I'm not asking opinions here. I'm looking for real world experience. I'm sure some say use conventional oil for the first change. But today's engines are much different than they used to be. It's time to change my break-in oil. I plan to run synthetic at the 100 hour mark. But I'm only around 15 hours right now. So here's the question. Has anyone here used synthetic oil on that first oil change at such low hours and if so, did you see any adverse effects? I'm feeling pretty confident it will be OK but I would like to hear from those who have already done so. I have two Kawasaki 850Vs. The shop manager at my dealership said they recommend first oil change around 10 hours now but they use Kawasaki conventional oil. I'm obviously doing it myself and I already have the synthetic oil in the shop. Don't want to buy some conventional oil if I don't need to.
