I have to take the truck back again on a day off from work after I order the antifreeze online, I will ask him then if he still has the picture but that might happen in a week or a month or even 3 months from now. If I take it soon I wont forget and I'll ask him to send me the picture, I'm sure...

The mechanic took the picture, I didn't even spoke to him regarding me being concerned how the engine looks on the inside. Its him being shocked of how clean it was after 21 years of me owning it its what compelled him to take the picture and showed it to me, I don't have the picture

there is zero weird engine noise and literal zero blow by when I unscrew the oil cap and leave it on top of the opening, actually the cap wont even vibrate at all from the engine working

Interestingly enough, what are the symptoms of stuck piston rings? loss of power? engine sound as if working harder than usual? burning oil noticed trough the smoky tail pipe? I have none of those symptoms, maybe you can pitch in other typical symptoms for stuck piston rings?

That might be the case that the VRP is marketed only for cleaning carbon buildup specially at the piston rings area but we can see people reporting that is doing more than just that, like removing sludge and slowly removing varnish too. Next oil change I will introduce 1 quart of the Valvoline...

Question is considering both valve cover gaskets were changed and the oil pan gasket too and the engine looks spotless top and bottom, where else can there be sludge hiding? I know the concern is always around the pistons area because that's where the magic happens but lets not forget that is...

This is little bit late me replying here considering I was interested in trying out Valvoline since my truck is 21 years old with 205K miles on it. Well I had some maintenance work done on it this past month and we did it in 3 stages because was too many things was due for maintenance like spark...

Nice to know you had a good cleaning experience with the Valvo, after how many miles was the oil change done that you experienced the filter clogging? Did you notice power increase or snappier and more responsive engine after the drivetrain was cleaned up a bit?

I will give the Valvo a shot on the next oil change, but if I dont seen the oil darkening after couple hundred miles it means my engine is not dirty even after 20 years/205K miles on it. Like I posted before I had a shady 7-8 oil changes 40K miles pass the 140K mark and still every time I look...

When you say not a long drain oil you mean change the oil on shorter intervals, maybe 3K miles per oil change as Valvoline stated 4 oil changes back to back in case if the engine has carbon build up correct? Do we have actual proof amongst users that have experienced this when they switched to...

I barely found the video men... Here it is its an old video it does not refer to the EP version but their annual protection version however all their oils are tested the same way. I don't need anyone to tell me how good or bad is the Mobil 1 EP line line of oils, my F150 is 2004 (20years) and...

I know what they claim, do we have actual results of pistons being cleaned squeaky clean as they claim from a dirty engine?

VPR - Valvoline When I referred to the Mobil 1 EP is for the extended performance, they were testing their oil in engines under harsh conditions with polluted gasoline and out of specs piston rings and metal to metal wear passed the test including the cleanliness of the pistons and the rings...

So guys what's the verdicts regarding engine cleaning when comparing the VRP to lets say the top tiers of the rest of the brands such as Mobil 1 Extended Performance or Pennzoil Ultra Platinum or whatever Castrol top tier offers. Is it really that much of a difference, or are we speaking maybe...
