all those who are skeptical about using delo 15w40 in their honda manual gear boxes, you may pour them without a doubt in mind. I too was skeptical but I trusted the experts here and my car hasn't caused me any distress for the past 6 years. I simply get the oil drained and replaced every 2 years.
in short, if you want to go for honda's own mtf, you may do so with eyes closed but if you want to get the same stuff at a reasonable price then get the caltex delo gold ultra 15w40.
