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.
Makaco Unanimous asks on our Facebook page about break in oil, with attention paid to powersports engines. First, thanks for the question, Makaco Unanimous. Second, I think I found my name for next season’s fantasy football team. Let’s get to it. Maintaining an engine is a constant fight against wear.
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.
Here is the short answer: Yes, brake fluid can go bad. Brake fluid absorbs moisture, which reduces its performance. For that reason, it’s best practice to change brake fluid every two years. The AAA published a study, stating that brake fluid is the most often missed maintenance item by drivers.
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.
Thanks to Hugh Ashburn for asking this question on our Facebook page. I assume when you say “older,” you mean a classic car or hot rod with a flat-tappet camshaft. Compared to their roller-cam counterparts, flat-tappet cams undergo sliding contact rather than rolling contact.
Most of us have a car battery story we could resurrect if asked. I have a few, but the most memorable was in 1986 when my son was born. On our seventh anniversary, my wife and I had dined at the now-forgotten Lemon Drop Restaurant on London Road in Duluth, Minn.
Early automobile engines didn’t use oil filters, or air filters for that matter. For this reason frequent oil changes were a must. Motor oil quality wasn’t really that important in those days, anyway. It was the discarded by-product of processes designed to create other products from crude oil, like fuel, benzene and other petrochemicals.
I’ll be honest – I can’t drop a new set of gears in a rear differential or install a performance cam. I have lofty dreams of owning a red Jeep Wrangler, but real wrench turning might lie beyond my particular skill set. Luckily, I work among a legion of gearheads. Our generous car gurus offered
