When you have an older vehicle, it’s definitely important to change the oil regularly — every 3,000 miles or every three months, depending on which deadline comes first. Many mechanics recommend synthetic oil for older vehicles. There are advantages and disadvantages with both synthetic and conventional options. One of the disadvantages to synthetic oil is the price; however, when you find oil change coupons through the internet, local newspapers, or local mechanic shops, price can become less of a disadvantage.
Less Maintenance Required
Originally the automotive industry predicted 25,000 miles between synthetic oil changes, but this number proved to be much too large. Now it’s recommended that you change it every 7,500 miles, which is over two times longer than non-synthetic. It can go longer because it’s slower to decompose, less likely to be contaminated, and less likely to evaporate over time.
Because synthetic oil is composed in a controlled environment, it contains fewer contaminants than natural oil that’s pumped from the ground. The many impurities in natural oil can buildup in the engine and contribute to engine wear and tear. In addition to being cleaner, the synthetic option remains very stable in changing weather conditions. And if you can find some oil change coupons to use, the higher quality is definitely worth the extra expense.
Better Lubrication Throughout the Entire Engine
Synthetic oil continues to flow efficiently through the entire engine, even when the weather is cold. So, it’s definitely beneficial for those cars that are often driven in cold environments. Likewise, it remains stable at high temperatures, which makes it perfect for use in high-performance engines.
Natural oil must be drilled from the ground, sapping the earth of natural resources, while synthetic can be manufactured using fewer of those resources. Additionally, the amount of natural oil that needs to be exposed is much more since it needs to be changed every three months. Man-made varieties need to be changed less – every 7,500 miles – and put less strain on the recycling system.
Not Recommended for New Vehicles
Mechanics recommend that new vehicles be “broken in” using natural oil because it provides sufficient friction for a new engine. A new car should make it to at least 1,500 miles on natural oil before switching to an alternative.
Currently synthetic oil costs a lot more than natural oil. Unless you have oil change coupons, a job using synthetic oil will cost around $60, where as a normal one costs as little as $20 and no more than $30. However, with the advantage of more than double the miles between changes, the extra cost usually balances out. Also consider that the price will be dropping as the industry grows, whereas the price for traditional oil will probably continue to rise.
So, if you own an older car and can save money with oil change coupons, it’s definitely worth it to opt for the higher quality options.
