For these reasons, healthy levels of magnesium have been linked to deep, undisturbed sleep. Consequently, low levels of magnesium can contribute to frequent nighttime wakings. Magnesium deficiency has been linked to several insomnia-inducing conditions, including restless leg syndrome (RLS) and night terrors.
Scuffing is another condition that can damage pistons. Scuffing is often the result of overheating, but loss of lubrication, detonation and preignition can also be contributing factors. When an engine runs hot, the pistons swell. This reduces the clearance between the piston and cylinder walls. The cylinder bore can also distort adding to the problem.
The change in the gear ratio from taller tires that reduces engine rpm at a given speed also causes the throttle plate to be open farther. That reduces the pumping losses on a gas engine caused by trying to suck in air at part throttle. That is partly why diesel engines get good MPG's, no throttle plate to restrict.
