4-stroke motorcycle oil in my car?

[Dobbie]

My latest oil change on my Ram in signature. Used 4 quarts of Mobil Super 10W30 & 1 quart of Mobil 1 V-Twin 20W50. I had the quart of Mobil 1 V-Twin laying around after I sold my Road King over the summer. Truck motor is purrring away like always!!!

Marine oil is usually a step up from auto oil.
MC oil is, maybe, a step up from that.
But you might consider trying 15w-40 diesel oil,
many use that in OPE machines.

Since most lawn mower and yard tractors spec conventional
car oil, with allowances for synthetics, your current
choice or the alternatives will be fine.

My 2¢

Because the friction modifiers I don't even run motorcycle oil in my motorcycle. No need as it doesn't have a wet clutch or common sump for the transmission. I certainly wouldn't use it in my car.

I might do it if/when the SJ and earlier car spec stuff runs out, since I don't have a cat, and do have flat tappets. Chances are it and/or me will be gone by then, though.
