Why? From the manual:

Tires need the correct amount of air pressure to operate
effectively.
Notice: Do not let anyone tell you that
under-inflation or over-inflation is all right. It is not.
If your tires do not have enough air (under-inflation),
you can get the following:
• Too much flexing
• Too much heat
• Tire overloading
• Premature or irregular wear
• Poor handling
• Reduced fuel economy
If your tires have too much air (over-inflation),
you can get the following:
• Unusual wear
• Poor handling
• Rough ride
• Needless damage from road hazards

Change your own oil...there is no easier engine in the world to change your own oil than on the Ecotec

Yep, chances of being asked to produce oil receipts in the event of an internal engine problem are very small. If you throw a rod through the pan in warranty you will IAL get it fixed "no questions asked" unless you leave your drag strip ET's on the seat
