What's the 2002 Chevy TrailBlazer 4.2 Oil capacity?

Sometimes the correlation between engine size and oil capacity can be a bit misleading. While the 2002 Chevy TrailBlazer has A4.2L, V-6 under the hood, it requireS7 quarts of oil with filter. This is a large amount for an engine that is powerful but not exactly heavy duty. An SUV with this many years on it will need a little extra care than a newer one would. Parts that are original but have high mileage on them require even more vigilance. Check Your fluid levels frequently. Add more when needed but note any large losses. This could signal a soon-to-be malfunctioning part. Use synthetic oil to keep nasty chemicals out that are naturally found in conventional petroleum products. Doing all of this should help keep Your Trailblazer churning along and maybe even extend the life of the engine further.
