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.
This makes the wood less likely to rot as well as unappealing to insects and vermin, which is ideal for outside wood projects. However, this process has both pros and cons, as some chemicals used can be toxic. Warning: Pressure-treated wood can be toxic to humans and pets.
