As engine operating conditions grow more severe, so do the demands placed on your motor oil. New engine hardware such as turbochargers, direct injection and variable valve timing (VVT) place increased stress on your engine oil.
Analysis of used oil provides insights into the health of the oil and filters as well as the equipment. While the benefits of analysis are clear, making sense of the report you receive can be a challenge. Unpacking the elements of a typical report is a great way to improve clarity. Each oil analysis lab has a slightly different report layout and you should check with your analysis lab if you have
Changing your own oil may not always be enjoyable, but it is fulfilling and worthwhile. DIY projects such as changing your own oil promote self-reliance and extra peace of mind that the job was well done.
Sludge. It’s a disgusting phenomenon. Even the word sounds gross, like the thing it’s describing.
It’s been a long, long time since motor oil was “just oil.” In the 1930s, someone decided to begin putting wax modifiers in the oil to address the problem of wax residue after the refining process. Thus was born the motor oil additive market. Today, motor oils, whether petroleum or synthetic, contain a variety of
Everyone who owns a vehicle knows you need to regularly check the oil level. (Note: If you do not know this, you’d better go check your oil.) A certain amount of oil loss is normal due to motor oil volatility – that is, boil-off due to the high-heat conditions inside an engine. I once attended
Remember the Saturday-afternoon infomercials for the latest “revolutionary” motor oil additive? I enjoyed one in which a group of mechanics added a bottle of additive to an engine they’d suspended from a hoist. Then they drained the oil, started the engine and lowered it into a tank of water. There it sat, gurgling away and
Yes. Test data repeatedly shows that synthetic motor oil outperforms conventional oil, delivering… Improved wear protection Better extreme-temperature performance Maximum fuel economy Longer service intervals Some of you are undoubtedly thinking, “But I’ve used conventional oil for years, and my engine runs fine.” It’s important to note I didn’t say all conventional oil is junk
Although gas is hovering around only $2.00 per gallon these days, increasing fuel economy is still a top priority for most automakers, due in large part to more strict corporate average fuel economy (CAFE) requirements on the horizon. One strategy automakers are using is widespread use of synthetic lubricants. How do synthetics increase fuel economy
Here’s the straight story on viscosity grade. The “W” number in, for example, a 15W-50 motor oil outlines the viscosity requirements of the oil when it is cold. This means that a 15W-rated oil has to meet certain criteria at cold temperatures. Taking our 50-weight example, a 15W-rated oil will flow more freely than a 20W-rated
