lol mine hits at least 5 once a week. I drive it normally pretty much all the time though. I need to try some of this motorcraft stuff, kind of hard to hammer on it now with MT's

 

most areas that have the build up would have been cleaned/replaced with the cylinder head work.

To me, the time to do this would be in conjuction with a plug change. Its seems the mileage increment for doing it would be similar.

I did my wifes 03 Thunderbird over the weekend. It was a lot different than the 6 cylinder on my truck. It injested 1/2 a can. I let it sit for 20 minutes, then started it up and put the rest of the can in.

I asked my wife to go drive it hard 3 miles down the road, then come back.

No smoke until after she backed up, turned right out of the driveway, then mashed the gas pedal. She left an 1/8 mile trail of smoke. lol. My truck was smoking hard while at idle.

Not sure the reason for the difference. The thunderbird gets "hammered" more than the truck so there may be less carbon in there. Not sure.

 

As i said in my other thread.

I've seafoamed my truck w/ no result but some smoke, yesterday I went to visit Wayne and we put some of this PM-3 into my truck and the horrid tick is gone!

 

ok i just done my oil change recently and i wanna try this stuff out. Has anyone done it and not changed their oil?

 

i did on two trucks, youll be ok...if you do it 3 times like the tsb says, change it

 

im gonna pickup a can tomarrow instead of seafoam !

 

I'll be ordering this when I order my roller rockers :D

 

does it improve mpg or just clean carbon?
