OK, the last two accords I have had a 90LX and 89LX both suffered from rod bearing failures right after I got them. I just recentally acquired another 90 LX iand the oil is very brown and think owner says he had 20w50 in it. I want to switch to 10w40 but dont want it to knock. should I stick with 20w50 or take the risk with 10w40. car has 229,000 on it told bottem end and head gasket was done.

I wouldnt change the oil, that 20w50 is prob. holding it together.

 

Change it out and throw in some Castrol 10w30. Old dirty oil does not hold an engine together, by any stretch of the imagination.
