Tcw3 as upper cylinder lubricant?

[slybunda]

Been reading over on ls1.com a thread by sarge and a lot of other people where they use tcw3 2 stroke oil mix in gas at a ratio of 1:640 and have a good experience with better mpg and a cleaning effect in the engine with no drawbacks with benefits to lubing fuel pump and injectors.
What I dont get is that running this oil has to have disadvantages, can't just be all good from it I'd have thought it would foul up cats and sensors but apparently they say the oil burns clean so dunno.
I'd post on that forum but it's very unreliable and keeps timing out.
Surprised some companies don't just bottle it as a fuel system cleaner and profit big.
What are your thoughts on it?
At 1:640 ratio id be surprised if was just a placebo effect, it just seems to me to be too watered down to even have an effect?

Years ago I worked with a engine oil chemist who used NMMA TC-W3 at 1:400 for the same reasons that you mention.

Get Fuel Injector cleaner that lubricates.

I assume you are talking about adding 2 stroke oil to a 4stroke. 64 to 1 is a pretty high concentration for that. But yeah its going to splatter the cats with oil and valve stems, o2 sensors.

640:1 is a bit light but even then the injectors quieted some. I do about 350-400:1 most of the time. Noticeable feel in smoothness and the engine is a bit quieter as well as the gdi injectors being much quieter on my 21. In my old port injected trucks the old factory injectors seem to have quieted a bit but those aren't loud by nature. Tcw3 has such a low saps it won't hurt the o2 sensors or cats unless both were already on the verge of throwing a code by being so caked up from your existing oil consumption. But if it's not burning or at least much it's fine.

I use 1 oz per 5 gallons in my collector car and anything that gets filled from a jerry can. The car ran smoother at idle after a part tank. Everything else runs well with no downside that I have noticed. This is going on about 10 years now.

Any reason not to do this on an engine with a turbo? K20C4, to be exact.

I have dabbled with this as well. I run 1 oz per 5 gallons (640:1) I have noticed smoother idle and as a bonus the engine seems to spin over a little easier on those sub zero mornings.

whether it does anything for cleanliness is hard to put a finger on, also mileage. Not 100% sure it helps but it certainly doesn't hurt. Always use TCW-3 because it's ashless and wont harm the cats. You want to avoid oils with ash which is what you would find in oils designed for snowmobiles, chainsaws, dirtbikes, etc.

Also just to put things in perspective if you run a 640:1 ratio and average 25 mpg you will burn a quart of oil in 4000 miles. Any cat can handle that for 100's of thousands of miles as long as your engine isn't already burning a bunch of oil

I'm trying to wrap my head around how this could be helpful for a modern vehicle.

No honest reason. it shouldn't affect low speed pre ignition. tcw3 has nothing in it and it burns extremely cleanly unlike motor oil. if anything it should reduce lspi a touch. it does run slightly cooler but not cool enough to cause deposits. I changed the plugs on my V-Twin Kohler mower after running tcw3 for years and the plugs and pistons were clean and normal looking. didn't take pictures wish I would have but next time I will.

I'm not sure what you were expecting to see? You wouldn't want to see a bunch of things in an oil analysis for something you would consider burning in your engine

 

[slybunda]

Hmm wondering if this would be beneficial to those with a rotary engine?

 

[slybunda]

Another thing I don't get is that specs wise a jaso FD oil seems to be far superior to tcw3 when it comes to lubricity. Surprised people don't use that

Well premium gasoline is advertised to reduce wear and it appears to be true. They very well may put a tiny bit of oil in with the gas while making sure it maintains a clean burning 93 or 91 octane rating.
To quantify the effects, if there is any, it would take Lake Speed Jr levels of testing to measure any effect. Using things like test engines with those special rings that wear faster than normal.
Only testing I've ever done was on our old 4.6L crown Vic. An 8oz bottle of 2 stroke added randomly to fill ups did appear to increase fuel economy, but not enough justify the cost of the 2 stroke even if buying the Marine 2 stroke by the gallon from Walmart.
It was a blind study as it was my wife's car, she did almost all the driving in that car and didn't know about the test.

 

[slybunda]

Is it worth using higher octane fuel if car is not mapped to make use of it?

Yeah, being it’s an ash-less lube …
(non-metallic dispersants/detergents)

Isn't zddp supposed to be good?

It is popular in the rotary community.

It's also somewhat popular with guys running older diesels with the idea being that the older injection pumps were never designed to handle today's comparatively (dry) ultra low sulfur diesel fuel.

Standard rate is 640:1 not 64:1 … You can also use it at a little lower rate of say 900:1 as it is something you might have to play with to optimize improved MPG via increased engine compression / efficiencies . In a 16 to 18 gallon gas tank use 2 ounces at every fill up adding TCW-3 first to the tank then fill up with gas as normal . Every 3rd or 4th fill up with gas I’d skip the TCW-3 for a re-set (unless you only fill up your gas tank when near empty) . It works as well or better than Lucas gas treatment for the same benefits as Lucas gas treatment states .

I still don't get how 2 stroke oil so heavily diluted can actually have any effect at all. 640:1 is high dilution but 900:1 no way will it be able to do anything I would have thought
