After buying a used 40 hpr. direct fuel injection Nissan I have not found anything but quicksilver for this motor (locally) the oil notice on the motor says to never fill with a mixture of this oil with any other oil or gasoline into the oil tank . I assume they are talking about regular two cycle oil and the synthetic direct injection blend .would it be ok to mix quicksilver and Nissan oil ,both being specifically for two cycle low pressure direct injection motors ?
I think you will be fine with the quicksilver. I believe you are correct in the statement that they are referring to mixing a standard "mix" type of oil with a direct injection type of oil. The last direct injection motor we had we used quicksilver in. Great oil for the price and can be found at most large box stores.
