I have heard of Schaeffer's. I have not been able to find any documentation or comparisons, but the testimonials from car and diesel users that I can find runs about 60% for/40% against using Schaeffer's products. However, the specific concern I have is, after checking their website, they do not show a motorcycle specific oil; I'm in the camp for m/c only oils in a wet clutch engine.
There are those who say that motorcycles do not need an m/c only oil; others who use m/c only oils in their bikes. I've done both. Castrol GTX 10/40 conventional car in an old CB 550 changed every 1000 miles; no clutch slip. Valvoline conventional car 10/40 in a CM250 every 1000 miles; nasty clutch chatter. In the intervening years and seven bikes later (enduros, street, cruiser, scooters), my favorite m/c oil with zero clutch problems, chatters or slipping (changed every 8,000 to 15,000 miles).
Opinions about m/c only versus car, conventional versus synthetic, one brand over another, will vary and can become quite heated at times. Find what works well for your bike, what price point is comfortable for you and stick with it.
