Toyota Motor Sales (TMS) has announced a new so-called “customer satisfaction programme” that extends to 2002 models and eight years the coverage of a “Special Policy Adjustment” (SPA) announced in mid-February. The February SPA, valid for only a year, covered "certain 1997-2001 model-year vehicles with four- and six- cylinder engines" affected by oil sludge (or “gelling” as Toyota calls it), provided owners could produce "reasonable evidence of regular engine maintenance".
