Anyone using Shell Rotella diesel oil in their bike? Would it be a good choice for the primary?

 

um, why?

 

SOME PEOPLE HAVE GREAT IMAGINATIONS AND I CANT IMAGINE WHY YOU WOULD WANT A DIESEL OIL IN YOUR PRIMARY. I KNOW IT MUST BE A GOOD REASON, PLEASEEEEEEEEEEEEEEEE,ENLIGHTEN ME.

 

I've run it during the winter a couple times. Too thin for my area during any other time of year. Never tried it in the primary 'cause I run mine dry. No reason it wouldn't work, though. It's an excellent oil andretains its viscosity better than most oils.

 

I've used standard 15w40 diesel oil in the engine.....however, ONLY for winter months though. When the weather gets to around 40 degrees or lower and stays that way.....I put 15w40 in. When, it warms back up.....20w50 gets dumped back in.

I used 15w40 in the primary extensively. It works really well in there. Then again, any 10w40 through 20w50 works just as good.

I've used Rotella, Motorcraft, Castrol, and even store brand diesel oils......I've seen no difference.

 

I don't see any benefit running rotella. Other than if it's free.....?

 

Sure there is a benefit.......one quart of Harley's Formula Plus is about the price of two or three quarts of Rotella 15w40 diesel oil.

The primary does not require any specialexpensive magic potion.

 

Are there any addatives in Rotella that could be considered harmful to the engine or primary. Or maybe be beneficial?

 

I use Rotella Diesel in my crank during this time of year. The weather is cooling down and I see no problems using it. The owners manual actually says diesel oil is ok. People spend too much time debating oil. Pretty muchANY oil will work ( as long as its the right grade). The key is regular oil changes. I have better oil pressure with the rotella than I do with my Valvoline 20W50 Motorcycle Oil I run in the summer, but it is most likely due to how cold it is now.

 

From what ive read the Rotella has more zinc and something else than regular oils. This helps reduce wear, but most companies have phased out the majority of zinc and the other additive due to emissions regulations. Ill see if I can find the site. It something like "bob the oil guy".com
