Is there a 50W for street automotive use?  I know about Valvoline Racing oils, and a VW mechanic in Spokane, Washington once recommended that to me, when I was still trying to puzzle out what to do about the low OP readings I was seeing at high ambient temps, long highway runs.  Part of that was not due to actual low pressure, however, but due to the previous owner mismatching a gauge and sending unit.  But, with the new gauge and sending unit, I would still see OP in the 10psi range, or even slightly lower, until I got the auxiliary oil cooler and began using 40W in summer.  mcneely
