He’d taken the Tacoma out for a test drive with some potential buyers when one complained of smelling burning oil.
It turned out this was part of an elaborate ruse.

This Seattle man had someone try the ‘dirty oil trick’ on him with his Toyota Tacoma
Anthony Nguyen took to TikTok with a bold statement:
“Y’all, I think I almost got scammed.”
Sounds pretty scary, right?
So what happened?
He was trying to sell his Toyota Tacoma when an interested party stopped by.
The test drive seemed to get off to a good start, and with cash already in hand, the sale looked like a sure thing.

However, things took a sudden turn.
“During the test drive, the guy kept on bringing it up, like, ‘Oh, what’s that smell? Does it smell like burning oil, burning rubber? What’s that smell? Is it coming from the car?'” Anthony recalled.
At the end of the drive, one of the men in the group asked Anthony to pop the hood.
That’s where a bunch of oil was spotted in the engine bay.
He obliged when they asked him to rev the engine a bit more to see if smoke was still coming from the car.
It was at this point that the buyer called attention to the truck’s exhaust pipe, which was leaking oil.
“I think they put oil or something in there,” Anthony said.
The buyers then tried convincing Anthony that oil had made its way into the coolant reservoir.
However, Anthony did some Googling and found that a coolant-oil mix would be coffee colored – this was still pink.

All of this seemed to be the buyers’ way of angling towards an extremely low purchase price.
“I almost took it,” Anthony lamented.
“But I’m so glad that I didn’t because now I’ve just got to get all this oil out of this coolant.
“It’s just more of a headache than anything.”
People have to be vigilant towards scams nowadays
This dirty oil scam is surprisingly common, as many have testified online.
Essentially, a person will pour oil into the coolant reservoir of a vehicle in order to produce smoke during a test drive.
The scammer then uses this to haggle their way into a lower price.
This isn’t the only scam that has been spoken about in recent years.
One Ohio man was swindled by an AI video of Jelly Roll, which told him he’d won a new car.
Another fell for a ‘Corvette scam’ that set him back $30,000.
But not everyone has fallen prey to these scams – one woman in South Carolina swerved one that involved a $100 bill being placed under her windshield wiper.
