Hi, my name is William (Willie) Parsons and I am the owner of Synthetic Motorsports. I was born December 1969 and raised in Oscoda Michigan. I have 6 years Aircraft Maintenance as C-130 Crew Chief, followed by more than 20 years as Command Post controller, training manager, and superintendent and finally the Command Post Career Field Manager for the Air Force Reserves. I retired from the Air Force in 2015 with nearly 27 years of service to our nation.

I have been in the synthetic lubricants and bolt on replacement parts since 2009. I initially started out offering AMSOIL Synthetic Lubricants on the Duramax Forum (a.k.a. mrmanners) after buying my first Duramax that year. While the initial thought was to have an AMSOIL business as a hobby, it quickly turned into a part-time job in the mornings and evenings before and after work. Since then, I slowly grew my business into what Synthetic Motorsports is today.

When I am not working, I enjoy many things from the outdoors to cooking. I am also a cigar aficionado. I am married to my beautiful wife Julie from Eastman GA and have a teenage daughter.

I have prided myself on providing excellent customer service to every customer that shops with or asks question from Synthetic Motorsports. That philosophy carries over to the sales staff here as well. I look forward to working with you. If for any reason you would like to reach me, you can call 1-888-563-5143 or email me at

Thanks for your time and God bless.

Synthetic Lubricant Information

Synthetic lubricant verses conventional lubricant usage has become a hot topic over recent years due to the increasingly improving quality of conventional and synthetic blend lubricants. New technology has made it possible for manufacturers of conventional lubricants to improve the overall quality and consistency of their lubricant additive packages.

However, conventional lubricants are still refined and developed in such a way that leaves the molecular structures very unstable. Even though they will stand up better than older versions, they will lose viscosity and total base number (TBN) levels much quicker than the synthetics for the given applications.

Full synthetic lubricants are also not created equal. When comparing synthetic lubricant brands, it is important to research the recommended service intervals. A manufacturer's recommended service intervals can give a customer an idea of how long their lurbicants are designed to last. When a manufacturer sets their advertised service interval limits, they do so according to lab and real world testing results that have shown that their synthetics will last a certain number of miles before viscosity and TBM break down results in lack of overall protection.

AMSOIL Synthetic Lubricants offer the highest level of protection, service interval length and cost effectiveness of all of the synthetic manufacturers out there. AMSOIL pioneered the synthetic lubricants industry in 1972 and has remained an industry leader in the research and development of synthetic lubricants for every possible application.
