QSUD or Mobil 1- What is the main difference?

[fisher83]

Decided to go with the QSUD. Seems like a good bang for my buck and it's hard to beat the price unless I want to deal with rebates, etc and it meets the specs for both vehicles. I'm no expert but from what I saw on the PDS, it looks impressive for $20.

You will be happy. It`s a good oil.

Agree 100%. Good choice!

I have QSUD in 2 cars and it does great. Civic and a Compass. I like to use a oil that does not need monthly explaining, just me I guess!

I think you sum things up pretty well right there. Your use history and your beliefs are certainly real and valid, but they don't necessarily prove anything at all. I have an old Ford truck with twice the miles of any of your vehicles, and it's done all of those miles on the cheapest Grp II or III bulk 15w40 available. All that proves is that an old Ford truck can go 200k miles on dino 15w40 and that the previous owner didn't waste money on oil.

When I saw the title of the thread, I was expecting a discussion of add packs, VOA TBNs, questions about the intended use, etc. I think the real value of a forum like BITOG lies not in arguments about which oil you prefer, but rather in arguments about data, numbers, and science.

Don't get me wrong, Tig, I won't use anything besides M1 0W-40 in my Jetta. The high TBN and good retention means I can do 12k mile OCIs and it has performed extremely well for me, and I got it for $5/qt. But that doesn't mean I couldn't get the same results from PU or GC. The truth, like a few people have mentioned above, is that the slight differences or advantages between premium oils are completely lost in most modern production engines over most people's short OCIs.

Yes imagine data other than fill holes and blot tests,

be still my heart!!

My long history using M1 oils is for my benefit only. I fully realize every one else could care less what my history is, and also since I have been at this oil change thing for 50 years there are many other very good oils as well. QS syn being one of them. You see, I never critize some other product, or others for using something differant.

I have learned from you, though, that if I used M1 as a default choice, I could run 10K drains in a healthy and not too demanding engine and expect good results.
This is useful information, and I'm not sure that we could say the same about all shelf oils labeled as synthetic.

Any motor oil that can meet the GM4718M is a high performance motor oil. Only a few name brand synthetics carry this spec, QSUD 5w30 meets that spec. Furthermore, QS purports QSUD to be formulated with shear resistant VIIs that I have observed anecdotally to be true. While I have also noticed that M1 seems to have better antioxidants and holds its TBN better. If you look solely at the data sheets, M1 and QSUD should perform viscometrically equivalent with QSUD having slightly better cold weather performance. I have used M1 for a over a decade, but now only use SOPUS products; primarily QSUD. I feel XOM is no longer king of the hill and I have a greater trust and confidence in Shell quality over XOM. Don't let the lower price of QSUD fool you into thinking it is less than M1 because it isn't. You pay a premium for brand and marketing when purchasing M1.

You said" you pay a premium for brand and marketing when purchasing M1". Can you prove that? If not, why say it?

 

[ottotheclown]

The thread might not be proven but then the reason we pay more for Mobil 1 is also not easly proven. So why we are paying more can it be proven by anybody? If possible please no info from the mfg.,

independent labs would be peachy keen.

It has been widely reported here from those that have contacted SOPUS that QS is a grp3. I have called SOPUS and they told me that of their synthetic oils. Now for M1. I have discussed this with Mobil tech(base oil that is) and as I have said many times that they told me MSS is a grp3 and M1 is a differant base oil blend of 3-4-5 and other higher quality base stocks that they would not discuss. Read their web site and you will see that M1 openly says that M1 is a better product than their MSS grp3 oil. Now for the additive pac comment I made. I don't have a clue about additive packs other than M1 claims their their oils are made up of 15 differant stocks. So there, I backed up my prove it.

In order to meet certain specifications and performance targets, the major synthetic brands use a blend of synthetic base fluids; it isn't unique to M1. This is especially true for low temperature performance; particularly, the MRV. I tend to favor brands that publish the MRV value in their PDS. M1 0w20/0w30 are the top dog grades for having a low MRV value and undoubtedly use the best base fluids, probably mostly PAO. M1 0w20 was tested and met the GM4718 spec at one time. The same can not be said about M1's other grades. I put M1 in my lawn equipment, PU or QSUD in my vehicles.

And no I won't prove it, but the data sheets are available and rest should be common knowledge.

Visom=group iii. Bulk of pao is suspect as missing from AFE, m1R4t and even the exalted 0w40. Bet dollars to donuts that low saps ESP has the pricey stock in it.
