When you take a look at the Hyundai cars near Somerville this time of year, one thing is common to all of them: they’re cold. Winter can be hard on a car, and you do everything you can to try to make sure that your car runs fine through the winter.
It used to be that one of the problems you needed to worry about during winter was that your fuel would gel. Prior to the 1970s, valve guides were merely small holes that were drilled into the iron head of a cylinder. These guides needed some extra help during the winter to maintain their lubrication. Since then , these guides have been made of bronze, and are more resistant to wear.
Further complicating this question is the fact that these fuel additives are still on the shelves. In addition, diesel engines can benefit from an antigelling additive. However, most vehicles you’ll find on the road today have no need for an antigelling fuel additive. Adding one doesn’t hurt the vehicle, but it doesn’t benefit in any way, either.
