so i talked to a fellow DTR member today and filled my tank and added 2 8oz bottles of universal 2 stroke oil from wal mart. i did notice a change in engine rattle. but the question i have is wal mart sells a gallon jug of whats called outboard 2 cycle oil. can i use this or is the outboard different? i would just like it because its easier to buy in large quantaties.

 

I use the gallon jug outboard oil from wally world, there may be different additives but unless you go synthetic I would guess 2 stroke oil is all about the same.

 

Its not the same, you need to use the 2stroke oil with the TCW-3 rating. (It may be TC3-W I always get it mixed up). Either way, that means it is ASHLESS. If you run regular 2 stroke you can run the risk of gumming up your injector tips and ending up with sludgy build up in the combustion chamber.

so i basically need to run one that sauys tcw3 or whatever

 

Yep I run 1 oz of wally world tcw3 2 stroke oil to 1 gallon of fuel

Been workin good so far

 

What is the benifit from using 2stroke oil in the fuel.

 

it adds additional lubrication to the fuel that the ultra low sulfur diesel lacks now a days. by doing that it helps to quite the engine chatter down a little.

 

AAAHHH!!!! I didn't realize they chattered . I think I will try it once I get to drive my truck again.

 

ryan it does make quite a difference. i drove homr from my local walmart and notced a large inprovment in engine chatter

 

I know there is plenty of debate over the "correctness" of using WMO, but I find that adding some (the % is up to you, some run up to 75%) quiets the pump substantially as well, and supposedly adds the same needed lubrication.
(mine is much quieter)

OF course, YMMV, use at your own risk, blah blah blah.

 

The gallon jug from Wal-Mart is the TCW-3 stuff too. It's what I use in my Dodge. The Benz gets nothin', the pump on that engine is like a P-pump, it is lubed and cooled by engine oil. It's the rotary pumps like the VE and the VP44 that really need help with fuel lubricity, inlines will run on about anything and be happy.

 

One of the other diesel sites has an over-sixty-page discussion on the topic of mixing two-stroke oil in diesel, along with some well-researched listing of the preferred two-stroke oils in order of preference.

If I recollect properly, Pennzoil Universal TC-W3 was No.1 and WalMart UNIVERSAL, not OUTBOARD, TC-W3 was No.2.


Not all TC-W3 oils are ashless; some have more ash than others.

The WalMart OUTBOARD had quite a bit more ash content than the WalMart UNIVERSAL.

I have used the WalMart OUTBOARD with no noticable issues, but will buy the Pennzoil or WalMart UNIVERSAL when it is available.

 

Would you believe that stuff even works in my Suzuki two-stroke motorcycles?

 

So you guys that are running 2 cycle oil, do you quit with winter fuel?

Reason I'm asking is thus: If one uses a winter addative such as white bottle Power Service, does this cancel out the lubricating effects of the 2 cycle?

Is one better off just running 2 cycle all year? Or just the summer?

Basic question - is 2 cycle and winter addative compatable?

 

You can used it... but you don't need too. Urban legends on USDL not having adequate lubrication.

"(ASTM) adopted the lubricating specification defined in ASTM D975 for all diesel fuels,” Nowatzki says. “The ASTM D975 standards specify the minimum lubricating characteristics of No. 1 and No. 2 diesel fuel, but do not specifically address petroleum diesel blends with biodiesel. Also, No. 1 diesel, commonly available during winter in the northern parts of the U.S., generally has less lubricating ability than the higher viscosity No. 2 diesels.”

The ASTM D975 standards for lubricity set the maximum amount of wear on materials when tested with specific fuels or blends of fuels. The test apparatus is called a High Frequency Reciprocating Test Rig (HFRR). Both No. 1 and No. 2 diesel test results cannot exceed 460 microns of wear when tested in a HFRR. A lower wear score indicates better lubricity. Biodiesel has been tested at varying concentrations with No. 1 and No. 2 diesel fuels. The results indicate that a 1 percent blend of biodiesel with No. 2 diesels is sufficient to reduce the HFRR micron score below the required 460 micron standard. However, a 2 percent biodiesel blend is required in No. 1 diesel to get the HFRR micron score down to 460 microns."

Fuel manufactures were aware of the problem and have adjusted...
