Ford, Volkswagen and Porsche, for example, recommend oil changes every 10,000 miles. So does Toyota on several engines, including the Prius' 1.8-liter four-cylinder and the Camry's 2.5-liter four-cylinder. BMW says owners can go up to 15,000 miles between oil changes (with synthetic oil).
âHighâ fitness women ran the mile in nine minutes or less; âmoderateâ fitness women ran it in 10 minutes and 30 seconds or less and âlowâ fitness women needed 12 minutes or more to complete the mile. Run for Life states that a 10-minute mile rate is good for beginners; the goal is to complete 3 miles in 30 minutes. If a 10-minute mile rate seems out of reach, start with a 12-minute rate and then work downward.
According to your age will also depend on the timed run. For instance say someone is 18 maybe you would be expected to do a mile in 6 minutes. If you are say 30, might be expected to do a mile in 15 minutes(these are just guesses). When I was in the Academy in 1971 I did a mile in 6 minutes. Things have changed drastically since then. last I heard on the mile run for an 18-22yr old was a 6.5 min. mile.
