Bad engine in your auto ? Car problems ? What are the basic tests & tools employed by your mechanic & what can ( for the most part go wrong ) ? Get your charge card out of your wallet. Check oil level. Add oil if dipstick shows it at or below the ADD mark. Change oil if it is "dirty" or if you feel that a change is due. Depending on driving patterns and personal preferences some change oil by time - how many months , while others do it by mileage driven. A vacuum test can help you spot vacuum leaks in the intake manifold ( or in older vintage automobiles and vehicles - the carburetor). As your car ages it needs more frequent service. The engine requiring an oil-and-filter change at 6,000 mile intervals when new, may require it at 4,000 mile intervals after 50,000 to 60 k. Engine wear permits greater leaks of combustion products and exhaust gasses into the crankcase thus contaminating the oil. In the case of diesel engines - such as VW diesel motor, the Volkswagen diesel develops much higher compression than a gasoline engine variety setup. The typical gas engine will run satisfactorily with cranking compression as low 90 psi whereas the VW Diesel should withstand pressures in the ranges of 400 to 500 pounds per square inch to raise the temperatures high enough to ignite diesel fuel to power up the engine. On top of that not a lot of complexity or of engine & motor damage are incurred or involved. Many motorists use the seasonal changes as a reminder to make other checks. Always note and remember that these are simply "guidelines". If for instance, your car begins to show symptoms of needing a tuneup in the middle of August, you should not wait until late fall to do the work. For example what of engine oil burning as a common automotive issue & problem ? In the case of VW diesel engines its an entirely different manner than standard gasoline powered engine powerplants. Conventional compression gauges with their 250 to 300 psi limit will not do. VW supplies a model that not only reads 600 lbs per sq inch, but provides a roll of paper and an automatic marking pen ( in place of standard indicator needle) to provide a permanent record of compression readings. Of course in the new millennium electronic versions are available at your local Canadian tire outlet store. Car oil varies from four quarts to seven. The owner's manual and markings on the dipstick will inform you how much oil that your auto requires and needs. The thickness of an oil ( also called or referred to as its viscosity). The standard procedure by the society of Auto Engineers (SAE), is to number the oils according to viscosities. Generally the higher the number , the thicker the oil. All numbers are preceded by the letters SAE, the abbreviation for the accepted professional and trade society that sets "the standard" employed. If the number is followed by the letter "W" , the thickness was measured at zero degrees (0), if no letter follows then it was done at 210 degrees F. Engine oil loses its ability to lubricate properly , when it becomes contaminated with dirt drawn in with outside ambient air. metal particles from engine wear and of course by products of combustion. No doubt about it. In today's modern world of 2010 , most people are dependent on their vehicle - be it car, truck or SUV for basic transportation & transporting them to and from their job or place of employment for their basic income. Take care of your auto & will serve you reliably & in good stead.
