If I had a turbo GDI, I wouldn't purchase any oil without the Dexos 1 Gen 2 cert on the label. That helps the engine prevent lspi - stay cleaner and last longer.
That's a good point. Is the A3/B4 cert guaranteeing the oil is high SAPS? I tried googling it but couldn't find anything definite. What certification indicates a low SAPS OIL?
On the LSPI, I thought any oil meeting SN-plus would help prevent that? The Pennzoil Euro 0W-40 I mentioned earlier is SN-plus rated, but it's also A3/B4. If it is a high saps oil, then maybe I won't consider it.
SOPUS is massively confusing on this oil and SN+...the page for the product family specifically states that SN+ does not apply for the 0W40 Euro.

But, SN+ is all over the PDS itself.

It seems likely that A3/B4 oils are probably OK for LSPI due to their higher ZDDP levels, as a little ZDDP goes a long way in preventing LSPI, but I am still a lot more comfortable picking d1G2 oils. If this 0W40 is actually SN+, I would have no problem using it...I used M1 10W30 HM for one OCI when I saw it was SN+, but that was also the one and only oil with which I have had any real signs of consumption.
Before d1G2 went live, I actually bought some ZDDP additive and would add a little bit when I changed the oil...yeah, I'm pretty nuts. That additive has been sitting around unused in my garage since I bought my first d1G2 oil (M1 5W30 AP).
