My Motorcycles have Rotella T 15/40 in them. The backhoe, the lawnmower & pickup..
Ive bveen running Rotella for at least 15 of the 20, 000 miles on the bike,, no munched bearings,, clutch works great.
Bill happily ignores the facts about Rotella & says its just a Diesel oil,,
Well,, what engines are more hostile inside? Gas or diesel? Diesels LOAD the heck out of the bearings, as they crush the air in the cylinder to the point the diesel ignites,,think about it,,
JOG I've had diesels engines in bobcats and I used diesel oil not motorcycle oil,In motorcycles I use motorcycle oil the best I can get,No additives needed.I even use car oil in cars the best I can get,Not diesel or motorcycle oil.Its really pretty simply.
My question I keep asking myself is
"Is Bill incapable of grasping this distinction, or is he just unwilling?"
Heres the deal, Bill.. You take a harsh environment & find a product that will survive in it, then put it in a less harsh environment & it will Do Great. Rotella provides protection to Diesel En gines,, & will do so for gasoline engines, also. What makes Motorcycle OIl motorcycle oil is the fact that it Lacks all the super slicky stuff that car engines use to replace the things diesels use. Back before catalytic converters, there was no need for oil to be stripped of ZDDP & other things our valve train so desperately needs.,Now, however, in order to NOT foul them out, oils have to be made differently.,So, since diesels dont have Catalytics, they can have things in them that keep an engine happy & dont screw up a wet clutch.
Please, ohh please tell me your mind is sufficiently large & flexible to be able to wrap around these complex ideas.
So, motorcycle oils are designed to accommodate a wet clutch,,that doesnt make them superior to other oils, they simply do not have the additives that the modern car needs. Diesel oil, like Rotella, not only doesnt have those additives the wet clutch cant take, it has additives our valve train needs.
Give it UP, man, run what you want, spend all that $$$, but Im getting as good of an oil for $13.00 a gallon as you are for $13.00 per oil change,maybe better,
