Just bought a new 2013 from Vernon auto group in texas. They put a lifetime no deductible warranty on all their vehicles with the stipulation that all maintaince is done at selling dealer or pre-approved service provider. The warranty is supposed to cover everything-injectors, turbo etc. With longer mileage service intervals, would it be worth it just to let dealer/other service provider do maintaince or would I save more doing my own maintaince as usual. I'll probably drive 30K miles a year and keep the truck for 10 years. Thanks
