Motor oil turns black during use for a couple reasons: 1) Heat cycles During your drive to work in the morning, your engine reaches normal operating temperature (typically 195ºF-220ºF), heating the motor oil. Then the oil cools while your car sits in the parking lot.
One thing the Internet has done is create a lot more “experts.” In the old days when you had a car maintenance question, you knew whom to ask – ‘ol Mike up the street with grease under his fingernails and a rag in his back pocket.
Scott D. Galbreath asks via our Facebook page about the pros and cons of synthetic blend motor oils. Thanks for the question, Scott. Making sense of motor oil can be confusing and frustrating. Choosing among full synthetics, synthetic blends, semi-conventional, conventional, high-mileage full synthetics and synthetic blends is just the beginning.
Frank wants to know, via our Facebook page, the pros and cons of using mineral oil versus synthetic oil in a methanol-fueled engine. Thanks for the question, Frank.
Turbocharged, gasoline-direct-injection (T-GDI) engines have been the topic of many AMSOIL blog posts and other publications the last few months, and for good reason. In recent years these technologies have taken the automotive industry by storm.
I’m probably from the last generation of people who largely changed their own oil. As the pace of life has increased and engine technology has grown more complicated, most people now pay a professional to take care of their auto-maintenance needs.
Unlike food and drug companies, which must disclose the ingredients in their products, lubricant manufactures aren’t held to the same mandate, which can cause confusion if you’re shopping for synthetic motor oil. Store shelves are lined with oils described as “full synthetic,” “semi-synthetic,” “synthetic” and even “100% synthetic.”
The Internet is abuzz over the latest Blackstone Labs newsletter. OK, “abuzz” may be a stretch. But the newsletter certainly has sent the motor oil geeks among us into a tizzy. The distinguished oil analysis laboratory sought to answer the age-old question: Does it really matter which brand of motor oil your use?
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.
