in the gold GC formulation? This is for emissions, I take it. Does this equal less protection? It seems that emissions and optimal engine protection do not go hand in hand.
Really? Then why did you write in this thread about the Castrol Syntec 5W40:quote:
Both the Ca and Mg act as detergents and to a lesser degree, friction modifiers.
It is a non-issue in my opinion.
Which sounded a lot like making the Castrol Syntec 5W40 more akin to the Castrol Syntec 0W30 Green formulation with its high calcium and lower magnesium levels?quote:
This oil's additive package looks like something they dreged from the Black Lagoon of an SD rated HDEO.
They need to drop the Mag. by 1000 ppm and increase the Calcium by 1800 ppm.
Ha! What's up with that, Molakule?quote:

What MK was saying, IMO, is that you can achieve similar results using both Mg and Ca, but the new overbased Ca is a more expensive approach. It's the balance of the two that you have to reach. In his approach, he would use the more expensive Ca. Mg is rarely used anymore and it's more of a cost issue among most blenders.quote:

If you take a look at VOAs of Mobil 1, you'll note that the bulk have relatively high calcium and low magnesium - except for the SUV (Delvac 1) which has a greater ratio of magnesium.quote:
TooSlick:
Most CI-4+ or ACEA "B4" rated diesel oils will have the high Ca and low Mg, to minimize high temp carbon/varnish deposits on the crowns, the lands and in the ring grooves. ....
