For those who swear by it, what's the recommended dose of TC-W3 per tank full ??

Better make it stronger than 50:1. Why? That's what's in yer weed eater, right? How does it start in the spring?

I run 2 oz / tank. If a bike is gonna sit a good long time, maybe double it, but that's alot.  I will say this - my bikes sit in a steel building in the summer in Florida, and don't get ridden much during the summer. Ethanol evaporates at an alarming rate, and in just a day or 2 I would need to use  prime to refill the bowls. On the voyager it goes from insta-start to cranking forever to fill the carbs (fuel pump). Pre tcw-3 I was having carb issues. i actually had to pull shoodabens carbs after a 6 week layoff because the pilots were clogged hopelessly. Since the tcw-3 I have has ZERO issues. I know older guys used Marvel Mystery oil the same way, and tout the same advantages. JMO, Steve

2 oz. per tank kept my connie starting and running fine. Backin Steve up on this one as I had the same experience with my bike.

Thanks chaps. I've been through one bottle at about that 2oz/tank dose, and have just bought a second bottle. My bike doesn't sit much more than a week, and I'll ride through the winter as much as I can, but I am virtually convinced it helps anyway...

Seems to me it helps to lube the carb slides, making roll-ons and roll-offs between 2000 and 3000 smoother. Could I be right, do you suppose, or is it my imagination and wishful thinking?

I can't offer any real proof, but I agree that I think it helps. It certainly doesn't hurt them.
I rode year round here in arkansas and never had more than a week or two in the winter that it sat. But with todays crap they sell for gas, that was enough time to cause a problem if I didn"t have the oil added. And in the summer heat it took less than a week.

So why do chain saws and weed eaters have problems?

Poor design, probably. The carburetors in those things are hardly top grade designs, and the slightest imperfection would be likely to cause problems.

Just my expressly uneducated opinion.

  I don't do chain saws and weed eaters - to lazy, I pay someone - but I've been using tcw3 for a few years in my pressure washer, and it has looong sits. never fails to start and runs like a champ. I have to admit though, it's a honda    Steve

I'm not having any issues with the weedeater or lawn mower I use it in. 

Or maybe the carbs in the weed-whackers and saws are better designs than motorcycles. - ??

I have a Sindawa 25 brush cutter, 2 Stihl saws (029 and 170), cheap-a$$ MTD lawnmower, and Generac 3.5K generator.  Except for the mower, all are 18 years old and all start with two or three pulls of the string even after sitting all winter.  The fuel in the Generac is from 1996, sitting in a damp cold basement and it starts and runs just fine.  I don't use tcw-3, but I do use Stabil in the Generac, the Connie and the Wee-Strom.

I'm intrigued by all this.  I use Stabil and have had no problems in the snowblower, weed eater, street bikes, dirt bikes, pressure washer, lawn mower, atvs.  It'd be cheaper and more convenient for me to throw in a few ounces of 2 stroke oil, but does it have to be TCWIII specifically or will Castol Actevo Snow 2T 2cycle oil for snowmobiles work?

Another question - I wonder why Toro sells their 2 cycle oil with "fuel stabilizer added"?

No wonder, carbs made by harley could never be top grade.

Just about all the small engine shops around here sell pre-mixed fuel and highly recommend it. They say the majority of their work is carb work. Co-worker swears by it, says it has a long shelf life.

I asked the guy that runs the small engine shop (teaching inmates how to fix and rebuild them) at my prison a few questions earlier this year.  He suggested using premium gas.  (Ethanol free not available anywhere near here.  And how much more does the premium really cost in the amounts you use in small engines?)  But he said that even the premium gas here in NY wasn't great.

I had asked him about my line trimmer, which wouldn't run, except on half choke.  Even when new.  He said that the EPA settings (unadjustable) on the carbs, and the crappy NY ethanol gas both contributed to it.  The solution:  Keep running it on half choke.

TC-W3? Brand name or ?? I guess it's a fuel stabilizer, right? Been using Sta-bil; any advantages to TC-W3?

Thanks,

It is a specific rating/specification for two-stroke oil.

I use Lucas TCW3 and put a cap full in every time I remember that I just filled up...around home, anyway...
