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.
That synthetic oil gets changed at 7,000 miles. But regular conventional oil must be changed every 3,000 miles. My local mechanic that I go to is the the most trustworthy mechanic around. I asked him what if I go 5,000 miles between oil changes.He said, you will ruin your engine eventually.ut regular conventional oil must be changed every 3,000 miles.

I know the regular oil they tell you to change it at 3k miles but im pretty sure its ok to go to 4 or even 5k miles, yes? SO im wondering about synthetic oil in my 2012 corolla and how many miles is safe to go over without changing it You could change 100% synthetic oil at 6-9k miles and not have a problem (synthetic blends and regular dino oil at less mileage).
