A Changeover To All Synthetic Lubes

How this business decision resulted in a substantial savings for one trucking company

The people at Farstad Oil recommended that Lesmeister Transportation go with Mobil Delvac 1 ESP 5W-40 - a fully synthetic, “supreme performance,” heavy duty diesel engine oil that helps extend engine life while providing long drain capability and potential fuel economy savings for modern diesel engines operating in severe applications. The fleet began testing the oil. It ran the oil in five tractors over a two-year period and compared the performance results to the two years prior to switching from a conventional heavy duty diesel engine oil. The five rigs were on the same routes with the same drivers as they had been prior to converting.

Pleased with the test results of the synthetic motor oil, Lesmeister Transportation made the transition to a fully synthetic fleet. The process to convert the entire fleet took less time and was less complex than Lesmeister had anticipated.


One of the most obvious benefits of switching to Mobil Delvac synthetics is the extended oil drain interval, which helps reduce the fleet’s oil consumption and service downtime – and costs, Lesmeister says.

“In terms of total cost savings over the past 10 years (when the switch was made), I estimate we have easily saved more than half a million dollars,” he says. “We aren’t buying as much oil as we previously were because of the extended oil drains,” adds his wife Mary, the company’s treasurer. “At the same time, we are achieving increased fuel economy savings, which obviously impacts our bottom line. And, we are creating less waste oil.”

The other obvious benefit, Lesmeister notes, is the performance and protection the fleet gets during cold starts.

“Since Barry switched our fleet over to the synthetic Mobil Delvac 1, my job has been a lot easier,” says Bob Morris, Lesmeister’s shop foreman and lead mechanic for more than 20 years. “Our trucks always start in the morning, whether they are here in our lot plugged into heaters, or at truck stops totally exposed to the elements.”

All vehicle maintenance is done in-house except for major warranty work at the company’s own maintenance facility.

As a small business owner, Lesmeister says there is another benefit to his all synthetic lubes fleet, but this one is that is hard to put a price tag on: peace of mind. “You’re always going to have challenges as a business owner,” he says. “But knowing that our trucks and our drivers are well protected with Mobil Delvac 1 synthetic oils is something that gives me a lot of confidence and peace of mind.”

For him and his wife, the belief in synthetic oils extends beyond their trucking business. They run only Mobil synthetic oil in their personal vehicles.

In his 40 years of trucking, Lesmeister has made plenty of decisions. Judging from his success today, most of them have been smart. “One of the best decisions I have ever made was upgrading our entire fleet to Mobil Delvac 1 synthetic oils. “It was 10 years ago when we made this decision, and it continues to pay off for us every day.”
