Oil Change - By Computer or Mileage?

So, I have been reading a couple of the more recent threads related to Oil Changes as well as other general oil topics here and other places.

As my vehicle has 9k on the Odo and is still saying it has 15% oil life left I am starting to be concerned that I need to change it. I know the vehicle is suppose to be okay with 10k oil changes but it seems as though the computer is thinking I have more life left than that.

Is anyone finding the computer telling them higher than 10k is okay? Would that be the drop dead line you guys would be willing to go?

Is anyone finding that dealerships are doing an okay job? How much is the price difference at now? I know a few months back the price to do it at home was close to just having the dealership do it.

Re: Oil Change - By Computer or Mileage?

Haha, there is practically no way your question will *not* devolve into a rehash of the "how often should I change my oil?" debate.

However, per the diesel supplement, page 82:
Quote:
NOTE: Under no circumstances should oil change intervals exceed 10,000 miles (16,000 km) or twelve months, whichever comes first.
That's your canonical answer.

I'm comfortable going the full distance the algorithm indicates, given the Blackstone UOA's that have been posted on this forum so far. I'll be taking another one when I change my almost-10k-miles-old oil this week and I expect it will still show adequate TBN left in the oil.

I do my own oil changes because I don't trust the dealer techs to follow the prescribed protocol. I'm not sure there is any cost savings to do it myself, as this latest DIY change will cost about $115. Hell, the dealer might even be less expensive than that, but what price is peace of mind? I'd rather know it was done correctly than save a few pennies by going to the dealer.

Re: Oil Change - By Computer or Mileage?

I do not think that I have seen very many comments where the display said that an oil change was needed at a mileage greater than 10K. Seems most comments and my experience is that it says a change is needed thousands less than 10k. I drive nearly all highway miles and very little stop and go yet it wanted me to make an oil change at 8.5K.

From all that I read I would not be concerned going greater than 10K on synthetic oil at least as far as what negative impact it might have on the engine. There are people on this site more knowledgeable than I am but all the threads I read on synthetic oil is that it usually does not start breaking down even at 10K. On the VW site some even talk about just changing the filter as it is the particles that might be in the oil that would cause damage more than a failure of the oil.

If you drive lots of stop and go you might not want to go over 10K but that is more just personal opinion than based on some specific knowledge.

I was aware of that statement so I felt like it should be the end all threshold. Just wasn't sure anyone had done it by the computer.

I will have to find the posts on other's Blackstone UOA's. I will be doing one as I change the oil to see how my engine is holding up as well.

Did you do one of the Kit's from the Mopar sites or did you do Mobile 1 from a local parts store and an OEM filter?

A while back I kept up with people having to do changes mostly around the 6.5k mark it seemed.

Mine spends about 97% of its time on the highway doing 55mph+. I drove it this morning instead of my TDI Golf and it crossed 9k miles while showing 16% remaining oil life.

I guess I should also add that my vehicle has never been updated or flashed since being purchased. Never been back to the dealer for anything, even though I have a list of ~7 items that need to be looked at or fixed.

Re: Oil Change - By Computer or Mileage?

I got an OEM filter off eBay both times. I don't believe there are any aftermarket options.

The first changed oil (currently in the Jeep) is the Pennzoil Ultra Euro L 5W-30; bought on Amazon Prime. However, this time I am going to use Mobil 1 ESP 5W-30, which I got locally from Napa Auto Parts... which was about the best price.

I would propose the caveat that going farther than 10k on an oil change is in contravention of the manual and thus is not a good plan while the warranty or extended service contract (if applicable) is active.

I agree, 10k will be my limit.

Re: Oil Change - By Computer or Mileage?

I have question, I have seen some comments that dealers said the oil in the Eco does not need to be synth but regular oil is fine, what is your take on that? kinda confused about my first change coming up. Maybe I should RTFM! but wanted to have input from you guys…..TIA.

No, absolutely not, if you value your warranty or fuel economy. That comment was made in the wrong forum.

The oil for an EcoDiesel must meet the MS-11106 specification. In the US there are basically two specific oil products that meet this spec. In the US one can expect to pay $7 to $10 per quart x 8 quarts, and expect to pay $40 for the oil filter paper cartridge.

There are also specific procedures that must be carefully followed when changing the oil; this is either a job for a conscientious, educated DIY owner or a competent dealer. You will never be able to take an EcoDiesel to a quick lube type place.

Re: Oil Change - By Computer or Mileage?

Thanks for the feedback, I have been calling a few local dealers, and it seems like if I bought a rocket ship and no ones has a clue on how to service it.....When I ask for pricing on an oil change, one dealer asked for the VIN number, one told me ...euhhhh about $250....not sure....an other told me that they need to check and would get back to me....these are all dealers in Canada, next to my home... then I decided to call a dealer in Plattsburg NY, which is about 20 minutes away...they put me on hold and came back saying the price was $99.95....so, I am pretty freaking confused....I know for a fact that the dealers in the US had always charged me way less then the ones up here...My HEMi GC 2011, locals would charge $85 and in the US $29.99....so when they told me $99 bucks for my 2014 Oiler, I just cant imagine this is for synth oil...How would I find a serious dealer that knows something about Diesel's?????

$99 USD isn't unreasonable. It's approximately the DIY price (your time is free) using the less expensive Pennzoil; presumably the dealer can get a better deal on filter cartridges than we can and can buy oil in bulk.

You just have to trust them to follow the instructions. I know in my case I had to wait *far longer* than the specified time for my system to drain, and I don't trust the dealer techs to wait even the 30 minutes the procedure indicates.
