Don't take this as an advertisement. I don't work for these guys. I HAVE though, spent an embarrassing number of hours researching every chemical and every additive in all the common conventional, part synthetic & synthetic oils.

Yes you can. They are the same part.
To add oil to a 1997 Acura SLX, open the hood and locate the engine oil filler cap, which is typically marked with an oil can symbol. Remove the cap and use a funnel to pour in the appropriate type and amount of oil, as specified in the owner's manual. After adding oil, replace the cap securely and check the oil level with the dipstick to ensure it's within the recommended range.
you can use a 5W30 or 10W30 either or, but if you want the BEST I suggest a full synthetic oil in either of the types.
Use exactly what Acura recommends and nothing else.
