SAN CARLOS OIL CHANGE SERVICES:

Auto Repair Experts - San Carlos, Belmont, Redwood Shores, Redwood City, Foster City - A+ Japanese Auto Repair

Most vehicle manufacturers recommend an engine oil change every 3,000 to 5,000 miles. The same mileage in terms of time intervals is an oil change every three to six months. It is important for all drivers to note, because the scheduled service for oil changes might look a little different in your owner’s manual. For example, many owners’ manuals recommend changing the oil once a year or every 7,500 miles – sometimes higher! Why this contradiction you ask?

Read the fine print, and you will discover that the factory recommended once a year or 7,500 miles oil change is for vehicles that are driven under the normal driving conditions. However, what most of us think as "normal" driving conditions are actually "severe" driving conditions.

Definition of “ Severe” Driving Conditions taken from one owners manual:“Frequent short trips (less than 10 miles, especially during cold weather), stop-and-go city traffic driving, driving in dusty conditions (gravel roads, etc.), and driving at sustained highway speeds during hot weather."

Does this sound like your commute? If so, you might need to follow instructions for "Severe Service” in your owner’s manual. Your engine oil and filter changes should be performed every 5,000 miles or six months if you live and commute in California like the customers and mechanics at A+ Japanese Auto Repair. This is the oil change interval A + Japanese Auto Repair Inc. recommends to our clients living in San Carlos, Belmont, San Mateo, Redwood City, Foster City, Redwood Shores, Woodside and surrounding areas.

Oil Analysis

If we were to monitor the engine conditions of an average clients vehicle driving in the conditions described above with 5,000 miles oil change intervals, we would see some interesting things. The analysis of engine is performed as follows:

Oil samples are sent to a laboratory that then analyzes the oil's viscosity and acid content. (Fig A.)

Oil is then burned in a spectrometer that reveals various impurities in the oil. From all of this, a detailed report is generated that reveals the true condition of the oil. (Fig B.)

After the above Engine Oil tests are performed a comprehensive report is sent back to you showing the information above and the impurities found. (Fig C.)

Don’t Forget the Oil Filter:

Today’s automotive engines main line of defense against premature wear and/or damage is the oil filter. The oil filter's job is to remove solid contaminants, such as carbon, metal particles and dirt from the oil before they can damage bearing, journal and cylinder wall surfaces in the engine. The more dirt and other contaminants the filter can trap and hold, the better.

In modern engines, the oil that is siphoned by the oil pump is pushed through the filter before it goes to the crankshaft bearings, cam bearings and valve-train. This is an efficient way of removing the solid particles from engine oil and it assures only filtered oil is supplied to the engine. Over time, accumulated dirt and debris trapped by the filter begin to obstruct the flow of oil. The filter should be changed before it reaches this point. The oil filter is always changed as part of the engine oil and filter change service at A+ Japanese Auto Repair. Below is a picture of the filter element removed from the engine’s oil filter housing. Deep within in the filter element you can see the metal flakes and other contaminants this filter has eliminated from the oil system (Fig D.)
