Some people remain attached to the 3,000-mile oil change and have a hard time trusting the recommendations in the ownerâs manual. If youâre one of those skeptics, you can send your engine oil out to be analyzed.
Picnic tables made of pressure-treated wood have become common, and are fine to use for the purpose they were intended... to serve food on (or play cards on), not to prepare food on! They should be coated as needed with an oil-based wood preservative (not paint or opaque stain) to seal in the chemical preservative.
When wood is in contact with the ground or moisture for any period of time, these organisms attack the wood. Untreated wood like pine will only last a year or two if it is touching moist ground. Pressure-treated lumber is wood that has been immersed in a liquid preservative and placed in a pressure chamber.The chamber forces the chemical into the wood fibers.he chemicals in treated wood are generally not good for humans. This is why you see warnings advising you to wear gloves, avoid breathing the sawdust, and refrain from burning treated wood. Keeping small children away from treated wood is also a good idea.
