The average carf bill has increased by $4,800 over the past year, according to a survey of over 1,200 car dealers in the United States.
The average bill for an oil change alone in the U.S. jumped by nearly $5,400 in 2016.
The survey found that in 2017, the average bill went up $2,000, or 10.5 percent.
Carf, a substance found in some car batteries, is the most common cancer cause among consumers, according the Centers for Disease Control and Prevention.
The CDC says more than 60 percent of Americans get cancer from the substance.
The researchers who conducted the survey also found that the average amount of money a consumer spent on carf increased by 5.3 percent in 2017 compared to 2016.
Car dealers say that while there is no denying that carf is expensive, the price of the drug can be a barrier to consumers seeking the best care.
They say the high price of carf has made it harder for consumers to find the best treatment, even though it is widely available.
CarF can cause serious side effects such as nausea, vomiting, blood in the urine and even a death.
The American Cancer Society estimates that the drug causes about 4,000 deaths per year.
In the U of A study, researchers at the University of British Columbia and the University in Queensland found that carfill can cause cancers of the esophagus, stomach, lungs, pancreas, liver and kidney.
Carfill is most commonly used in patients with cancer of the pancreases, and the researchers say carfill also has the potential to cause pancreatic cancer.
The drugs were developed by pharmaceutical company Pfizer and the American Cancer Research Institute.
The drug companies say that carfilled products are safe and that they do not have an adverse effect on health.
But in a statement to Recode, Pfizer said, “We have taken extensive safety precautions to protect our patients and to ensure the safety of our medicines.”
It also said that carfound products are “used widely throughout the world” and are available for prescription and over-the-counter use.
Pfizer says it is committed to ensuring that Pfizer products are used safely and responsibly.
