2001 Saturn LS1, SC1, SW1

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2001 LS1, SC1, SW1.

The 2001 Saturn LS1, SC1, and SW1 carry a 4.2-quart 5W-30 API oil specification as their engine requirement, while reliability records for the year show only 26 total owner complaints across two recalls, with tires surfacing as the top complaint area. That restrained volume of feedback places the 2001 model year among the more stable entries in the documented reliability history. For researchers, this establishes a comparatively quiet benchmark when assessing the broader Saturn model run.

From the factory this vehicle uses a BCI 75 · 525 CCA battery, OE oil filter 21000872. Note the factory fuel filter and front wiper blades are now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known. Each part links to every other vehicle that shares it, so a part you already stock may fit more of your fleet than you'd expect.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the spark plugs at 150,000 mi; coolant every 100,000 mi. The big-interval services (every 100,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

Owner complaints about the 2001 Saturn LS1, SC1, SW1 top in one area — the tires, 4 of 26 reports (15%), well ahead of the next concern. None of this vehicle's 2 recall campaigns target the tires, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 4 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the tires pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
