KC, I fixed your reply for you.

Blue you spend too much time on the filter forum to believe that, I think I'm gonna have to get you now!

Presumably the AFE and EP offerings get you an upgrade in basestocks.


It used to be that way but now all M1 is visom based.

We don't know that. Mobil is still the world's largest producer of PAO as far as I'm aware. I believe they are supplanting some of it with VISOM, which is less expensive to manufacture, but I doubt they've removed it from their products entirely.

Here is a little tidbit about the matter if you haven't seen it.

I guess you can infer what you want from that.

Not that i care even if they admit to containing only group 3 oils, just thought i would share that.

My Jeep came to me neglected, the top end still looks disgusting however the last couple OCI's (after 35k of diligent changes and some MMO) my oil capacity seems to have gone up. So there may have been some more significant cleaning in the bottom where I can't easily see.

This is Mobil 1 0w40 alone with never any additives cleaning up the engine from a little neglect (neglected not by me).
Notice the dirty piston, the whole engine even under the covers looked like this. The other pistons are almost totally clean (like the lower right), the dirty one is obstructed by the pick up tube.

The rest of the engine is now shiny metal, compression is OEM spec (less than 100K), it was lower up to 2 years ago.

The oil still come out with a red tint but the first few changes looked like dirty MMO and there was no MMO in the oil. you can still see the red tint on the drops of oil, thats dissolved varnish.

Like i said zero oil additives. I know that for a fact because i own it. Running PU in another one, a Honda with the same results.
Thats all the "proof i have but the picture speaks for itself.

Nice Trav! It even cleaned the bluing off the bolts!
which version were you using? SM or SN?

Oh, a "little tidbit", such juicy wording!

To quote your link:

Quote:
Just like other companies, we do not discuss our product formulations for obvious proprietary reasons. Mobil 1™ Extended Performance is formulated using a combination of high performance fluids including PAO, along with a proprietary system of performance additives.


Which completely supports what I just said and comically makes no mention of VISOM, which is discussed in a more recent presentation about their 0w-40 and how they would be supplementing that product, and others with it.

But hey, the facts shouldn't get in the way of letting us make broad-brush statements like "now all M1 is visom based", right?

Now hey, I know what you are thinking. What is that guy doing raining all over my parade! And I get that. I know how much fun it is to make sweeping gross generalizations and some guy stepping in there and saying "whoa there, there's a lot more to it than that" and letting the wind out of your sails.

But you see, the problem is that oils are formulations, not static blends of a set type of base and add-pack standardized across an entire product line. So while Mobil 1 Extended Performance 5w30 (the product referenced in the tidbit link) may contain a great deal of Group III, that in no way means that the 0w-20, 0w-30, 5w-50, 0w-40.....etc do. Now we DO in fact know that the 0w-40, recently, for the SN reformulation, has had some of its PAO swapped out with VISOM. Enough of it that the oil is no longer classified as "full synthetic" in Germany, but that doesn't mean there is none in it, just less than 50%.

Interesting Trav, I was always curious why the oil would come out of the G6 with a red tinge. Have not noticed it for a while but I'm pretty sure it was after I started using synthetic.

Get ready (

), you're failure to post a before pic means you must be trying to deceive us!

There wont be another picture later either.

Taking the pan off this car is a PITA.
This picture is like a before and after in itself. The one piston is blocked by the tube and receives less splash than the others.
The ones that do like the one in the lower right get more and are almost down to the metal clean.

This was/is SN Mobil 1 0w40

I don't take engines apart for before and after shots, i do this for a living (well okay not so much anymore) and don't take engines apart for fun. 30 years ago i may have.
If its tight and running well its staying together, this one had a rotten pan that was getting too close for comfort.

Thanks for the photo.

There is no real debate that synthetics typically have greater cleaning abilities and Mobil 1 warns about this on the label of their high mileage oils when used after years of conventional oil and require shorter OCI's for 2-3 times.

In the old 429 Ford engine in a two ton truck that had not had an oil change in years for sure the Rotella T6 5w-40 was as black as used oil drained from a diesel engine within 200 miles. Now four years later (about 1000 road miles but used on the farm moving dirt) the same oil is staying much clearer (can see marks on dip stick) but we are on the third filter change topping off after each filter change. It has the oil filter right behind the radiator so it is a quick and simple job to change out when the engine is cold. The other day we did top it off with Rotella 15w40 that I found in a gallon jug that was opened 20 years ago thinking we may change it this summer.

Interesting Trav, thanks for posting. Generally on here we get a lot of engine pics of clean engines from syns that have had it a long time and were never dirty.

I am running a Full Synthetic in my dirty Jeep right now for the first time ever, GC 0w30, I did notice it started to darken on the stick within a couple hundred miles so maybe I'll actually see an oil clean.

My oil capacity has gone up about a quarter quart lately though so even the Pennzoil Conventional and synthetic blends I've been running may have removed some grundge in the bottom where I can't see.

Thanks for the pics trav.
Add another notch for Mobil 1 0w-40. Truly a world class oil at a bargain basement price in America.

If Canada could get close I'd run it exclusively,heck if it could be had for 30 a jug id use nothing but,in everything.
