1998 Toyota Tacoma — V6

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1998 Tacoma V6.

Body TRUCKEngine V6Transmission Automatic 4-spd

The 1998 Toyota Tacoma V6 is a truck powered by a V6 engine and paired with an automatic four-speed transmission, carrying EPA fuel-economy ratings of 17 city, 22 highway, and 19 combined mpg and using 5.3 quarts of 5W-30 API engine oil. Owner data covering 1995 through 2026 records 323 complaints for this year, with structure cited as the top complaint area and six recalls on file—well under the 782-complaint peak seen in 2006. Against that span, the 1998 model sits as a comparatively moderate year rather than a high-water mark for reported problems, giving researchers a useful baseline for Tacoma long-term behavior.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 7,500 mi; spark plugs every 60,000 mi; coolant every 30,000 mi. The big-interval services (every 30,000 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.

In the 1995‑2000 window, complaints rose from 183 in 1995 to 278 in 1996, dropped to 135 in 1997, then jumped to 323 in 1998 before falling to 256 in 1999 and 222 in 2000. Recall counts were steady at 4‑6 per year, with 1998 matching the 1996 and 1999‑2000 level of six recalls, while investigations were absent in 1998 after occurring in 1995 and 1996. Technical service bulletins increased each year, reaching 97 in 1998, up from 91 in 1997 and continuing upward to 103 by 2000. The 1998 model year therefore sits at a local peak in owner‑reported complaints despite recall activity being comparable to adjacent years. Given the higher complaint volume without a corresponding increase in recalls, a buyer may encounter more frequent non‑critical issues, suggesting caution unless a thorough pre‑purchase inspection is performed.
