How thin is 0W-8 motor oil? Toyota now calls for 0W-8 motor oil, which was only recently approved for use by the API. Can it actually protect the engine? Do Toyota dealerships actually install 0W-8 when they do the "free" oil changes? In this video, we put used oil analysis to work to get the answers to those questions, and the results are quite shocking!

Speaking of thin oils, we also took a sample of the CVT fluid from the transmission as well, so check out those results at the end of the video.

In a previous video, I changed the oil in my daughter's new Toyota Corolla before it had 1,000 miles on it. Here's the link to that video:    • AVOID the ONE MISTAKE Almost EVERYONE...  

Then we changed it again after about 3,000 miles. Here's the link to that video:    • NEW Engine BREAK-IN: Truth or MYTH?  

At both oil changes, the Toyota recommended 0W-8 was not yet available because the American Petroleum Institute (API) had not yet approved the use of 0W-8 oils in the US.

Now that it is time for the first "free" oil change at the dealership, are they going to use the Toyota 0W-8 oil? By taking a sample of the oil from the engine AFTER the oil change with a vacuum extraction pump we find out!

Since we are talking about oil changes, here are some links to previous videos on oil filters and oil change procedures:

The oil analysis results showed that the Toyota Genuine 0W-16 did a great job. It is available at https://amzn.to/3t1iN5H
