AMSOIL #1 Choice for High Performance Supra


I chose AMSOIL for one reason. It is the best bar none. A friend of mine sent it out to a lab and had it analyzed and compared it to a few others.  AMSOIL topped all others I chose in the past. This was something that was important to me because good oil is like having good blood.  It is the life in your veins. Anytime someone wants to know what oil I use, I tell them AMSOIL is the #1 choice.  Whether it be for a normal application or high performance street or drag race use, this is the oil to use.

Angler Is "Hooked" On AMSOIL
Guide Service Owner and Tournament Angler

David A. Zgrabik of Cleveland, Ohio, owns a guide service and is also a tournament angler. His success depends on the reliability of his equipment. He says he has always used quality oils, but has never seen the performance and sheer benefits from other products like he has seen from the AMSOIL product lineup. After starting to run AMSOIL Series 2000 2-Cycle Racing Oil, I noticed considerably less smoke at start-up, improved idling and more power, David said. I even have an unexplainable 200 rpm increase! Davids tow vehicle is another important part of his business.

 I travel all over when I'm fishing and doing other promotional work, David said. After installing AMSOIL engine oil and an AMSOIL filter, I noticed a 10-15 degree temperature drop while the engine was operating. I was just amazed at how well it was working. There was also an increase in fuel mileage. There is no way I would do without my AMSOIL motor oil now!
