Oil Change Service
Think of motor oil as your vehicle's blood. When human blood get contaminated with disease, the body gets sick and stops functioning normally. When your vehicle's oil gets dirty and sludgy because you neglect to have the oil changed, your car or truck will inevitably suffer serious engine problems.
Major Wear and Tear
Overused oil quickly breaks down and can no longer lubricate active engine parts. Consequently, the integrity of these moving parts deteriorates rapidly, shortening the life of your transmission and your engine.
Rust and Corrosion
During the breakdown of oil, chemicals are released that interact negatively with heat and oxygen to form corrosive acids and compounds that are destructive to engine and transmission materials. In addition, corrosive compounds promote varnish and sludge build-up deep inside the engine that prevents critical clearances among all moving parts. Seized pistons, stuck valves and increased oil consumption will result if you don't have your oil changed every 3000 miles.
Clogging and Reduced Oil Pressure
Infrequent oil changes leave sludge and carbon deposits that clog oil passageways and oil pump screens. This causes a drop in oil pressure and insufficient oil supply to your vehicle's engine. Without enough oil, any engine will overheat and seize.
A Poorly Performing Vehicle
Carbon deposits clog PCV valves, EGR valves and cause engines to run rough. In addition, stuck PCV valves produce extreme crankcase pressure that leads to leaking oil gaskets and seals. A knowledgable Duluth auto repair service like DMA Automative in Duluth GA will check PCV valves to determine whether they rattle when shaken. PCV valves that do not rattle should be replaced ASAP. Technicians at DMA Automative will also test PCV valves while the car is idling. A vacuum should exist at the valve inlet after the PCV valve has been removed from its cover.
Thermal Breakdown of Motor Oil
Once past serviceable life, motor oil starts breaking down thermally. Engine heat naturally decreases oil viscosity, a characteristic of new engine oil providing adequate cushioning for moving engine parts that rub together. Degraded, dirty oil is thin enough to slip past rings and seals, where it ends up burning in the combustion chamber. Increased oil consumption and smoking exhaust are classic signs of thermal breakdown in motor oil.
An oil change costs less than $50 and only takes about 30 minutes when performed by an experienced Duluth auto repair technician. Extend the life of your vehicle and keep maintenance costs to a minimum by contacting DMA Automative today.
