[W126 Coupe] OIL VISCOSITY

[PONDERSOA at aol.com]

vance  you know what you are absolutely correct  i actually did  not take in 
to account i was in school in 1987  times have changed 
 i have always used  tha rule of thumb 3000 miles change the oil  and filter  
however  (CARS STILL HAD .....CARBERATORS !!!! THEN  !!!!! )  times have 
changed .... 
 as for 20 w 50 oil  that oil is hard as hell to pump on a  coooold phila 
morning  and this is the time when most engine wear  happens  
 i had a old chevy van with a mech. oil gauge i started it and drove a  few 
blocks and noticed there was NO reading on the gauge !!!! i stopped and  added 
oil it was like  honey in the bottle....  i had to squeeze it  out of the 
bottle (20 w 50) it was a cold night i then checked the oil and it  was full!!! 
(overfilled now) i had it towed home thinking i had a  broken oil pump or some 
other disaster   i finally got  to   fix things and  the thing was fine !!!!( 
it was warmer now) 
  that's when i remembered what i had been taught  in school 
 i would think we would be safe using the info in the owners manual as  a 
guide 
 because different cars ( turbo's, diesel, high revving , high temp  ect )all 
are designed  for different oils
 and to further illustrate your point  modern oils  have a  S.M.  grade ( 
small round semi circle logo  on the back of the   oil  container ) A.P.I.   
service S M/S/L  and this  means approved for all  gasoline applications up to the 
model year  2006  or so   i think the A.P.I  rating was  SG in  1985
 A.P.I. = American petroleum institute
