- Why do most race teams use Mobil 1 and not Amsoil?
- Amsoil does NOT manufacture any of their oil components, including base stocks.
Item 1: Two words: Brand recognition. Mobil has a much bigger advertising and marketing budget, hence, a much higher profile.
Item 2: As long as Amsoil controls QC/QA and the base stocks are top-grade, who cares? You think all ExxonMobil gasoline is refined from crude from the same oil field? As long as the end-product performs as expected, I really don't give a flip about how it came to be.
