Amsoil is better for the environment. Not only do we have non-toxic coolant, but also a longer lasting oil equates to less frequent oil changes per year. This results in less dumping of oil. Can you imagine if millions of people dumped less oil per year? Let's crunch some numbers. A vehicle that uses 4 quarts and lasts 1 year, that is 4,000,000 quarts that will be disposed across a sample of a million vehicles. Now if those same vehicles are changing the oil 4 times a year due to regular oil that lasts much less, that is 16 quarts disposed of a year or 16,000,000 quarts in a sample of 1 million vehicles. There are way more vehicles than this on the road. These numbers show way less oil disposed of and much less oil consumption.
