Here's why and what to consider:
* Owner's Manual: This is the most crucial source. The manual will specify the recommended viscosity (like 5W-30) and oil type (conventional, synthetic blend, or full synthetic). Pay close attention to this information.
* Engine Wear: A 2000 vehicle is likely to benefit from a slightly thicker oil (like a 10W-30 if recommended by your manual) to help compensate for some wear on internal engine components. However, ALWAYS follow your owner's manual recommendations.
* Climate: If you live in a very cold climate, a 5W-30 or even a 0W-30 (if your manual allows) will provide better cold-weather starting. In extremely hot climates, a 10W-30 might be slightly better, but again, consult your manual.
* Conventional vs. Synthetic Blend vs. Full Synthetic:
* Conventional: The least expensive, but offers shorter life and less protection in extreme conditions.
* Synthetic Blend: A good balance of price and performance. Offers better protection than conventional oil.
* Full Synthetic: The most expensive, but provides superior protection, longer life, and better performance across a wide range of temperatures.
In summary: Check your owner's manual first. If it recommends 5W-30, that's a great starting point. A synthetic blend 5W-30 is a good compromise between cost and performance for a vehicle of that age. Don't forget to also check the oil's API certification (look for the "donut" symbol on the bottle) to ensure it meets the necessary standards.
