Hey there, all. Looking for a bit of advice, and hoping to find some "tips" that may allow for me to save some money during the oil change process. I was wondering if anyone out there uses regular, synthetic automobile oil such as Mobil 1 for the motorcycle oil changes? I know that that Mobil and many other brands offer synthetic 4-stroke, motorcycle specific motor oils, but I also recognize the increase in price in those products from regular automobile synthetic oil. In addition, I've been told (and I think I understand ) that the needs of the two different machines are slightly different, what with our bikes having a wet clutch and all. I've read the manual, and am very familiar with what Yamaha recommends, but am really asking the question in hopes that I can get some "real world" experience from those that have tried this process. I'm really looking to see what's worked, and what's not worked for people over the years. I'm quite sure that some of you have done this in the past. It's your experience that I'm hoping to learn from, whether the experience was good or not. I'd really appreciate, if anyone responds, if you could let me know how long you've been using and what effect the oil has had on the performance and longevity of the engine and clutch parts. Thanks in advance for your comments and advice .
