My wordsmithing isn't always the best but unless noted, i try an be positive and maybe a little funny. That being said, I did something similar to the OP but not on purpose but because I'm an idiot sometimes and read to many oil thread posts on the internet. At my last oil change, I accidentally put to much Yamalube in the crankcase. I started with that last bottle from the previous oil change that has that little bit left in. Dumped it in and then proceeded to put 4 full quarts in. Ooops. Lost track. Never started the engine. So I asked my daughter to keep an eye on the sight glass while I held the loose drain plug up against the hole and ler some oil drain out. Well, this being my first bike with a sump, the oil in the glass did not lower. Im thinking to myself, 'there is a lot coming out?' Anyway, I stopped doing what i was doing, tightened the drain plug and started the engine. Oil light goes off, then back on. Immediately turn off engine, let sit for a minute or 2 and check glass. No oil. Oil needs to be circulated before the glass is useful. Ah Ha moment. Figured i was a quart low and needed to add oil. No more Yamalube and i wanted to ride early the next morning. Its 8pm and motorcycle shops are closed but auto parts stores are open. Get the only stuff they had on the shelf, Mobil 1 synthetic except the weights were different, by a factor of 5 on each end. 'What difference can that make with one quart?' I ask myself. 'Mixing different brands. What difference does that make? I ask myself again. Go home, dump it in, but i didnt start the bike. Check the internet. Call a friend. Contemplate some more in my head. Paranoia sets in. Nooooo!!!!. I did the right thing? Dumped all the oil. Slept. Waited until motorcycle shop opens and buy the Yamalube. Fill with the right amount and off i go. Did i overthink it? Will one quart of a different brands sythetic with different wieghts really make a difference? Ill never know but I waited and now have piece of mind that did the right thing. At least for me. So, Im sorry to bore everyone to death if you actually read this and i wanted to explain my feeling better or not, when i go through oil change threads. Enjoy the road everyone.
