another oil question.....
I know..enough about oil, but...
I went oil shopping yesterday, in search of good 'ol Shell Rotella T 15W-40 that seems to be a good consensus choice on this Forum.
But when I looked at the service classifications on the bottles, I did not see the citations found in my 2004 owners' maunual, which are " API SE, SF, SG or SH/SJ with JASO MA."
What I saw were specifications beginning with a "C", and on some brands a specification like "SL"....or something like that. (Sorry...didn't write this down.) I checked several other brands and never saw any with the expected "SE, SF, SG" citation. (I did not look at any synthetic oils.)
I realize that specs that are later in the alphabet are usually better than those which are earlier--so SL is probably OK to use, since it follows SG. But the specifications using the letter C had me stumped. Are these oils for diesel use? Heavy duty use, not usable in a motorcycle? Phooey.
Any help welcomed...think I'll go nose around the API website..maybe I can answer my own question...
