Granted Mystick will meet and exceed our mileage expectations however
the more we research oil the more we realize any major brand will meet or
exceed our mile expectations... there is not one oil in the 300,000 mileage
club... there are 30 40 50 grade oils... there are synthetic and mineral oils...
for some the deciding factor is cost.. no problem I can respect that
Im purposely reposting my post from a few posts up in this thread. Im scratching my head on your reply and not sure how or why you did reply.

Mystik JT8 Semi Syn 15w50, made by a major refiner (Citgo) and has been around forever. Mystic is Citgos brand, Citgo also formulates private brand oils.
Ive post numerous UOAs in here and someplace is also a VOA. I personally love the stuff, not because the low cost but because its the only reasonable after market oil I can find besides Harley oil (of which I believe Citgo also makes but have no solid proof) HD formulations are close though.
Anyway, here is my UOA post, it is self explanatory. Oh and the cost? Roughly $30 deilevered to my home for a TWO GALLON jug from Rural King, you can also order direct from Mystiks website. .. If you have a Rural King near you, the price for a TWO gallon jug is only $24.99 without shipping.
Here is 3 UOAs on the Mystic;

Here is the VOA; (note in Blackstones comments they incorrectly refer to it as a 15/40, Its a 15/50 as posted on the top of the page in the VOA

We are in a "motorcycle lubrication" thread.
OP was looking for a less costly 15w50 oil. I gave him that oil, hands down in the links above, Mystic a premium HDEO. It cant be beat and also very hard to find 15/50 or 20/50 HDEO in the USA at reasonable cost.
Mobile 1 15w50 automotive is another option at slightly high cost. I was tempted but it doesnt have a HDEO CH4+ or higher required by my bike maker.
It does claim a CF but makes no sense to pay more for a lower rating.
Thanks to this link from 'Fastgame" I might be tempted to try the Mobile 1 15/50 for fun as I am at the last of EIGHT gallons of Mystic that I purchased for my bike and also used it in my boat last year. All told over the years I have used about 10 gallons of Mystic JT8 in my bike and could not be more happy with an oil.
AS far as this talk of 300,000 miles, that is too bizarre for me to even approach.
)
Anyway, always been curious about other oils but wanted to stick to the Harley recommendation for HDEO, as I know my bike inside and out, noise and
most important I know my oil temperatures in every possible operating and riding condition known to mankind (except for temps below 50 because I live in the south. )
(Im sure not many in here do know what temps they run at, it was an eye opening experience for me, years ago when I installed a digital oil temperature dipstick)
From the mountains to the sea, traffic jams to interstate speeds, hours at a time at a true GPS 80 MPH two up @ 100 degree outdoor temperatures plus then beach traffic, massive storms ya. da ya da...
I have convinced myself to maybe try the Mobile 1 for fun and use my last Mystic on my boat oil change this spring maybe. Just for fun, to see if their is any difference, better or worse with oil temperature between the oils. I do not in anyway think the Mobile 1 would be any better for the engine, that would not be the purpose of trying the oil, in fact it goes against Harleys HDEO requirement but I know I will not be doing any damage.
