Toyota 3.0L MZ Engine

Despite settling lawsuits, Toyota has staunchly maintained that the problems are the owners fault. They are lying.

Toyota advertised this generation of 3.0L engines as having good fuel economy without sacrificing on performance. They didn't mention that the oil would gel into a thick goo.

Any engine gummed up with oil usually needs to be replaced, but if there's a chance of repairs it will still cost thousands of dollars.

Engine Sludge Settlement

In 2007, Toyota settled a class-action engine sludge lawsuit that covered an estimated 2 to 5 million Toyota and Lexus vehicles made between 1997 and 2002. As part of the settlement, Toyota agreed to repair the 'sludged-up' engines for up to 8 years from the time of purchase.

The automaker has staunchly maintained that the problems are the owners fault.
