

1. Limit Top Speed: Speed increases air resistance, which in turn reduces fuel economy. Each mile per hour (1.6kmph) over 88 kmph is estimated to reduce fuel economy by 0.42 to 0.85 km/litre.
2. Control RPM: Efficient driving involves maintaining low RPMs and high torques, which helps minimize internal engine friction and fuel usage.
3. Economical Route Planning: Avoiding routes with hills and maximizing cruising on straight roads can significantly enhance fuel efficiency.
4. Minimize Idling: Modern trucks have many in-cab accessories that drain fuel if the engine idles too long. Utilizing alternative power sources for these accessories or optimizing cabin conditions can reduce fuel consumption.
5. Smooth Driving: Anticipating road conditions and adjusting speed gradually instead of abruptly stopping and starting can save fuel and reduce truck wear.

These simple yet effective changes in driving habits can lead to significant savings and environmental benefits. Additionally, lower viscosity engine oils like Shell Rotella T5 10W-30 can improve fuel efficiency compared to traditional SAE 15W-40 oils. The Shell Rotella® Lubrication Limited Warranty covers Class 1, Class 2 through Class 8 vehicles with heavy duty diesel engines used in on-road applications. When registered, this warranty provides coverage for repair or replacement of certain heavy duty engine parts that fail on account of engine wear or which experience abnormal wear, because Shell Rotella® heavy duty diesel engine oil failed to provide proper lubrication.

Currently, you can earn up to $80 in Mastercard® Virtual Reward Cards when you purchase Rotella® T4, T5, or T6 before May 31, 2025. Check out this promotion on the Shell Rotella website.
