While riding yesterday I attempted a creek crossing and it was deeper and faster then it looked. I had the bike swept out from under me, resulting in stalling and water intake. My buddy and I did the recovery ritual and got it running again and I was able to ride it back to the truck, which was a good thing because we were miles from nowhere. Of course the oil looks milky and needs to be flushed. My question is, I run Rotella T full synthetic. Rather than waste good oil can a just use a cheap oil to do the flushes and then go back to the synthetic?
