The gasoline or diesel that goes in the fuel tank is by no means the only petroleum used in cars. Oil is also used as a lubricant to keep all the metal parts sliding smoothly over one another. That lubricating oil needs to be changed periodically as it gets contaminated. Unfortunately a lot of people who change their own oil don't dispose of it properly, leading to contaminated soil and ground water. However, Green Earth Technologies has developed a new oil that isn't made from crude and even biodegrades very quickly. The motor oil is made from saturated fat from beef. After it's done lubricating your engine, you mix it with G-DISPOSOIL which breaks it down almost immediately in to something that can be poured onto the ground. The liquid can be consumed by bacteria in the soil which decomposes 90 percent of the oil within nine days. If anyone tries out G-Oil in their own engines, let us know how it worked out for you.

Oftentimes, when the subject of oil appears on the internet, a raging debate ensues regarding which brand offers the highest quality or whether or not synthetic is superior to straight dino-oil. We're not touching that one today, but we would like to remind our readers of the importance of recycling your used motor oil. Matt Hale, Director of EPA's Office of Solid Waste, says, "Recycling used motor oil conserves energy, reduces greenhouse gas emissions, and prevents the possible contamination of our nation's drinking water supplies." How bad could a little used motor oil be on our water supplies? We'll let Castrol explain: 'one oil change -- improperly disposed and not recycled -- can contaminate one million gallons of fresh water, which is a year's supply for 50 people.' With that information firmly in mind, Castrol has teamed up with Earth911.com to educate people on oil recycling.

We've pasted a press release regarding the subject after the break. For tips on oil recycling and to find your nearest oil collection center, check out Castol's site here and Earth911.com here.
