Exactly what I was looking for. I have a 2007 Yamaha YZF250 and I believe this is the oil I have been searching for a long time. Smooth operation and easy starting even when cold. The clutch is smooth and functional, and it doesn't change after 10 hours. The gears shift nicely. I am satisfied with Amsoil, both for my forks with the Therapy and for my two-stroke agricultural equipment with the Saber. The only downside is that I am from Nisyros and there is no one to bring them here, so I have to order them with an additional 5 euros for shipping. Hopefully, the company can find more distributors because it is truly a very good company and it's a shame that people don't know about it.

I changed the oil in my four-stroke Kymco scooter and used the AMS FORMULA 4-STROKE SYNTHETIC SCOOTER OIL. Before, I had Motul synthetic 10w-40, and I noticed a huge difference. The engine runs smoother, especially the idle in the morning, and the temperature of the engine has decreased. The most surprising thing is that the scooter gained an extra 5 kilometers per hour in top speed (50cc). My friend, who also has the same scooter, noticed the exact same improvements when he used Amsoil. I will also use Amsoil in my Yamaha Grizzly 700 ATV and will provide feedback. These lubricants are incredible.

I changed the engine oil in my Yamaha Grizzly 700 from Yamalube 10W-40 synthetic to Amsoil Synthetic Dirt Bike Oil 10W-40. The engine runs smoother and sweeter, and I also noticed a significant decrease in engine temperature. The morning start-up at a temperature of -8°C became easier and smoother. I also used AMSOIL Synthetic Marine Gear Lube 75W-90 in the differentials of the Yamaha Grizzly 700.

In the end, I have decided to use only Amsoil lubricants in all of my vehicles. They are unique with incredible properties, and I regret not knowing about them for so long.
