Jeep Wrangler: TECHNICAL SPECIFICATIONS / FUEL REQUIREMENTS — GASOLINE ENGINE
While operating on gasoline with the required
octane number, hearing a light knocking sound
from the engine is not a cause for concern.

knocking sound, see a dealer immediately. Use

recommended octane can cause engine failure

experience these symptoms, try another brand
of gasoline before considering service for the
vehicle.

deep wall socket...
