Video: Rethinking Synthetic Oil Change Intervals

FREMONT — Host, Sarah Rutan: Many high-end car manufacturers now recommend a 10,000-mile oil change interval, but is this really a good idea? Today we’re in Fremont with Diamond Certified Expert Contributor Eduardo Porta of Fremont Foreign Auto to learn more.

Diamond Certified Expert Contributor Eduardo Porta: I have a tip for you. Whether you’re my customer or not my customer, it’s: An oil change today, it’s a big deal. All these newer cars, since 2008 and newer, require synthetic oil. And the manufacturers are telling the people out there to do an oil change every 10,000 miles. So wrong!

Companies from the oil companies recommend that the synthetic oil is being changed every 7,500. All the vehicles are being changed at 10,000 miles. Cars above 100,000 miles, they have all kinds of lubrication problems in the engines. I have cars in here, they come, BMUs, Mercedes, Hondas, Nissans, they come with the internal engine lubrication issue due to the extending 10,000 miles oil intervals. Really wrong.

Don’t do that to your car. Read about it. Go to the oil manufacturer and read about it. Not the car manufacturer, but the oil companies. Because cars, they don’t make oil. Oil companies are the ones that are responsible for these oils.

And after 7,500 miles on a synthetic oil, you will break the viscosity and then you’re running with bad oil inside the motor. In the long run, it’s not good. You have a lot of expenses. I have cars in here, you spend up to $6,000.00 in repairs because there’s oil not being changed in 7,500 miles. You know, you don’t have to take my word for it. Do some research out there and then keep your engine clean.
