Morris Minor Owners Club

There's been some chat about Redex Lead Replacement additive around here recently and I've been making some enquiries.

There's lots of Redex products around there's days, Injector Cleaners etc, but they still offer a Lead Replacement/Upper Lubricant; it's just not as readily available as the stuff aimed at the more modern motors.

If you look at Fleabay, there's lots about, with various labels, some stating part number RADD1301A, others listing RDX18, with many not saying which they are...

This one even claiming both numbers!!

I contacted Redex (Holts) and the prompt reply was that RDX18

ceased to be a product in the portfolio more than a handful of years ago – we wouldn’t advise using any stock that is stamped RDX18.

So if you are buying Redex Lead Replacement, you might want to bear that in mind.

thank you for the info i am one of the members who is using redex and the ones i just bought are the latter part number

Generally speaking though, Redex, if stored in a cool, dry place (e.g., garage, shed, etc.) can last for years and be perfectly fine to use, in my experience.

I now use this Millers product. In addition to being a Lead replacement, it claims to protect classic cars' fuel systems from Ethanol damage. It also claims an enhancement of up to 2 Octane points. After a few hundred miles usage my Minor seems to pull more strongly up a local main-road hill, and tickover speed has risen (not a very scientific test, could be other unrelated reasons).
