Cut my fleet's fuel cost per mile
Finds where fuel is being wasted by driver, truck, and route, and builds a plan covering idling, speed, purchasing, and fraud controls.
The prompt
Help me reduce fuel cost across my fleet.
Fleet: [NUMBER AND TYPE OF UNITS, MODEL YEARS, FUEL TYPE]
Fuel data: [PASTE - by unit or driver: miles, gallons or liters, MPG, idle hours, average speed, fuel card transactions]
Fuel purchasing: [retail at the pump, discount network, bulk tank on site, fuel card program]
Current fuel cost per mile: [AMOUNT]
Operation: [long haul, regional, urban delivery, reefer loads]
Tools we have: [telematics, speed governors, APUs, idle shutdown, tire pressure systems, aerodynamic kits]
Fuel surcharge: [do we recover fuel through a surcharge program, and how is it calculated?]
Analyze:
1. MPG spread by driver and by unit, adjusted where possible for route and load type so I compare like with like.
2. Idle time and its cost.
3. Speed: share of time above the efficient range.
4. Purchasing: price paid versus available network discounts, out-of-network purchases.
5. Fuel card red flags: purchases exceeding tank capacity, fills far from the truck's GPS location, frequent small fills, off-hours purchases.
6. Whether our surcharge fully recovers fuel cost increases.
Return:
- A savings table: Lever | Current state | Target | Estimated annual savings | Cost to implement | Owner.
- A driver fuel incentive idea that rewards improvement fairly, without encouraging unsafe or illegal behavior.
- 5 monthly metrics to track.
Only calculate from my data; mark estimates [ESTIMATE]. Treat fuel card anomalies as items to verify, not proof of theft.
Highlighted [brackets] are blanks to replace with your own details.

How this prompt is built
This prompt follows the RTF structure (Role, Task, Format). RTF tells the model who to be, what to do and what shape the answer should take. It is the quickest structure that still gives noticeably better results than a bare request.
