The use of obsolete oil is not something consumers think about when they get an oil change, even if they change their own oil. Lately though, this concern has been brought to our attention. Modern cars are designed with much tighter internal engine clearances than in years past so using the correct oil is critical.
If your starburst symbol oil label does not specify GF-5 SN it is not suitable for most cars newer than 2011. The labeling on the oil contains “obvious and unambiguous language” regarding its intended and appropriate use. I am sad to report many shops don’t understand the consequences of incorrect oil labeling.
ALL cars have specific oil that needs to be used or damage will occur! This is why some cars’ engines have 200,000, 300,000 or even 400,000 miles on them while others only get half that many miles. The use of incorrect oil can also dramatically lower fuel mileage and cause damage to systems that result in the increased emissions of toxic substances and damage to emission control systems, including catalytic converters and oxygen sensors.
If you have heard the term “sludge” and I hope your never do in relation to your own car, it is caused by two things; waiting too long to change the engine oil or using incorrect oil for that specific application. Be warned also that European cars have even stricter additive packages that if not adhered to, will really wreak havoc on the internal parts of the engine.
I recommend knowing what oil is recommended for your car and asking questions when you arrive at your trusted automotive shop. AAA shops have to adhere to higher standards and are held accountable for their actions. Be an informed consumer, not one with a broken car.
