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.
Pressure-treated wood has been around for nearly 70 years, yet most of us still know very little about this popular outdoor building material. To start, pressure-treated wood is softwood lumber, typically southern yellow pine, that's been chemically treated to resist rot, decay and termites. The boards are rolled into giant pressurized tanks where chemical preservatives are forced deep into the wood's fibers.
