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.

If you have been doing short trips in town you will need shorter oil change intervals than if you are driving on the freeway a lot. It also depends on the type of oil. Synthetic oil will go a lot longer than mineral oil without sludging. What you don't say is 1000 miles past what - how many miles it has actually been. If you are up to 4000 miles now it is no big deal. If you are up to 11000 miles now (some cars, especially in Europe, are going to 10K mile intervals) that is a bit much. My Prius sedan has 7500 mile intervals, 5000 in severe conditions.
