Wow, what an incredibly helpful and well thought out post. Thank you for sharing your obvious incite and experience.

Since these Dodge truck engines are some of the worse designed and faulty engines out there, I doubt the Slick 50 can hurt them. Because they break down so much, who's to say it was the oil's fault; maybe the Slick 50 is just a scapegoat? The reality is these engines break for no reason, at any time, no matter how well kept they are...this site is living proof to what POS they are.

I have used Slick 50 in MANY cars and never had a problem with them...in fact I always saw a slight increase in mileage and they ran quieter. (No, I am not associated with them in any way.)

Answer me a single question...How many times have YOU used it and had it be the proverbial "death of you engine"?

 

Do you mean "insight"?

False. You don't know what you're talking about. Ever tear down a Magnum engine? They're based on the old "A" series engine, and are damned near bullet proof. Like the old Straight-6, this engine can literally run on a quart of oil with no ill effects probably because of the large hole cast to the front of the lifter gallery, allowing oil to fall back down to the pan. Any engine failure (ie sludge build-up) would be due to negligence in proper oil changing intervals. Again, based on your comments, I doubt you've ever turned a wrench, and instead look for a cure in a bottle.

If you care to exert some effort, do some reading:

Slick 50 (engine oil additives)


It's like the transmission fluid additives. All they do is make the seals swell and temporarily "fix" the transmission, and then BLAMMO.

Do some more reading and you'll see where people have sued because Slick 50 actually caused their engines to fail.
