98 Prelude Base with 186,000 kilometers. Since i have owned the car i have heard all about the oil usage/burning/disappearing of the H22, people having to dump oil in all the time. Well i have been keeping an eye on my oil like a hawk. I have heard many different people say the "normal" usage for an H22 is +/- a litre(quart) every 1000 km depending on driving habits and milage it could be none or even more. So i realize its a norm of H22 ownership. The first 2000kms i put on it i didnt use a drop and the etest showed nice and clean and that it didnt seem to be burning any. Then all of a sudden the oil is below half, so i filled it back up and its steadily seemed to use oil every week, some days only a gulp. Also replaced PCV valve. Guy and Honda told me to put an engine cleaner in and see if maybe your oil control rings were gummed up. So i did and since then its been 600km with some heavy driving and it doesnt seem to be using any or atleast not much that i can notice. Also my buddy told me that a puff of blue will come out only on WOT for maybe a second, so nothing excessive there. Now the dipstick seems to be misleading some days, one day its full, next its down a quarter, so ill top it up, next day its way above the full mark. Could oil be getting trapped somewhere? Is this normal? Cause im starting to think that ive just been putting too much oil in it when it doesnt actually need it and its burning it off because its too full? Ill be switching to 10w-30 in spring, see how that goes.
