Kwik Kar Marsh is your one stop shop for all you automotive needs. Every time you turn your engine on, it continuously generates acids, combustion gases, water vapor and fuel by-products that end up in your oil—your engine’s bloodstream.
Unchecked, these contaminants may eventually form deposits that can clog oil passages, gum up moving parts and, ultimately, reduce engine responsiveness. Tighter tolerances = less tolerance for dirt and deposits.
Here’s an infograph of what your car produces for every 100 gallons of gasoline used.

For every 100 gallons of gasoline burned in an engine, these by-products are produced:
- 90-120 gallons of water
- 3-10 gallons of unburned gasoline
- ½-2 pounds of soot and carbon
- ¼-1 pound of varnish
- 1-4 pounds of sulfuric and nitric acid
A measurable percentage of these by-products end up in the crankcase oil, potentially contaminating the oil. When dispersed properly in oil, the filter can trap the larger particles. Contaminants too small to be filtered are removed with the engine oil change.
Whether you use conventional oil or synthetic, changing your oil every 3,000 or 5,000 miles is necessary to keep your car running properly.
