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.
Can I stain pressure treated lumber? Yes, you can stain pressure-treated lumber with the one exception, that the decking has completely dried out and has been clean of any and all dirt. How long should I wait to stain pressure-treated lumber and why do I have to wait? The process begins at the lumber yard factories and treatment plants. The pressure-treated lumber goes through a process of using a water-based solution that carries the treatment of chemicals into the fibers of the wood while under pressure; this leaves the wood wet.
