Using a Diesel fuel conditioner would be good for your engine and would not be bad at all.
not a good idea.
Only if someone installed a diesel engine. Most Explorers are gasoline engines.
If the non diesel fuel is drained out without getting to the engine there is a good chance there wil be no damage. For more information see the answer to the Related Question shown below.
not at all. that will cause engine damage. gasoline burns at a much lower temperature than diesel fuel so you will get pre ignition. diesel fuel has more useable power in than gasoline. gasoline is rated in octane and diesel fuel is rated in cetane. with diesel fuel the higher the cetane the faster the fuel will burn for a more complete combustion. so if you want more power from a diesel a place to start is a higher cetane diesel fuel. but things like bigger trubos, vgt turbos, injectors, intercoolers have a much bigger effect on power than fuel
For use as an engine lubricant - no.
Diesel is not gas, it is a liquid fuel. diesel is a liquid fuel obtained originally obtained as a waste product after oil has been refined into petrol the diesel engine was invented by a guy named diesel and his invention was ignored untill after his death when it was found that it was a good engine and used up the refinery bi-product and that also is why deisel became named deisel
the fuel injector pump needed cleaning, its working good now
NO, I have seen it done for awhile. (Diesel fuel is an oil.) But eventually the gas engine will stop running (if residual gas remains in the tank) due to failure to burn completely in a gas engine. Expect carbon buildup and dirty spark plugs prior to it stopping. But diesel fuel does interact with copper fuel lines so that's not good either.
No, never put diesel in a gasoline engine it will foul up the sparkplugs in your engine, clog it up, and make it smoke alot. Cold Diesel in a diesel engine isn't too good either because when diesel gets cold it gels up, that is why most diesel engines have a built in heater to warm up the engine and fuel before starting. Hope this helps
No, you never, ever, store gasoline in a diesel can under any circumstances. Good way to cause someone to ruin a diesel engine if they used this fuel or someone to get badly burned using this to start a fire thinking it was diesel fuel. Only a utter fool would do this.
Diesel smoke is often caused by fouled injectors, in which case the smoking can be cured by pouring a dose of good injector cleaner into the fuel tank on the next fill-up, and change the fuel filter, too. And change the engine oil and filter!
it can be but is not going to help with performance. depending what sort of diesel engine you have, depends on what you can do to improve performance a good diesel mechanic can turn up the fuel pump, change injectors etc. vehicles with computers can have chip added that vastly improves performance and is easiest way to go
