Toyota Corolla Natural Or Synthetic Oil? Q. 2003 Toyota Corolla LE with 7,615 miles. I did an oil change to my car today, and after putting in the new oil I noticed that the oil was synthetic; Mobil 1 5W-30 and it is recommended that I use SAE 5W-30 oil in the manual. Will this have any kind of negative affect, and for the next oil change will I be able to go back to SAE 5W-30? I hope that you can help me in this matter. Thank you, Luke

A. No problem. Next oil change you can go back to the natural 5W-30 or stay with the synthetic 5W-30 oil.
