What about Oil Additives
Without going into extensive detail here's what you need to know about aftermarket oil additives: There are basically two types of additives used, either Teflon based with PTFE or Chlorinated based with some type of carrier, usually a paraffin based carrier or other mineral oil. Some have extremely large amounts of moly, zinc or phosphorus, all extreme pressure agents which are detrimental to a motor oils proper function in the amount that they use.
Teflon(PTFE) does absolutely nothing inside your engine. Teflon must be heated up to about 800º F before it will stick to anything for friction reducing purposes. The only time your engine will see this type of temperature is in the recycling center as it is being melted for future use.
These microscopic Teflon particles will gradually attach to your oil pick-up screen, internal engine components and passages reducing oil flow. In addition, as your oil filter filters out some of these suspended Teflon particles, your filter flow rate will be reduced which may eventually become restricted and default in to by-pass mode, which means unfiltered oil will be flowing through your engine.
Ever get bleach on your fingers? It's pretty slippery isn't it? Same principle here. Add enough Chlorinated components to a carrier and mix it with some type of teflon, moly, zinc or phosphorus & you can reduce the friction, except for one "minor" thing: Chlorinated additives mixed with oil and subjected to heat forms hydrochloric acid! Hydrochloric acid is extremely detrimental to you internal engine parts. Get the picture? That's it in a nutshell.
Bottom line is: When using a properly formulated motor oil you do not need any additives whatsoever and additionally, the additives you may put in can react negatively with the additives the oil company carefully blended in. Do yourself a favor and stay away from aftermarket oil additives, regardless of how appealing the bogus claims they make in their advertising are!

What if They Have a Test To Show How Their Additive
They put every type of oil on the market, one by one, on the machine & pressed hard on the torque meter and at about 20-40 lb-ft torque the torque arm would stall the motor....that is until they cleaned it off & tried their (chlorinated) additive "IXL" on the bearing & ran the test.
People were amazed as the meter peaked out at 140 lb-ft. torque and still didn't stall the motor! We knew what was happening but many unsuspecting consumers were eating it up and standing in line to buy the additive!
The next day we showed up with some Head & Shoulders Shampoo disguised in an oil bottle & had the IXL additive people try it on their test machine. The operator was amazed as the motor just barely stalled at 140 lb-ft!
The operator says that's pretty good stuff, what is it? We said Head & Shoulders. He was quite embarrassed to say the least. Head & Shoulders has high levels of high potency Zinc in it that attaches itself to ferrous metals. Coke soft drink will do exactly the same thing. ZINC reduces friction and provides anti-wear protection and is present in most motor oils at a much reduced level. Now, would you put Head & Shoulders in your engine?
Additionally, the test machine was measuring EXTREME PRESSURE. Motor oils do not have extreme pressure additives blended in like gear lubes do.
Their is absolutely no need for EP additives in a motor oil. A gear lube would not stall the motor as easily because gear lubes have high levels of Extreme Pressure additives blended in, but do you think they would test their IXL additive against gear lubes? Heck no! They use motor oil....They are comparing apples to oranges & tricking you into buying their additive!
Please DON'T be fooled by oil additives!
