I been trying all kind of products to stop the noisy lifters on my 03 lightning,a friend toll me about the MMO I’m about to try MMO to see if works, it’s my last shot before I open the engine.About how many oils change with MMO would it take to quite those noisy lifters I’m tire of that noise specially on the mornings, my lightning have 83000 miles on it.Any advice or tip will help and thank you for your time.

just run a 5/30 instead of 5/20. thats what i did

I talk to a mechanic and told me to stick with what factory recommends,but I’ll try 5/30 with MMO and see whats happens after that thanks electrolover…

depends on the noise.

Is the noise only at “cold start” or is it constant?

If it’s only at cold start, it could be the oil may be too thick and isn’t traveling quick enough, so the “noise” you are hearing until warm up is metal:metal contact, until the oil gets to where it needs to go.

Other instances, I’ve heard of some oil filters simply being “noisier” than others....lol.  I had some noisy orange FRAMs, changed them out with Champ Labs “SuperTech” filter, and the noise went away....

On another vehicle, ran 5-30 dino oil, always had a noise on cold start.....so I added Seafoam (before I was educated of MMO and it’s benefits) to the crankcase per directions, and the next morning (cold start) - no noise on startup

Some speculation:
Either it cleaned up something and got rid of the noise.

Other speculation @ BITOG forums, the Seafoam “thinned out” my oil, so it got to where it needed to be quicker..

Well,BUGS I’m been using 5w20 mobil oil and mobil oil filter and sometimes I use k&n;oil filter and also I was using 1 qt of lucas to stabilize the oil,but right now I have royal purple oil on it with royal purple oil filter with no lucas on it and the noise it’s little louder now.But I just bought some MMO and the truck still have to go 1500miles for the next oil change and I let you guys know what happen,thank for your tips BUGS........

if you have been adding lucas and the noise has not stopped it might not. maybe mmo will clean it up..
oh and you dont need to “stabilize” a good oil! lol lucas just thickens the oil. i would not add it to any good oil

A good quality group 4 synthetic oil like Royal Purple doesn’t need any additives at all. Run a regular dino oil with MMO to clean it out and then go back to Royal Purple with no additives.

Thanks Orangedotfever for the tip,I’m doing my last shot to get rid of the noise from ever morning before I open the engine........

Definitely agree with that.  I don’t think I’d ever recommend adding anything to synthetics.....even if they are “compatible” I generally only like using additives as a “clean up” phase.....and then let the good synthetic finish up the rest and keep it clean

Right now it’s in the process I put a 1qt of MMO in the oil 4 days ago and waiting to see what happens thanks guys........

NO NO NO NO NO NO. NEVER RUN OUT OF GRADE OIL. The engineers know what they are doing.

AND NEVER EVER EVER USE LUCAS OIL STABILIZER. There were tests done on it a long time ago and all it does is cause your great engine oil (Mobil 1 or Royal Purple) to foam up. Terrible, terrible stuff. You might as well pour water into the crankcase.

yea, I dont know about Lucas Oil “Stabilizer” - though I like playing with their displays at advance when I stop in.....lol.  Funny how if you spin that little handle REALLLLLY fast, you will start to see bubbles/foam on the Lucas side

On a side note:
perhaps Marvel could create a similar display.....?  Pretty pweeeze?

Well right know I’m running 5w20 royal purple oil with royal purple oil filter and 1qt of MMO and the motor still have to go 1100 miles for the next oil change,I’ll keep u guys updated of what happen next if it works or not.Thanks Techniker and bugs.......

THE ENGINEERS SAY NOT TO USE ADDITIVES AT ALL!!  what do you think a 20w thinns to with mmo? too thin if you ask me. btw i have 20k of 5/30 use in my truck with no ill effects

My truck still have to go 700 miles for the next oil change,but no sign of quite lifters...Electrolover I use that oil because thats what factory recomends for my truck 5w20 and I know sounds too thin,but thanks for all the tips and time guys......

has it been noisy like this since you got the vehicle?

sounds like you may be “out of luck” with any mechanic-in-a-bottle.......may consider looking for other lightning “enthusiastic” forums around the web, and see if anyone else has experienced similar problems.....
