Over the years, I've heard so called "testimonials" claiming by switching to a particular brand of synthetic oil, the user experienced a 15% to 20% increase in mileage. I dont doubt that synthetics may flow easier, but these statements seem unrealistic. There's so many other variables, such as fuel quality, wind, air density, temperature, ect. Anyone know of dyno tests that showed a comparable increase?
While were on the subject, I also noticed on the Lucas UCL that it states "This product should more than pay for itself in fuel savings alone". Anyone have proof?
