I changed to rotella t-6 syn oil in my Rincon and have been realy happy
with the way shifts and no slipping from a start and drive cold. now the question????? my jugs of t-6 syn oil has the JASO-MA specs on them.
I whent to buy more today and this store has the same oil in the blue jugs
t-6 syn oil heavy duty for diesel engines but there is no JASO-MA spec on these
jugs. is there 2 kinds of this rotella t-6 syn oil??????
