- All I can offer is that I converted to Mobil 1 when my 89 Probe had
- about 25,000 miles on it. After about a month, my gas mileage went
- from an average 29.5/gal to 31.5/gal (at least that was before they
- put this oxygenated horse urine in the pumps). If I get longer
- engine life, its a bonus since I figure the better gas mileage
- pays for the higher price. Just one man's experience.
