Yes a bottle of Auto-Rx is expensive, but it is cheap compared to what repairs you would maybe have to do to your engine. Let's take a small block chevy, because that is what I am used too. With Frank's product, you would not have to replace:
1) Valve Seals since they would be lubricated and kept soft and pliable.
2) No replacement of the rear main seal since it would be pliable.
3) Since oil is getting everywhere in the engine the parts that need lubrication, like the camshaft, pushrods, rocker arms, would not need replacing.
Maybe eventually these things may need to be replaced, who knows, but instead of having these problems at 150,000 miles maybe you would see these problems at 400,000 miles. This may be an outlandish statement but my small block with 363,000 miles is running better than it did at 200,000 miles. So in the long run parts replacement and the labor if you can not do it yourself are more expensive in my opinion.
