Blending Smoke-Free SF-10™

Dave and George are blending Smoke-Free SF-10™ today . SF-10™ is an engine oil additive designed to eliminate excessive exhaust smoke caused by worn parts in older or high-mileage vehicles, or in the case of the follow-up video testimonial we received, older tractors.

Thank you Brett Allen Morgan for your feedback and testimonial after you used SF-10™ in "Homer".
