6000 miles in 9 months = 22 miles a day or 154mi. a week so the 2 mile a day trips would have to be followed by 18 additional miles each day for 7 days a week and that is enough to warm up the oil right? This really scares me though. My GF used to go to Firestone for her oil changes. I always wondered why they were only $11.99
