One of the best explanations of oil I have seen.

I've seen this on a few forums, seems to be making the rounds - pretty basic, nothing new here really. Anyone not using synthetics has had their head in the sand for the last 20 years

cool

Nice

First time I had seen this....had not seen such a clear explanation...guess I am am an ostrich since I have not been using synthetic since 1996..who knew! only jet ski firebird boi i guess

I've seen this, he has a bunch of good videos on youtube. Even if you're familiar with the concepts he's explaining, the videos are fun to watch.

ignore him LOL

I would also like to point out that the video makes a valid case for running dino oil in a track bike because track bike oil gets changed at more frequent intervals.

either way the video was very informative and concise .

I wonder why they use non-synthetic oil to break-in the engine.

Synthetics are too slippery to allow good piston ring seating against the cylinder walls during break-in. ntnoa.org has a good article about breaking in motors.

synthetic vs conventional oil

Oil cooled to -35F!!!!!!
I don't know about you but I don't ride when it is that cold
If you are going to be riding at that temp and changing your oil every 7500 miles, go synthetic.
There is a lot more to oil performance than viscosity!!
Not mentioned is the better detergent properties of standard oil vs synthetics.
Not mentioned is the tolerance of high temperatures that bikes can run, which pretty well dictate that you change your oil often no matter what type it is.
I have yet to see good evidence that the frequent oil changes most of us do with high performance bikes/track work/racing, at the temperatures I ride at, 50-100F, makes a difference in performance or longevity.
If such data exists, please share it with me. Or not. I have yet to need to rebuild a modern bike/car engine using frequent conventional oil changes. The engines don't fail, and I don't have enough time to wear them out on mileage. I ride track but don't race. Maybe that makes a difference. Whatever you do, don't buy a used bike from me I guess.

Who is "they"? Many vehicles do start with synthetic today. That is outdated thinking due to better alloys and machining. And I don't for a second believe in the "too slippery" argument.

Actually this myth has been dispelled right on Mobil 1 website - it's all in the methodology

Maybe if you're a pro team tearing down and rebuilding the engine every year, and even then, track use if even more of a reason to use the best synthetic possible

I'm not sure what the factory puts in but it's generally recommended to put in synthetic on the first oil change after complete break-in. For trackday miles, I'm told every third session which I think now is a waste because this oil is looking pretty good especially when using the best synthetics such as Motul 300V. I'm not throwing away perfectly good expensive oil so I am monitoring it. My rule now is around 500 trackday miles and may extend that.
