Let's be honest here: you are advising ignoring the manufacturer service instructions for changing the oil. You also choose to run non-MS-11106 spec/high-ash oil in your EcoDiesel in contravention of the owner's manual. These things are your choice as it's your vehicle, but you really should add disclaimers about your perspective in case others come here looking for advice and aren't interested in potentially warranty-voiding procedures.

So, if people wish to follow the EcoDiesel service manual instructions, they can wait the 30+ minutes for the filter housing to drain and later wait 15 minutes after filling the oil before starting the engine (which Chrysler indicated was a "critical" step).

Or, they can ignore Chrysler's instructions, follow your contradictory advice instead, and hope for the best.

Re: First oil change some info and comments

Is the 30 minute drain wait mentioned in the manual or instructions?

I know the 15 minute wait after filling is and so I would never ignore that.

Also, are you guys running a drain plug gasket of any sort? where did you get a replacement from?

Thanks.

WK2Jeeps.com to the rescue: WK2 Maintenance information and schedules (scroll down to the 3.0 V6 CRD section).

There's also a Chrysler service bulletin linked from there that discusses the 30 minute wait.

Interesting...I thought the drain plug was 13mm? The F106 is advertised at 14mm?

Re: First oil change some info and comments

I did an oil change yesterday. Too easy!
Only 5,000klms in 6 months but I'd rather "over" do it on this high tech engine.

I drained the oil (nice and hot), using protective gloves just in case. Didn't spill a drop, the plug is 13mm but a 1/2" AF socket is actually a tighter fit, so I used that.
Opened the oil filter housing JUST enough to crack the seal on the large O-ring, then went and did other things for a good hour or so to let sump and filter to drain thoroughly.

Came back, refitted the sump plug (with a new O ring seal), cleaned the last few mls out of the filter housing with a clean rag and installed the new filter, then added 7.5 litres of the correct Mobil 1 ESP 5w-30 spec oil measured ACCURATELY, and again did other things for a good half hour or more.
(Buy yourself a good measuring jug with accurate measurements for the purpose.)
Started the engine, almost instant oil pressure, ran for a minute to bleed any air anywhere, then shut down and let it all settle for 15 minutes, checked the oil level, just barely a whisker low, so added the last 0.2 litre of oil.
Right on the correct spot on the dipstick this morning!

IMHO, The specified wait after filling can only be for priming the oil pickup- you can't check oil levels till the engine has been run. In any event, I'm happy to wait the time as specified and more.

Next time I'll just accurately measure the 7.7 litres right from the beginning.

One of the easiest oil changes I've done on any vehicle!

Much cheaper than being done at the dealer, (cheaper oil, cheaper filter, cheaper labour LOL) more thorough job and I know it's done EXACTLY right, with the correct oil. (I wouldn't trust most dealers not to cut corners! They're under time pressure, I'm not.)
The prices many dealers charge are pure extortion, even to the extent of charging for a new sump plug! Ridiculous- I've never, ever changed a sump plug on any vehicle, ever, and certainly not going to start now. Use the right tools, and the sump plug will not get damaged. A new seal is cheap, (and I'm not convinced even that is necessary except occasionally, however this time I used one.)

PS WRT Warranty, My son's mate is a certified mechanic, he'll happily sign the log books for me.

Re: First oil change some info and comments

Road kill. When I click on the link it gives me "about: Blank" So I don't get to see the data.
Do you know what page in the manual that data is. Is it in the Diesel supplement?
Thank You

I neglected to add, although others have already, that to get at the oil filter you loosen two hose clamps and remove the flexible air inlet duct. Very easy.

And while I'm at it, the air inlet box downstream of the PCV inlet has far less oil since I added the catch can on the PCV vent hose. -I should have taken photos.
Prior to that it was literally very wet with oil, whereas now there is just the finest film of oil, just barely noticeable when wiped with a clean white rag.

PPS I had a little trouble resetting the oil change indicator, repeatedly tried using the "export" version method, (ignition on, then brake pedal presses) no joy. Then just used the listed "push button start" method, ie: ignition on and three accelerator pedal presses within ten seconds, worked first time.

Re: First oil change some info and comments

I agree, it's very easy. Although most oil changes are.

Anyone with a minimum amount of mechanical experience, and a moderate amount of common sense, can do it.

Re: First oil change some info and comments

I'm wondering how you are jacking / lifting your GC's to change oil or rotate wheels/tires. With unit body construction the lift points are critical to not damaging the chassis/frame. On my Rubicon I just lift under the live axles - easy! But on my new GC Summit Diesel I'm concerned about lift points for wheel rotation. For my oil change I just lifted the air suspension to max and then drove onto four old pieces of wooden support beam - easy again. But to rotate tires I need to lift two wheels at a time diagonally. I usually use my 2 hyrdraulic lift jacks, but would like to know where and how to position under the vehicle. My last GC with a Hemi I just used the factory jack but by the time I was finished it was bordering on needing replacement - single use only I'd say, cheap and nasty.
Any thoughts on jack points or an adapter that allows you to use the factory jack points would be most appreciated!
Also the oil reset - press accel pedal slowly 3X in 10 secs. - does not work for me, is the - depress accel pedal fully for 30 secs while also depressing brake pedal 6X - the correct procedure for the diesel GC??
Many thanks for any thoughts!
Chris
