It would be interesting to see a VOA posted by by the Esso XD-3, 0w30 users/fan club.

With an ash level 1.5, I'm curious to see the amounts of metallic adds & whether it contains a significant % of magnesium.
 
I checked twice recently at a local Wal-Mart and haven't seen any XD-3 on the shelf.

Would have been fun to compare what they ask for it, compare to the Esso bulk station?
 
Actually 0w30 is a lighter HDEO weight than is traditional. Mention using a SAE 30 grade in a diesel engine even 10 years ago and pretty much everyone would be laughing at you, especially for big rigs. These days, many new diesel engines are specifying SAE 30 viscosities, and XD-3 0W30 fills the need.

As is common knowledge here, the only way to achieve the 'energy conserving' rating with a true 'synthetic' oil is either to deliberately formulate on the extreme thin side of the SAE 30 viscosity (ie: the approach taken by M1), or to blend your oil in such a way so that it will experience some natural loss in viscosity.
Each approach has its advantages and disadvantages, but the former arguably causes accelerated wear, while the latter causes accelerated chemical degradation of the lubricant, both factors that do not bode well for extended drain oils. Thus pretty much every oil specified for 'extended drains' will not carry the energy conserving ratings.

As for XD-3, excellent product, it deserves to be on the top shelf right next to Amsoil, GC, Delvac-1, and probably Mobil 1 Extended Performance (once we have more data).

I think I will take a trip this Spring up to Sherbrooke Quebec where, according to the Imperial Oil Website, I should be able to find an Esso Bulk Station.

That's all I need. Even more oil stored in the garage.

WalMart has the 0w40 for $22 for a 4L jug. Esso sells it for around $15.

I havn't done a VOA, but according to my used oil analysis, XD3 has a truckload of calcium, phosperous and zinc, but no magnesium, boron, moly, etc.
 
Any 0W30 oil with and HTHS of 3.6 sounds like a winner. I think I would try!!! My personel restrictions wich I do bend for expermintation is not to go below and HTHS of 3.5 if it can be helped!

================================================

I follow a thread for upteen posts ... then whaamo... somebody uses an oil phrase I have no clue about.

If you don't mind John... what is HTHS & how did you come up with a 3.6 when applying it?
 
Triple Seven, I hope this helps!

quote:

1. The temperature for an HTHS measurement is done at 150C or 302 F, which is the average peak temperature likely to be encountered in a bearing.

2. The oil is mechanically sheared at a rate of 1 x10^6 shearing operations/second.

3. Minimum Oil Film Thickness measurements (MOFT) of operating engines did not correleate well with actual wear in service. A method was devised by which the oil temperature would be elevated to worst case and sheared to determine the optimum viscosity which better correlated with wear.

Three Exxon Researchers found that a minimum HTHS of about 2.8 mPA.s was the MINIMUM HTHS viscosity needed for normal wear, with the higher the HTHS being better for minimum wear. IN general, the higher the viscosity, the greater the HTHS.

For example, in a fleet of taxicabs using a GM 4.3L V6 engine, if the HTHS was 2.35, the startup film was 0.097um and 2.56 um at running; if the HTHS was 2.98, cP, the Startup oil film thickness was 1.231 um while the running film thickness was 3.22 um.

In Dynomometer wear tests using four GM 3.8L engines, the wear mass of a connecting rod bearing was as follows:

HTHS 2.1
mass loss (gm.) - 190

HTHS 3.2
mass loss (gm.) - 28

For "mains" bearings:


HTHS 2.1
mass loss (gm.) - 150

HTHS 3.2
mass loss (gm.) - 40

A jump in HTHS by about +1.5 results in approximately 1/5 the wear. Now this relationship is not linear and flattens as one nears a 40+ weight oil.

I should also mention that this test showed little differences in wear between a high quality 5W20 and a 10W30 for oils of close HTHS. For example, The average wear of one of the 3.8L V6's showed a total wear of the Connecting Rod bearings as 48.4 grams for the 5W20 verses 44.3 grams for the 10W30. For a 10W40 oil, the wear was 39 grams!!!

[Mola's comment: I think this test verifies my earlier comments that most daily driver engines can use any oil from a high quality 5W20 to a 15W40 fleet oil.]

Summary: It was found that HTHS correlates better with wear values found in actual oil analysis and actual tear-down measurements than does measuring the oil film thickness in situ.

I posted a VOA of XD3 0w40 some time ago, tho' under a different user name (stopped following this board for a while, then re-registered). Scroll down a bit and you will find a comparison with Delvac 1 and M1. I suspect the additive package for the 0w30 version is similar. I use 0w40 in my '93 V6 toyota pickup now. As soon as the car (2L turbo) is off warranty, I will us it in that too (XD3 doesn't carry the A3 rating called for in the manual).

Why isn't ACEA A3 listed as one of the specs? It's the only thing holding me back from trying this oil.....

They are marketed for deisels I believe. I'd run it if we had it here.
 
It says "recommended for applications requiring the following performances:" That means Esso certifies that the oil meets those specs, not the API. The bottles don't display the energy conserving starburst either, likely because this oil contains too much ZDDP. In my mind that's a good thing. The additive package in XD3 would have to be seriously downgraded to meet current specs for gasoline engines.

So the facts are:
a)XD3 is a top shelf oil, right up there with the big name brand synthetics, but Esso chose to sell it in a "plain brown wrapper" at a very reasonable price.

b) XD3 is not approved for any new car warranty even though it's probably better than any of the oils that are approved. So if your going to lay awake at night worrying about your warranty, don't use this oil.

Personally, I could care less about the first 60,000km, it's the other 500,000 that I'm concerned about. I want to give my cars the best chance at getting there without having to replace the engine or transmission. So XD3 goes in the engine right after the factory fill and Amsoil ATF and a bypass filter goes in the transmission shortly afterwards.

I'm not so sure:

Here is a quote from our Vibe's manual:

"If you are in an area of extreme cold, where the
temperature falls below −20°F (−29°C), it is recommend that you use either an SAE 5w30 synthetic oil or an SAE 0w30 oil."

I dont think this statement necessarily means that one *cant* use 0w30 all year round...just that it works very well in very low temps.

At that very least there can be no problem, warrany wise, putting in 0w30 in the fall in anticipation of winter. GM cant expect one to put in 0w30 only on those days that less than -20 F is predicted

True, but GM is expecting to see the API donut and starburst. Neither are on the label of XD-3.

But Starburst and API should/would take a backseat as the use of 0w30 is written up in this GM car's owner's manual as an acceptable engine oil....unless there are 0W-30s with API and Starburst.

Now this is good news.

That's only 15 mins from my house! I erroneously bought the President's Choice 10W30 thinking it was the rebadged XD-3 so I'll be making a stop here.

Thanks for the info.
 
BTW, I just gave these folks a call:

Smith Agency
17546 - 57 Avenue,
Surrey (Cloverdale)
604-574-7404 for sales desk

I asked for a quote of XD-3 15W40. All sizes, except the 205L drum were $2.90/L. The 205L drum was $2.70/L.

But, as Pitzel has pointed out, Canadians can get the Esso XD-3 15W40 sold under the President's Choice label for less than $2.90 - although I don't have the exact cost I think it was about $2.25/L.
