Does lead Substitute work?
It’s excellent as a lead substitute. Not only that, as its name suggests, it boosts octane up to four numbers, which is just as important in older high-compression engines that were made with leaded gas in mind. Just one treatment reduces engine knock, improves ignition and helps fuel burn cleaner.
Do I need lead additive?
In conclusion, if you’re really passionate about classic cars, lead fuel additive is definitely a good thing to know about and consider. It probably isn’t essential for most vehicles, but it definitely isn’t going to do any harm and can help some older engines prevent premature valve issues. Ultimately, it’s up to you.
What is lead additive for?
While lead is added to gasoline for the purpose of raising octane number and therefore allowing higher compression and more efficient engines, it also has other effects on engine operation. Lead salts are formed by the combustion of lead additives and are deposited on the walls of the combustion chamber.
Does lead Substitute increase octane?
Incidentally, lead also is used to boost octane or anti-knock quality to gasoline. Powershield does not boost octane. So, if your old engine needs a high-octane fuel, you might consider using an unleaded premium gas with a lead substitute.
What happens if you put unleaded fuel in a leaded engine?
It’s not recommended. While your unleaded car might run fine with leaded petrol, filling up with it regularly will probably damage its catalytic converter – the component that helps reduce pollutants that come from your exhaust system.
What replaced lead in fuel?
When faced with the removal of lead as the primary octane provider in gasoline, refiners had two available alternatives, BTEX and ethanol. The refining industry invested in additional refining capacity to replace lead with BTEX, a high-octane petroleum refining product.
Can you still buy lead additive for gasoline?
Effective January 1, 1996, the Clean Air Act banned the sale of the small amount of leaded fuel that was still available in some parts of the country for use in on-road vehicles. EPA said fuel containing lead may continue to be sold for off-road uses, including aircraft, racing cars, farm equipment, and marine engines.
What is the best lead fuel additive?
Classic Valvemaster, formerly branded Castrol Valvemaster, is the most effective and cost-effective lead replacement additive available for the protection of early vehicles designed to run on leaded fuel.
Are hardened valve seats necessary?
Pretty sure you need the hardened seats for unleaded gas. Almost all the head manufacturers advertise (hardened seats). If you are only going to use the car for your stated mileage, the non hardened iron seats will last you about 5 or 6 years.
What fuel do old cars use?
Cars initially manufactured before 1986 can usually run on unleaded (ULP) or premium unleaded petrol (PULP). However, some older cars may require (a) leaded petrol additive or (b) an engine conversion to unleaded.
Why was lead used as an additive in gasoline?
Today I found out why lead used to be added to gasoline. “Tetraethyl lead” was used in early model cars to help reduce engine knocking, boost octane ratings, and help with wear and tear on valve seats within the motor. This causes loss of power and damage to the engine.
How do you add lead fuel?
How to Make Leaded Gas
- Start with some gasoline. An internal combustion engine uses sparks to ignite the gas.
- Reduce knocking and pinging by improving the power of your engine. Your car’s engine operates under high pressure.
- Use a compound called tetra-ethyl lead.
- Take your ethyl fluid and blend it into your gasoline.
Will 110 octane hurt my car?
High octane race fuel is sort of the same way. So, the moral of the story is; unless you have at least 12:1 compression (of more), do not run any 110 octane or higher race gas in it or you’ll go slower.
What happens if you put too much octane booster?
The higher the octane rating, the slower and colder the fuel burns. If you run too much octane in your engine it won’t run very well because the burn is way too slow. If the octane is too high, the piston might already be at bottom dead center (BDC) and the fuel might still be burning.
Is higher octane gas better for older cars?
What if I use a lower octane fuel than required for my vehicle? Using a lower octane fuel than required can cause the engine to run poorly and can damage the engine and emissions control system over time. It may also void your warranty. In older vehicles, the engine can make an audible “knocking” or “pinging” sound.
