Tcw3 as upper cylinder lubricant?

[ziggy]

I won't do this no more! I used tcw3 super tech,and valvoline 2 board believe it is, bottle says tcw3. 18 gallon tank. Did my research here believe I was adding 3 ozs too quarter tank or in-between empty quarter tank . One night few years ago, car turned off driving . Started ,it turned off many times.
Had it towed 98 Buick LeSabre.
Mechanic dropped tank. Their was oil in the gas he said. I told him my tcw3 treatments.. he said no more .just gasoline Jason .just gasoline $5-$600 bill, had too replace spark plugs too,they were coated in the tcw3.
No I
More....I use lucas ucl .

As chrisD246 said..every 3-4 tanks, gas only .so any tcw3 in dosn't accumulate so it costs your spark plugs,so car turns off driving....as mine did..that's what I did not do..

I tried this years ago in my Escape and although not scientific I felt it did run smoother, quieter, and got slightly better MPG. But who knows if it wasn’t placebo and I was using the MPG thing on the dash which isn’t perfectly accurate anyway.

3oz to quarter tank what's the ratio on that? And people saying tcw3 burns clean etc, guess it's just to risky to do this

 

[ChrisD46]

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

I experimented in a small Hyundai Elantra 2.0L non - turbo engine which ran better at 900:1 TC-W3 ratio than it did on 640:1 ratio (gas mileage was better too).

You heavily overdosed the TCW-3. I've been using 1:600 for more than 10 years in all my cars and have had absolutely no problems with this mix. Visually, after thorough mixing clear two-stroke oil with the gas in this ratio in a clear container, I cannot detect any evidence of the oil now in the gas. Your mechanic saying he saw oil in your gas says everything. On routine spark plug replacements, I don't see anything unusual on the porcelain insulators.

And if you've been using Lucas UCL, it needs even MORE gas than TCW3. Recommended is 3 oz per 10 gallons.

Wouldn't high dosage cause hydro lock?

What is the reason you began doing this?

I can see on a oil injected/ fuel injected 2 stroke for adaquate lubrication , but dont see the automobile benefit.

 

[berniedd]

No. The oil-gas mixture still atomizes. In 2-stroke engines, the oil in the fuel (even at 1:80) does not burn off completely. This is intentional, as that is what lubricates the moving parts. Hence the visible blue/grey smoke and deposits because combustion isn't perfect. Some oil always remains as a film, gets partially washed away, or exits unburned, leading to emissions and carbon buildup. This remaining oil fouled up your spark plugs.

I believe there is benefit in providing more lubricity esp for the upper piston rings. I read of a post by a mechanic that adding TCW3 consistently raised compression ratio by 5 psi in his measurements. Small, but detectable. But is it significant? IDK. Also I believe it improves E10 gas like Stabil does, by lessening ethanol's negative effects like corrosion, gumming, and fuel breakdown, preventing deposits, and keeping fuel fresh for longer.

Is that with regular 2 stroke oil like Jaso FD stuff or does tcw3 also leave carbon deposits that foul spark plugs?

Regular 2-stroke oil and TCW3 have similar functions for engines. Usually in 1:50 or so dilution. But they are not the same formulation. Regular 2T oil is designed for air cooled high temp engines (such as motorcyles) and TCW3 is designed for cooler running water-cooled (usually boat) engines.

Wouldn't the high temp air cooled oil be of better formulation then?

The reason that TCW3 was chosen as an upper cylinder lubricant is that it's ashless. If you are going to deliberately introduce oil into the combustion chamber you want it to burn with minimal deposits. That's the aspect of formulation that matters in this application.

What benefit does ash have in oils that use ash?

 

[wag123]

What benefit does ash have in oils that use ash?

Ash content refers to the metallic anti-wear additives (such as calcium and zinc). Ash acts as a cushion to reduce metal-to-metal contact between the hot valve faces and their mating seats in 4-cycle engines. The ash does not burn-off and can/will cause deposits which are detrimental to 2-cycle engines.

If you want something that works just dump a half quart of Atf in the tank. It won't hurt the cats and it does wonders for carbon build up and fuel injectors. People have been using it this way for years. I actually got to see the results first hand when I blew a head gasket at a couple hundred thousand miles on my Grand Cherokee. The combustion chamber was clean like it had very few miles on it. The head gasket blew from overheating. I let my secretary use it for a couple months and she said the quicky oil change guy popped the radiator cap because he didn't know any better plus she kept drivng it hot because well it wasn't hers and she didn't care.

 

[GSCJR]

When head gaskets fail, they clean piston tops very well. Are you sure it wasn't a cleaning effect from the coolant?

 

[oil_for_my_doo]

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 agree. The LSPI problem was solved by reducing the Calcium additives in the motor oils. TCW3-certified oils have zero metallic additives so its a non-issue.

Not LSPI but I found dosing with TCW3 eliminated mild detonation and pretty much straight away so it can't have been the cleaning effect which did also occur after many years of use.
