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
The simple answer: Piston rings form a seal between the piston and cylinder wall, which prevents pressurized combustion gases from entering the oil sump. They also regulate oil consumption by preventing excessive oil from entering the combustion chamber and burning. Properly functioning rings are vital to maximum engine power and efficiency.
The simple answer: Yes, provided the diesel oil meets the appropriate specifications and viscosity requirements of your engine. For example, if your gas engine calls for a motor oil that meets the API SN specification, you can safely use a diesel oil of the correct viscosity that meets the API SN spec.
Most of us know excessive engine wear eventually leads to costly breakdowns and engine failure. But even if your engine doesn’t fail, wear robs your vehicle of power, performance and that “like-new” feeling you crave when driving.
I was helping my parents move the other day, and it struck me – “Wow, today’s pickups are massive.” Trundling up Highway 53 in northern Wisconsin behind the wheel of my dad’s Ford F-150 felt like navigating a battleship. And many of the trucks on the road dwarf his pickup.
The simple answer: Yes. There is no danger mixing synthetic and conventional motor oil; however, conventional oil will detract from the superior performance of synthetic oil and reduce its benefits.
Motor oil deteriorates and becomes unfit for service due to accumulation of contaminants in the oil and chemical changes (additive depletion and oxidation) in the oil itself.
