M1 5w40 T&SUV seems to be missing all the other sub titles like SuperSyn, SuperSyn Advanced, Extended Performance... etc. Is 5w40 an older formula than SuperSyn (TriSyn before that) or is it just different?
I use M1 5w40 in both my Volvos but I was just curious.
 
M1 SUV is about the same as Delvac 1. It's a VERY good oil. One of the best.
 
The reason it's not marked SuperSyn is that it's not.

The additive package is, as buster said, that of Delvac 1. Because that is used in over-the-road diesels and mixed fleets, there some advantages to using a slightly different set of additives.

If you look at the Used Oil Analyses on the board you'll see in comparison with the other Mobil 1 formulas more magnesium, one of the artifacts of this additive package.

This oil can really take a beating.

Just did a 25,000 OCI in a VW Jetta TDI. (turbo Diesel) Have been running it since the OEM change out at 5,000 miles. It has 67,000 miles. This is a very robust oil.
 
Without being redundant.....@ $20.17/5 qts at Wally World...the best syn value out there today. Trucking companies find an oil that works(for long periods) and stick with it.

All the Mobil 1 motor oils are primarily PAO.

ExxonMobil does make ester base oils for turbines (and one PAO base turbine oil for ex-Soviet aircraft).

Supersyn is ExxonMobil's trademark for its proprietary additive and blend stock.

Seamless mix, BIG CAVEAT: within required specifications!!!

I have been using Mobil 5w30 for a few miles. (743,000) While I would not have any qualms whatsoever in back filling with 5w40, the real question is why thicken the viscosity? Given how good it is; my thought, why mix?

The other connumdrum is there are VERY few applications that directly call for 5w40. Sure it is wonderful in 5w30 applications such as my FJ80 Toyota Landcruiser's applications. Frankly, I haven't mixed it for I suspect there will be a loss in fuel mileage. On the TLC's I do 15,000 miles OCI's, this can equate to more normal 1 year change up to 3 years.

Having said that, I just am absolutely satisfied with this oil in the turbo diesel application. The mpg is absolutely wonderful (44-62 mpg) and it gives new meaning to the definition of extended oil changes. (25,000 mile OCI) :)My goal is to run this puppy a min of 500,000 miles and hopefully 1M and beyond. 25,000 mile OCI=10/11 mo.

I also have to agree with MickeyM, at 20.17 or app 4 dollars a quart it is: 1. quite the value in a synthetic product 2. a lot cheaper than when only Delvac One 5w40 was available (at discount @19.66 per gal or 4.92 per quart.

Maybe Exxon/Mobil just wants to market it as an "easy choice" synthetic oil.

Joe Avg. decides he wants to use synthetic in his pickup, so he goes down to the local WM & BAM!, right there on the end of the oil aisle is a synthetic Truck & SUV oil. It's made by Mobil 1....Joe recognizes the name & he's heard good things about M1 from his buddies. So, naturally Joe Avg. buys the M1 T&SUV oil.

A lot of folks just want to USE oil, they don't really want to KNOW oil the way BITOGers do.
 
On a practical level, I would agree with that. Back in 2003 when the VW Jetta was new, I literally had to hunt down Delvac One 5w40. All the normal places you would go for auto products either NADA or didn't even hear of it. Truck stop places heard of it, but didn't carry it.

So I finally found a jobber, got it wholesale, but had to buy one 4 gal case (didn't break cases) (100,000 miles of oil changes for me.)

Right around the time M1 5W-40, I hate calling it T&SUV, came out, I went to Kragen and took six quarts to the counter. The Kragen counter monkey wanted to know in which car this oil would go. I told him it was for my Audi sedan. He thought that was hilarious. I laughed with him, but while he was laughing at that chump who was "puddin' truck oil" in his sports sedan, I was laughing at Mobil's marketing department and what they thought of the average customer. What's next? Maybe "Green car oil"? "Especially formulated for regular or metallic green vehicles."
 
No mori, that would be Quaker State's "Green Car Blend." Those guys have a blend for everything!

BTW, some of the experts on here have stated that Delvac 1/M1 5W-40 contains about 20%-25% ester base.

Yes, there appears to be a fair marketing challenge here. It is also weird to me, in that in my estimation; this is probably one of Mobil's BEST OILS! Typically Delvac One 5w40 aka M1 T&S has had more application to BIG RIG trucks. However for the quantity they have to use it can be exorbitantly expensive to run. It also applies to more niche markets: such as, "diesel light trucks" It does have widespread application in diesel cars world wide, however, there are not many diesel cars brands and models in the USA. Right now diesel passenger vehicles of ALL types are app 2.3-2.9% of the total fleet of 230M passenger vehicles. The majority of diesel passenger vehicles are probably American diesel light trucks. This might be a defacto definition of a "minority position". So I think it also is marketed at the 12% of registered SUV's and quite possibly the work truck vehicle segment, i.e., pick up trucks: diesel and gasser etc,. But truly, it does conform to a wide range of application specifications.

I use M1 5W-40 T&S in all my cars, including my '05 Audi S4 avant. It's great stuff, and Wal-Mart has it in 5 quart jugs for $20.83 ... the S4 sucks down _three gallons_ of this elixer every oil change.

Later this year I'll have UOA results showing the oil at 10, 15, 20, and 25k with this oil changed out at 5k intervals.

For comparison testing, I'm going to run Shell synthetic rotella T 5W-40 @ 20k miles.

Should produce some interesting #'s !!

lol. Yeah. semi-dry sump design, with everything except the alternator driven off a rear facing gear reduction PTO transmission which shares that oil. Crazy stuff.

The alternator wasn't enough to be left "normal" driven by a belt-- it's water cooled.

The worst part about these oil changes is that the drain plug is about 1.25" in diameter. It is a 10mm hex key. So you break this huge drain plug free... and take it off.. and suddenly you have a fire hydrant with 3 gallons of hot oil coming out. As I discovered-- much faster than my drain pan can drain. It's the big black flat pancake looking drain pan with a /smaller than 1.25"/ hole in the funnel center.

I think it was 6 or 7 quarts that ended up on the ground. I was really unhappy. It was a huuge mess. The drain plug fell and I couldn't fish it out fast enough.

Now I just drain the oil from up top through the dipstick hole. The oil filter is accessed from above the engine, so there's no reason to get underneith except for inspection or to make sure there's no particulates building up in the sump.

Well, shoot my fellow poster, If I had known I'd have lent you my Mity VAC evacuator. I also change oil through the dipstick. Matter of fact have never undone the drain plug yet in 67,000 miles. Do you also have the cartridge type oil filter?
