Good info. I like the fact it has high moly and low calicum.

Correct. The RGT Q & A said it was part GTL (what%, who knows) and "other" synthetic base oils.

Not necessary a bad thing IMO but interesting if it were. QSUD always seems to turn in some good looking UOA's.

So QSUD VS RGT. What are the difference in the oil formulation?

Doesn't look like much difference between the two when comparing VOA's. A little more of this, a little less of that. Variation in overall cSt. Could be differences in the base stock that they use in each, but that doesn't show up in a VOA.

QSUD 5w30 VOA


You have to scroll down a bit for the Rotella Gas Truck 5w30 VOA
