dry sump question

[red rocket]

Hi i just bought a 3 stage dry sump system that holds 12 Quarts of oil and i was just wondering how many laps you can put on the oil before it needs to be changed.

any help would be greatly appreciated

Depends on the type of oil you use..We run a 5 stage dry sump and have filters for debris between pan and pump and then pump to return tank and then 2 quart paper between pump and cooler...run XP-3 and 12-14 races before changing...We change 2 qt filter every 3 races on top off...bearings look great...
