Contrary to popular belief, there are still some vehicles out there that use mineral engine oil in their cars. For the most part, this is due to a myth going around that if a car starts out with mineral engine oil, it cannot use synthetic engine oil.
What you need to know is that this is nothing but a myth. Even older models of cars are perfectly capable of making the switch to synthetic engine oil. The real question is if you should make the switch or not. If you’re on the fence about it, here are a few reasons why making the switch makes sense:
Save on Costs
You’re probably aware of the “every 3,000 miles” rule for changing oil. Synthetic oils don’t follow that rule. With a mixture of performance-enhancing additives, synthetic oil degrades much slower than mineral oil, leading to less frequent changes.
Preserve Engine Life
A byproduct of mineral oils is wax. Needless to say, wax buildup in your engine isn’t something you should be happy about. Wax is absent in synthetic oils, helping your engine run better and last longer.
Better Year-round Performance
Very cold and very warm temperatures cause changes to the viscosity of mineral oil. If it runs too thin, oil is unable to properly lubricate your engine. This is a common problem with mineral oil. If you live in an area with a wide range of weather patterns, making the switch to synthetic oil makes sense.
