If you’ve had to get your engine repaired, you know the worry about a rebuilt engine vs. a new engine. There are so many pros and cons, especially when you compare the cost for a brand new engine can reach into the thousands. But a rebuilt engine, while less expensive, can also be a concern. Will it last? What does that really mean?
A rebuilt engine means that at some point, something inside the engine failed. For the non-technical out there, just imagine that there are several different types of components that make up an engine like rings, gaskets, pistons, etc. If any one item or multiple items fail, then the engine must be taken apart and those components replaced. Then the entire engine must be put back together. Rebuilding an engine is typically referred to as one of the most important, invasive and expensive repairs you can make to a car. After all, it is the heartbeat of ...[more]
At one time, there were only a couple of choices for motor oil. Today, that is no longer the case, and hasn't been for quite some time. Here's a quick breakdown of what you need to consider when it's time for an oil change:
- Viscosity: Viscosity is how thick your oil is, and how it retains its pour properties at various temperatures. In this respect, synthetic oil is far superior. Conventional oils will thicken in cold weather and thin out when very hot, while the viscosity of synthetic is much more uniform. Check your owner's manual -- many newer models require a thinner, lower-viscosity oil, which also helps the engine run more efficiently. Viscosity is expressed as a numerical value -- the lower the number, the thinner the oil. Many are designed to work a ...[more]
Automotive technology has come a long way since the mid-20th century, and so has motor oil. A 1940s-era car didn’t feature an oil pump or oil filter. Instead, they relied on dippers on the crankshaft’s counterweights, which would then sling oil to coat crucial moving parts. Motor oils in those days weren’t designed with detergents and other additives to help keep the engine clean; even with frequent oil change intervals, many cars would be in need of an engine overhaul by the time they reached 80,000 miles.
Today’s motor oil formulations incorporate additives to suspend contaminants in the oil so they can easily be trapped by the oil filter. Here are a few other facts about motor oil you may not have known:
