A Toyota driver rolling down the freeway with the fuel gauge sitting on empty would normally be a recipe for panic, but not in this case. One Land Cruiser owner recently proved that sometimes the low fuel light isn’t the emergency it appears to be.
Chad Mfive, known online as @Chadbmw, shared a Facebook Reel that’s racked up more than 7.4 million views, showing him cruising along the highway while his fuel gauge hovers near zero. Instead of pulling over or sweating bullets, Chad looks completely unfazed as traffic flies by.
In the video, he casually explains that his Toyota Land Cruiser is basically out of gas, then calmly reaches beneath the steering wheel and presses a button. Almost instantly, the fuel gauge jumps back to full, revealing the trick that has viewers both amazed and nostalgic.
The secret is something you don’t see much anymore: a factory dual-tank setup. Chad later explained that when the main fuel tank runs dry, he simply switches over to the second tank, giving the truck a whole new supply of fuel without ever leaving the driver’s seat.
While his caption jokingly claimed he ran out of gas on the freeway, the Land Cruiser’s built-in backup tank kept him moving. His tongue-in-cheek comment about having an “unlimited supply of fuel” struck a chord with viewers who remember when vehicles were built with features like this.
The comments quickly filled with people reminiscing about older trucks and SUVs that came with dual tanks. Some pointed to classic Ford and Chevy pickups from the ’70s through the ’90s, while others joked that even with two tanks, they’d still somehow find a way to end up stranded.
As clever as the setup is, dual fuel tanks have largely disappeared from modern vehicles. They were once popular because they extended driving range, helped balance weight, and made sense for trucks used for towing. But they also brought downsides, including complicated refueling, valve failures, and safety concerns.
One of the most notorious examples was Chevrolet’s old side-saddle tank design, which placed fuel tanks outside the frame rails. That layout proved dangerously vulnerable in crashes, with reports linking it to more than 2,000 fire-related fatalities between 1973 and 2009.
As fuel efficiency improved and safety standards tightened in the 1990s, automakers quietly phased out dual-tank systems. Today, Chad’s Land Cruiser serves as a rolling reminder of a time when running out of gas didn’t always mean pulling over—sometimes it just meant flipping a switch.
