Recently, with the advisement of another member, I started adding TCW3 to the diesel fuel in my 6.2 GM. To perhaps account for the "lost lubricity" of ULSD. I am confident that it will not hurt anything. Since adding the stuff, I have ran about 1\2 tank, and it is running and starting nicely.
Two-cycle oil Formulations
- Thread starter MolaKule
- Start date
Modern snowmobiles use power valves that change the exhaust port height. In my experience with them, they work great until the oil builds up a sticky layer, and they don't slide well anymore. All 2 stroke oils seem to do so, and between friends and I, I'm pretty sure that we have tried them all. Even though we don't ride Yamaha sleds, we now use Yamalube 2 sstroke performance.
Amsoil Interceptor is supposed to prevent exhaust valve deposits FWIW. I have used it and Dominator with great results.
After reading this very good discussion & great explanation by MolaKule, I went to see if Renewable Lubricants was doing anything with TCW3. Looks like they exceed that standard with whatever the oil make up is.
Anyone know what it is that makes it so different????
Could this possibly be a replacement for Lube Control or Fuel Power diluted in proper proportions!

i have run a commercial lawn care business for almost 40 years and have run my 2 strokes on 40/1 twc3 oil mostly. not one oil related failure in all that time
This was an interesting industry insider on TCW3 in addition to Molekule's writeup.

And these few mentioned products show how competitive the TCW3 market is : https://takeuroil.com/2-stroke-boat-motor-oil/
I wonder if HPL has entered that market?
I know its been mentioned about the HPL Gas Conditioner, & David the owner told me also they requested that it to have full spectrum coverage & every additive package "Jambed" into the forumlation, so maybe if is better than using it vs. TCW3 in gas, IF WE COULD JUST GET OUR HANDS ON IT EASILY!

I'm generally a fan of Renewable Lubricants, but dang, the above stuff is quite expensive. I bought a gallon of Pennzoil TCW3 marine 2C oil for $22. The R.L. stuff would have to work 2 to 3 times better than the former for me to consider it.
I wonder if they also use Antimony in 2 Cycle, & I read Antimony is on the sanctions list from China over the trade war as they are supposedly the primary producer of Antimony. When I read a news article mentioning this, a few months ago, I immediately thought of Renewable Lubricants & Schaffer's getting more expensive.

I think anytime Renewable Lubricants uses their HOBS in the formula, they have to use some antimony and/or copper as part of the stabilization chemistry for same?
I'm not sure, but I think that product has been fairly expensive for awhile. All their PCMO's and HDEO's have the HOBS and thus also some antimony and/or copper, and I don't think their prices have significantly raised recently.
They actually had a pretty significant sale on their 5w-30 PCMO a little while back (on the quart sizes). 3.99 per quart. I ended up buying like 13 quarts of it. (I don't know how true it is, but I read on here that you can run this oil for a long OCI, and at the end, drain off a little [depending on whether or not your car uses up significant amounts of oil] and add a fresh quart and go for another 5k or so, easy).
