Mobil 5000 and Castrol GTX are the only two conventional oil I would consider using next to my Havoline I'm using now. But, does anyone know if the Mobil 5000 add pack is up there with Havolines? The search function sucks,and can't find any info. A friend of mine told me it has been heavily discussed here in the past, so sorry for beatinga dead horse again, if this is the case.
Is Mobil 5000 considered a sleeper oil?

Havoline
Castrol GTX
Pennzoil
Motorcraft (roughly same price)
These are my top dino choices. I look for sales on these brands & stock up. Mobil is being accused of lessening their group numbers in their synthetic oils. There's a chance those accusations could move into their dinos someday too. I won't buy anymore Mobil until these accusations move into the facts stage. Then it depends on the guilty or innocent verdict.

You can assure yourself that the quality of conventional oil is excellent if you pursue ILSAC GL4/API SM grade, so the accusations for Exxon for lowering the oil group esp. with such qualifications is in these high quality conventional oil is impossible.

Not Impossible!
What's to stop them from using a lower group # in the mix????
BTW... there are different quality levels of SL/SM & GF-3/4. That why we see Coastal Oil on the left - Havoline, Pennzoil & Castrol next to it... all with the same SM/GF-4.
I know which 3 out of 4 I'm buying.

I'm not really a fan of the Mobil 5000 product line due to the sodium anti-wear additive that shows up in used oil analysis.
Mobil has a rather large commercial lubricants business & I'm sure the Mobil 5000 formulation is providing adequate GF-4/SM levels of service.
Not using Mobil 5000 because Mobil could be substituting Grp I base oils enters into the twilight zone of paranoid/conspiracy type theories.
How can a 5W-20 or 5w30 formulation pass the high temp requirements of the GF-4 tests with Grp I in the mix?

The original speculation over this oil was that it may have had a Group III base.
This matter was first discussed by Carpy, a member claiming industry credentials. Carpy was thereafter chased out of here by some of the resident cheerleaders.
Interesting how history repeats itself around here.

The single best used oil analysis I have ever seen was a 5200 mi run on Quaker State 5W-20.

Let me guess without looking.
Either the Toyota V8 - I think it;s a 4.7 (or) the Honda 2.4 four-banger. Both of these engines are supposedly the best in their class for anti-wear. Does anyone know which V6 would fall into this group?.
True, However its still very impressive that you cant tell a used oil analysis and VOA apart after 5200 mi.
You it is not a sleeper! It is what it is a low cost conventional oil from ExxonMobil, Superflow is the same stuff as Mobil 5000. I would say that Mobil 7500 is almost a sleeper since it is GIII+PAO. Nothing special about the additive package though it is the same type of chemistry that Mobil 5000 uses I belive. Havoline and CHevron Supreme are the only 5W30's that are OTC with lots of moly in them and about the same amount of everything else as the rest of the pack. Delo 400 +4 is the only 15W40 I am aware of with lots of moly in it. Everybody knows these oil work well in most applications so they too would not be sleepers. Now when we first started useing CHevron on this site some years ago it was big news since it was all GII+ and was only $1.08 a quart at Walmart and was turning in crazy low wear numbers compared to it's competition back then it was a sleeper but not now!
Triple Se7en, Not sure but from what I have see the new Toyota V6's starting with the 4.0L like the one used in the 4Runner and now the 3.5V6 are all looking alot like the Toyota V8's. Toyota's newer I4's are also turning in some impressive numbers.
I used Mobil 5000 as the 1st oil change during the "break in" of my new Sierra Denali pickup before going to my usual Mobil 1 oil. You can see the UOA posted on the site. I was not impressed, of course the engine was new so you have to take that into consideration.I just changed the Mobil 1 out of it yesterday and will be sending the sample to Blackstone to see how they compare. I agree with Blue99 about the sodium additive, I dislike that too.
Even though they're supposed to achive the same end result, you can see these add packs are designed differently.
Sometimes the GTX formula is excellent but their package changes from time to time due to availability of additives.
Havoline is excellent and its consistant.
Clean 5000 package is a unique design, it performs well and it's consistant. If your car's coolant bottle always stays full you don't have to worry about the sodium in the oil. But if your model has a history for internal coolant leaking, stay with the Havoline.
