SAME OIL AS USA......even states it is API CERTIFIED {AMERICAN PETROLIUM INSTITUTE} and the formulation from 2005 {SUPERSYN} is CURRENT!!!! All of the different versions can be called "synthetic" in the USA due to the court ruling outcome from a lawsuit......USA is the only country where a group III hydrocracked oil can be called "synthetic"......why Mobil doesnt need to label their bottles revealing true content here like they must everywhere else! Stick with the 0w-40 if you want a "true synthetic group 4 PAO based" oil from Mobil.

German Castrol is great if you can find it, all the other "synthetic" Castrol oils on the shelf are just like the Mobil.....mix of group 4 PAO and group 3 processed fake synthetic.

I gave up on Mobil and switched to Redline oil 125,000 miles ago when they stopped marketing true 100% synthetic oils {the Tri-synthetic was their last true synthetic} except for the current 0w-40 formula.

The only 100% synthetic Mobil 1 oil is the 0w-40.

Both are true synthetics which are available at Autozone. There are other oils that are better but you usually have to order them and they cost a lot more.

That is what I use and recommend.

I have never found the German Castrol here in San Jose ...

Valvoline Hold its Ground and Turns up the Heat

As reported in the July 24, 2008 issue of Jobbers World Online News, Valvoline launched a national advertising campaign that takes on competitor Mobil 1. The centerpiece of the campaign claim Valvoline SynPower has "four times better wear protection than Mobil 1."
According to Valvoline, the claim is based on the industry standard Sequence IVA test. The Sequence IVA is the industry standard test for determining wear performance of an engine oil and is required to meet the API SL and SM requirements. Multiple tests showed that Valvoline SynPower provided four times better wear protection than Mobil 1, as measured in these tests of 5W-30 grades.

ExxonMobil responded to the claim by saying it was "not aware of any accurate technical data to support the claim" and they requested Valvoline provide the "substantiating data to support this claim immediately."

Rather than backing down, Valvoline is holding its ground, and turns up the heat.

Marketers say the received a letter from Valvoline providing additional information and data to support Valvoline SynPower's significant performance advantage versus Mobil 1. In addition, marketers say the letter turns the table on ExxonMobil's challenge and Valvoline is now challenging ExxonMobil's claim for its Mobil 1 5W-30.

According to the letter, Valvoline says the company conducted a number of tests and commissioned an independent laboratory to evaluate the performance of SynPower and Mobil 1 in the Sequence IVA wear test. Marketers were told the tests were run on a 5W-30 since it's the top selling grade.

Now for the interesting part...

According to a letter Valvoline marketers received, the result from Valvoline's testing indicate:

Valvoline SynPower's 5W-30 wear performance is at least four times better than Mobil 1 5W-30
Mobil 1 5W-30 does not meet minimum API SM or ILSAC GF-4 specification because of its inferior performance in the Sequence IVA wear test

The letter reportedly goes on to say that Valvoline notified ExxonMobil of the failed test results in September and that the company take appropriate action regarding their claim that Mobil 1 meets ILSAC GF-4 and API SM specifications, or provide substantiation that they in fact meet these specifications.

As of today, Valvoline told JobbersWorld, ExxonMobil has been silent.

Castrol Price Decrease - Clarification

Earlier in the week, JobbersWorld reported that Castrol advised its marketers about a retroactive decrease on posted prices of $0.44 a gallon on conventional lubricants and $0.45 a gallon on synthetics. This decrease applies only to product purchased in bulk, tote, drum, and kegs. A price decrease of $0.44 a gallon will reportedly go into effect on January 5, 2009.
As a point of clarification, It should be noted that this decrease does not apply to Castrol Industrial lubricants.

But the valve cover gaskets were an issue so I started filling conventional oil 10W-40. And Valvoline has always been the best choice for that.

Above 32*F you wont notice any difference with the 0w, below freezing it will flow easier. Mobil 1 0w-40 is one of the very best oils currently on the market quality wise, vastly superior to every other M1 version and an excellent weight to use in a q45, especially higher mileage ones.

All M1 weights run on the low side of their respective weights, the 0w-40 is thin for a 40 weight, almost equivelant to a thick 30 weight in reality- their 5w-30 & 10w-30 also run on the thin side of the 30 weight scale,almost like a thick 20w.

HIGH Mileage oil usually run towards thicher limits to work as claimed.

The usual problem is the average vs peak oil temperatures. Measuring sump temperature is a long way from bearings or piston bottom peak temperature.
