B&K Tank Oil Tank Measuring Stick 4 Fold to 126″

I considered getting an expensive (as in $150) reader which connects to your phone, and gives you the exact amount of gallons left.But I am broke and don’t want to spend that much, so I found this. It works great! I printed out a chart for 275 gallon tank (yours may be different). It lists the inches and the amount of gallons left. Super simple. I measure once every 3 months during the winter, so taking the time to manually check isn’t s big deal at all to me. Takes me maybe 5 minutes to check. It works.
