Troy Michigan Police and City Hall Fleet
This letter is a summary of a letter written by the Superintendent of the Motor
Pool. Please contact us if you would like the full letter mailed or faxed to
you.
The City of Troy, Michigan has switched its entire Police and City Hall Fleet (approximately 350 vehicles) to AMSOIL Synthetic Lubricants.
History: In the past, all marked and unmarked police vehicles would come in monthly for an oil change, lube and safety check. As a test, we switched two marked Chevrolet Caprice vehicles over to 100% synthetic AMSOIL engine oil and extended the drain intervals to 20,000 miles, with a new oil filter installed at 10,000 miles. The vehicles were still scheduled to come in monthly for a safety inspection (tires, brakes, suspension, lights, etc...), but the oil is not drained, only a sample is taken. When the two test vehicles reached 70,000 miles, the City of Troy technicians removed the oil pans and also removed the main and rod bearings to check for wear using the plastic gauge test. The bearings showed very little wear. the same procedure was performed on two marked cars, same year, make and model, using petroleum oil. The wear on the two vehicles with petroleum oil, changed monthly at about 2,500-3,000 miles, showed slightly more wear in the plastic guage test. The results were well within specifications in both cases.
Currently the city is using all Ford Crown Victorias in its police fleet. With the help of oil analysis, we were able to extend our oil changes to 18,000-20,000 miles with a new filter installed at 9,000-10,000 miles. We are currently using AMSOIL synthetic engine, transmission, and rear differential oil in all vehicles serviced out of the city hall facility.
SAVINGS: Savings have been noticed due to the decrease in number of oil filters and quarts of oil purchased and disposed of . Labor time to complete a preventative maintenance (A or B) on a vehicle has been reduced, allowing up to 50% more vehicles to be serviced each day. To date, we have not had to re-build an engine or transmission with the new extended oil change intervals.
Material and maintenance cost for the 4 units with conventional lubricants and filters was $1,052.11. With AMSOIL Lubricants and Filters, the total was only $638.20 - nearly 40% saved per mile!
AMSOIL saves in labor and material costs because it can be used many thousands of miles longer than conventional lubes.
Arizona Fire Dept switches to AMSOIL
Dale
Wagner, Chief mechanic for two for two Prescott, AZ fire dept's (the Central
Yavapai Fire District and the City of Prescott Fire Dept.), knows the importance
of a well-maintained truck fleet.
After switching to AMSOIL 15w-40 Heavy Duty Diesel and Marine oil in two fire trucks, he sent oil samples to Cleveland Technical Center every 200 hours or sooner.
After 1,000 hours, the lab questioned his frequency of tests. "I was expecting to find failure in the oil after five drain intervals had passed," said Wagner, "I realized that AMSOIL lubricants provided unsurpassed protection on engine parts when, after 1,000 hours the AMSOIL had better test results than my previous oil had straight from the container."
Before switching to AMSOIL, Wagner said he had recurring down-time while repairing the trucks. Not so with AMSOIL. Wagner also says he was able to reduce his oil change time.
AMSOIL 5w-30 Motor Oil and Super Duty Filters were installed in five police vehicles. No oil changes were performed during the 24,000-mile testing period. At the 12,000-mile 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 Dept 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 @ filter change (one quart) | $4.00 | |
| Labor | $10.00 x 2 = | $20.00 |
| TOTAL: | $58.00 | |

The Texas Dept of Public Safety invested $58.00 per vehicle to install AMSOIL products. Using conventional petroleum oil for the standard 3,000-mile drain intervals, the Dept invests $176.00 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 2 = | $20.00 |
| TOTAL: | $176.00 | |
Without even taking into consideration the superior protection and performance AMSOIL motor oil offers over a conventional lubricant, the Texas Dept of Public Safety saves $188.00 per vehicle in lubricant expenses alone.
When extending these savings to all nine vehicles in the Canyon office, AMSOIL motor oil saves the department $1062.00. 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 $11,800.00. If all 3,000 vehicles statewide made the switch, the state would save a staggering $354,000.00 in lubricant expenses alone.
Oil 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 service life.
AMSOIL Synthetic 5w-30 retained its stable operating viscosity throughout the trial, and contaminants such as iron and lead were virtually nonexistent.
