MotoMaster 15W40 Diesel Oil

[Nessism]

Question for the hive on switching to Diesel oil.

I realized yesterday, that Sam's club sells Rotella 15W-40 in bulk. I'm there at least once a month anyway. If I want to switch from using 10W-40 Motorcycle JASO MA2 oil to Rotella, besides a new filter, and draining as much of the old oil as possible, is there anything else special I need to to before putting in the Rotella?

You don't have to do anything special. Just change the oil as normal. Mixing oils is no worry either.

I found this in the closet of a greasy spoon I worked in in 1979. It was in exactly this condition. Just now, I panicked when it wasn't where I first looked. It's weird, but I treasure it.

Now we're talking. The basic approach is to wince or feign a heart attack whenever cost is mentioned and when your wallet comes out look hard at it as if you are seriously reconsidering the whole idea of spending money.
You're not fooling anyone but it's expected to blend in with the other customers.

OK, I suppose I did ask for this when I asked if there was "ANYTHING else special I need to do......"

Special is a rather poorly defined term

I've been called "special" before.

Did you mean T6 15w40? I just want to make sure I'm not missing something or if that was just a typo. I usually get the full synthetic T6 15w40 when I have the extra couple bucks.

No, I run the 5W40 all year round in my truck (GMC Duramax 2500) and bikes. I live in western Canada and it never gets hot here like it does in the southern US; 5W40 is better for the cold starts in spring and fall. If I lived somewhere that actually got hot I would probably run the 15W40 in summer instead.

As to baseball caps, there's an order of 100 in for a test run right now waiting to be printed. Red caps with "Make Orwell Fiction Again" the words written alternately in red and blue letters.

Little known fact: before he said "big brother is watching," George Orwell said "Cat Diesel Power."

Not trying to incite an oil thread holy war here but is there much advantage other than saving a few bucks to using 15W40 diesel oil vs 10W-40 motorcycle oil which costs only a little bit more?

Around here I can get 1 gallon of:

Rotella T4 15W-40 for $12.47 https://www.walmart.com/ip/Shell-Rotella-T4-Triple-Protection-SAE-15W-40-Engine-Oil/181236405
Suzuki ECSTAR R5000 Mineral Motorcycle Engine Oil 10W-40 for $20.21: https://www.rockymountainatvmc.com/parts/suzuki-ecstar-r5000-mineral-motorcycle-engine-oil-p
Pro Honda GN4 4-Stroke Motor Oil for $23.25: https://www.rockymountainatvmc.com/parts/pro-honda-gn4-4-stroke-motor-oil-p

I currently am using the Honda GN4 in my GS1000 and given that it makes the transmission shift slicker than snot am apt to keep on using it.

...and, on perusing the data sheet, I find it's wet-clutch compatible!
Result!
I was buying it anyway, as I've used Mannol before, but this is unexpected. There's no JASO rating on the package, but that's entirely voluntary, and it costs blenders money to put their oil through that for a very small market, so there are many oils out there that are actually fine with wet clutches but don't have the JASO rating.

Nice one. I picked up 20l of 5/30 Mannol for the car. At that price I wasn't expecting much but it's holding up well.

Yeesh...$45/gallon is robbery. What oil do you use in your bike in Canada which is reasonably priced?

motul and suzuki motorcycle oil are both under 10CAD /litre. Castrol motorcycle oil is 7CAD /litre; discounts for case lots sometimes as well.

in my experience..none.
maybe some transmission related disadvantages, though more to do with viscosity than with " diesel oil "

the 1150 shifts much nicer with 10W-40 than with 15W or 20W a lot less clutch drag when cold as well. since then I've pretty much only used 10W40 motorcycle oil unless specified otherwise by the manufacturer. (ie Harleydavidson)
