– Engine Compatibility: Check if the oil is suitable for your engine type (gas or diesel) and driving conditions.
– Longevity: Opt for oils that offer extended protection, reducing the need for frequent oil changes.
– Brand Reputation: Trust brands known for quality and performance, like Mobil 1, LIQUI MOLY, or Royal Purple.
– Price and Value: Balance cost with benefits. Higher-priced oils often offer better fuel savings and engine protection.
