Open discussion on using TC-W3 oil as an additive

If you are concerned, stop using it a tank or two before the smog check.

No smog where I live. But running TC3W is very popular on the diesel forums, some guys must be running it in those areas.

Here is the diesel additive lubricity test I referred to earlier:

Thanks for that, that is very interesting.

TCW3 oil is one of the better performers (not in the top tier though) and certainly a very good value. I do wonder how it does in lower doses though and how well this translates as a gasoline additive. Their testing has it at 1oz per 1.5 gallons rather than the 1oz per 5 gallons that is typically recommended for gasoline engines.

Also intriguing is that MMO came up as no statistical difference in lubricity. Now, there may be other reasons for using it, but lubricity was my primary concern, so I'll stick with the TCW3.

For the purpose of this test, the ratios were intended for diesel - even still - I am assuming there is some positive correlation between the results of this test (the addition of TC-W3 lubricty being a net improvement in lubricity) and a similar test if it had been run with gasoline (and the reduced TC-W3 to gasoline ratio). It seems, if nothing else, that TC-W3 does not appear to reduce gasoline libricity.

But I do not have definative information to back that assumption up.

The study does include some other products (with a higher improvement in lubricity) that appear to be suitable for either diesel or gasoline.

are ya'll using synthetic or reg??

I could not locate the synthetic pennzoil. At this dillution level, LS1 forum thinks it does not matter for what we need it for?

just look on the internet, the synth was $30+.......regular was $5.

makes sense w/ the deluting

Same here.

For less than $10/gallon, it's pretty cheap too.

I'm not sure how the results of using 2 stroke oil in gasoline engines is going to be quantified. Use in diesel fuel is well tested, and TC-W3 is so-so as a lubricity additive, but what on earth would the benefit be in gasoline engines? It will likely reduce octane, and at the low levels being tested, the very low lubricity of gasoline is likely not affected (not that extra lubricity is necessary).

Post results. I am curious to read more than anecdotes about smoother idling, you know to save fuel you should not be idling much anyway, right?
