Why is my grill using so much propane?
Quick answer
Grills use extra propane when all burners run on high for long preheats, regulators deliver unstable pressure, burners are clogged (causing longer cook times), or hoses leak slowly. Cold weather also increases consumption because preheat takes longer — not always because the tank is defective.
Check for leaks first
Soapy water on hose, valve, and manifold joints — bubbles mean fuel loss 24/7, not just while cooking.
Usage habits
- Long lid-open preheats in winter
- Running side burner constantly
- Under-sized tank for high-BTU built-in grill running all zones
