;You DON'T want to drink your oil? Well, no one else does either.Needing to change your oil less often doesn't just help your wallet, it means fewer bottles and packaging that end up in our landfills, less waste oil which too often ends up in our stormdrains, and then our waterways and drinking water. The choices you make have an impact.No one is suggesting that you alter your lifestyle; life is meant to be lived. This is about how best to maintain the equipment you rely on. When you can spend less money (see cost calculator chart above), use less of your time and effort, and be environmentally-friendly in the process, why wouldn't you?
