Quaker State Full Synthetic 10W-30 SL

[SShady]

I've run this oil in my 99 LS1 for close to 40,000 of its 52,000 miles.

Notable findings:
Molybdenum 20
Boron 7
Silicon 3
Sodium 1
Calcium 2392
Magnesium 16
Phosphorus 809
Zinc 941

61.4 @ 210
465 flash
It should keep things clean with all of the calcium. The flashpoint is high for an alledged group 3, no? Could this be a reason as to the oil meeting A3-98 standards as a 30 wt?

That is a pretty good flash point for a group 3 oil. Do you plan to do a UOA on this oil in your LS1? Do you have any previous UOAs on your LS1?

I don't think we have a single Quaker State UOA on here!

Anyone notice the Quaker State fully synthetic oils have a high flash point?

Here's a link to a UOA that shows QS 5W-30. Looks to me like it did pretty well compared to GC.
