Here's my DEF maintenance plan...
Drive a minimum of 12-15,000 miles a year. Run the DEF down until the warning appears. Fill ONLY the passive tank. After the DEF warning disappears, top up ONLY the passive tank. If the total DEF added is at least 5 gals., leave well enough alone

p.s. I almost forgot the most important step. Tell my SA that removing the DEF filler caps will detonate gel explosives in the spare tire.
