Lubricity Additive Study Results

I found this old study in old forum. Does anyone know if there is similar study for gasoline engine? mostly one include MMO and TCW3 that are highly touted in this forum.

I have used MMO and TCW3 (pick it up in this forum) in past few weeks and enjoy the results.

My experience started with MMO. I added 3oz per 10 gal of gas to start with and after driving about 50 miles, I noticed my engine was quieter and vibrate less. It felt like going from 4 banger to V6 all over again (had 97 Escort before). On that trip I happened to get 37.1 mpg on hwy round trip. That was the best I've ever gotten where second best was 34.2 mpg. I haven't taken long trip since then. So, it was only 1 straw, not a long time averages.

Then in this forum too, I found TCW3 in gas engine 3 weeks later. Oh boy, it took it to another level of smoothness. I started with 1 oz in 5 gal, then now 1 oz in 4 is even better. There was 1 time, I forgot and only put in 1oz to 5gal, I noticed the vibration increased. Next time I'll try 1 oz to 3gal and see what happen.
 
Holy $**!. 1 oz of Tc-w3 to 5 gal.! That is the most I have heard anyone use. You have to be careful my man...too much of a good thing, well you know. DO NOT USE THAT MUCH TC-W3 UNTIL YOU LEARN MORE ABOUT IT!
 
A little off topic but you might need new motor mounts if the vibration is felt. While the V6 isn't an inherently balanced engine the vibration on a properly counterbalanced one should be minimal. Every V6 I have driven has been vibration-free.

Also, don't consider the 1997 Escort to be indicative of inline-4 vibrations; the CVH engine in that car is far above and beyond awful. The engine was so bad there's a play on the engine's acronym to be "Considerable Vibration and Harshness". The fact that they kept it in service until 2004 is just beyond comprehension.
 
I use one ounce to 5 gallons of gas when I use TCW3. Be careful as Chubbs said. TCW3 will foul plugs a lot easier than MMO will. I've added a qt of MMO to the gas in my son's BWM before he deployed and didn't foul plugs, the same dose of TCW3 would probably cause problems. I'm not about to try it to find out.
 
I'll keep an eye on my plugs and scale down a little bit. I just love the smoothness of the engine and wanting more.

I read the post in LS1 web and found few people use 1 oz to 4 gal and very few use it to 3 gal. Although rule of thumbs was still at 5 gal/oz.

As far as vibration, it was a normal one, not an excessive as if you have a bad mount. No worry there. Had I have hybrid, there won't be any vibration at all.
 
As you noticed, good 2 stroke oil IS slipperier than MMO.
Like the guys said, don't use as much TCW3 as MMO in the fuel.
Your in the right ballpark .


It's simple. MMO helps lube things, and is a cleaner.

2 stroke oil is a better lube, but is 'dirtier' [not a horrid problem unless excess is used].

I use both, but am using MMO a lot more lately.
 
Just out of curiosity. I believe TCW3 is ashless. Then how is it fouling the plugs?

Also, I wonder where to get the cheapest MMO? My local wally only sells 32oz for $4.67 and they don't have the gallon jug which I heard supposed to be about $13.
 
TCW3 is MORE ashless than regular air cooled 2 stroke oil.
But not immune!
And plugs foul not because of ash deposits, but an actual coating of oil on them.
It take a LOT to actually foul a plug.
Some note that the combustion chambers and parts of the plug are dirtier, not really fouled.

It's an ashless additive (no hard metal based), so it won't coat the cat. Plus, this additive is use much lower than typical 2t engine, at about 1/10 of 2t engine or 1:500. As far as study, I'm also looking for it.

I doubt you'll find one. TCW3 was never intended to be used in 4 stroke automotive engines as an additive to gasoline, so I doubt anyone is going to pony up the $$ for a study. TCW3 is another example of people thinking out of the box and trying something different. Lots of good info about it on the LS1 forum, some here but that's about it. As with the Internet you'll have to sort through the info and make an informed decision based on what you find. I tried it, and felt it was better than MMO at improving idle quality in my 200K+ mile Aerostar, but opinions and observations are worthless to many people here. People looking for factual data should stay clear of TCW3 as a fuel additive in a 4 stroke engine. I will continue to use it though factual data or not. JMO
 
Personal experience, and even vicarious experience, can be very factual and scientific.

2 stroke oil, esp TCW3, actually burns - like fuel.
It is not like motor oil when it burns. It burns much cleaner.
If cats can handle oil burners, a tiny amount of 2 stroke oil has proven to be no problem.

I know TCW3 is not meant to be used in 4t engine. Just like the study above, it was noted that the use of TCW3 was unconventional. As a matter of fact, in our use in 4t is much closer then the study above (gas vs diesel). 2t is meant to be mix with gas rather than than diesel. Therefore, I was hoping to find an independent study similar to the OP.

Hopefully one will turn up sooner rather than later. Keep my finger cross.
 
Some manufacturers such as GM stated that 1qt of motor oil consumed per 500 miles is acceptable for a new car (e.g. a Corvette). 1qt consumed per 2000 miles is nominal for regular passenger car, again for a new car. So, your 1oz per 5 gallons is not going to do anything to the cat according to the manufacturers. I did the math in the other TCW3 post if you care to search.
 
By trial and error, I have found that my cars respond better with 1oz TCW3 per 8gal of fuel. Stronger than that and I do not like the response.

One needs to experiment to find the best ratio for individual vehicle. The starting point should be 1oz TCW3 per 5gal and then adjust from there.

Agree wholeheartedly...

Where's the handshake smiley.

Does this mean that a non TCW3 Two Stroke Oil could be used?

Thanks, Jim
 
To Vikas's point : He is using 1024 : 1 ratio (1 oz. to 8 gal) . 1 oz to 5 gal would be 640 : 1. I don't recommend going below 640 : 1 ratio and for my vehicles using TCW3 , I start at 853 : 1 ratio and go up from there until engine smoothness / MPG are best . For MMO I start with 426 : 1 (1.5 oz to 5 gal) and go up from there until engine smoothness / MPG are best . I found the respective 640 : 1 recommended ratio (TCW3) and 320 : 1 recommended ratio (MMO) a bit too strong . * For those interested I use a nifty additive / gas ratio calculator here -> http://www.csgnetwork.com/oilfuelcalc.html . Works like a champ !
