Mobil 1 15-50 car oil

So much todo in many forums, has anyone actually found a difference between the Mobil 1 for bike and cars.
I hear so much and am running the car stuff in my 06 Bonneville, so far only about 200 miles. A friend has used this oil in his Bonneville for 7000 miles.
I know about the "energy saving" additive arguments and have also seen this is not applicable to high viscosity oils.
I know alot has been said and I now use Rotella 15-40 but would like to go synthetic.
Sorry if this has been covered but I want recent updates and perhaps experiences.

Love my KLR

All I can put forth as experience is that ever since I bought my first four stroke bike in 1971 I've been using motor oil in them. When I discovered Castrol GTX I was driving four cylinder air cooled superbikes and riding coast to coast in the lower 48. I started using 20W50 to combat the high temps I would encounter every season.

I never had any catastrophic engine break down over 180K of touring the continent. I live in AK. now and use Castrol 5W30 because it never gets hot here and cold starts are the norm. I believe forum members are worrying way too much about splitting hairs when it comes to some such subjects as oil types.

I concur with many other members in that if you are changing your oil at reasonable intervals and using a viscosity proper for your ambient weather conditions then any oil is good oil.

After having my head bearings (steering) go out at 10K I'm a little more concerned with making sure things like wheel bearings, swing arm bearings and etc. are properly lubed & torqued than I am about researching chemical properties of motor oils. The next serious consideration I give to oil will be whether or not to install a Scott auto oilier for my drive chain.

Vitesse: I recently saw some synthetic Rotella at WallyWorld. It had no "energy conserving" additives listed so it could represent the best of both worlds. It also sold for less than Mobil 1

There are additives in Auto Mobil1 and “Energy Conserving” oil that can cause problems with a wet clutch. I have only seen “Energy Conserving” xW-30W oil.
