Here it is. Industrial Division contains the MSDS, PDS, and the Volvo PDF's.

It's really hard to beat those two for the money.
It really is. Two very good oils.
Maxlife full syn is 7%

GF-5 actually allows higher volitility, iirc.
Motorcraft looks pretty good as a value leader.

Look at the GTX, though. Another case of the GTX performing right there with full synthetics.

The Chemists were thinking with their dipsticks Jimmy!

I wouldn't put to much stock in a test that was paid for by a party that has a vested interest in it.

That's interesting. Do you know what the GF-5 NOACK limits are?

Another reduction in zinc and phos. Looks like they are gonna force older cars off the road.

Umm as far as I know, the GF-4 limits stand. Same with NOACK. http://www.gf-5.com/the_story/testing/

That started already when they declared SM rated oils.

I think it will just create a niche market for small engine lubricant companies like Amsoil. They will come out with product lines designed specifically for this market and because the cars won't be under warranty, they don't have to worry about boasting API certification.
Old cars are here to stay, and my '89 Cabriolet & Austin Mini are no exception!

I have Lucas 5W-30 in one of my Explorers. With over 5,000 miles on the oil, the level on the dipstick has not dropped. Not sure if there is a big difference with the 10W-30 but if 40% is remotely true something should have been happening.
Btw the engine is smooth, quiet and MPG is at least as good as the other synthetics I have used in this vehicle.

I skimmed over gf-5.com and found this:
“Controlling oil consumption (keeping oil in the engine) is necessary to ensure proper engine performance and oil consumption is related to oil volatility. The GF-5 standard for oil volatility remains at the GF-4 level of 15% maximum. Oils wanting the ILSAC Specification must meet this volatility requirement.
Other factors influencing oil consumption include engine age, engine design, and proper maintenance.
Oil volatility is directly related to the selection of proper base oil components and not additives.”
Is there something I’m missing?

If it's the same, it's the same. That's why I said iirc, so someone would check.

The NOACK test is done at 302 degrees (F) oil temp. If what I've read is correct, many street cars don't see 212 degrees (F) oil temp, which is considered to be normal operating temperature.
I wonder what the volatility of these same oils would look like at normal operating temp?
But if an oil is 40% volatile @ 302(F), would it still be significantly more volatile @ 212(F) than the other oils? Is that safe to assume?
Regardless 40% volatility @ 302(F) does not meet current GF-4 specs.
Also, it could be that you wouldn't notice that big of a consumption issue in normal street driving with 3-to-5k OCIs?
