Rislone in the newer F150s?
Does anybody add Rislone when changing oil in their 2004 and newer F150s? I have been using Rislone for the past few years in my 1998 Voyager to help keep sludge buildup under control, however, I am not sure whether to start using it in my 2004 4.6L F150 with 36k miles. Any opinions on this?

It's possible they can deny warranty repairs to your engine should they become aware of you adding engine oil treatments. The best thing to do is use the motorcraft 5w-20 semi-synthetic oil and a motorcraft oil filter for your maintenance. Alot of posts have been made regarding this issue, and this seems to be the best advice with regards to the oil changes on these trucks. (this comes from a staunch user of Mobil1 full synthetic and Mobil1/Mann oil filters on all his vehicles for the last 10-12 years).

Hi guys, new to this section of the forum (I'll make an intro later)
Was searching for posts on Rislone and found only this one.
This morning, I went to see a trusted mechanic and he recommends Rislone for that knocking noise in our engines (5.4 3v)
He said it should take care of the varnish in the oil passage that lubricates the timing chain tensioner (which he thinks might be making the noise)
way to drudge up an old thread, i know i know.

Get yourself a glass of water and a clear plastic straw. Insert the straw into the glass of water. Place your finger over the top of the straw (creating a air tight seal) and remove the straw from the water. You will notice that there is water trapped in the straw. Rotate the straw 180 degrees while keeping your finger on the straw. The water will remain in the straw. Removing your finger will cause the water to flow out the entire length of the straw...
Your finger in this example acts much like a check valve. I also have one on my sump pump which prevents water from flowing back through the pump after it shuts off.

OOohhhh ok, so there is like a valve with a connecting passageway to the tensioner that mates up to the opening for the oil filter. I get it now. NICE. Thanks SharksFan and Air1Jpg for the help lol
I just couldn't visualize a connecting passageway lol sorry.
So with that, Air1, you don't think what my mechanic said is correct? Or his theory rather?
I'll search some more but what is the consensus on the knocking noise on these trucks? I read that someone took it to the dealer and the replaced a tensioner and some guide or something and the noise is gone.
And another thing . . . could it actually/possibly hurt the engine to put an additive in the oil?

Yes, it can hurt an engine to run additives depending on what they are. The additive package the oil manufacturer installs in their oil is all that is needed. If you are worried about it, follow the severe duty maintenance schedule. If you do any short trips, stop and go, or city driving, you are considered severe duty anyways as far as Ford is concerned.
