I put 8oz of Marvel Mystery Oil in my fuel tank and only 4oz in my engine oil. The lifters that were clacking went away and the performance "seems" to be better. Next oil change I will replace one quart of oil with one quart of Marvel Mystery Oil. This is recommended by MMO between oil changes. I still have about 3000 miles on this oil change so I may drain off half a quart now and replace it with MMO to clean any sludge and varnish that may have collected during it's 98K miles. Anyone else use Marvel Mystery Oil?

 

Sounds like you might be running oil that is too thin. How many miles on that car?

 

98k miles. Marvel Mystery Oil says at every oil change to replace 1 quart of oil with 1 quart of MMO.

Mar​​​​​​vel Mystery Oil (Wikipedia)
Marvel Mystery Oil is a automotive product of the American Marvel Oil Company, founded by Burt Pierce in 1923. It is used as a fuel additive, oil additive, corrosion inhibitor, penetrating oil, and transmission leak stopper and seal relubricator.

 

Yea, I am not a fan of MMO or STP or any of that stuff.

I ran 5W40 (5W50 in Georgia's summer heat when I knew I was going to push the hell out of the engine) in my Graphite when it had those miles on it. I gave up on 0W40 by the time it had 60,000 miles on it cause I could hear noises I did not like and with a hot engine, 0W40 produces as little as 3 pounds of pressure at 600 rpm. (Put an oil pressure gauge on that engine and you will never put 0W40 in it again.)

0W40 is just too thin, even MB recommends 5W40 and has since 2011. I only run 5W40 in my SE, it's at 54,000 now.

 

Ive run into the lifter tick a bunch of times and its mainly due to carbon/sludge build up in the lifters. Its just going to happen if your car has a ton of miles on it. Mine is at 226k right now.

My remedy was to clean out the engine with BG 109 epr, you'll need 2 cans for the oil capacity of our car. After that I switched oil from 0w-40 to liquid moly 10w-40 mos2. Its basically a high zinc oil and I add a can of BG moa for good measure. BG products are used by alot of euro dealerships from MB to even Ferrari. You cannot buy BG products in a store, you have to order them online from amazon or ebay. Usually, its the dealerships selling them.

I also agree with pizza, 0w-40 is just to thin a oil, its damn near water.

 

I bought my CF back in November and the oil had just been changed. The seller was using the 0-40w oil and I think next oil change I'll switch to 5-40w. Next oil change is 93,000 miles. I was wrong about how many miles is on my car. It's actually 90,520 and I had confused it with my truck which has 98K miles. Maybe next oil change I'll only go with 1/2 quart of the Marvel Oil. The lifter ticking has gone away with only adding 4 ounces to the oil a couple of weeks ago.

 

I think people should read about SAE viscosity, how it is calculated and what it means, I do agree that 5W -40 is OK.
The oil has to be thin enough to get into areas where the gap is small, and not get squeezed out under load.
Clapped out engines excepted.

If oil enhancers were worth anything then the oil manufacturers would have added the same chemicals when refining their oil just so their oil was that much better.

Putting an STP sticker and the like on your car identifies you as a sucker for snake oil ads. 😉

 

After reading several articles I found out that it's about a 3w oil and has several benefits. Being the engine oil capacity is about 8 quarts it is recommended to replace 20% of oil with MMO which would be 1.6 quarts. So next oil change I'll go at least with only one quart of MMO. I see they claim it would remove varnish and other engine build-ups as well as providing moisture inhibitor values . Piston rings, especially oil control rings, benefit by it keeping them clean. This is not the first time I've used MMO over the years and have had successful results.

 

"For what's it worth." I removed 1/2 quart of oil and added 1/2 quart of Marvel Mystery Oil to the crankcase. Also added to gas tank at the recommend amount. I've driven about 1000 miles and have had positive results with engine noise and seemingly smoother engine performance. No more lifter noise. I know the purest collector doesn't like additives but I've had really good luck with some of my older cars in years past. Especially ones that liked to smoke from possibly clogged / stuck oil control rings.

 

So I was reading through these post and decided to add MMO to my engine and gas. 3/4 quart in oil (drained 3/4 quarts) and 3 ounces in my tank right before I put 10 gallons of premium in. My car lost a ton of low end torque. My take offs were slow af. My car seemed to drive smoother... but either I was paranoid or it sounded just...tamed down. I just did a oil change with 5w40 and decided it was a bad idea. It may of just been it diluted my 93 gas down too much, idk. Just felt like sharing.
OH and can we make it a know thing that 7 quarts of oil is what fills our cars up not 8!

 

Oh no it's the dreaded discussion of how much oil capacity the engine takes!

 

You joined up four months ago and you are telling us how much oil it takes, we know the real answer and it is not what you say.
This forum is going downhill fast, I give up. We have a bunch of know it all’s joining and they give false information either intentionally or not.
I will only answer old members from now on.

 

It’s nice to be important but more important to be nice

 

And someday when all the old members have been replaced by new members you are going to be very alone with a wealth of knowledge you could share but choose not to. Maybe you don't care though. No matter, the new members will gradually figure these cars out on their own without your help.

 

It has basically been worked out, all you have to do is search. The oil capacity was settled in the first year.We are getting bad information given as gospel, that does not help anyone.
You have to be careful what you take as being the truth on any subject, we already have bad info here, hopefully it has been corrected in the same thread.

 

are you being a whiney old man over a half a quart? Damn dude you need to spend more of your time enjoying your life instead of nitpicking everyone's posts on here. Maybe correct me instead of showing this whole forum how miserable you are.

 

Half a quart? It is a least eight quarts not seven a half, or in reality eight liters. You just have to drain it properly.
Get your facts straight before criticizing others.

 

onehundred80, Just ignore him and let him believe the 7 quart theory. Everyone else knows better.

 

Zeracer, you are right. 180 is an acquired taste but the forum is much better off ever since he joined and still is to this day.

The forum would be better if some of these new members never found it. The forum is so well indexed on Google, we get people with other cars asking for help! lol

 

Yes this is my old thread but would like to know if anyone has used Dexron 3 transmission fluid, at oil change, to clean engine components especially ticking lifter? I watched a video where mechanic added it to his Dodge Hemi at oil change. The truck had 300k miles and lifters were really noisy. he drove the truck for 200 miles and updated the video to show the difference between before and after results. The engine was really quite! My '06 has 98K and has a worrisome tick ever since I bought it in 2021. I added, when I bought the car, 1/2 quart of Marvel Mystery Oil to the engine and ticking went away for some time. Couple days ago I did another oil change. I don't believe it would damage anything and wondering if this was worth a try. If interested the link is here to view the video.
