Reply to "Truly which synthetic brand of motor oil is the best?"

Redline uses a different ASTM method for HT/HS than Valvoline , Pennzoil and other oil makers .

Sorry , I cannot recall the differences in these methods .

Solids . All moly's are solids correct ? Even the newer oil soluable type used in most car oils ?

Redline should go on forever and no need for solid additives.
