AMSOIL INC. introduced AMSOIL Synthetic 10W-40 Motor
Oil and became the first company in the world to market
and manufacture an American Petroleum Institute (API)
rated synthetic motor oil. In 1975 AMSOIL introduced
a synthetic diesel oil, and with it, coined the term
"extended drain intervals."
Since then, AMSOIL synthetic diesel
oils have been used as extended drain lubricants in
transportation, equipment and stationary engine applications.
In every industry, they have proven effective in improving
engine durability and fuel economy. AMSOIL customers
report significant savings realized through reductions
in downtime, parts replacement, lubricant replacement,
lubricant disposal and fuel consumption. Fleet demonstrations
and independent testing confirm what AMSOIL customers
report: using AMSOIL synthetic diesel oils saves money.

motor oil. Whether you want the fuel economy benefits
and ultra-cold temperature protection of a diesel-formulated
5W-30 or the tried-and-true protection of a 15W-40,
you just can't beat AMSOIL synthetic motor oils.

testing shows up to 43 percent less wear with Series
3000 than with the other oils tested.
3000 also offers 12 TBN protection for serious long-term
acid control and a stay-in-grade formulation to protect
moving parts from high-temperature contact and wear
throughout the oil's service life.
Series 3000 is formulated for significant
fuel savings, boosting fuel economy far beyond what
it would be with a conventional 15W-40 oil.
