Here's why:
* High Mileage Specific: These oils often contain additives designed to help condition seals, reduce leaks, and protect against sludge buildup common in older engines.
* 10W-30 or 15W-40: These viscosities are suitable for a 318 in a variety of climates. 10W-30 is a good all-around choice, while 15W-40 provides slightly thicker protection, especially beneficial in hotter conditions or with higher mileage. Check your owner's manual for the manufacturer's recommended viscosity.
* Conventional vs. Synthetic Blend: A conventional high-mileage oil is a cost-effective option, while a synthetic blend offers improved protection and longer drain intervals. The choice depends on your budget and how frequently you change your oil. Full synthetic is an option, but the added cost might not provide a significant advantage over a high-quality synthetic blend for a high-mileage engine.
Before making a decision, consult your owner's manual. It will specify the recommended oil type and viscosity for your specific year and model of Ram 3500. Always prioritize the manufacturer's recommendation.
Finally, remember to regularly check your oil level and change it according to the recommended schedule or sooner if you notice any unusual wear or performance issues.
