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.
Having said that, fitness levels vary greatly when it comes to beginners. Josh Clark from Cool Running says a man who is in shape who typically runs 15 to 30 miles per week can expect to post a 10K time of about 48 minutes, while a woman will run the same distance in 58 minutes.
