2003 Ford Ranger 6 cyl Two Wheel Drive Automatic

i had a friend of mine who works on cars for a living tell me that american cars are made using low quality metals and that after 50,000 miles the metals have worn so much from vibration that instead of a thin oil now I use 5/20 synthetic he said switch to a heavier oil and since there will now be more metal dust in the oil also use a really high grade oil filter. Is there any fact to this?

Listen, I have worked on cars for over 30 years. I assure you that American cars are as good as any car on the market if not better. You can get a lemon in any model. I presently drive a 93 Dakota with 220K miles and still use the same oil that I started with. Do what the manufacturer recommends. There is no truth to it. If imported steel is stronger, why did Toyota have a massive recall / buy back because the frames rotted out on their trucks if their steel is better? American steel is the strongest and of the highest quality in the world. Just keep changing the oil and you'll be fine.
