Figures from each model’s own manufacturer documentation (spec sheets and manuals); runtime = documented tank capacity ÷ consumption at 50% load. Verify against the datasheet for your exact configuration.
Across 25 models with manufacturer data, full-load consumption runs 2.40–15.85 gal/h (median 12.57); at 50% load the median is 6.76 gal/h.
At 50% load, documented tank sizes give 0.9–67.0 hours (median 31.2 h) across 14 models.
