What is the science behind lie detector tests? How do they work?
The supposed science behind polygraph tests is flawed, even proponents say it's only 90% accurate, (critics say it's far less at 70% or lower) so, at a minimum, for every 10 people that are tested 1 of them either gets accused of something they didn't do, or gets away with doing something. (or 3 out of 10 if you take a critic's side) And when it's done by Police, they are legally allowed to lie to you about your results!

Longer lasting engine maintenance
Your engine will last a lot longer as far as the main engine components if you 1)change your engine oil at vehicle recommended mfg intervals.TIP: if you live in hot climates you should change your oil more often and at less miles .2500 to 3000 ml. every 3 months because the climate the hot temperatures break down oil viscosity at a higher rate thus needed more frequent oil changes for the best engine engine lasting performance.2) always use the recommended weight example (5/30w)TIP: Also for best results the recommended rating of the oil for example on the back of the oil bottle is a rating 2 or 3 letters in a circle .Older vehicles use a different rating than newer vehicles and some times they are not interchangeable this information should be available at your local parts store.3)TIP;: Always use the recommended (brand) oil filter.With the way cars are now especially ones with overhead cams and chains ,aftermarket filters might not supply the same pressure aspects of the original oil filter, So as far to have less or more pressure than that is needed to maintain these components correctly with the correct pressure.
Thanks hope this helps
