Well, MY truck has 12,000 miles and hasn't used any oil to date. Dealer changed at 3,000, and 7,500 miles - won't be able to get into the shop for a while longer this time. Dipstick still shows at the top notch, right where it is when I check it after the drive home from the shop.
Maybe I'm doing something wrong? According to other postings, it should be down 2 quarts by now.
Haven't had a chance to tow anything with it yet, however, it did get a hard break-in run from Texas to New York in 26 hours with only 1,000 miles on it when new. Figured the extended time at high temperature seated everything quickly. I didn't drive it like it was stolen, but didn't baby it either. Runs great, averaged 24 mpg on that drive. Still getting around 18.5 up here with mixed highway and 2 lane mountain roads around West Point. No tick, no smoke, but the oil does look a little dirty now. Using factory filters and whatever oil the dealer puts in, at least it's 15w-40! I need to get a Fumoto drain valve so I can change it myself, then be able to measure how much comes out compared to what goes in. Dealer just drains it into a huge drum, no way to measure quantity.
Hope nothing changes, I feel pretty lucky so far!
