In Texas, the Texas Department of Public Safety has 3500 police cars that used to change their oil every 2,000-3,000 miles with other oils (severe service) have used AMSOIL for the past 10 years changing AMSOIL oil and filters every 20,000 miles.

Sure. I've had several DPS vehicles contact me looking for AMSOIL as they ran low and needed oil and filters. They told me that all the DPS cars use AMSOIL and change at 20,000 mile intervals. I've spoken to several DPS and they tell me how happy they are to run AMSOIL at 20,000 mile oil change intervals. Feel free to contact them and ask.

Here is an article:
The Texas Department of Public Safety
and Amsoil Synthetic Lubricants (Inc.)
conducted a field test to determine the cost effectiveness and engine wear protection provided by AMSOIL products in severe service applications.
Amsoil 5W-30 Motor Oil and Super Duty Oil Filters were installed in five police vehicles. No oil changes were performed during the 24,000 mile testing period.
AT the 12,000 mark, the oil filters were changed and one quart of oil was added to each vehicle to replace the oil lost with the filter change out.
The Texas Department of Public Safety police fleet vehicles were 1999 Ford Crown Victoria patrol cars. The initial cost breakdown with AMSOIL products is as follows:
Oil Cost $4.00/qt x 5 qts = $20.00
Amsoil SDF Oil Filters $7.00 x 2 = $14.00
Oil for filter change (one quart) $4.00
Labor $10.00 x 2 = $20.00
Total: $ 58
Totals Based on US. Commercial
ASL Pricing Per Case.
Using conventional petroleum oil for
the standard 3,000 mile drain intervals,
the Department invests $176 per vehicle
over the 24,000 mile testing period.
Oil Cost $1.75/qt x 40 qts = $70.00 Oil Filters $3.25 x 8 = $26.00
Labor $10.00 x 8 = $80.00 Total $ 176 Without even taking into consideration the superior protection and performance
AMSOIL motor oil offers over a conventional lubricant,
The Texas Department of Public Safety saves $118 per
vehicle in lubricant expenses alone.
When extending these savings to all nine vehicles in the
Canyon office, AMSOIL motor oil
saves the department $ 1062.
Taken even further,
If all 100 vehicles in the district switched to AMSOIL
motor oil and SDF oil filters for drain intervals of 24,000
miles, they would save
If all 3,000 vehicles statewide made the switch,
the State of Texas Tax payers would save a staggering
in lubricant costs alone ... not including the reduced
amount of fuel consumption that accompanies Amsoil
Synthetic Lubricants use > in all motor vehicles.
Spectra Analysis results of one of the test vehicles showed
that the superior lubricating properties of AMSOIL
Synthetic 5W-30 Motor OIl provided outstanding protection
and performance throughout an extended drain life. AMSOIL
Synthetic 5W-30 retained its stable operating viscosity
throughout the trial, and contaminants such as iron and
lead were virtually nonexistent.
YOU are loosing money by being conditioned to think that it
is "Normal" for repair costs to be high ...
It is not ...
Repair costs being high are a result in using medium to
mediocre products to protect that are not capable
of doing the job that they were sold to do.
AMSOIL INC., together with Dealer Jerry Criswell and the Texas Department of Public Safety, conducted a field test of its 5W-30 Synthetic Motor Oil and SDF Oil Filters. Installed in five police fleet vehicles, the lubricant was sampled and tested at various intervals. The goals for this particular field test included demonstrating that the use of AMSOIL Synthetic Motor Oil for extended drain intervals would not only result in lower lubricant expenses, but also superior wear protection. When taking advantage of the extended drain intervals of AMSOIL Synthetic 5W-30 Motor Oil, it costs the Texas Department of Public Safety $57.20 to lube one vehicle (5 quart capacity) for 24,000 miles:
2002 Figures: 2007 Figures:
Oil Cost ($3.90/qt x 5 qts) $19.50 Oil Cost ($4.05/qt x 5 qts) $20.25
SDF Oil Filters ($6.90 x 2) $13.80 Ea Oil Filter ($7.90 ea) $7.90
Oil @ filter change (one qt) $ 3.90 No add'l filter change $0.00
Labor ($10.00 x 2) $20.00 Labor ($10.00 x 1) $10.00
If using a conventional 5W-30 lubricant for standard 3000-mile oil and filter drain intervals, it would cost the Texas Department of Public Safety approximately $176 to lube one vehicle (5 quart capacity) for 24,000 miles. For example:
Oil Cost ($1.75/qt x 40 qts) $70.00
Oil Filters ($3.25 x 8) $26.00
Labor ($10.00 x 8) $80.00
Without even taking into consideration the superior protection and performance AMSOIL motor oil offers over a conventional lubricant, the Texas Department of Public Safety saves $118.80 per vehicle in lubricant expenses alone. When extending these savings to all nine vehicles in the Canyon office, AMSOIL motor oil saves the department $1069.20. Taken even further, if all 100 vehicles in the district switched to AMSOIL motor oil and SDF oil filters for drain intervals of 24,000 miles, they would save $11,880. (almost all DPS vehicles throughout Texas now use AMSOIL)
Of course, extended drain intervals are no bargain if they compromise engine protection. Even though it was in service 13 times longer than the previous conventional oil, the rates of wear with AMSOIL Synthetic 5W-30 Motor Oil were significantly lower. The oil analysis results of one test vehicle are shown below, and the results were typical of all five test vehicles. The first line represents the petroleum oil baseline at 1,749 miles. As one can see, the rates of wear with AMSOIL 5W-30 are significantly lower than the petroleum oil, even at extended drain intervals.
Note: Oil analysis is recommended for all fleet applications to determine proper drain intervals.
