I signed up in 2010 when I got my Honda Insight. I stopped logging mileage about five years ago but started up again recently. My Honda just hit the 100k mark and is going strong. I am trying to be more conscious about my fuel usage and driving habits again, so here I am.
But I have no record of those five years of fill ups but I entered in two fill ups from the past few weeks. I imagine this is going to throw off my stats . . .so I am wondering if I should just keep entering new info with the 5 year gap or start over again, enter in my vehicle as a second vehicle, etc.
Welcome back! Since you're tracking by trip miles, nothing special needs to be done. If you were tracking by odometer reading, just check "I missed a fillup" on your first fill, so it does not attempt to calculate mileage on the period you were absent.
