Plastic fuel tanks are a common alternative to standard metal tanks, and they are increasingly being used in cars. Plastic tanks are made of impact-resistant composite material, making them durable and able to withstand mechanical shocks and aggressive chemicals. They also have the added benefit of not rusting.

Lexus

Lexus car owners have discussed the possibility of their Lexus models having plastic gas tanks. One owner of three Lexus cars—a 2005 IS300, 2008 RX350, and 2012 RX350—was unsure whether their cars had plastic or stainless steel gas tanks and wanted to know if anyone had experienced their tanks rusting from the inside. Some responses indicate that the tanks are probably plastic, except for the IS model. Another owner of a 2005 Lexus IS300 and a 2012 Lexus RX350 also expressed concerns about internal rusting due to the cars sitting for a long time without being driven.

Plastic fuel tanks are available as replacements for standard metal tanks installed on Lexus cars. These plastic tanks are made of impact-resistant modern composite material based on polyester resins. They are more durable than standard metal tanks and can better withstand mechanical shocks and aggressive chemicals. The tank fasteners correspond to the factory specifications, allowing for a quick and easy replacement without the need for body modifications.

Toyota

Plastic fuel tanks are also available for Toyota cars. These tanks are made of impact-resistant composite material and are designed to fit specific Toyota brands. They feature special ribs inside that increase mechanical strength and reduce fuel movement during acceleration and braking. Like the Lexus plastic tanks, these tanks for Toyota are also quick and easy to replace.

Toyota car owners have also discussed the possibility of their cars having plastic gas tanks. One owner of three Toyota cars—a 2005 IS300, 2008 RX350, and 2012 RX350—was unsure if Toyota had switched to plastic gas tanks for newer models or if they still used metal. They were concerned about internal rusting due to the cars not being driven for a long time.

In summary, while it is not definitively confirmed that Lexus and Toyota cars have plastic gas tanks as original equipment, plastic tanks are available as replacement options for these car brands. These plastic tanks offer advantages over standard metal tanks in terms of durability, resistance to rusting, and ease of replacement.

Plastic tanks for Volvo cars

Volvo cars have been associated with plastic fuel tanks, particularly the 200-series and the P2 models. Some Volvo owners have expressed interest in purchasing plastic fuel tanks, especially those who live in colder regions with salted roads, as the salt can cause rock chips on the gas tank that turn into rust spots over time.

One owner of a 2005 V70 Volvo, for instance, mentioned that their car had a steel fuel tank, while another owner of a 2002 S60 2.4T Volvo was unsure if their car's fuel tank was made of steel or plastic. This uncertainty could be due to the fact that most modern car manufacturers use plastic for fuel tanks, and Volvo has likely transitioned to plastic tanks for newer models.

Volvo, in collaboration with MEGA Corp, also manufactures articulated truck tanks, which are water tanks for Volvo articulated prime movers. These tanks are made of carbon steel pipe, with the option to upgrade to stainless steel spray bars and spray heads. MEGA Corp provides detailed technical manuals for installation, operation, maintenance, inspection, and replacement parts for these water tanks.

While there is some ambiguity regarding the fuel tank composition of certain Volvo models, it appears that Volvo, like many other car manufacturers, has likely adopted plastic fuel tanks for at least some of their newer vehicles.

Plastic tanks vs. metal tanks

The choice between plastic and metal gas tanks in cars has been a topic of discussion for car manufacturers and enthusiasts alike. While plastic tanks have gained popularity, there are pros and cons to both options, and it is essential to consider various factors when deciding which type of tank to choose.

Plastic fuel tanks, made from high-density polyethylene (HDPE), offer several advantages. They are about 30% lighter than metal tanks, which can contribute to better fuel efficiency. Plastic tanks are also more flexible and can spring back into shape after minor impacts, reducing the likelihood of ruptures in crashes. The absence of seams in plastic tanks further enhances their crash safety by decreasing the risk of bursting at the seams. Additionally, plastic tanks do not generate sparks, which can be a safety concern with metal tanks.

However, plastic tanks also have some drawbacks. The molding process for plastic fuel tanks results in a significant amount of industrial waste, approximately 30% of the plastic material. Sorting and recycling different types of plastics can be challenging and costly. In contrast, steel is a more established and cost-effective material, with well-developed recovery and recycling infrastructure. Steel tanks have lower manufacturing costs, especially with OEMs' investments in stamping, welding, and assembly equipment for metal tanks.

Another safety concern with plastic tanks is their behaviour in fires. While plastic tanks act as better insulators, slowing down the heating of fuel in an under-car fire, they will eventually melt, leading to a potential two-gigajoule bunsen burner scenario. On the other hand, steel tanks tend to crumple and burst at the seams when absorbing impact energy, causing a sudden decrease in volume and the ejection of fuel under pressure.

Ultimately, both plastic and metal tanks have their strengths and weaknesses. Plastic tanks offer design freedom, flexibility, and improved crash safety, while metal tanks benefit from cost-effectiveness, established recycling infrastructure, and better resistance to fires. The choice between the two depends on specific requirements, environmental considerations, and safety regulations.

When it comes to popular car brands, Lexus and Toyota have been questioned about their choice of fuel tank material, with some older models possibly still using metal tanks. However, it is unclear if they have transitioned to plastic tanks for their newer models.
