Mobil1 High Mileage NOT ILSAC GF-5 compliant

I like niches. Instead of ALL the companies making the same oils. Like this, I was on the eBay and someone took plenty of pictures at different angles. At different distances but none of the back of the item. All I wanted was one of the front and one of the back.

Instead of a hundred of the same thing, why not have one or two here and there that can have a benefit when needed?

Im not sure if this is consistent across the board, but seems to me synthetic HM oils do not have the starburst n the front of the bottle. Whereas, Ive noticed semi or conventional HM oils seem to.

Maxlife Synthetic has the starburst.

Nothing. It passed just fine the thing is in my part of Texas most places only use the tailpipe scanner when the car is really old and highly likely to fail an emissions test. With the newer cars as long as the MIL/CEL isn't on they skip over exhaust and check other safety features (brakes, tire life etc). I guess I could have it analyzed but I would suspect that if it was seeping through the rings and frying up, the catalyst wouldn't be too happy about it. As I mentioned before absolutely zero smoke from tailpipe.

I can second this, have it in a '98 Grand Marquis that was using a qt in approx 2500mi(prior was using M1 or M1 EP), now at almost 4k mi has used 2/3 qt...

Do you use the 10w-30 for your GM?

At least a couple of things:

(1) It has too much ZDDP -- over the ILSAC limit of 800 ppm phosphorus to protect the catalyst. Is it a concern? Probably not but there is a chance that your catalyst life could be reduced.

(2) It has too much seal swellers, exceeding the ILSAC limit, which could harm your seals. Do you have to worry? Since you want to use HM oil, chances are that your seals are already bad and are trying to improve them; so, it probably won't make bad seals any worse.

I have never used HM oil even though I have 261,100 miles on my engine and never intend to do so. Replaced the valve-stem oil seals recently.

MaxLife Full Syn 5w-30

SN
GF-5
dexos1

How can you beat that ???

 

[Carbon12]

This oil has worked fine in my Cruze 1.4T. Switched over from QSUD this spring.

One thing that concerns me is that in the VOA posted by PQIA shows 982 ppm phosphorous but it's usually not that high in most UOAs that I've seen. Is the ZDDP used in some oils volatile?

So Mobil is saying thicker oil does in fact protect better and holds up better to high temps?

While I agree with the premise quoted, there's an important part of Mobil's statement that went missing

As the high mileage engines will have a little bit of bearing and piston wear, their characteristics change.

Bearings hat are opened up slightly will have greater radial clearance, which reduces the intensity of the pressure rise on the loaded face, and reduces MOFT.

They will have greater eccentricity, and greater side leakage ... and thus slightly lower oil pressure (which is what the OEM minimum oil pressure is there for, a diagnostic, not a lubricant selector.

A higher HTHS brings the oil film thickness back, reduces side leakage some, which reduces oil flow requirement from the bearing, and brings oil pressure back up. (oil pressure is an artifact of bearing draw, not a performance measure in it's own right)

Definitely don't want that happening. I've decided against using HM oils anyway.

Seals aren't bad as I have no external leaks whatsoever I'm just gonna start trying different oils to see if it's the oil that my engine doesn't like. All I've ever used in it is what's in my sig. I've heard good things about Mobil in regards to consumption.

I see that you have oil consumption. I recommend switching to M1 0W-40 SN. Higher viscosity along with 9% NOACK will reduce your oil consumption by a factor of about two or three. It's not overly thick; so, it's OK.

I know for a fact that NOACK is not the issue in my engine as Pennzoil Ultra Platinum 10w-30's volatility rate is 5.7%. I read on a scion forum (may have been scionlife) someone stated to use a PAO with a NOACK of 8% or less and consumption will go down considerably. The oil I use definitely beats the 8 percentage mark but it isn't a PAO. I wanted to try a PAO and I am seriously starting to consider using that there 0w-40 Mobil1 you're recommending. I know it's NOACK is 9% but I've also come to realize that NOACK isn't an oils end all be all when it comes to an engine sipping it up. I found it for the same price as amazon at my local Walmart so I'll be hitting it up sometime next week.

 

[Gokhan]

It's really not a NOACK or PAO issue. It's a viscosity issue. When viscosity goes up, oil consumption goes down. Before I changed the valve-stem oil seals, I burned 1 qt per 1000 miles with conventional Mobil Delvac 1300 Super 15W-40 and 2.5 qt with PP 5W-30 (non-GTL SN formula). Now, its less than 0.1 qt even with TGMO 0W-20 SN.

Get the six-pack on Amazon for $27.99 and then use the $12 online Mobil 1 rebate. If you have Discover card, it's an additional 5% off.

My local Autozone has the 5qt jug plus a M1 filter for $36 which may not be as cheap as amazon but cheaper than my current oil change setup so I'm happy. The Amazon deal only applies to Prime members which I am not and honestly have no interest in as I don't purchase enough from them. I'll definitely be picking that oil up though.

I wonder if it's due to too short OCI.

Either way I'd be trying a different oil.

Well I try to stick with 4.5k-5k because in the part of Texas I live in it doesn't take much wind to pick up quite the amount of dirt in the air. It's a desert climate so it's [censored] near always hot. I drive about 100 miles a day (roughly) and those aren't highway miles either. My vehicle is used for pizza delivery and I LOVE driving spiritedly

so I'm inclined (at least a little bit) to say that my vehicle lands under the "severe service" category.

This is not true at all. HM oils can be used in new or older engines and the seal conditioners can prevent seals from becoming hard/brittle in the first place.

I say Walmart all the way! Best prices in town

(at least where I live anyway).

Well, too much of a good thing could be a bad thing. That's exactly why API SN, along with ACEA, API CJ-4, OEM specs, etc., all have both lower and upper limits on volume, hardness, and tensile-strength changes. However, it turns out that API SN without Resource Conserving (without ILSAC GF-5) also has the same limits. API SM has no limits. Here are the Limits for API SN:
