Hello. This morning while I was taking my husband to work in our Toyota Camry, I was trying to catch a green light but didn't make it on time, so when I braked, the little red engine light flickered. It didn't stay on though? I'm pretty sure it means I need oil because my last oil change was in July. My question is how much is an oil change? For labor and everything. And how long can I drive my car before the engine cracks? I would ask my husband but we both are young and don't know much about cars. Thank you in advance.
