Found this on the web

2 cycle oil in the gas

I figured what the heck, and bought a gallon at Walmart for 12 bucks. To break even on fuel economy you only need to gain one extra mile for 5 gallons of gas treated.

I add two-cycle oil or Marvel oil for lube purposes of the fuel pump.

Our gasoline is a compromise. It is designed to meet emissions standards, give satisfactory lubrication to the fuel system and satisfactory gas mileage at an acceptable price. It is by no means perfect.

Many additives have been used to improve our fuels and 2-cycle oil has been one of them. I use several additives in my fuel for various reasons including Bell Lab's Ethanol Defense which, initially seems to be very promising but it's too soon to say anything definitive. Bell claims that Ethanol Defense offers several of the benefits of 2-cycle oil mentioned in the article provided by CHEAPMONKEE.

Unfortunately, our emissions systems are keyed to the performance of standard gas and if the system detects a lean exhaust, it compensates by using a richer gas mixture. This is a shame because in effect, the emissions system partially defeats the effect of more effective fuels.

Not having a science background, I really have doubts about my ability to interpret how emissions systems actually work when I read anything approaching a technical paper but it seems that our current systems only evaluate exhaust and blindly richen the fuel mixture when the exhaust is leaner than expected. Maybe someone with more expertise can offer additional comment.

A long time ago I ran a small percentage of I think Castrol? possible 927 can't be sure now about that number. I do remember it was a top end/2-cycle engine additive and I added it to my fuel cycle for the purpose of cleanplugs and top-end protection where the very hot temps hit moving parts in a 4 cycle engine. Never any problems.

The advice given by a two-cycle comp rider/repairman, the exhaust odor was great almost as quaint as a cherry tobacco smell.... Four-cycle normally don't require a gas additive, but my choice.

My HC emissions was 15 parts per million. And the CO was 0.0000 percent. Quite the POSITIVE issue. Two years ago my HC reading was 142 parts per million and the CO was .82 percent. BTW the proper mixture spans about 400:1 - 700:1...Too heavy and poorer mileage is likely.

If anything, it will probably cause emissions issues in newer vehicles.

Yeah it will hurt the converter if you dig some TC-W1 rated oil out from the 1980s at some ones garage sale.
TC-W3 is low to no ash.

doesn't Marvel Mystery Oil or Lucas top cylinder additive provide the same extra lubrication (and possibly bit higher compression) as 2-stroke marine oil? I've been using both of these for years.

I thought TC-W3 might eventually harm converters?

I tested this in our 4.6L 2000 Lincoln town car. I added enough 2 stroke oil to treat 20 gallons to 100 to 1 mix. I filled up the Lincoln ran it down to 0 miles on the fuel mileage indicator and filled it up with regular gas.
I did this for 4 tanks (4 tanks with oil versus 5 tanks with out) and closely watched the fuel economy. After the 4th and last tank of 2-stroke I could not see a difference in fuel mileage. I had tracked fuel mileage well before and after this test too.

I have 1 gas can I use for both the chain saw and pressure washer.
The saw is obviously a 2-stroke and needs oil in its gas, the pressure washer is a 4-stroke and does not need oil in its gas.
I use the saw gas to top off the pressure washer, if the pressure washer had its own gas can then the saw gas would sit around for 2 years before getting used and go stale.
After running several gallons of saw gas through the pressure washer over the last 2 years it wouldn't start the other day. Pulled the spark plug and it looked brand new. Turns out rain water got in the gas tank.

Looks like 50:1 mix does not hurt a regular gas engine's spark plugs.

I think it would be stretching it to expected to gain 1 mpg within that 5 gallons. I guess it's possible, but I'm skeptical.

I recently took my vehicle through DEQ and the emissions were dramatically lower than last test two years ago. So low that there is little doubt that the TC-W3 add helps. Significantly.

There is a 12% hill I coast down in '2' on my Automatic transmission. Before the TC-W3 treatment I would reach 40 mph by the time I hit the stop sign if I did not apply the brake. Now, with the TC-W3 dosing the car reaches about 32 mph without applying the brake pedal coasting down. So, the compression is increased by the TC-W3 treatment as mentioned in the LS1 thread and on other sites such as BITOG. Higher compression can only be better and should increase efficiency a little bit. Cheap, effective, and easy.

long term results

"Sarge" OP from LS1.com "Just an update...we had the heads off putting the new valves/cam etc. in the Silverado. Pistons were shiny like new. 75K with the TCW3. Plugs were pristine.

The jury is still out on that question. May take several years of dedicated testing to find your answer ...

I put some TC-W3 in my brother's Grand Caravan and he reset his computer when he filled up and took it for a trip and the computer reported about 28 mpg. For some reason these minivans really benefit from the gas treatment more than average. Read down a few pages in the LS1 thread.

Long term I dont see why it would cause any ill effects as long as you dont use too much of it.

I am not sold on this. I will agree that gas in not as good of quality of the past, but adding your own "snake oil" to it is probably not the best answer. What are the long term affects to it. I did not see naything addressed on that.

I used to use Marvelous Mystery Oil in my tank. It would boost mpg but I don't know if it was enough to save money.

Last time I looked, most of the cars on the road today are "liquid-cooled"

Might as well give it a try.
My best friend who is a mechanical engineer tracks his fuel economy with high precision had his top 5 or 6 highest MPGs of all time with gas tank fill ups that included lucas fuel addtive which contains an "upper cylinder lube" a lot like 2 stroke oil.

The best 2 stroke oil on the market right now by far is shindowa red armor, but its a little pricey.

Marine 2 stroke oil is designed for engines with liquid cooling systems.

That's my problem -- there was no "SuperTech" at my store! Price I quoted was for the cheapest TC-W3 they had...

Sarge says in their testing that there was no difference in performance in various brands. The Pennzoil is 20 bucks. The Super Tech was $12.15 at my local Wally World.

Guess I need to shop at this guy's WallyWorld. Best price I can find for the product in question is $19.73. Might be a good idea, but I'm still a bit skeptical ...

It looks like an interesting premise, and from the way that one fellah carries on, he seems totally convinced. Guess I need to swing by WallyWorld, and make a purchase ...
