A Tow Providers Instinct is Always to Help Others First Chad, a tow truck operator, was in a crash with another driver but instead of tending to his own injuries, he rushed to the injured to help. Reacting without Hesitation to Save a Life Saleem, a tow truck operator, and one of his staff rushed out to help someone who had been in a serious crash in front of their shop.

Today's engine oils have evolved into brilliantly engineered blends of refined petroleum and sophisticated additives that enable them to retain their protective properties through all those months and miles and inhospitable conditions. Some are suitable for light usage through reasonable periods of time, while others are better for harder and longer-term use.
Today's highest-performing, longest-lasting engine oils are synthetics, which means they are typically engineered and manufactured from chemically modified petroleum components and some other materials.
Synthetics can provide better startup performance and flow at temperatures down to Fahrenheit, then endure extremely high temperatures without oxidizing, thickening, or turning black. With automakers increasingly using thinner, ultra-low-viscosity thickness oils to reduce running friction for better fuel efficiency, synthetics can be formulated to much lower viscosities while retaining their protective and lubricating properties.
They are typically two to three times more expensive than regular oils, but they are cleaner and more robust, have superior chemical and mechanical properties, especially in extreme temperature ranges, and can retain those properties longer between changes.
There's a lot of nonsense floating around about when to change your synthetic oil. If your vehicle runs synthetics—and most do these days—the best place to find the correct oil-change interval is the owner's manual. Mobile Newsletter chat avatar. Mobile Newsletter chat subscribe. Under the Hood. Vehicle Maintenance. Do you really need to have your car's oil changed every 3, miles? Experts say not necessarily.
Every 1, miles 1, kilometers or every six months Every 3, miles 4, kilometers Every 5, to 7, miles 8, to 12, kilometers Every 10, to 15, miles or every six months 16, to 24, kilometers. If you're not making long trips at high, steady speeds like you would on a highway then your engine isn't getting hot enough to boil off condensation that accumulates in the system.
That can cause oil to break down faster. Most of the wear and tear on your car's engine occurs when you're starting your car, and if you aren't driving very far, most of your driving is of the type that is very hard on your engine. More frequent oil changes will help minimize the damage. Now That's Interesting.
If you drive your car infrequently — as in much less than the mileage of your recommended service interval — you should still change your oil twice a year since the oil degrades over time. Can you go 10, miles with synthetic oil?
Sure you can. In fact, you can even go over 10, miles with synthetic oil. Is full synthetic oil worth it? Synthetic oil definitely can be worth it. Some synthetic motor oils, like Amsoil, NEO and Red Line, to name a few, are created specifically to last 25, miles or one year before needing a change.
While neither conventional nor synthetic motor oils are good for the environment if disposed of improperly or spilled , most environmentalists would opt for the latter since it lasts three or more times longer and thus reduces waste or energy use if recycled. Researchers have been experimenting with producing greener motor oils—one pilot project out of Purdue University has produced high-quality, carbon-neutral motor oil from canola crops—but consumers should not expect to see such products on store or garage shelves anytime soon, as the costs of production are high and the availability of cropland is limited.
But the very existence of such alternatives—no doubt more are in the offing—bodes well for the future as oil becomes more scarce and expensive. Box , Westport, CT ; submit it at: www. Read past columns at: www.
