The only additive you need is pure acetone for fuel efficiency. Search the web for Acetone as a fuel additive. BTW Acetone is the main ingredient in fingernail polish remover You add 2 oz. to every 10 gal of fuel you put in your tank. It makes gasoline burn like the perfect fuel .Propane
well, an OIL additive will probably not help that. a FUEL additive will stop the pinging if its due to the cheapskate behind the wheel who doesn't buy the expensive gas. hey dude, gm and chevy are the same company. and since when are college professors telling the truth to anyone??
If you're talking fuel additives, I'd be very dubious; most big brand petrol/gasoline will have all the necessary additives already in it. I've heard horror stories of gummed up injectors and such, after using aftermarket additives. Not worth wrecking your engine for.
c. Fossil fuels Swampy / coastal - shallow marine environments contain a lot of organic material, especially buried vegetation which decomposes can become oil, coal or natural gas. a. Copper isn't the answer - copper deposits are generally found in igneous rocks or tectonically altered sedimentary rocks near igneous rocks. (As an exception, the Zambian Copper Belt is hosted within shallow marine rocks.) b. Iron Ore isn't the answer - these deposits generally form in Precambrian skarn settings d. Halite isn't the answer - these deposits form as evaporite deposits in shallow, clear waters where the rate of evaporation is significantly greater than new marine (salt water) supply.
