The local Wally World had gallon jugs of Mobil 1 Turbo Diesel Truck (TDT) oil for 13.00 on clearance and thats a decent price.....
**Since Rotella T6 is diesel truck oil (or at least marketed that way) could we simply use the Mobil 1 Turbo Diesel Truck (TDT) Oil in our honda clone engines also?? 
**Both do not have the EC (energy conserving) seal on them asfaik.... see the pic below.
I have read on
BOBISTHEOILGUY that the major reason not to use automotive oil in wet clutch motorcycles is that the friction modifiers in "energy conserving" oils interferes with clutch function."
as stated above the MOBIL 1 TDT oil does not have the energy conserving seal (nor does Rotella T6) and is the same weight I have been using for both my Vstrom and TBR7. Which leads me to believe it is in fact safe...
but I am asking the "collective" because maybe I am missing something.....
Thanks all , Cheers!
