Potions/Additives/Remedies that Work

[Frenchfish63]

I have had a lot of old cars in 40 plus years of motoring,mostly costing under £500 until recently.
The products that have helped keep my motley collection going are;
Holts radiator stop leak.This product has worked time and time again.
Holts tyre weld.Helped many times,lasted the life of the tyre.
Wynns DPF cleaner,add to tank.Sorted out diesel RCZ DPF
Wynns turbo cleaner.Worked on my Megane.
Would like to know,what people’s recommendations are?

For years I was a pretty loyal Wynns product user and always found their products good as long as you use them correctly. More recently I have been using Liqui Moly products for engineering purposes, Carplan for cosmetics and Shell lubricants!!

Long Ago,STP(Scientifically Treated Petroleum). Molyslip grease* and Molyslip G gearbox additive, Coppaslip grease, Forte Cooling System Flush and Forte Cooling System Sealant.

These days nothing really, leave it to Danny (Polish car mechanic who does the oily bits and sells me cars).

*still have a tin of that that my dad posted to me when I lived in Sweden, that would be early seventies. Never needed it as only used company cars.

Saw that and thought it was just my alerts being wonky.

This got me thinking but took me in a very off-topic not Citroen direction , maybe better in the off topic forum ?

STP sponsored the March F1 team back in the 70's, March 711? with a curious tea tray fitted above the nose. They said for aerodynamics but I reckon it was for the mechanics to put their coffee mugs on when they were working on the car. Saw one at Clermont Ferand in 1972 but it wasn''t the March team , I think someone bought and raced the '71 car. Enough of that.

My father was a fan of RedEx - upper cylinder lubricant - sold at the petrol pumps, one shot per gallon, when pumps had attendants back in the 60s. Don't know if it did any good or was just smartly marketed 'snake oil'. The only additive I recall using was anti-figeant (as Citroen called it) which was an anti wax additive for diesel when taking my BX to very cold places but I think the stuff that comes out of the pumps these days has it in already. Diesel cars were unusual back in 1984 and I often had to fill up at the "truck pumps". We no longer hear of lines of trucks stranded on Shap Summit with diesel filters blocked up when its -20. I wouldn't dare add anything to a modern synthetic oil, who knows what it might do. The Maxi needed a jar of Barrs leaks once when there was a dribble from the heater matrix, worked for a while and it saved having to take most of the car apart to get to the leak. Copa Slip and Hermetite occasionally but they weren't really potions, just used for diy "mechanic work".

So its been a mostly potion free 50+ years for me: supermarket shampoo for the occasional car wash* and every 3 years or so I put some polish on from an old tin of turtle wax c. 1985.

* Hot hint of you live in a hard water area and have a dark car. Final rinse with a watering can filled from the garden water butt so it dries without white hard water deposits. Took me 25 years of living here to work that out. And if the neighbour oppsite that you don't really like much looks and says "what are you doing" you reply "I wish I'd bought a bigger car, hoping this one will grow". At which point he retreated shaking his head.

But a question: should I treat my wife's air bumps with anything to keep them in good condition?
