Bob Donahue, the reason against recom. 20w50 in the GM engines is for
fuel economy reasons......that nasty 20w50 ROBS all that power  from
your engine .....10w30 is recom. for my '95" Chevy Corolla"(Geo Prizm
Lsi) with the big block 1800cc. Toyota engine  ........a little thin for my
tastes and climate but 35 mpg. on the hi-way.
