.....and look for used oil analysis for Genuine Honda motorcycle oil - you will discover that the oil is very robust. Consistently turns in good numbers. Yamalube is also a decent oil. Kawasaki and Suzuki oil ? Eh, not so much.
I thought it was very interesting that the 10W40 oil with the best wear protection was a synthetic blend rather than a full synthetic.
I've always been curious if there is a standard for "synthetic blend." I mean, what would be the ratio of synthetic and non? One reads the label that simply states it is a blend of the two and one might assume that it is a 50/50 blend. One could very well be wrong. It might just be 10% synthetic and 90% non and can still be labeled as a blend.
I decided to experiment, just for grins, and am running a 50/50 mix of both Valvoline motorcycle specific synthetic and non-synthetic 10w-40. That's obviously 2 quarts of each. I've only been using it for a little over a thousand miles so far and [insert drum roll] I can't tell any difference with how the engine runs or the transmission shifts. All's good as far as I can tell. No complaints from me or the engine. If anything, I am sleeping a bit better knowing there is at least two quarts of synthetic oil mixed up in the sump...!
Why? I guess I just like to experiment, color outside the lines a little. We take our Ford Edge to the Ford dealer for oil changes and they use Motorcraft 5w-20 synthetic blend. I've always been curious about the percentages of the "blend" and if there is any real or only a perceived advantage in using a blend. I'm not noticing anything special by doing so. May or may not custom blend next time. Just sharing as an option for others who like to experiment.
I have always used oil that is says it is motorcycle specific. Except on one Goldwing (I have had 5 Goldwings) I used 5W40 T6 in my 2005 and it was the only one I had problems with at 200200 I had the motor taken out and a new ADG put in. Was it the oil I used keep in mind it was the only one I did not use oil that was specific designed for motorcycle use.? I do not know and am just mentioning it. I do not want to start anything I am just saying.
I just gave a quick read... I'm surprised how the use of ZDDPlus significantly reduces the protection provided by the oil it's added to. I knew a few people here have been touting that additive for our GoldWings. I considered it but never got around to ordering it. Glad for my procrastination now.
