MOTOR MEDIC Lead Substitute is rated 4.3 out of 5 by 6.
Rated 5 out of 5 by from I have an older car that still requires leaded fuel. The Additive seems to work well and keep my older engine running. I haven't had any valve issues.

Rated 2 out of 5 by from Product appears to have been changed. I have used this lead substitute in my 1968 Jaguar E-Type for over 20 years, and it always produced smoother running. with this last batch of three bottles, and given all points, plugs etc. checked and okay, I am not getting the same smooth ignition. Was the product changed? If so, change it back.

Rated 5 out of 5 by from Lead substitute for old cars I'm just grateful this product is available at Pep Boys. I'd be lost without it. Must add lead substitute each time I put gas in my 1964 Ford. Bottle size is convenient. Quality is good. But mainly just grateful it's there at all. Please keep it on the shelves! Thanks.
