    Slick 50 coats the internal engine parts and if there is a loss of oil it would allow some time to pull over and add oil to take it to the dealership or allow you to pull over and get the car towed without there already being major damage to the engine.
    No, it does none of those things. That is pure marketing BS.

    My boss (Advance auto parts) years ago was on his way home and he started hearing some light lifter noise from his truck engine. His oil pan had a gash in it from a rock hitting it and there was no oil left in the engine. Without the Slick 50 there would have been some major damage to the engine.
    I've heard of slant sixes being run to redline with no oil in them, and then being driven to the junkyard. The Slick 50 did NOTHING to save your boss's engine.

    Put any of those products in your engine and if Ford finds out your warranty goes bye bye.

    I hate to break it to all of the oil and additive experts on this forum, when you have a brand name "high mileage" oil it is their standard oil with cleaning additives added to it.

    This is from a Mobil 1 high mileage synthetic oil ad...

    Keep your older engines running like new with the help of High-Mileage Mobil 1 5W-20 Advanced Full-Synthetic Motor Oil. It is an advanced full-synthetic engine oil that is designed to provide exceptional wear protection, cleaning power and overall performance. This 5-qt motor oil bottle will support your car through oil change after oil change, helping to enhance and extend your engine's life. It does this by reducing deposits and sludge, protecting the parts in a high mileage engine. It also contains a seal conditioner to keep the engine seals in optimal condition and to prevent leaks. With excellent lubrication properties, Mobil 1 5W-20 Advanced Full Synthetic Motor Oil can be used in passenger cars, SUVs, light vans and trucks.

    This is no different than adding something like Marvel Mystery Oil to your regular synthetic oil.

    There is a difference between a brand name additive like Sea Foam and some off-brand gas station additive that claims it can fix for "broken" engine, etc...

    Do us a favor and go away. As you see most of us are not interested in your Slick 50. Or adding any additive just as the Shelby GT 350 supplement says. Theres enough having blown engines without escalating the chance of Ford not replacing it under warranty. Most of us use just what it says to use as far as oil and if theirs additives in that oil then were still covered cause thats the oil recommended to use. Troll your Slick 50 some where else.

    All I have done is given a suggestion and/or opinion trying to help. I have never said or stated that anyone should do what I said. For there to be insults and spam/troll accusations is not warranted of me or anyone else just responding to a thread. I will leave.

    Who am I going to believe? A petrochemical engineer, or a guy who worked behind the counter at Advance Auto who doesn't know Plastigauge from Silly Putty?

    Red herring. We're talking about oil additives, not fuel additives.

    Well I apologize for creating a ruckus. I spoke with Ford about what I have posted and had a tech ride along. They are not concerned about any of it. I had my first oil change. It was clean with no metal and less than 0.5qt usage in 3500 miles so I am quite pleased. I would like to note that with after the oil change, my hot idle pressure is up 5-10 lbs and it seems to knock less at the range I described. I attribute it to clean oil and having that 0.5qt or so being replenished.

    I have spoken with other folks whose hot idle oil pressure drops as their oil level declines. They replenish, pressure increases back. Sounds like a characteristic of the car to me. I can afford this car. I cannot afford to void a warranty on this car so I will NOT be using any products other than the recommended oil (or its equivalent for those amsoil fans ).

    Thank you to the senior members looking out.
