hey guys, gals,

im in marfa tx and ran into a mercedes guy who told me to run pennzoil 10w-30 (sl) in my block based on zinc?

he also said it had to be black label pennzoil instead of yellow label(sm or sadomasochism, as he termed it).

the reason he said is that the (sm oil) will play havoc with the rockers....

note- the sl/sm is on the back of the bottle in a small circle.....

is this good information or horse hockey....

lyle
