My car is about 18 months old, about 8,900 miles and the oil life is at 19% again.
This is the third oil change in less than 9,000 miles.
And the oil containers all claim good for 12,000 miles. Though i never would.
My 2016 XTS oil life would just about always hit 6,000 and 20%.

I may look into an XT5.

Are you changing oil if you are you need to reset oil monitor after change if you're not changing oil whoever is needs to reset oil monitor. I would say.

 

On the XT5, what is the average miles on the Oil Life Monitor.
Both motors.
Escalade is killing me. Every 3,000 miles, And thats an 8 quart job.

Oh yes, Im disabled, so I take it in to the dealer. He does rest that.
And washes the car. Anything else, who knows? I hope so. I have an eight year GM warranty.

You need to bring this up with dealer that changes your oil something is not right either they aren't resetting monitor or there is something wrong with monitor system. They have the history of service and can see there is a problem and really if they didn't reset monitor, they owe you an oil change.

 

Did you follow the vehicles break in recommendation?
Do you check the oil level in between oil changes? Do you ever need to add oil?

You bought a $80,000 dollar Escalade and an oil change every 6 months in killing you?[emoji848]
It can’t be that bad, can it?

 

No, $104,000 Escalade. And poor choice of words, not killing me, but really makes no sense.
My 2016 XTS hit 20% oil life with 6,000 miles. Every time.
All my cars, needed or not, 5,000 miles.
But, look at the oil containers today, they claim 12,000 that's crazy.

 

All I can think of is maybe you do alot of city driving & short trips and a big vehicle like that isn’t really ideal for short trips and stop & go traffic but rather long highway trips with fewer stops?

I’ve also heard that a vehicles 1st couple of oil changes should be done more frequently than normal, I think it has something to do with the break in period or something along those lines. I could be wrong though.

I don't think that is what the manual recommends, but I think it's wise to change out the first oil change more soon. I don't think the OLM factors break-in into it's algorithm.

 

You can sign up for the MyCadillac app for your phone or PC. Once you get it set up with your name and VIN you can request a vehicle status report.

There’s a section on the oil life remaining of the app page to switch from normal duty to severe duty oil changes. I’d check that to see if someone at the dealer had changed your oil change frequency.

The following is based on the numbers you gave for your XTS; which used up 80% oil life in 6000 miles = 75 miles (approximately) per 1% oil life used. So 8,900 miles divided by 75 = 118 approximately which says you should be past 0% oil life left instead of 19%. Based on those numbers your ride is doing extremely well! Seems doubtful there should be 19% oil life left...but you never know - two different models.
Your XTS @ 6000 miles and 20% oil life left is pretty close to what I get in my XTS. With mostly highway driving I use 1% of oil life per about 122 km (but I get close to redline on each merge, and I'm somewhat heavy footed off the line which uses up more oil life). 8900 miles =14323 km (approximately) divided by 122 = 116 (rounded off), so I would be past 0% oil life left as well. Hope I did the above calculations correctly...it's early am, lol.

I would not go by what the oil container says. The OLM is very good at factoring percent of oil life left which is based on many factors such as environment, driving style, city vs highway, down time when the car is not driven. I don't think it goes by the type of oil used, but I would think it is expected one would use the recommended oil - so I guess it might use that in it's algorithm.

I think you missed the part where he said this’ll be his 3rd oil change?

 

I spoke to your OLM figures in the Escalade Forum (now merged as of Dec 28). The XT5 will probably be very close to what your XTS got.

 

If you was to use Mobil 1 20,000 extended life Dexo 1 gen 3 oil you would never have an issue and you can go by your oil life monitor. I would not switch types of oil used in your vehicle. You should keep one brand after you reach over 30k miles on your vehicle. I was using different places to change my oil and my lifters failed at 79k.

 

And I use at least three / four places and do it myself using several brands of full synthetic and NEVER had lifters go with about 10 cars all over 100,000 miles, a couple pushed and went over 200,000 miles, all with something other than engine failure causing them to no longer be in my possession.

The only engine failures I ever had were in a 1970 and a 1968, due to overheating and contaminated oil, and both were rebuilt.

 

XT5 is a great vehicle, a lot more manageable around town than an Escalade for sure! They're very maneuverable, my oil life seems to be around 7,000 miles. That included a long road trip.

 

Seems like the OLM on our 2019 XT5 hits every 7,500 miles. My CT6-V hit 0% for the first time at 2,500 miles, and then it's been more like 5,000 since then.

I assume that oil was sitting there before you bought the car?

 

Yeah, it’s more in line for any vehicle 6,000 to 7,500 miles between oil changes. I know the monitor also takes time into account. But really 18 months, 8,800 three oil changes seams very excessive.

 

The OLM (no matter which brand/model of vehicle) is scary accurate in advising on remaining oil life - with a significant "safety" margin built-in. The systems use a slew of inputs and algorithms to determine what conditions the vehicle operates under. Slow, cold, short hops = low oil life. Long steady highway runs = max oil life. Some systems even use turbidity (how "dirty" does the oil look) sensors to factor in that variable.

You reset the system at oil/filter change. It then monitors stuff like ambient temp, coolant temp, power level, rpm, braking, intake airflow, fuel consumption, yada, yada, yada. All that is mixed together to calculate how fast the oil is "wearing out". I'll guess that brand new vehicles have a "break-in" factor in there, too - sort of like the rpm limiters in some vehicles for the first 500 miles. OLM has come a long way since the 80s.

Let's assume your particular vehicle was designed, built, and tested using Mobil 1 synthetic 5W-30 and a GM branded oil filter. THAT's what the system algorithm in THAT vehicle is groomed for. BUT, since all "modern" 5W-30 synthetic or blend oils are so damned close in formulation and characteristics - no matter who markets them - the system will still accurately advise on life remaining no matter what you use. Part of that is why there's a significant safety "fudge factor" built in.

"But, Sub, Slippery 70 5W-35 Magic Blend synthetic is a MUCH better oil than Mobil 1 (my friend says so) - how does the OLM know it's so good?" Your choice, your call, your money. Just as with gasolines, spark plugs, tires, oil filters, car wax - we all have opinions and no one can change them. "My mind is made up - please don't confuse me with facts!"

 

Correction, I have about 2,000 miles on my last oil change and it's at 29%! It's been 8 months...

 

Your late algorithm factors in elapsed time since OLM reset. Earlier versions said "Follow the OLM or annually, whichever occurs first."

So your combination of little driving, your particular drive types, and elapsed time is all factored in there.

 

Oil life monitor systems is an active topic of discussion on a lot of auto forums. A development paper was posted recently on the Honda Ridgeline forum which brings to light the engineering built into the Honda algorithm which is probably very similar to that used by GM. We will probably never see a similar paper written internal to GM, but can serve to reassure us dinosaurs who are convinced by what we did 50 years ago must be done to the vehicles we drive today.

Here are some key points:

• The algorithm was developed assuming the use of lower quality oils.
• The algorithm accounts for some old oil remaining in the engine during a typical oil change.
• The system uses coolant temperature, intake air temperature, intake air flow, engine speed, and vehicle speed to calculate oil life.
• The maximum degree of error between calculated and actual oil life was 15% - the displayed oil life accounts for this maximum error.

Interesting reading:

 

Doesn't make much sense to be back at the old dino oil philosophy of oil change very 3,000 miles as recommended by oil change stores. Synthetic is supposed to be good for 10,000 miles! I've been going by that philosophy since I started using synthetics. Never went that long, usually about 7,000 miles and not just Cadillacs, Audis and VWs too, recommend 10,000 miles!

Even my 2007 CTS, which had a very similar 3.6L V6 engine, recommendation was 10,000 miles! That seems like a lot to me, but 3,000 seems ridiculous!

 

What about oil filters? I would think that the most commonly sold oil filter would be the cheap old Fram oil filter which are supposedly 1 step above junk. Does the typical oil filter pack the gear to last 10,000 miles or more?

 

I'm wondering if the OP understands that mileage is not the sole input for the OLM?

 

I'm sure he does, as do most here, but the question seems to be: What other inputs are used that have him at 3 oil changes in 9,000 miles on a 1.5 year old vehicle? I use all the available pedal on my Blackwing engine and it still stays at around 7,500 miles per oil change (after the first one at 2,500 miles).

Regardless of whether someone can afford the oil changes on a $100k vehicle, or whether mileage is not the only input to the calculator, an oil change every 3,000 miles and every 6 months seems excessive. I'd be looking for answers, too.

Thing is he said 3 oil changes in 18 months, and he as now gone 8,900 miles and the OLM is at 19%. He does not state how many miles were driven in those 18 months - this is important info to have imo. If he is going about 8,900 miles every three months or so, he is doing quite well. He thinks the Escalade is having too frequent oil changes compared to his XTS ie. the oil not lasting as long in the Escalade, but this is not the case based on the numbers he provided - see my post #23 above.

 

I read his post to say his vehicle is 18 months old with 8,900 miles on the odometer.
3 oil changes in that time and mileage frame is not normal, in my opinion.

 

My car is about 18 months old, about 8,900 miles and the oil life is at 19% again.
This is the third oil change in less than 9,000 miles.

The bolded sentence is what is open to interpretation based on what he wrote in the first part of the sentence. Is it the 3rd oil change since he got the car and each has been less than 9,000 miles, or is it third oil change in 9k miles which would mean about every 3,000 miles. The OP needs to clarify this if he wants our experienced opinion on whether or not what he is having is excessive or not. But since he says "about 8,900 miles and the oil life is at 19% again" with the operative word being 'again', which I believe (taking into context of the rest of the sentence) means he has had three oil changes each being about 9K miles @ 19% each - if I am correct in this, then his oil life use is normal to good. As I said, the OP needs to let us know what the case is and he has to be specific, otherwise this thread is all about guessing what he really meant.

 

We can get beyond the guessing if the OP tells us the Date, Mileage, and OLM% at each oil change. We also lack the insight into the type of trips and climate where he lives. A lot of very short trips will cause the OLM% to count down quickly.

 

Sorry, I bought this brand new in June 2020. It is an Escalade ESV Platinum. Today it has a total of 8,900 miles.
First oil change happened at about 2,000 miles, second was about 5,700 miles, third is coming up on Jan 2nd.
I just feel three oil changes within 8,900 miles is very excessive. And because of my health, I can't even see the oil filter or even the oil, unless i use a step ladder, filter would have to try to get under the car. (haha)
I know 8,900 miles, but it's also 18 months. But still excessive. It won't break me.

I would say at the first oil change oil monitor didn't get reset or system is not functioning correctly.

 

And whatever you do, make sure it gets reset on your upcoming change. That will then clearly allow you to see the OLM is really functioning correctly.

 

Excalibur, you could be right about how long it sat at the dealer before I picked it. But exactly they had it set at 100% when i took possession. With only 4 miles on the odometer. But since then, at both the first and second change, they did reset it, because i run thru it to see just that and tire pressure. I will note the exact OLM % & mileage upon entering the dealership on Tuesday. I will comment to them also and present them with the numbers, see their reaction. Hey, who knows if they even open the hood and do the changes or just hit reset. I miss the old dealerships where you could see them performing the work thru the glass overlooking the shop. I'm glad I bought the extra 4 yr warranty. a month before, it gets traded in.
I'll give you the low down tuesday.

 

I'll give you the low down tuesday.

Along with the OLM% when taking it in for the oil change, could you make note of the reason for the oil change each of those times? We are all assuming it was because the OLM was below 20%, but if for another reason would be good to know.

Thank you for continuing this dialogue.
