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 is great for wet locations as it is also resistant to rotting. However, decks made of this type of wood generally need to be re-sealed every other year, which can add to its overall costs. The average price per square foot of this material is $2.35.
