Slick 50

Is Slick 50 Any Good For Your Engine? And How About Fuel Injector Cleaners You Add To Your Gas Tank? 1996 Monte Carlo V6 Ls 3100 58,000 Miles
Thank You

Here is a copy of a post I made back in April 2005 in the Venture forum, and most recently re-posted in the Lumina forum concerning the use and overuse of fuel injector cleaners. I hope it is good information you can use to determine whether or not you want to use such cleaners.
""If you are going to add any cleaner in your tank DO NOT put it in an empty tank. Put the cleaner in a full tank of fuel, or as you prepare to fill the tank at the gas station. Fuel injected vehicles use an electric fuel pump in the tank. The pump passes the fuel through the pump windings to cool the pump. The fuel cleaner can eat the varnish insulation off the fuel pump armature windings and damage the pump, or rendering it useless. Auto manufacturers make sure that the additives found in pump gas won't hurt the pump, but do not run any tests with the aftermarket cleaners. Sometimes the apparent damage to the pump from adding the fuel cleaner on an empty tank may take a few days to manifest itself, thereby posing the risk of becoming stranded. Use the fuel cleaner as little as possible. Constant unneccessary use can accelerate problems with fuel pump failure. Not all aftermarket fuel additives are harmful, but why take the chance in discovering the one you are using is one that will eventually cause damage?"
I occasionally use a fuel injection cleaner. I have had good luck using the Lucas brand cleaner. I really don't have an opinion about the use of Slick50 as I don't use it. I have heard more negative than positive comments about it however from friends and associates. I have used GM's EOS ( Engine Oil Supplement) found at your local GM dealer's parts counter. I also have used it as an assembly lube when I rebuilt my engine with good results.

Are you experiencing some sort of problem? Slick 50 does nothing to reduce engine wear, and may actually be harmful. If you really want to protect your engine and reduce wear, switch to a full PAO synthetic lubricant (NOT a "synthetic blend" or Group 3 "synthetic" mineral oil).

Fuel injector cleaners are usually not necessary if good, clean fuel is used, the filter is maintained, the EVAP system is intact, and the air filter is maintained (many injector tip deposits and engine oil contamination are due to atmospheric dust pulled through the air filter).

Instead of injector cleaner, periodic use of ethanol blended fuel can help keep injectors clean.
