SFR 100 All Purpose Oil Fortifier 1 Gallon 128oz

This is an amazing additive product I've used for over 10 years in many different vehicles.

just look at the video testing they do. I have use this item for +20 years. Very expensive but works wonders.

SFR is great. Highly recommend it.

The fortifier is excellent and for the application of a 30 weight fortifier for small bearings has been Wonderful. However at $150 per gallon, the company needs to improve their quality control to make sure every gallon comes with a full gallon. It should not be 3 and 3/4 quarts of oil. A 1/4 quart is the equivalent of shorting a customer $10 worth of oil. Yes, it works great. And yes, it is even more expensive than you thought.

good product
