I've seen quite a few guys on here like to run 2-stroke oil mixed with their fuel when they fill up. I went to walmart today to get some, thought I might give it a shot. My question is, which kind are you all using? I didn't even give it a thought before, but theres the type you normally mix with gas and then theres the type for stuff like snowmobiles that use oil injection. I went ahead and bought the stuff you mix with gas figuring thats probably it, but I just wanted to double check.

 

i am useing evinrude synthetic blend twc 3. some people will tell you not to use synthetic, but they cannot tell you why not.....i've been useing it for several years, and all is good

 

did I get the right type of stuff though? its the type you would normally mix with gas, for like say a lownmower or weedwacker. It also didn't say anything about it being low ash...is that ok? I know some guys said they just use the cheap stuff from walmart, so thats what I got, but I"m not sure if what I got is the stuff they were talking about.

 

I must be dunb too...What is the reason or benefit of using 2-strok oil in your fuel? Thanks Stroke

 

lubricates the fuel system, since the fuel doesn't do it anymore

 

The Inj Pump is of two varieties -

- one type, like the P7100 in-line, is lubricated by pressurized engine oil - the plungers merely pump the fuel to injection pressures

- second type, like the Bosch VP44 and the Stanadyne rotary's, use the fuel as lubricant while pumping to injection pressures

- ULSD lost most of the lubricity properties during the process of removing the sulphur

Adding 2-stoke motor oil, which is formulated for combustion-chamber service, is a good hedge against increased excessive wear on the IP mechanicals, particularly the rotary's, but also lubes the plungers\rotary valves, helixes, racks, etc, in the in-line series

Sulphur was removed from Diesel fuel, making it ashless - adding ashless 2-stroke should help with EPA\DOT Diesel vehicle inspections, starting in '08, some areas '07

Good ratio is 1/2oz per gallon of fuel

Syn or Dino - no answer for that, tho Diesel Fuel is Dino, with nothing on the horizon for Syn, so I stick with the Dino additive.

 

i think any 2 stroke oil is going to be good, it makes your engine run quieter, another reason is to lubricate the vp 44..... 2 stroke oil is made to burn so there shouldn't be any harmful deposits left in the engine, some say it improves mileage, but i haven't seen any improvement since i started to use it.... (150,000 miles ago)

 

Some lubricity component is added to ULSD, but, allegedly, it is done at the storage\shipping terminals - no guarantee that your load wasn't shorted due to equipment malfunction, or additive tank went dry half way thru the load, or myriad of reasons, any of which is detrimental to your IP - fillup your own tank, pour-in your own additive - only you to blame, if you short the load.

As my truck is fully warranted by the builder - me - it therefore behooves me to take the extra steps to ensure the added service.

 

There are really only two types... TCW and TCW-3. First is for Air Cooled 2-Cycle Engines.... second for water cooled! Snowmobile 2-Cycle, which has a thining additive to keep it flowing in cold temps... is usually TCW-3. Will work but not needed.
I would recommend you read the label and only use TCW-3. It's designed to burn cleanly at a lower cylinder head temp... due to it's water cooled application!

I did some testing and believe around one oz to 2 gallons is enough to get good lubricity. That's roughly 1:250.
Can't call my testing scientific but that quantity is the least I could use and still notice a smoother idle in my 24v!

I have been putting Amsoil Dominator 2-stroke oil through my truck lately. It is better for high revving, WOT racing, etc on my quad...but I have enough of it and so I run it through my truck as well. Quite a bit quieter and idle is a little smoother I think...but it might just be me.

 

I think they say not to use it because synthetic oils generally have a higher flash point, so it doesn't want to burn as easily in the combustion chamber.

That just sounds like a waste of money...

 

more lubricity with 2-stroke oil than with diesel additives? or is it a cost thing?

 

They are being logical...but wrong when it comes to 2-Cycle!

More BTU's and possible mileage because of the BTU's... but not better lubricity over a quality additive, IMO.

Lots more BTU in a quart of motor oil than in a quart of #2 Diesel fuel.........
