SA is a concern for DI engines and trying to mitigate intake valve deposits which are not a concern in the EJ engine. 78% and the highest TBN, while the SA on FE is. Sulphated Ash gives you an idea of ZDDP levels and the old X-Clean had. I haven't checked if the latest C3 specs limit zinc. Old X-clean had around 1,000 ppm's of zinc which is similar to high SAPS oils and higher than C3 Mobil 1 ESP. A good thing, IMO, with the old X-Clean is that ACEA C3 limited phosphorus levels but did not limit zinc.
So a rhetorical question.why do I always see information like this 1 day (seriously just changed the oil yesterday) after I do the "wrong" thing. The Sustina starts at 10.3 cSt at 100C and the Motul at 12.1.so that looks to be better right there, good thing I just changed the oil from Sustina at 3K to a new $80 batch of sustina. What specifically about the datasheet makes you think it will shear down to a 20wt? This is different than when I have change many other engines/changes using Mobil 1 5w30 (Non-ESP) and 0w20 which come out like water when draining out used oil after 3K miles. Just subjectively (with my calibrated mark 1 eyeball) it came out of the engine (slightly warm) about the same viscosity as it went in (for the fill from quart containers at about 60F). I am definitely interested in the EFE for multiple reasons.not the least of which is getting the best oil I can afford and get with a reasonable hassle, cost is definitely secondary.
I will post the Blackstone report on the Eneos Sustina when I get it back in a week or so. Click to expand.Just changed oil for 2nd fill (first was factory 2nd was Sustina) to a new batch of Sustina.
