Re: First oil change some info and comments

Well I'm going after work tomorrow to pick up the $60 filter and $9 a quart oil (x9 qts as I always pour a new quart in after it drains for my own peace of mind) to change it myself at 9300 miles. Most expensive oil change cost of any vehicle I've ever owned, but I'm going with dealer spec'd stuff, until more brands and options come to market.

Wally World has Peak Blue Def made in January 2015, so I hope that it works out fine.

Any concerns over my plan here ladies and gentleman?? Thanks.

Rick

Re: First oil change some info and comments

anyone verify the dealer is waiting 30 minutes after refilling with Ultra Euro L? My dealer is using the correct Oil, but I know did not wait 30 after the fill to start the engine. They let the oil drain for a long time though. I requested them to allow drain time.

Well, I'm concerned that I haven't made my standard shameless plug requesting that everyone performing DIY changes do a Blackstone UOA while they're at it and post their results on this forum.

Other than that, have fun. Be sure you securely refasten your air intake hose. Might check your OEM engine air failfilter to see if the gasket is already cracked and leaking. Remember, it's easier to close the engine air filter box if you pull the lower housing toward the front of the Jeep.

I just went wtf? You wait 30 minutes after the oil is filled before you start the engine? For what? Cows to come home.

Cows to come home, and to follow spec (well, a 15 minute wait anyway).

WARNING: Any time the oil is drained and filled it is critical to wait 15 minutes before starting the engine.

NOTE: It may take 30 minutes or longer for the engine oil in the oil filter housing to completely drain back into the engine.
With the emphasis on "or longer". It's still dripping slowly after an hour, but it takes longer than 30 minutes for even the filter housing to drain through the sump.

You're always going to have some residual oil in the pan no matter what you do, once it starts dripping, plug goes back in.

Why rush? We're waiting for cows to come home after we refill anyway.

I say wait until after the filter housing drains. That happens *after* the pan starts dripping... 30+ minutes, as per spec. You could time it on the clock, but it's simple to visually assess whether the housing has or has not yet drained.

It's always advisable to wait after you filled oil. Most engines fill oil from the top. The oil has to flow by gravity through the oil galleries to get to the oil pan all the way at the bottom of the engine. The pan acts as the engine oil reservoir and the engine oil pump is pulling the oil from there. If there is little oil in the pan and you start the engine, you risk starving parts of the power plant that require lubrication. Engine manufacturers experiment with worst case scenarios where the oil is cold and thick and come up with the time it takes for it to fill the pan to a safe level, and that's your spec.

Well got it done, very easy oil change with that top mounted filter housing. I waited 30 mins or more, and I always pour a new quart of oil in after the drip starts just to flush a little extra of the dirty stuff. Wasteful probably, but gives me peace of mind and been doing it for 25 years. Also added 5 gallons of peak blue def that was made last month according to the label. No problems with the engine life reset and a 15 min test drive. Thanks for the info on here.

I'm thinking it would likely be not just about getting the level correct. It won't be anyway, till the engine has run and oil filter etc filled.

The wait would almost certainly be for allowing the oil to prime the pump.
After a long sit to drain the engine properly, there will be very little oil anywhere in the engine, including the oil pump. So when you turn the key, without an appropriate wait, the engine will run without oil pressure for a while. (And only then after filling the oil filter by running the engine, can you be sure to get the level right.)

ie: I would say they stipulate a "sit" period before starting the engine for good reason, (pump priming) and it wouldn't be about getting the level right. You simply can't do that without running the engine first!

I measure the oil carefully when filling to get it right anyway, otherwise you risk overfilling which is a PITA if you don't have a vacuum oil extractor.

Nope, oil pump doesn't prime itself. Have to spin it. Some industrial engines have an electric primer pump. I've used an oil tank, with compressed air as a primer for a new engine before.

I've seen up to a quart of oil in an engine after taking the sump off. Lot of pans have baffles.

Basically just drain it, fill it, run it, then check it the next morning if you're really concerned about the oil level.
