Answer: Yes. The best oil additive I have used is Dura Lube. The moment you put just a cup (8 ounces) in your oil you will notice engine noise decreases, fuel mileage and power increases. I use Dura Lube in my twin-cam Harley engine on each oil change (I have also used CD2 brand). These products reduce friction and heat in the engine and you will learn to love this product due to its engine protection. Just use it in the engine oil, not the transmission and primary. If you have a bike that uses the same oil for engine, transmission and clutch, Dura Lube will be okay to use. It may be good for a Harley in the transmission and clutch, but I have not done so and I have not checked with Dura Lube to see if it is okay. I would assume some in the primary case will do no harm, but the transmission may be a bit risky. Dura Lube does sell a manual transmission additive that you could use in the transmission. It would be best to use Harley's synthetic oil in the transmission and primary chain case
