OK, so this isn't a regular oil thread. Don't worry. I goofed and just wanted assurance all will be well. OK, so I have always used Mobil 1, but on this 2008, I am going economical. So, last change I used Rotella T6... loved it. Bike shifts smoother than anything I can remember. So decided to go again. Got a quart of it and then searched Walmart for a gallon.. which was hard to find.. only a few left.. grabbed one. Today, I get to changing oil. Drained, add a K&N, then start pouring the T6. About a quart in, I see it is 15w40 T6. NEVER even knew they made this.. only had seen 5w40. Well, I got no car, and I gotta get oil in there. So, I add a quart of T6 5w40 and then top off with the 15w40 T6. So, it's kinda CLOSE to a 10w40, right? I am in FL and in a month taking the bike to New Mexico and back so will be changing it again after that trip. Wanted to make sure I'm ok.. I believe I am but want a calm hand of assurance on my shoulder. Tell me I'm right! Please
