#10 -- Well, thanks for telling us HOW to check our credit for free.

#3 BS. Oil breaks down in two ways. Due to heat and becomes sludge that will stick to the insides of your engine. Due to gas seeping by the rings and stops the oil from lubricating as well. That is why there is a date also on the sticker from the oil change place.

#9 True unless your car is made to run on premium gas.

If it's done correctly, the cost of anything isn't based on how much it costs to produce it. Only a stupid communist / socialist would think that the cost of something needs to be based on the cost to produce it. This is why socialists always complain that the other guy has more than he does and instead of working to accomplish something, he opts to take away what others have. Cost should always be based on value, or what other people are willing to pay you for it. All of you Izi'ers complain about "'murica" but still use and enjoy all of the benefits provided by the capitalism they so detest... How about putting some effort into your own life...
