    Exactly what don’t I understand about viscosities? Let me know so that I can straighten you out on that. Yes I am aware that the first number is how it flows cold. So unless you are starting your bike when it is as you point out 0C or so, it is too thin. And since you are apparently in South Florida, you aren’t doing that either.

    My point is that unless you are operating the engine at or near the extremes of temperature the engine will never see the viscosity equivalent printed on the bottle. The label is deceiving in that sense as the engine sees equivalent viscosity at both low and high temperature but not, for example, 50 wt at zero C or 5 wt at 120 C.

    LOL !

    do you think they specify the bearing clearances to run a different oil ?

    how about cam journal tolerances ?

    these threads allways entertain, it's hilarious marketing regurgitation every time

    Here's some entertaining "marketing" for you to interpret you ignorant fuck. Hope you find it funny.

    The typical rule that most engine builders follow is that bearing clearance establishes the viscosity of the oil to use within a given oil temperature range. Generally, the tighter the bearing clearance, the lower the viscosity the engine can use while wider clearances require thicker oil.

    buwahahahaha ... which is exactly NOT what you stated earlier.

    of course tolerances determine desired oil viscosities! but what your said earlier was market-speak crap.

    it's funny to read, even funnier to see fills get mad about it when they mix the wrong quotes !

    Nah mate, I read his first comment to be exactly what that last one expounded on.

    I know it's an oil thread and delicate egos hang in the balance, but how about some civility during discourse gents.

    I was at walmart and Mobil 1 15w50 was priced at $0.11CDN a quart, by accident on clearance, I did not check. I went back and bought every bottle and paid cash! The kid at the cash was confused that I had a total bill of $2.49 for a cart of oil...about a $1.78US including 13%tax.

    I mix it with 5w50 Quaker state that I picked up at Canadian Tire for $0.99 a bottle on clearance! Again, I bought every bottle I could find.

    Is it safe to assume that by mixing the two oils, I get 10w50?


    Yes, no friction modifiers on the label

    If you pour it in a Motul bottle, it feels the same when you pour it into your bike. That sure is a pretty bottle.

    My motor home takes 5 gallons of oil, I use Rotella T6 full synthetic at $20/gallon I'm good with that. Yes it is Type III dino base stock but it works for me. The big Cat diesel's RPM is limited to 2400. Not a high stress motor.

    My motorcycles take 1.6-2 quarts, I use Motorex 10-50 at $20 per quart I am also good with that. The big difference is PAO/ESTER base stock, resistance to breakdown and wet clutches. No dino oil in my bikes too small of a capacity and high stress engine environment.

    10w50 sounds right for an air/oil cooled bike, particularly one made where the climate is hot. Most manufacturers usually do provide a range of grades to use depending on temp. 10W40 would be fine if you live where it does not get that hot. That being said, I am a firm believer in using exactly what the manufacturer recommends during the warranty period, if you do your own changes. And keep the reciepts. Manufacturers can get antsy about about warranty claims with people that do their own work, and can deny warranty if the customer cannot prove that they used the "correct" oil. I have seen it happen.
