8 gal vs 15 gal vs 20 gal oil drain pan classes
Compare oil drain pan class ceilings against OilDrain estimates, with verified VEVOR US product examples and an honest NO_MATCH path.
| Class | Clears required up to | Typical fit | Trade-off |
|---|---|---|---|
| 8 gallon | 8 gal required | Light DIY capture (e.g. 5 qt × 4 jobs = 5 gal) | Too small for multi-job truck/shop volumes |
| 15 gallon | 15 gal required | Heavier DIY or light shop loads that clear 8 but stay under 15 | Still short of large multi-vehicle capture |
| 20 gallon | 20 gal required | Shop loads whose required gallons exceed 15 but stay ≤ 20 | Verify live listing; above this ceiling → NO_MATCH |
| NO_MATCH (above 20) | >20 gal required | Loads whose required capacity exceeds this ladder | Do not force a 20 gal class — empty sooner or size up |
