I'm 62 and I've changed oil by myself, on every single vehicle I've owned, for my whole life. At one point we had 5 vehicles (now down to 4), so I'm underneath any one of the vehicles pretty regularly. Here's my feelings/explanation. First, on an expensive purchase like a vehicle, and the importance of good lubrication - especially on the 5.7L Hemi, I'm not really going to leave it to whomever happens to be available on any given visit to the dealership to change my oil and filter. Obviously there are some great mechanics working at the dealerships, and then some not so great. I've seen/heard way too many stories and/or disasters that happened at the dealership while a vehicle is being serviced - and when you drive away, you might think everything is good, until days/weeks/months later. Next, I actually enjoy servicing my vehicles. It's therapeutic for me. I myself am an engineer (in the healthcare industry) and perhaps as a result, I am very picky, maybe OCD, about how my vehicles are serviced. When it comes to oil changes - I like to drain as much as possible of the old oil - so I'll start the oil draining, and come back an hour later - if it's still dripping out, I'll wait another hour. Second, I'm picky about actual oil and filters. I use Redline, since day 1 on most vehicles (certainly the 5.7L Hemi) - and I just can't get the dealer to put that Redline oil in for me. Yes, the Engineers screwed up on "serviceability" when it comes to oil changes, but not really that big of a deal. Many bigger problems in life than figuring out how to changing the oil, and also, many ways to avoid a mess. I'm thinking that maybe when I'm 80, I'll start paying someone to do the oil changes, but definitely, definitely not a dealer ... just been around too long, seen too much. But in the end, to each his (or her) own - whatever works for you and whatever you're comfortable with! Cheers!
