Mobil 1 0W40 Euro VOA

Yeah that's what I was going to mention. I mean, ultimately, you could use this without any problems in turbo applications, but there are oils more suited for TGDI. This would be great in any N/A applications like a VR6 or something.
What "more suitable" oils would you be referring to? I'm thinking of turbo and gdi.
 
That's a lot of boron. You could almost say it's too much but with the ZDDP being increased as well, there's probably still good synergy there. For the price off the shelf, that's a good looking oil.
I wonder if boron helps with lspi? Maybe thats why there is a good bit in it.

Not likely. Boron is a sacrificial EP that can have some detergency benefits. It doesn't really increase nor decrease LSPI. Moly and ZDDP will reduce LSPI events at higher concentrations which is a downside to API limits on phosphorus and sulfur.

My comment was more about the synergistic effects of boron-based EP and ZDDP. Much like ZDDP is in a balancing act with detergents, it's also in balance with the EP additives. If you were to increase the boron at will without increasing ZDDP with it, you can cause a competition for surface area or a loss of synergy between the two additives that would then cause wear to increase. By increasing the ZDDP, they can increase the boron EP, and increase the detergents as well. Oil formulating is a careful balancing act. This is also why I don't advocate the use of any oil supplements whatsoever.

Yeah for sure. I have a VOA of PP Euro 5w40 in my signature. I think that would be "more suitable" (splitting hairs here as both oils in question will work just fine) since it has a comparable amount of zinc but less calcium. I'm not sure if the magnesium here is an anti-wear or just dispersant. the PP has much more than this Mobil 1.

Cool, reason I'm asking is, I'm looking for "the best" oil for a1.6T GDI engine. They call for, and the dealer will use, a bulk 5w-30 oil, but manual states a couple other weights as well. And OCI at 5K intervals. I've been hovering the thought of using either a 0/5W-40 for it. The 5k on a turbo gdi doesn't thrill me for some reason using Just a bulk syn 5W-30.
 
Euro and US version are same.
It is combination of GTL (60-70%), PAO and Ester.
Noack: 8.7%
HTHS 3.6.
TBN should be much higher than what VOA shows. But, Blackstone VOA is not that accurate.
Problem with this oil is ridiculous amount of sulfated ash at 1.34%. It is really not that good of an option for DI engines due to CBU. But, considering additive pack and base stock composition, it is good track oil for engines where oil temperature is in check.

Avoid this in DI engine. He is tracking vehicle so it is good option. It has too much sulfated ash. If you going Euro oils, go something Mid-SAPS like Pennzoil Platinum EUro L 5W30 that is available in Wal Mart.

Can a voa or uoa measure SA?

No not a standard one. Ash is measured with the sulfated ash test, ASTM D874. Note that you’re not actually testing for “sulfated ash” in the oil but the test itself uses sulfuric acid and sulfates it as part of the test. It’s an important distinction because sometimes the test can give erroneous or misleading results based upon the metallic elements in the oil.
 
I think that it is a combination of both, but it is predominately discussed in regards to turbo applications, most notably ones with low RPM boost. 1200-4500rpm.

My understanding is that this is more prevalent of an issue on v. small displacement turbo'd 4s.
