Whatever you want, And if someone tells you that you can not change to A different brand of oil, BULL!, I have owned about 500 cars and I change to my favorite brand oil on every single one of them. Oil does not soak into metal, when you change the oil on A car that requires 5 quarts there is only about 1/15th of A cup that does not come out. It would not hurt to have the same amount of water put into the oil, So another oil will not matter either.
you can use 10w30 oil or 10w40 either one will work
I used Valvoline VV155 MaxLife SAE 5w30 Motor Oil in my 1990 acura legend
you can use 10w30 or 10w40 either is fine
Usually use a 5 quart jug high milage on my 93 legend. Give or take, thats about all it should need.
the type your ownswers manual says, or 5-20
5w-30
5w30
Use only genuine Acura or Honda fluid and nothing else.
Use only Honda P/S fluid.
5w-20 and it takes 4.5QTS
I do believe it is the same body style and most things should transfer over to the 1993. It may have some electrical differences but not many. You can also transfer parts from a 1994 Acura Legend.
It is important to use the correct amount of fluid in a car. The 1988 Acura Legend takes about 3.2 quarts of transmission fluid.
