2 stroke oil

[sheltbt]

I have a Yamaha 175 V6 with oil injection. I just bought this motor and was wanting to run 2 stroke synthetic oil. Would it harm the motor if I do not flush the old dino oil out and just top off the tank with synthetic?<br /><br />Thanks in advance<br />Bruce

I don't know anything about Yamahas but why are you wanting to run synthetic? Is it not performing well on standard oil? If it ain't broke I sure wouldn't try to fix it.

Re: 2 stroke oil

As your motor is specified for a certain oil quality, this is the type of oil you should use. Use well known quality, no discount qualities.<br /><br />It will not benefit from the extra strength in synthetic oil but it sure will suffer if you go below standard.<br /><br />Oil isn't just oil. But good oil is good.
