Buying Guide
Choosing the right gear oil for your Dodge Challenger can seem daunting, but it doesn’t have to be. Here are a few key factors to consider:
- Viscosity: The recommended viscosity for most Challengers is 75W-90. Check your owner’s manual to confirm the correct specification for your model year and drivetrain.
- Synthetic vs. Conventional: Synthetic gear oils offer superior protection and performance compared to conventional oils. They resist breakdown at high temperatures and provide better lubrication. While they cost more, the benefits often outweigh the expense.
- Limited-Slip Differential: If your Challenger has a limited-slip differential, make sure the gear oil you choose is compatible. Some gear oils already contain the necessary friction modifiers, while others may require you to add them separately.
- Driving Style: Consider your driving style and usage. If you frequently track your car or drive aggressively, you’ll want a gear oil that’s designed for high-performance applications. For daily driving, a good quality synthetic gear oil will suffice.
- Brand Reputation: Stick with reputable brands that have a proven track record. Read reviews and ask other Challenger owners for their recommendations.
- Climate: Consider the climate where you live. If you live in a very cold area, you may want to consider a gear oil with a lower “W” rating, such as 75W, to ensure proper lubrication at startup.
By considering these factors, you can narrow down your choices and select the best gear oil for your Dodge Challenger.
