Suzuki Forenza Motor Oil Flush
I flush the engine and afterwards change the oil and filter on a 2004 Suzuki Forenza. The flushing agent I use is Motor Medic; Mobile 1 for the oil afterwards, and a FRAM filter. I would not bother flushing your oil, unless there's a sludge problem due to irregular oil changes. In that case, a thorough flush is well advised. Or if you have an old car and it's never been flushed before. Here's a link to the Suzuki Forenza owner's manual. The manual is for the 2007 model, but it applies equally to all years that have the 2.0 liter dual overhead cam engines (VIN code Z), in regard to maximum motor oil capacity (4.2 qts) and type (5W30): http://www.autodealertools.com/quickQuote/manuals/2007/Forenza.pdf
