Do I need to run a lead additive in my 1950 Pontiac?
Honestly, this is a question for a very experienced cylinder head specialist. Some older engines had problems with valve recession after lead was removed; others had no problem at all. Back in the 90s a mechanic had a radio show Saturday mornings in Phoenix and the subject of unleaded gasoline came up. He related that in a bull session with other mechanics in the area it came out that in their over 100 years combined experience they had never seen an engine with valve recession from unleaded gas. I suspect in England the conversation would have been different - a lot of British Leyland and British Ford engines had trouble if pushed hard. But as Jim Walker posts in the source, "Using additives just about equates with me a 72 year old widower putting on a condom every day - just in case!" I don't know when GM started using hydraulic lifters but if your has solid lifters you should check valve lash periodically in any case. Valve recession shows up as decreasing lash until finally the valve has no lash at all and burns.
Should i run lead Additive in my 1966 ford 289 c code ?
The real purpose of lead was to lubricate the valves and seats, if you don't have hardened seats and can't find a lead additive, then look for a top oil to add to the gas..preferably something with zinc in it.. and also make sure you use a oil that contains zinc, like the racing oils and HD diesel oils.. Texaco introduces Fire Chief gasoline nationwide, a motor fuel that meets the federal mandates .... lead to mandating of unleaded gasoline in 1975 and later-model cars ...This was for the new catalytic converters.
Does my 1963 Ford need a gasoline additive since it was made to run on leaded fuel?
oh, i submit to in concepts this and all the hoo ha while all of it replaced. ok i became into working a 1972 land rover, and it didnt like unleaded because it lacked means while in comparison with 4*, so i used to place ten quids extremely worth of UL and 5 quids 4*, yet now 4* has long previous. in all yet some gargages. UL burns warmer than old 4*, so while youre going speedy, the mixture creates hotspots around the valve seats and burns them out..nicely thats the tale. yet, ive in no way actualy considered or heard of an engine destroying itself below prevalent accepted use. i had a 2.8 v6 mk1 granada, which had the comparable engine..all i did became into alter the timing, and richen the combination a tad. and that used to take a seat down on motorways at between 80 and ninety..ok it have been given slightly warm, yet all of them did...and that they saved on working. 3 years i had that till now rustworm have been given it...and that i enjoyed it. so my suggestion is definite, run your toddler on UL, purely dont thrash it. alter the timing once you ve positioned the gasoline in, slacken the dizzy and turn it untill you hear the revs p.c.. up, and lower back it off a level or 2..adventure shall we me try this with my ear and alter teh combination a screwdriver, detect the main jet and alter it (yet its 3am, and that i cant submit to in concepts whether its a gasoline screw of an air screw , yet while its and air, then a million/2 turn in, and gasoline, its a million/2 finally end up... hear on your engine..you may desire to have the means to tell while its ahppy and while its no longer..its a zen element..and fortuitously older automobile have been person friendly. and youll understand whn you warm hte gasoline whether youve have been given it stunning..inspite of the shown fact that it expenses no longer something to debris around..
What kind of fuel does a 69 chevy chevelle take..?leaded or unleaded ?
Leaded, but I never put it in my old cars. Nothing ever happened to me... I still live with my mom. ;) Mustanger is right, the lead would protect the valves. That being said has anybody ever SEEN a valve seat pulverized due to lack of lead... Niether have I and I've owned a 76 gremlin with a 71 V8 in it, a 72 dart, an 84 dodge van with a 71 slant six, and I currently own a 51 buick, and like I said nothing ever happened to me. I think if my valves ever crap out I will have those hardened seats put in at my local machine shop. Untill then you may as well tell me I need elephant urine in my gas, but I'm not paying extra for it. And I was kidding, I don't live with my mom.
What year did Chevy Impala's switch to No-Lead gas?
first chevy didnt switch to unlead they stop making it and you should be fine running a high octane fuel an dbest way to know which fuel is by testing a few brands and type of octanes way you check is by stoping at place you stop at most fill up with highest octane set mileage or write it down drive til you need to refill an dtry next lower one do the same think one that gets you the most mileage the one you need to use at that place then you stop at place you some times stop at do the same thing you want to know which one gets you the most mileage knowing what brand and type you have to test ... its always been that way ive beed driving and working on my cars. 40 yrs id had a few cars older than your 71 not all fuel same not all drivers same and not all motors are either so what works for one might not be the same you its like my nissan gets great mileage with shell high octane but gets the same with mobil regular its something you have to work out as driver

Lead Additive:What year did chevy start using hardened valve seats for unleaded fuel use?
It was 1973 and you can add gas additive and run regular or mid grade for best Performance Lucas makes an injector additive that will help with the valves and since it has run lead in it before the chances are it won't bother the seats anyway as it already has the lead pounded into the valve and seats already. Your biggest problem is going to be alcohol it will eat the old valve guide seals so again the lucas additive with help with that you will also have problems with the crank case ventilator valve and the carburetor float. if you get a chance to replace it do so, if it has a Metal one your ok, but the foam floats that came with them will burn the engine down when the alcohol eats the neoprene off the float, and add a fuel pump too as it to will give up the Ghost because of the alcohol and the fuel filter as well. buy new pump and filter that won't disagree with alcohol since our good government decided to make it mandatory to burn in all fuels now.
What can I add to my daily intake of water to make it more nutritious?
If your water is filtered, it's already healthy, unless you filtered out all of the natural minerals. Additives to clean drinking water are not necessary when we concentrate on eating nutritious food. The only time I would recommend additives to water is if it were distilled. Distilled water can flush the body of minerals and/or cause the cells to absorb too much water causing bloating or even congestion. If you filtered chlorine and flouride, as well as heavy metals like lead, the water needs only a few electrolytes such as very small amounts of sodium chloride, potassium, maybe trace amounts of calcium and magnesium. I'm a big fan of moderate vitamin suppliments, but not in water. Your filtered water should be fine without additives.
How does a radiator overflow tank work?
Think of your radiator like a pressure cooker: the weight on top of the cooker opens a valve to release excessive pressure. If the valve didn't open up, you would have a steam bomb. Now imagine that the cooker is a radiator filled to the top with coolant. As the engine passes heat into the closed cooling system, the liquid expands with the heat. The pressure would keep building until something blows, but luckily there is a pressure cap which releases extra pressure. The coolant flows out of the cap into an expansion tank. There cap has a spring which opens at 12 to 15 lbs of pressure. When the system starts to cool, a vacuum is created within the radiator: this again allows coolant to flow but in the opposite direction. The expansion tank has a hose which allows coolant to flow back into the radiator. For the system to work correctly, you need enough coolant in the overflow and a working cap, otherwise you'll draw air into the system. Air doesn't dissipate heat well.On some cars, Ford, and BMW for example, the overflow is pressurized and a part of the radiator. I assumed that this is to increase the cooling efficiency of the system without having to increase the radiator size or airflow front the front of the car.A little tidbit: older engines did not have to pressured system. The radiator was under filled to allow expansion. This worked well when cars didn't have to meet emissions and could use fuel and oil for cooling. Also, an old school cast iron engine can be overheated and still be usable after changing a headgasket.
