What's the difference?
Conventional oil is refined from crude. Synthetic is engineered for uniform molecules that resist breakdown at high temperatures and flow better when cold.
Why it matters in Texas
Engine oil temperatures climb fast in 100°F traffic. Synthetic oil resists thermal breakdown, keeping engines cleaner and better protected.
Is it worth the cost?
Synthetic changes cost more but last longer — often 7,500–10,000 miles versus 3,000–5,000. Per mile, the cost difference is small, and many modern engines require synthetic.
Our recommendation
Always use the grade your manual specifies. If your car allows either, we recommend full synthetic or a synthetic blend for Texas driving.
