This may not directly relate to the ITR's but there seems to be lots of knowledge about oil from members of this board. Would you guys use 5w-20 in a K20 engine as recommended by Honda. I know the engine tolerances have been built around the oil and it may be good for a hp or two, but to me that stuff sounds as thin as urine. I am sure Honda is pushing that oil for fuel efficiency reasons mostly, I would feel better running 5w-30 as I plan on keeping the car for a few years. I have always run 10w-30 in my B-series engines, but I don't think the K20 will respond well to 10w-30, so I am thinking maybe 5w-30 would be a better choice, any opinions on this ?, any reply would be interesting. thanks.

My TL Type S calls out for 5w20. I'm running 0w20 synthetic...

 

thanks for the replies, still sounds kind of thin to me though.

 

I threw 530 in my 02 and its fine,and my milage actually went UP finally after changing that shitty break ijn oil and using 91 instead of 87.......I told you how bad my break in oil was on CSi,right? CHOCOLATE MILK,and thats no joke.I never pulled oil that bad out of my old JRSC Si....This crap was BROWN,DARK BROWN and watery.........I know honda says 3500 on the break in oil,but there was no way in HELL i was gonna leave that stuff in any longer than 2K.Im glad i pulled it out after seeing how it looked
