2015 Dodge Viper maintenance schedule

The factory schedule for normal driving. Oil changes follow the oil-change indicator on most models; severe use (towing, dusty roads, lots of idling) shortens some intervals.

A dot means the service is due at that mileage.

  • Change the engine oil and engine oil filter
  • Rotate the tires, rotate at the first sign of irregular wear, even if it occurs before scheduled maintenance

2015 Dodge Viper recalls & safety

What the U.S. government's National Highway Traffic Safety Administration (NHTSA) has on file for the 2015 Dodge Viper: 1 recall campaign and 3 owner complaints. Fetched November 8, 2026.

NHTSA hasn't published 5-Star Safety Ratings for the 2015 Dodge Viper.

Recalls (1)

Newest first. A campaign covers certain vehicles of this model year, not necessarily every one. To see which apply to a specific vehicle, and whether the fix has been done, enter its VIN at nhtsa.gov/recalls or ask a dealer; repairs are free of charge.

Equipment: electrical: radio/tape deck/cd etc.July 23, 2015 · Campaign 15V461000

Chrysler (FCA US LLC) is recalling certain model year 2013-2015 Ram 1500, 2500, 3500, 4500, and 5500, 2015 Chrysler 200, Chrysler 300, Dodge Charger, and Dodge Challenger, 2014-2015 Jeep Grand Cherokee, Cherokee, and Dodge Durango, and 2013-2015 Dodge Viper vehicles. The affected vehicles are equipped with radios that have software vulnerabilities that can allow third-party access to certain networked vehicle control systems.

Risk: Exploitation of the software vulnerability may result in unauthorized remote modification and control of certain vehicle systems, increasing the risk of a crash.

Fix: Chrysler will notify and mail affected owners a USB drive that includes a software update that eliminates the vulnerability, free of charge. Optionally, owners may download the update to their own USB drive from http://www.driveuconnect.com/software-update/ or take their vehicle to a Chrysler dealer for immediate…

Salt, snow and hills: the data

Reading the 2015 Viper data for Great Lakes roads

None of the factory data on this page changes from one region to the next, but what deserves a second look does. Below are the 2015 Dodge Viper lines that matter for an Evansville winter, a spring of broken pavement, a boat on the hitch or a long descent in the hills.

Tire choices for squall and thaw

Big wheels look good, but after a March commute on Detroit or Cleveland streets they are the ones that come home bent. This year's sizes run from P295/30R18 on 18-inch wheels to P355/30R19 on 19-inch wheels; the smaller fitment carries a taller sidewall that absorbs pothole strikes and usually costs less to replace.

What the manual says about oil

Factory oil: SAE 0W-40, 11 qt per change with a filter. A Grand Rapids or Toledo January can leave an engine at single digits overnight, and at start-up the oil has to reach the top of the engine fast. The 0W part of the grade is its cold-flow rating, so keep it rather than going thicker for winter. Short trips that never fully warm the engine let moisture collect in the oil; a longer drive clears it.

Cranking power for a lake-effect morning

Rated battery output: 600 cold-cranking amps, measured at 0°F. A single-digit night in Traverse City or Fort Wayne cuts what the battery can deliver just as the stiff engine asks more of the starter. Past three winters, an October load test tells you more than the date sticker. Charging comes from a 180-amp alternator.

Traction for snowbelt hills and hollows

Every 2015 version in the factory data is rear-wheel drive; no all-wheel or four-wheel drive was offered. That works through a Great Lakes winter on proper winter tires, which matter more on packed snow than the number of driven wheels. Hills are the harder test, from steep Cincinnati side streets to back roads in West Virginia, so carry momentum gently and avoid spinning the tires.

Pressure, potholes and the thermometer

Whatever size the Viper wears, from the factory P295/30R18 on up, correct inflation is the cheapest pothole defense there is: a soft tire lets the wheel slam into the far edge of the hole. Check pressures when the tires are cold, since a reading taken after a highway run will look high. The schedule pairs pressure checks with a look for unusual wear or damage, which is where a bent wheel or knocked alignment shows up.

Antifreeze for both ends of the year

The system holds 16 qt of OAT coolant (10-year/150,000-mile formula). Stellantis manuals call for a 50/50 mix, good to about -34°F (-37°C), which is colder than a typical Great Lakes winter night; the real risk is dilution from top-ups with plain water. The same mix raises the boiling point for a loaded summer climb through the Tennessee mountains. A cheap tester checks the strength each fall.

Octane from the owner data

The owner data specifies 91 octane. A higher grade than the manual asks for adds cost without benefit, while a lower one than required makes the engine pull back ignition timing, which shows most under load on a long Appalachian climb.

Capacities, ratings and service intervals: Stellantis data for the 2015 Viper. The Great Lakes reading of them is independent and is not factory or dealer advice.

2015 Dodge Viper questions
