Believe it or not there is a motor oil which only needs to be changed in Trucks every 35,000 miles; yes exactly, that is what I thought; NO WAY! Kendall Motor Oil for trucks is claiming a 35,000 mile interval between oil changes at;

this is spectacular and many truckers swear by this stuff. Lucas Oil Additives, which we have been testing in our Corporate Command Center has declared a 25,000 interval frequency.

I see a problem as technology for oil becomes better with companies like Speedco for truck oil changes and for companies like Jiffy Lube for cars. Cars average frequency for oil changes is over 4,000 miles even though the companies who do oil changes have gotten together and decided that the industry would proclaim 3000 as the best policy.

Even National Oil and Lube News in Amarillo and ASO magazine seem to be printing those figures in their publications. Where is the reality? Sometimes it is better to change the oil and not the filter. New filters do not work as good as filters which have been in there for a while. That has been proven. What will oil change facilities do when the cars do not have oil in them? For instance a motor that is Hybrid Electric or Hydrogen Cell. Think on this.
