Simple Rainwater Harvesting Formula-For every 1â of rain and 1,000 square feet of impermeable surface (roof, driveway, etc), about 620 gallons are generated. Meaning, you can capture about .62 gallons per sq ft. To figure out the square footage of a surface, multiply the width x length.

Synthetic Oil for cars (How many miles can you really go on it before changing it) I usually get Synthetic oil for my vehicle so that I don't have to change the oil every 3000-3500 miles. Now I go around 5500-6000 miles on Synthetic oil. However, I noticed as I went to the gas station that for Mobile Oil (synthetic) that it says you can drive your car for 1 year or 15,000 miles on it, whichever comes first.
