The best lead for your car
Have been using Wynns lead substitute in my old 2 litre pinto engined kit car for 14 years now, and its still running faultlessly. I add a cap full at each fill up, easy to measure in the funnel and to dispense into the fuel tank. Sure i could have the head coverted to take cheap unleaded petrol, but i prefer to spend that money on proper high octane 5 star fuel with the added lead from Wynns. Engine pulls stronger, is more responsive and is most likely more economical to boot. Would highly recomend to anyone needing to run a leaded car on unleaded petrol.

Appears to work short term, long term to come.
Used over winter, seems to work well.Yet to fail. Starting with first firing impressive with motorcycles.Testing with small engines, 2stroke chainsaw, 4stroke leaf blower etc I'll return a Long term use in summer if we ever get one.
