hello dieseldude, i own a kia sportage gen1 kr2 2.0l diesel, model 1997 i think. any idea on why sea-oil diesel gives a low rpm - flat on the 2/3 line at idle as against shell/petron which a tad higher around 5rpm. power's about the same on highway or hilly roads. location is Zamboanga City. thanks, this thread is most useful and practical. more power!
