To wit: Kirk, explain this then.. PYB already meets/exceeds GF-5 and API SN, although not "officially" certified. Still a conventional oil and not a blend.

$25/gal for Lucas vs $11/gal for Super Tech TC-W3 which works just as well....

I read the shell link and noted the Noack volality of almost 15%. Would you put that stuff in you Beamer at 15% volatility? Also,how robust is the oil at wear protection? My guess,not nearly as good as dexos or other group IV oils.

The dexos will have a much lower Noack Volatily than 15%.

The enhanced robustness of Dexos is categorized by improved low temperature pumpability, reduced volatility limits, tightened limits on weighted piston deposit tests and more aggressive sludge performance. These performance characteristics will require a formulation with additional detergents, dispersants and ashless oxidation inhibitors. Improvements in low temperature performance, volatility and piston deposit control will dictate a base oil mix of predominately Group III synthetic base stocks.

What standard do you want in your engine???

What oil do you already pour into your engine to date.

The NOACK volatility is on par for most major brands of CONVENTIONAL oil. PQI Test Results

I have no problem with that. If it was a GRP III or IV synthetic, then there would be a problem.

Here is a listing of "Private Label" conventionals. Private Label

SuperTech does not look too bad. Some, I would not use in my lawn mower..
