Maintenance intervals are not being tracked correctly

[greggammon]

Hi,
Fuelly is working great for fuel mileage tracking for me but my maintenance intervals don’t seem to be tracking correctly. For instance today my air filter was overdue by ~5,000 miles In my 98 ranger according to Fuelly. I replaced my air filter on my 98 Ranger. I have air filter reminders set for 20,000 miles or 3years. Now when I enter the air filter change and odometer reading into fuelly it tells me my next change is due in 14,749 miles or 22 months.

Is fuelly counting the back mileage on the old air filter towards my new one?

It certainly looks like it.

I have other funky things happening too. For instance, I change engine oil every 4000mi or 6 mo. I changed the oil at 243,000 miles and Fuelly tells me my next changes is due at 256,000 miles. Is it possible my data got corrupted?
