The car's EPA rating was 39-43new -averaged 41 the first 37thou and since, the last almost 100thou, 43.03 mpg. I have a 10.3gal tank and add 2oz. per 6 to 8gal fillup. My oil samples were posted in the oil sample section a few months ago. 98 Suzuki Swift 15000miles using Mobil 1 EP. It was around the first of this year. Had a 96 Geo Metro before that I never used UCL in and it averaged the same 41mpg(same EPA rating 39-43) for the 216+thou I drove it also(todays car- same, just newer) wish I had used it back than.
