Performance Claims for 0W-20 Synthetic Oil

It’s easy to say it will offer great protection.  Every manufacturer says they’re the best.  Search AMSOIL vs Mobil 1 on a search browser.  Read the claims for greatness.  The truth in performance is in independent testing.

In 2013 and 2014 AMSOIL put out a challenge to prove just how effective the 0W-20 synthetic oil is at keeping sludge out of the engine and keep an engine running without wear and tear on the metal parts.  In light of that, a cab company in Las Vegas took the challenge.  They experienced oil breakdown and excessive wear (sometimes engine failure) at 5,000 mile oil change intervals using a competitor’s synthetic oil due to excessive idling.  Stop-and-go traffic continuously in summer months contributed to the problem.  Could AMSOIL 0W-20 do better in such tough conditions meant to boil and breakdown engine oil?

The Test Criteria

The cab company added AMSOIL 0W-20 Signature Series engine oil to six test vehicles that were run up to 24-hours every day.  The only time the engines were turned off was to change personnel or refuel the cab.  Ambient air temperature was around 100 degrees or more during the day.  And the cabs were constantly loaded with passengers and luggage while driving.  The engine oil was scheduled to be changed at a minimum interval of 900 hours of service, but that averaged to be 1,005 hours (equivalent to ~15,000 miles) during the test in actuality.

Note: 900 service hours for an average motorist would be equivalent to ~19,000 miles of city driving and ~43,000 miles of highway driving.

The Test Results

After 7,033 service hours (~102,000 miles) in an 18-month period, one of the cab company’s 2010 Dodge Chargers was torn down for inspection.  It averaged 14.6 miles per gallon of fuel economy over the test cycle, while the estimated mileage should be 21 miles per gallon combined city/highway driving.  So as a matter of speaking, that tells you how tough the test cycle was for stop-and-go traffic and excessive idling.  It reduced the mileage by 30% or more.

Engine components were graded on a 10-point scale.  A “ten” is the best, while “one” is the worst.

These results speak volumes:

  • Oil pan sludge deposits: 9.6 / 10
  • Oil pan varnish deposits: 9.0 / 10
  • % clogging of oil screen: 1 (meaning it only lost 1% of its ability to screen the oil for large contaminants)
  • Cylinder head sludge deposits: 9.6 / 10
  • Front engine cover sludge deposits: 9.8 / 10
  • Camshaft lobes: no visible wear, no flaking or spalling noted
  • Front engine cover varnish deposits: 9.6 / 10
  • Front engine cover seals: no noted hardening or cracking with only very light varnishing, no leaks noted.

A Practical Approach

The engine oil kept the Dodge Charger running smooth with no issues for over 100,000 miles during the test.  Likewise, the AMSOIL 0W-20 synthetic oil stood up to the harsh environment, exceeded the oil change intervals in excess of double (sometimes triple) of the manufacturer recommendation.  In other words, it didn’t break down.  Accordingly, it didn’t cause wear and tear on the vital components.

What You Need to Know about AMSOIL’s 0W-20

AMSOIL 0W-20 engine oil is offered in three versions based on your driving and service needs:

  • Signature Series – offers up to 25,000 miles, 700 service hours, or one year of service whichever comes first for normal motorists not operating under severe duty conditions. If you plan to use it in a commercial setting (excessive idling, hauling, or towing), the mileage rating is reduced to 15,000 miles.  But it stays with 700 service hours and one year.  If you have a modified engine or run an alternative fuel (like E85, CNG, propane, etc.), follow the severe duty rating also.  Be sure to change your filter at 12,000 miles if you are using a brand other than the AMSOIL Ea series for best protection, and always change your filter when changing the oil at the end of the service life.
  • XL Series – The XL series offers up to 12,000 miles between oil changes or one year of service.  If your schedule doesn’t fall under the severe duty category, this is a great option.   Follow the same guidelines for changing the filter as when you change the oil.
  • OE Series – The OE series follows OE manufacturer recommended intervals between oil changes.  Your vehicle may be recommended for 5,000 – 7,500 miles between oil changes under normal use. Follow your manufacturer guidelines and change the filter when you change the oil.

In Conclusion

The AMSOIL 0W-20 synthetic oil is a great option for all vehicles. Whether you just use your car or truck to commute, use it in a commercial setting requiring severe duty, or somewhere in between, the three options will offer you maximum protection and keep the oil change cost down.
