High idling has been a contentious issue in the trucking industry for many years, and it’s not always easy to decide whether or not it’s the right choice. High idling is when a semi truck is left running while parked, typically used to keep the engine, cab, and sleeper warm during cold weather. Some drivers choose to high idle because it’s more comfortable than waiting in an unheated cab and because they fear the added strain of cold-starting an engine. But does this practice pay off?
High idling can be beneficial for short-term comfort and convenience but there are drawbacks that might make it a poor long-term choice. First, there are environmental concerns. Idling engines produce emissions that can be harmful to humans and wildlife. In addition, leaving your engine running can use up to a gallon of fuel per hour which adds up quickly over time. There are also battery drainage issues caused by high idling that can reduce a vehicle’s lifespan.
The Pros
- Convenience — No need to wait in an unheated cab
- Reduced engine strain — Cold-starting an engine can be hard on it
- Potential fuel savings —High idling may reduce wear on diesel particulate filters (DPFs)
The Cons
- Environmental pollution — Idling engines produce emissions.
- Fuel consumption — High idling uses up to a gallon of fuel per hour.
- Battery drainage — High idle drains batteries faster than normal use.
Ultimately, whether or not you should high idle your semi truck depends on your individual circumstances. If you’re planning on being parked for several hours or overnight in cold weather, then high idling may be worth considering as it could provide additional comfort and convenience.
However, if you’re only going to be stopped for a short time then it’s probably best to turn off your engine as the costs associated with running it outweigh the benefits.
Conclusion: Should I High Idle My Semi Truck?
It depends on your individual circumstances – if you plan to be stopped for several hours in cold weather then high idling may provide additional comfort and convenience but if you will only be stopped for a short time then turning off your engine is likely the better option due to environmental pollution and fuel consumption concerns.
