Understand the Labels
These are the labels you'll find on every container of reputable motor oil. The API donut on the right tells you if the oil meets the current SL service rating (C for diesel engines). It also provides the SAE (Society of Automotive Engineers) viscosity number and tells you if the oil has passed the Energy Conserving test. The starburst symbol on the left indicates that the oil has passed the tests listed for SL service.
Is oil really the lifeblood of an engine? That's a long-popular analogy, but it's really not an accurate description. Blood carries nutrients to cells, but it's air that carries fuel—the "nutrition"—for an engine. However, without oil to lubricate and cool moving parts, keep them clean and help to seal the pistons in the cylinders, the engine would run for only a matter of seconds, then sieze. So, yes, oil is important.
Oil is so important that we want no less than the best the engine can get—for a good low price, of course. Now, what if you could custom-blend the oil so it had exactly the characteristics you believe that your vehicle needs for the type of driving you do?
Sounds pretty neat, and we were given the opportunity to do just that at the Valvoline lab in Lexington, Ky. When we were finished, we had an oil we thought would be just right for upcoming summer weather in short-trip driving around the New York City area.
That was our one shot at playing lubricant scientist, but the experience produced only enough oil for a top-up. So at the next oil change, we'll have to pick from an off-the-shelf assortment--like everyone else. But we think we'll do a better job of selection now, thanks to a short course in engine oil blending from Valvoline Technical Director Thomas Smith. Here's what we learned.
