Which is the economy mode, E or P for trucks?
2 Answers
E stands for Economy mode, while P mode represents Power mode or Heavy-duty operation mode. P mode is primarily designed for high workload operations, whereas E mode balances both workload and fuel consumption. In P mode, both engine speed and pump flow rate are significantly higher, resulting in relatively greater fuel consumption. E mode reduces the main pump flow rate to some extent, aiming for lower fuel consumption, and is generally the preferred mode for routine operations. Additional Information: 1. P mode refers to Power mode or Heavy-duty operation mode, where both engine speed and pump flow rate are set high to prioritize heavy workloads, consequently leading to relatively higher fuel consumption. 2. E mode denotes Economy mode, which balances workload and fuel consumption, typically operating at 80%-90% power capacity. The main pump flow rate is partially reduced in this mode to achieve lower fuel consumption, making it the standard choice for general operations.
I've been driving trucks for long-distance hauls for over a decade, so I'm very familiar with the mode settings on the transmission. The 'e' stands for economy mode. After starting the engine and switching to 'e', the truck runs more smoothly and fuel-efficiently because the engine maintains lower RPMs, resulting in noticeably reduced fuel consumption. 'P' is the parking mode, used only when coming to a complete stop to lock the wheels and prevent rolling. On highways or in congested city traffic, I always use 'e' mode, especially when the truck is empty—it works even better then. Once, I forgot to switch to 'e' and ended up burning significantly more fuel over a 200-kilometer trip, which I deeply regretted. Economy mode also reduces engine wear and extends its lifespan. I recommend making it a habit to shift the lever to 'e' right after starting the engine. Don’t underestimate this choice—it can save you a lot of money over time. Regularly checking the transmission fluid to ensure smooth mode switching is also essential. Overall, 'e' is a great fuel-saving assistant, while 'p' is purely for parking.
