The 2001 Honda Accord runs on regular unleaded.
The question is not can, but should you. Of course you can, but, should you? Use exactly what the owner's manual tells you to use.
Any name brand 5w30 weight oil and a quality filter such as Wix or Purolator. I use Pennzoil oil and Purolator filter.
You can use any name brand oil in your Honda. I use Pennzoil but that is my choice.
5W30.
You can use PH3593A which is a Honda oil filter. There are also other sizes you can use that will fit but they are the Honda brand.
5w20. I personally use Pennzoil in my 2004 Accord.
SAE 5w20 High Mileage oil any major brand. If it is burning oil then use SAE 5w30 High Mileage.
Can you? Sure you can. Should you? No, you should not. The recommended weight oil for a 1997 Honda Accord is SAE 5w30. Use only that weight in conventional or synthetic.
Fram oil filters are really good and will fit just right. Just about all filter manufactures make a filter that will fit on your Honda. I have owned 4 Honda Accords and use nothing but Purolator oil filters.
The 2006 Honda Accord requires 5w20 oil. The close tolerances of the Honda engine require the use of this oil for initial startup. Do not use any other oil and make sure to use a premium name brand oil. Also install a premium oil filter such as Purolator or Wix. Another thing to remember on a Honda. Use only Honda ATF transmission fluid and use only Honda Power Steering fluid. Do not use a generic, universal, or substitute.
Yes you can.
