Yes, oil changes are a scam.
We're still told to have our vehicle's oil changed every 3,000 miles.
That's fantastic news for big oil - if we pay just $30.00 for each oil change and our car lasts 100,000 miles, that's $1,000.00. Much of that money is literally being flushed down the drain.
Lab tests reveal the quality of motor oil remains about the same whether we change our oil every 3,000 miles or 15,000 miles. In other words, oil doesn't break down as fast as we're led to believe.
Motor oil's detergents clean the inside of the vehicle's engine and as a result can turn engine oil dark. The color of the oil has little to do with its current quality and/or lifespan.
Some say all-synthetic oil never sludges because additives are used to make the oil stronger and provide higher heat dissipation. That means in theory, you could go the entire life of your vehicle without an oil change (although I don't want to be the guinea pig on that test).
What's interesting is the owner's manual of my car recommends changing oil every 15,000 miles in Europe (yet every 3,000 miles here in the States). When I asked the dealership's service center about this, they said the car's emission system is different - I'm not buying that excuse.
But the best proof is personal experience. I've driven two Toyota RAV4s well over 200,000 miles (each), and I only changed the oil at 20,000 intervals. And both car's engines were running just fine when I traded in for new RAV4s.
P.S. Have a look at my other investigations, videos and podcasts and get the real truth about life...
