Oil Change I want to know what kind of oil do I need to use in my car? it's a 2003 corolla with 95000 miles. I need to change the engine oil, what kind of oil should I use?

Drain engine oil and replace oil filter(your local automotive store will have a book telling you what oil filter you need to buy). You've probably been using a multi-grade 10-30 or 10-40 weight oil. Or a straight 30 weight oil. Regardless, replace that oil with one grade heavier, single-weight of oil. During warm months, use 40 weight; in the winter (depending on how far the mercury dips in your part of the country) use 20 or 30 weight. Slightly thicker oil won't hurt that worn engine, and if your battery is good, it'll turn over fast.
