Q:Hasn‘t been rebuilt. Old 289 from 66 mustang. I‘m talking about how fuel in the 69s had lead which I think protected the valves but now with unleaded gas I heard that it could ruin the head.

An engine from 1966 would have been designed for leaded gasoline. Lead was added as a lubricant to prevent wear on parts such as valve guides.

Q:I found out that beer companies have lobbied so that they don‘t have to list their ingrediants on the bottle. Do you know of any websites that lists the ingredients?

NONE! Beer is made out of THREE things! Hops, water and barley - PERIOD!

Q:that additives make the concrete more shine and use it as afinishing levle

I think you're thinking of two separate things. There isn't anything you can add to the concrete mix that will make it shine when it's finished. A shiny concrete floor is one that has been finished with a power trowel,( or Whirly-Bird as they're sometimes refered to). These make the floor very smooth and easy to sweep. Large home centers and big box stores often have these. Concrete color additive is a liquid or powder dye that changes the color of the concrete, but won't make it shine.

Q:I‘m all for vaccinations but my wife believes they cause Down syndrome and more harm then good in infants. I finally talked her into letting us give them to our future children IF I can find vaccines without any additives like Aluminum salts, or formaldehyde and what not.

You amp; your wife should read Dr. Robert Sears book The Vaccine Book it gives an unbiased look at vaccines amp; the deceases. It#x27;s very detailed amp; gives lists of ingredients in each vaccine amp; so much more. Be completely informed first then make your decision. :)

Q:The info on their website states that they can guarantee 15% to 20% better gas milage. You ad 1 ounce per 10 gallons of gas, and the company says the engine is more fuel-efficient and releases less polloution. Has anyone had any experience with this product?Thanks

15% to 20% improve is practically impossible. any fuel additive that claims that kind of performance, it's a scam. although you can still use the additive to help clean up your fuel system, but that's very minor too. Don;t waste your money on fuel additive and make your to keep your car tuned.

Q:I was wonder is it a good idea or not to put oil additives in a new or high mileage engine for added protection. If you think it is a good idea what additive would you recommend? I remember back in the 60s and part of the 70s it seemed like everyone was using STP then they started to say it gums up the engine. Soon you couldn't find STP. What would your thoughts be on the use of additives??

I still find STP. And a hooey of other products. A high mileage engine don't need protection anymore. There is nothing to protect. It is on the worn out stage. You will notice this by the oil leaking as the cork or rubber gaskets was not meant to hold back compression pressure>which is escaping past the rings and entering the crankcase and valve cover. You may also notice a blue haze coming out of the tailpipe. That is an oil burner. An additive you may want to use is calledNo Burn" which hides the blues your car is now puffing. You need a motor job or another engine with less miles on it. You may want to try the additive that slows down oil leaks or up the viscoscity of the oil. Instead of 5W20, maybe straight30 weight. 20/50W is for motorcycles, not cars. so leave it alone. If you are still smoking to beat the band with 30W, then the motor is >Hatched<

Q:The best way to use the red line additive should be every 5000 km in the empty tank state of the whole bottle into, and then fill the tank on the high-speed! Sub-scale grading plus the effect is not very obvious. Another friend suggested that the old car by the first method may cause the use of three-way catalytic clogging

Because the old US also found that the whole bottle down to write more sales, the effect is more obvious. And eat the same as the WG. The The A scale plus a scale effect in fact the same, as you used to 8T on the numb, and did not feel how strong the power

Q:What is the best oil and fuel additive for a Mercedes?

Crack the manual in the glove compartment to read what Mercedes has to say about goofy fuel and oil additives.
