For those who are looking for a used car in New York as their first vehicle purchase, they may want to heed the advice from a national magazine with a list of debunked summertime myths.

Before vacationers hit the open road, Popular Mechanics has answered some common questions about car maintenance in the summer, especially for used cars.

While a new vehicle may be able to function on thinner engine oil, such as 5W-5, it’s important for used car buyers that their vehicles will be different.

Most used cars require thicker oil in the summer with many car manufacturers listing 10W-30 as good for driving in higher temperatures.

There are some older used cars that may require 10W-40, though the magazine suggested people consult the vehicle’s user manual before using that kind of oil.

In terms of coolant, the mixture is the same whether or not a person has a new or used car: it’s 50 percent coolant and 50 percent water.

Finally, and this may be of importance to first-time drivers, Popular Mechanics reminds summer vacationers that if they find their engine overheating, it’s time to turn off the air conditioner and turn on the heat.
