Sometimes getting away with it may just mean shortening the life on the back end. I dont know how many miles you usually put on your vehicles, if you’re trading in with 100-150k regularly it may not make a difference. I rarely get rid of a car before 200k, and have driven a few well over 250k, I went over 300k on one. I attribute a lot of this to regular oil changes with quality filters and synthetic oils. I also never go more than 7500k on an interval, even if the manufacturer interval is longer than that. I do 5000 on most.
