Mobil Full Synthetic 5 quart jug for 19.98 @Walmart.com

[Slick3914]

Why?

I like Mobil oils. Supertech is a good product as well.

 

[Slick3914]

It's interesting that Mobil Full Synthetic 5w30 and 0w20 have the dexos cert but 5w20 does not. I wonder if it does not meet the spec or if they choose not to pay Mobil for this grade.

GM doesn’t spec 5W-20 for anything so there is no need for a Dexos cert.

Many prefer a name brand synthetic over a generic synthetic. There is nothing wrong with the oil from Warren distribution that Amazon, Costco and Walmart all put their name on, but the same probably goes for synthetic oil from Mobil, even the base version. It certainly still meets the criteria to be called a full synthetic, just with an actual name brand and Dexos certification like some other full synthetics, including SuperTech.

I just like having even more choices for a $20ish 5 quart full synthetic jug. This sale does that, and even covers two 20W and a 30W option and you don't always see that with sales.

is not Mobil 1?
Difference?

My response wasn’t to you. I was asking another member who said they would use it over Supertech. There is nothing that shows this is better or worse.

I would not “condemn” an oil for viscosity based on a Blackstone UOA.

According to BS, it did shear out of grade by "alot". In this case is it BS as the tester, or just the spectrographic test itself ?

If another spectrographic test from another tester showed similar results, then would that be grounds to back up the OPs opinion on this oil, in this engine?

I think it would.

20W and 30W

What?

 

[Method]

What?

The sale is on three different versions of the oil.....5w-30, 5w-20 and 0w-20, representing two different "hot" viscosities, 20 and 30. Hopefully I got the phrasing and numbers right, lol

I know. My reply was intended to be to the conversation in general. Agree that there probably isn't much difference between the 'base' versions among synthetics among various brands. Some people just like to have a name brand.

Yes that makes more sense.

The everyday price for Mobil FS 5w-30 at Bi Mart stores out west is $17.99.

Interesting. I wonder why it is cheap at that retailer in the Pacific Northwest. That's probably cheaper than SuperTech at Wal-mart.

It's always been cheap at their stores. I used to buy it all the time a few years ago...especially when I would travel to Oregon for work all the time and avoid WA ST sales tax. It's called a membership store, but it's only $10 for a lifetime membership. It was $15.99 for years, and would go on sale two or three times a year for even less.

All three viscosity ranges are $17.99

I'm assuming this is Mobil's version of Pennzoil Full Syn ?

It predates PFS by many years, I'd say it's been around a decade or more and was primarily designed for Mobil affiliated quickie lubes. There is a HM version as well in the same grades....

I think it would.

I think his point is the "shear" might be due to excessive fuel dilution, which thins an oil out as well, especially in a turbo charged engine. Also, short winter trips can lead to moisture and other unburned contaminates. You probably want the fuel dilution add-on when getting a UOA, making it slightly less useless in a passenger car or small truck application....

Yeah it used to be called super synthetic

 

[silversport]

they still make Mobil Super Synthetic unless that has changed very recently...

As noted, according to the UOA there was a viscosity deviation. But you cannot determine why that happened from this particular analysis, the most likely reason is fuel dilution. You cannot say for certain it was caused by mechanical shear of the VM.

Blackstone does not really measure fuel in a sample, they infer it from the flash point which is an inherently imprecise measurement. In addition to that they have shown difficulty in making a precise measurement of most anything. Their fuel estimates have been shown to be wildly inaccurate in the past.

So people make the statement that it "sheared out of grade" when there is actually zero evidence of that. It's not the spectrographic analysis, it is the viscosity and flash point measurements that are the issue.

If you prefer, W-M.com is selling the following Mobil-1 5-quart 3-packs for $68.88 (or $22.96 each) with free shipping:

- Advanced Full Synthetic 5W-20 & 10W-30
- High Mileage Full Synthetic 5W-20 & 5W-30
- Advanced Fuel Economy 0W-30

I picked up a pack of the 5W-20 for my Charger. Works well for two changes as she takes 7 quarts to refill.

Look at the bottom of the page for all grades.

I’m not even sure that the vanilla Mobil 1 these days is all that great, let alone the two more entry level Mobil synthetic offerings I really think that there are some great M1 oils but that’s in their higher tier offerings (such as EP and ESP and the Euro and Supercar stuff). I have no real concrete evidence to back up my feelings here though, it’s more of an educated hunch to be honest. But given the fact that M1s higher tier products are not really all that expensive, I think it’s worth it to go for them over their more entry level stuff anyway.

If I wanted a synthetic oil on a budget I’d grab Kirkland or Supertech over the entry level Mobil offerings any day of the week.

Why do you think "regular" Mobil 1 is not all that great?

 

[Patman]

Why do you think "regular" Mobil 1 is not all that great?

To be honest it’s more of a hunch but it’s also because in the early days of M1 they had only one version and it had the best ingredients (like the tri synthetic era where it used AN, Ester and PAO) I feel like the better M1 offerings (EP, ESP, Euro, etc) have more of “the good stuff” and vanilla M1 is built for a lower price point and may not keep engines as clean in the long run. I’m sure it’s good enough to get most engines to a very high mileage but it’s just that the higher tier versions are more likely to keep the engine in better overall shape at those higher mileage levels.

If people are finding that VRP is reducing their consumption on engines that previously ran nothing but vanilla M1, that does point to the fact that maybe it’s not so perfect at keeping the piston rings as clean as they could be.

No doubt, if the reports are factual.

I see no real advantage in M1 as opposed to any other branded oil such as Valvoline or Pennzoil or Chevron or even ST for that matter.
