The 10W30 designation on engine oil means that the viscosity of the oil is rated at 10W when an engine is cold, and 30 when the engine is hot. This is different than an oil labelled 5W30, which has a thinner viscosity when the engine is cold at 5W....
Prior to 1985, the standard motor oil was 10W-40; however, today it represents just 2% of total sales. The No.1 motor oil today is 5W-30, which accounts for 56% of the light-duty market. Since the 1980s, the viscosity of motor oil has become gradually lower primarily to improve fue...
The second number indicates how the oil will perform in very hot temperatures---the goal is to keep the oil from getting too thin because thicker oil performs better in heat. These numbers range in multiples of 10 from 10 to 60, with 60 being the thickest. Oil that is graded 5W-60 is...
Your car may be more difficult to start if you use some of the thicker oils, including 10W-30 full synthetic and 5W-20 full synthetic. This is particularly valid in colder climates. Additionally, they can raise your overall oil pressure and decrease the flow around the engine. More pressure...
At this time, the thin spots are significantly hotter than the thicker parts of the filament and are evaporating rather rapidly. As described earlier, this process is accelerating. If the thin spots are protected from surges, the life of the bulb would be extended by only a few percent. ...
The first test I wanted to do was a quick 5% to 20% test as this is where many of these fast charge solutions shine. In my comparison, I used a default Apple 5W charger, a Google Pixelbook USB-PD (45W) charger with OEM cable, the Dash Charge from my OnePlus 6, and the...
