For those of you who still believe dealer oil changes are superior to DIY...

I recently had my EcoDiesel in the shop for a timing chain cover gasket leak. Quite an involved repair. Anyway, I got my Jeep back last month... it only had about 5 months/3,000 miles on the Mobil 1 ESP oil going into the shop. Service writer told me they were going to reuse my oil (i.e. just add it back after the repair).

I wasn't convinced. Also, with them messing around with the engine and all, I really wasn't comfortable going the full 12 months/10k miles before a change. Seemed like I might have more particulates kicked up. Therefore, I changed it out today.

How much oil did I drain from my Jeep today? No less than 9 quarts of god knows what kind of oil. Thanks, dealer techs. "More must be better, amirite?!"

I'm deliberately trying to ignore what other guidelines the techs might have ignored during the repair. I'll never voluntarily allow a dealer to change my oil again. Even a free oil change isn't worth the potential damage they might wreak.

I feel the same way. Oil changes are done by the most unskilled people in the whole place, probably high school students on a summer job that could care less. They dont waste skilled mechanics hourly rates on oil changes. The majority will be done fine but i have read too many stories about botched oil changes and i dont want to be one. I am happy to spend the 20 minutes twice a year doing it.

Haha, it takes far longer than that. Spec in the service manual is 30+ minutes for draining, followed by 15+ minutes after adding the new oil to allow it to disperse. Of course, I feel much better knowing it was done correctly so the time involvement is no issue. I'm sure the dealers would *never* try to cut corners on those specified wait times. Right?

I didn't mention in the OP that I think they overtorqued my filter housing. Hard as hell to get off, and the plastic nut is marred around the base when it certainly wasn't before. Wouldn't be surprised if some bastard used an impact wrench and/or the wrong socket.

I cant speak for what a diesel might take. 20 minutes is what it takes me on the v8, amazon drops oil on front porch, fumoto valve drops the old oil right in the jug, jug goes to auto parts store next time im there no mess quick and easy and most of all i know its done right. Or i could sit around the dealer, for for a few hours, pay more and cross my fingers while their lowest skilled people hack up my jeep.

Installed a Fumoto (aka Qwikdrain Valve) to make it REALLY easy peasy!
Don't even need ramps to do it......

Who in the world would think that? Must be some really unskilled people out there...

Yep, it's 30 minutes of oil drain, minimum allowable time per service manual, plus 15 minutes of wait for oil to migrate through the sump, minimum allowable after the oil is refilled, also per service manual.

It seems many dealer techs don't follow these requirements in order to cut the time in the bay.

Or just old and too tired.

For many years nobody touched my car, nor my wife's car but me, except for tires and wheel alignments. I even did my own warranty work and got reimbursed from the dealer.

Then, to make up for screwing up the paperwork when I was picking up a new Chevy, the owner of the dealership gave me 3 years of free maintenance. After that I couldn't bring myself to crawl under a car again. I figure whatever they may destroy they will fix or replace.

Exactly, AND the air suspenders give you plenty of working room.

Re: For those of you who still believe dealer oil changes are superior to DIY...

I have always changed my own oil with very few exceptions. I have access to the Auto Hobby Shop on base which is a drive on drive off lift. I can change my BMW in 20 minutes longer with our diesel given the longer change time.


One huge caution. If you change your oil in the summer time and have no cool down time be careful. Oil coming out of the sump is well north of 220F and will scald you and burn you bad. I learned this on my BMW 335 which runs 245F oil temps. Our Jeep diesel isn't much cooler.


By the way I have tried it both ways when the oil is hot waiting the 30 mins and waiting about 10 mins. I could not notice any difference to be totally honest and I am able to watch what drains out of the sump into the drain can. YMMV...

Good point about hot oil, and another aspect in favor of the QwikValve. One finger on a lever, above the oil flow.

Another caution is that the exhaust system remains hot for hours and your skin won't like being introduced to it. I had the Jeep on OR2 (jack stands!) and was on an uncooperative creeper trying to jockey into position and brushed against the exhaust. The Jeep had been parked for two hours at that point.

I definitely can. The first time I changed the oil the filter housing didn't even *begin* to drain until the 35 minute mark. Until then it was just a pool of oil. It was summer, BTW, and the oil was definitely warmed up.

I just go about other tasks and let it sit and drain.

Re: For those of you who still believe dealer oil changes are superior to DIY...

I had a shop screw up an oil change before. This was years ago, at Sears in Tanforan, San Bruno CA. MORONS.

I also had another shop screw up a radiator flush-and-fill: they drained it but then they never filled it. They said she was all ready, I paid and drove away, and watched my temp needle climb. Within only a couple of minutes the temp was high and I was back at the shop. A small shop, I went into the bay to see what was wrong, and my radiator was empty. More MORONS.

As the saying goes, if you want something done right you have to do it yourself.

Thanks to the guys who pointed out the Fumoto drain valve. I'll be ordering one.

Also, where do I find the JGC CRD's oil change procedure with the wait times and all that?

Thanks in advance.
