Red Line Transmission Oil

["Ron Fine" <RonFineEsq@earthlink.net>]

For those on the list who use Red Line oil in their transmission, a
question:  Are you using MTL or MT 90.  I live in Southern California.  I
will only be driving the BN7 in the usual warm sunny weather we have here
(if it ever stops raining).  MTL is listed as being like 5W30 SAE Grade
engine oil.  MT 90 is listed as 15W40 SAE Grade engine oil.  I think I
should use the MT 90.  Is that correct?
