I daily drive my truck 8 miles to work. The 7.3 holds 8 gallons of coolant, 4 gallons of oil, and barely moves the needle on the temp gauge in the winter. No heated seats so it’s a cold ride. It’s been very dependable but noisy, Smokey, and if it breaks it would be expensive. Still 15 city, 20 freeway, 12 towing. We drive the wife’s Nissan Rogue on long trips. 35 mpg! Liking the 6.2 for smooth, quiet, brute power and since they’ve been using this engine for a long time it has a decent record. Same old f250/350.
