No. Switching brands is not harmful to your engine as long as you choose an oil marked with the API donut of the same level, e.g., API SN. … You may give up enhanced performance if you switch from synthetic or high mileage to conventional oil. MYTH: When motor oil becomes dark, that means it’s time to change it.
Is more expensive oil better for your car? Synthetic oil is more expensive than conventional oil but offers superior protection for your car’s engine. Synthetic oil provides more effective protection for your car, may even prolong the life of your engine and would cost the average driver just $65 more each year. …

How to check if engine coolant is good?
When the engine reaches operating temperature, insert the positive probe directly into the coolant. Rev the engine to 2,000 rpm and place the negative probe on the negative battery terminal. If the digital meter reads . 4 volts or less, your coolant is in good condition.
How much thrust can a jet engine produce?
The thrust of a typical jetliner engine went from 5,000 lbf (22,000 N) (de Havilland Ghost turbojet) in the 1950s to 115,000 lbf (510,000 N) (General Electric GE90 turbofan) in the 1990s, and their reliability went from 40 in-flight shutdowns per 100,000 engine flight hours to less than 1 per 100,000 in the late 1990s.
How are tractor engine hours measured?
They will read hours as if the engine was run at 540 rpm PTO speed. Example, if mine was run at 2500 rpm(540pto speed) one hour of meter time equals one hour real time, if engine rpm is say at 1250 rpm for one hour, that equals . 5 hours meter time.
Is robotics engineering a good career?

The mechanical engineer has been called the general practitioner and the jack-of-all trades among engineering professions. This is because the profession requires education and skills that span a broad range of technical, social, environmental, and economic problems.
How do they make jet engines?
The fan blade is made by shaping molten titanium in a hot press. When removed, each blade skin is welded to a mate, and the hollow cavity in the center is filled with a titanium honeycomb. The turbine disc is made by powder metallurgy, while the compressor blades and the combustion chamber are both made by casting.
How to know when your engine oil is bad?
Dark and Dirty Oil — Clean oil is an amber color, but after a while, it darkens and gets dirty from the particles it collects from the engine. If you can see the stick through the oil, it is fine. However, if it’s thick and dark, it’s time for an oil change.
