My lifters in my car get very noisey someone said to use marvel mystery oil i have herd allot of good things about it when i used to work at auto hell. Any wyas do i put this in my oil after the oil change like i would with dura lube or do i put it in before the oil change like i would a engine oil cleaner? Also it says i can put it in my gas tank to clean my fuel pump/carburetor im not gonna put it in my gas but is it really that versatile. Any one ever use it before.

 

yup and yup. oil and gas.

 

Lots of additives are very harsh but MMO is good for your in-tank fuel pump.

You can add either at any time. You don't "need" to do an oil change. Do it once before and after, might help clean the gunk out of the lifters better. I buy a mini bottle ever now and then and throw it in the tank for good measure.

I know plenty of old guys who do that at every oil change, add it to the gas n oil and it works well. I do know that when they find a motor from the 1940s sitting in a field rusted shut for 50 years, they soak the whole motor in a vat of MMO for 6-12 months and it strips it clean. It will look just like the day it was parked inside the motor.

 

If that don't work, try adjusting your rocker arms until absolutely NO slack in the arms themselves exists, and tighten them with thread locking compound so they will keep the same setting for a while. The arms like to get loose and develop side to side play. It is a little bit of play, but that will make a heck of a noise when the engine is running.

 

i have like 230,000 miles i feel if i start messing with stuff now it will cause more problems later on. so i should pour a little bottle in before i change the oil then a normal size bottle in after i put the fresh oil in

 

Yes, I used MMO when my lifters got very noisey. I put about 1/2 can in my oil, started it up, and they quieted down after about 2 mintues of running. I was never a beleiver of additives at all, but my mechanic buddy had suggested it when the problem crept up. But MMO certainly does work.

 

Here is some interesting info on oil additives:

Also, here is some good info on oil itself, and viscosity indexes, flash point, pour point, % sulfated ash, and % zinc numbers for many different engine oils.

Here are some general lubricant notes by RedLine (good info):

If its gonna go in the direction you can beat

do one better, mix some lucas and whatever oil you use in a small container to lucas's recomendations (1/4 lucas 3/4 oil) then put the container in the freezer and let it sit a little bit, take it out and youll see the crap you get in the bottom of you oil pan when it gets freezing outside!The crap is like bubble gum. But MMO is a bit thinner than lucas so its not a fair test.

 

Well, the stuff is supposed to quiet noisy pistons/rings/bearings/lifters, right? Well, I put a full quart of MMO in the pan along with 3 qts of 10w-30 the last time I did an oil change to mom's car, and either it is more screwed up than I thought or it don't work. I have also tried that blue Rislone stuff (another additive designed to quiet lifters) and that didn't work either, it just made more of a hassle (fixed by a proper valve adjustment). Has anyone ever seen that Lucas oil stabilizer when it comes out of the bottle? It looks just like honey (if it is anything like High-Tach), and I don't think it is helping my cold weather starting much....

If your lifters are so loud that only revving the engine at 3500 RPM w/ or w/o the exhaust pipes disconnected drowns out the noise, then the valve adjustment is needed....

 

If it ever froze in southern cali i would be shocked. My mechanic was the one who recomended using it. When it is cold outside i dont hear the lifters but once the car is warm and it warms up you hear the lifters like no tommorw.

 

A full quart is too much. When you do an oil change you buy a quart but half goes in the oil the other half goes in the gas tank.

 

How'd you figure that out? That's what the bottle says to do. I read it before I bought it. Also, how would I find half a bottle of that stuff?

Also, Fast RS, it sounds like you need to use a different oil. Whatever you are using thins out too much at higher engine temps, so much that the lifters are affected.

 

i know a ton about this stuff. First off

MY dad put about 4-6 oz in his 80 gmc pickup up every gass fill up for about nine years when he sold the truck a few years back he decided to rebuild the carb b4 he sold it opened her up and it looked like it had just came from edelbrock it was spotless inside. WE put it in everyone of our cars every fill up and i love it. we pulled my tbi apart about a few weeks after i got the car before we could see crap down near the butterflies i ran probally 3 tanks full of marvel and it was clean. WE put a few ounces in the crank about a week before an oil change and the oil usually turns dirtier from the crap gettign cleaned out. Definately give it my approval:hail: :hail:

 

ok how exactly does putting mmo in your gas clean near your butterfly?

 

He's talking about the throttle plates in his TBI, br()bert... those types of valves are also referred to as butterfly valves in the technical world...

 

I know thats why i dont understand how adding mmo to your gas would clean that part since gas doesnt(or shouldnt) even be near that part.

 

so i should run some before the oil change

 

So i should run some before the oil change to clean the crap out and then put the rest in after i change the oil? im running 10-40 max life i wana bump up the weight tho but i cant say no to 10-40 max life 5 qts for 10 bucks the store also had mobil 1 syn for 5 qts 20 bucks it comes in one of those big jugs insted of in normal bottles. isnt there a 20 40 weight or is it just 20 50 my car hates 20 50

 

MY understanding of TBI is that it is a simpler form of the carburetor (fuel injector system instead of mechanical linkage) in which the fuel comes BEFORE the plates, which control the flow of BOTH fuel and air to the cylinders.

And FAST- buy a quart and put roughly half in the gas tank and half in the oil pan and run it for a while before the change. Don't use MaxLife: it conditions the seals in the engine for roughly 10000 miles, and then they go back to their previous state or worse. If the engine don't like 20W50 then stay with 10W30 (10W40 is no longer approved for automotive use according to some sources I have read) and throw in a bottle of Lucas or the rest of the MMO. Go to WalMart-I bought one of those four/five quart bottles of Valvoline 5W30 and the MMO for less than $15, unless you like running synthetic.

 

i have used max life sicn e my car had 160,000 miles on it now it has 230,000 i dont wana switch oils on its last legg

 

DUH, i tottaly missed the tbi part now i understand what he ment.Instead of lucas in your oil you might as well throw some sand or rock salt in it as. Itll have the same effect as the lucas will. Esp if you live in a cold climate. Lucas makes your oil WAY too thick when its cold, plus it doesnt resist air bubbles. And 10 40 is fine.Everyone i know uses it here.

 

Well maybe I'm thinking wrong but the big steel can that is the best deal. Not sure how much is in it. Half goes in the tank / half in the oil. [ is what recommended by them old guys]

i buy the $2 bottle for the tank ever so often, might be a pint.

I would think a full can might be too much. Myself I run my oil about 1/2 a quart over full anyways, so the pan is full running with oil in the top of the motor.

 

I bought the stuff in a opaque (not see through) red plastic bottle as a full quart. I think I'll try that though for next oil change... Have to get that gas out of the crankcase!

 

I agree, once it seemed to work, my skepticism quieted down.

 

I finaly pu tit in my car a week ago it made my lifteras extreamly quiet after wards im sold on this stuff. Im gonna use it every oilchange. It actualy smells good to it has a werid minty smell to it. It not think at all its actualy thiner then oil. And is red in color. Wal Mart sells a 1 gallon jug of it for 9.00 So next time im going to buy that. FYI walmart sells 5 gallon jugs of mobil 1 syn oyl for 20 bucks. 5 gallon jugs of max liffe for 10 bucks its wayyy cheap there. Just a little hint on good yet cheap oil prices
