Without algebra, here's what you do; Put in 3 quarts, then start the engine until the oil light goes out. Then wait a few minutes and check the dipstick. Add as much as it takes to bring it up to full. There's 2 marks on the dipstick. The bottom one is at 1 quart low and the top mark is full. Make sure your car is on level ground when you do this.Do not overfill it. I usually use Mechanic's Engine Flush right before an oil change. That removes dirt, varnish and sludge and following the instructions gets the engine hot so the dirt and oil quickly flow out.How many quarts of oil am I to add to a 99 Taurus after oil change?
Between four and five. After four, let it sit for a minute then check the dipstick. Then add a little bit of the fifth quart until you get the right level on the dipstick. Then run the engine for a couple minutes, let it sit for five, and check the dipstick one more time. Done.How many quarts of oil am I to add to a 99 Taurus after oil change?
