Diesel owners that add 2T oil to fuel

[tsupermario]

boss anong fuel station?

[MrQ5]

boss anong fuel station?

dito lang yun sa nueva ecija, independent fuel station named "speedway".

[9701]

added to bottles of shell 2T with decarbonizer on a full tank of diesel on my 03FM. Question lang po mga sir: is there a need to change my fuel filter? TIA and good am.

[ongie28]

*9701, much better to replace your fuel filter bro....Baka luma na rin siya at kailangan mapalitan for better performance of your 03FM......

[9701]

thanks for the reply sir ongie28.

[dvldoc]

Yes you can.

[nebblue]

Yes you can.

Thanks sir dvldoc, just making sure i won't be messing with the engine sensors, since some posts here pointed out that models 2007 and up are not confirmed as to compatibility with 2T on diesel fuel. By the way, i'm using Shell Fuelsave diesel. Is this variant different from any other Shell diesels? Sorry for asking to much questions. I'm really a newbie in diesel. Thanks so much for bearing with me.

[dvldoc]

That applies to US brand diesels, There are only a few common rails in the Philippines market that make that higher nozzle pressure, and the 2.5 D4D and 3.0 D4D is not one of them.

this is the ptt 2t fc I bought in subic:


PTT Philippines Corporation

[janalla]

Yup, that's PTT's 1-liter FC-rated 2T that I saw at national highway, PTT San Rafael, Bulacan. It costs P160 per container there. You can see the FC rating at the other side of the container.

[regaia]

OMG, someone must be hording PTT 2T, that's the same place where I went to buy 2T just a week ago haha

[Ry_Tower]

Pakshiyete, suwerte niyo naman ang mura. P131/ltr Shell 2T na FB rated lang eh. Sa P160 FC rated na sa inyo. Nice....

[dvldoc]

Back read a bit your see why you don't need to use FC, You don't need to use it because it does not matter your already sucking down oil mist through your crank case vent system so it's a moot point to use FC rated oil. If you can't find it go with next JASO rating down.

[MrQ5]

weh ang mahal din pala ng PTT JASO FC para castrol ang PRICE PhP35/200mL ang castrol...
*Doc if i use the BIOdiesel like SEAOil do i need to mix it with to 2T?
The lubrication based on chac ofNVH of engine of using Biodiesel without 2T is almost the same when im using Petron diesel with 2T, my only concern is the anti-wear and tear, can you chime in on this. TIA.

[dvldoc]

I use flying V biodiesel with the 2T, The biodiesel helps out a little with smoothness but nothing like the 2T, plus 2T helps you burn more diesel. My engine still had the bad shudder when your turned it off even on biodiesel but it's much reduced with the 2T added.

Just for the benefit of everyone who are interested, I compiled the list of FAQ’s for using 2T Oil:

Q: On what engines could I use it?
A: Diesel and Gasoline Engines. It has been used successfully on Sportage (1st gen), Innova, Trooper, Starex (late 90’s), Strada, Montero, Vanette (local), Crosswind, Tamaraw FX, Sportivo (05), Hi Lander, Carens, Eagle, L200, Alterra, Adventure. It has also been used on the following engines 4m40, 4jx1, 4dr5, QD32ETI, 4BE1, 4D56, CD17, 4JB1, 4m41, LD20, 2CT Turbo, KR2, 1KZ-TE, TD27, duratorq TDCi, OM615, R2, 4AJ1, 4D56t, 4JG2, 1HD-T.

Q: So I could use it on any engine?
A: For the Philippines it is pretty much good for any diesel, except BMW, or Mercedes and the newer rovers (high end stuff) with extremely high rail pressures and super advanced piezoelectric injectors example these cars are making 2000bar/29000psi of fuel pressure. FYI, this includes Hyundai R-EVGT equipped vehicles.

Q: What are its benefits?
A:
1. Cleaner Burn
2. Lubrication and reduction of wear in Fuel System, Injection Pump, Injectors, Cylinder
3. Eliminates shut off shudder
4. Better fuel economy
5. Reduces NVH
6. Reduction of RPM at idle
7. The used-to-be foul-smelling smoke/exhaust has been minimized.
8. Retention of Engine Oil TBN Longer

Q: Does it increase horsepower, like nitros?
A: No, pulling power and top speed would remain the same

Q: If its so good why doesn’t the oil companies use it?
A: Because of Emission Standards. The less-processed diesel fuels of the past were good boundary lubricants. This was not caused by the hydrocarbons that constitute the bulk of the fuel, but was attributed to trace amounts of oxygen- and nitrogen-containing compounds and certain classes of aromatic compounds.
Lubricity enhancing compounds are naturally present in diesel fuel derived from petroleum crude by distillation. They can be altered or changed by hydrotreating, the process used to reduce sulfur and aromatic contents. The use of fuels with poor lubricity can increase fuel pump and injector wear and, at the extreme, cause catastrophic failure.
Hydro-treatment removes the fuel's sulfur as well as other componets. The treatment removes nitrogen compounds, polar materials, bicyclic aromatic, polycyclic aromatics, and oxygen compounds. While the removal of the sulfur has shown no detrimental effects on the engine, the removal of the other coumpounds have lowered the lubricity of the fuel. As a result of the lower lubricity, the fuel is less tolerant of contamination by water and dirt. The lower fuel lubricity can be seen as abrasive wear of fuel components. Fuels that have a low lubricity may not provide adequate lubrication especially to plungers, to barrels and to injectors in your fuel system.
The sulphur level which is currently 500 ppm for Euro II in Philippines are just high enough now that the older diesels still run decent on them but not great. And why it only takes a little 2T to get them smoothed out. Shell V-Power Diesel and Petron Turbo Diesel, are Euro II for example.
CRDi (common rail direct injection) turbo diesel engines are in the market today can run Euro III- (less than 350 ppm sulfur) or even better, Euro IV-compliant in some of the higher end turbo diesel ie, BMW, and Benz. You will not see Euro III, in the Philippines anytime soon because the economic damage will be to great due to the amount of older diesels still in service and running on the road.

Q: What are the negative effects of using it?
A: You sometimes get a black deposit in the tailpipe of your exhaust when you begin using 2T Oil

Q: Black Deposit is bad right?
A: Not necessarily, the reason that you have more build up at your tail pipe when you first start using 2T Oil is it's cleaning your system. Think of it like putting engine flush in your vehicles oil except it's in your fuel system, it's going to knock lots of gunk loose and it's got to go somewhere. It will eventually clear up on it's own. And as we know the fuel quality in the Philippines is not the best so you will have a pretty good amount of build up to knock loose.

Q: How about my catalytic converter, would it be damaged by using 2T Oil?
A: 2T does not really have any effect on a diesel 2 stage Cat like a gas engines 3 stage cat. This is one reason you can use CI-4 oils and high zinc oils in diesels that can shorten the life of the converter of newer cars. But even then it's only knocking it's life down by about 25% on a 3 stage converter. So basically on a diesel it's no real measurable effect on converter. The practice of adding 2T has been around for over 10 years.

Q: Will using 2T oil make my Injector leak?
A: No, the orifice on a injector nozzle very tiny it will not really leak when not under pressure from the injector pump unless they are physically damaged or the orifice is worn out and you will get a big white puff of smoke on start up.

Q: How does it do it then?
A:
First, the 2T oil burns so this extra catalyst helps burn diesel fuel that would have gone unburnt.
Second, 2T oil has the same detergents as regular oil which is calcium, magnesium and boron so this helps break down carbon build up.
Third, 2T Oil also contains zinc and phosphorus which gives the lubrication to the injection pump to make it run at optimum level.
Fourth, 2T also contains sodium and potassium which is for anti corrosion, keeps carbon from sticking

Q: Okay, I’m convinced, what kind of 2T should I use?
A: JASO FA/FB/FC/FD rated. It does not matter what JASO rating you use. Do NOT use synthetic 2T Oil.

Q: I read/heard that I should use only JASO FC, is that true?
A: No, it's simply because you get recirculated oil back through your combustion chamber via the crankcase ventilation already and recirculated soot and carbon via the EGR. The tiny amount form a 200:1 ratio has no measurable harmful effects so you can use any rating you want.

Q: Then why do some people recommend JASO FC 2T?
A: JASO FC 2T does have a lower ash content so it helps more with deposits while still lubricating the engine.

Q: How about JASO FD, it should be better right?
A: You can also use JASO FD 2T, it's basically the same as JASO FC 2T but has more detergents i.e. calcium and magnesium which I rather have the smallest amount possible.

Q: How much should I place?
A: Ratio of use for Diesel engines: 50ml = 10 liters; for Gasoline Engines 15ml = 10 liters

Q: I was able to buy a special 2T Oil it has an additive called GT Oil, should I use it?
A: No, don't use 2T oil with other additives in it. Unless you can look up the MSDS before you use it, stick to basics. Keep it simple guys.

Q: I checked my engine oil after using 2T Oil, I noticed that the oil in my engine is now higher
A: Your oil level will be higher after letting the vehicle sit, it's called drain down time. You have oil in the heads and the rest of the engine that settles back down into the crank case. There is also a slight difference between hot and cold. Also remember the 2T is being burned during combustion and it's only 1:200 the of the fuel. It's not going to make your oil level rise nor will it dilute your oil. A non functioning anti drain back valve can cause this, The bad thing about this is your starting you engine dry when this is happening causing tons of engine wear. Start up noise will be a indicator of this.

Q: What other things do you suggest to get my rig run in tip top shape?
A: You should add a oil catch can.

Caveat: I just reproduced the answers in this topic, ALL of the information contained are provided by the respective posters (mostly doc) except the phrase "Emissions Standard" which I added

Sir Regaia,

Wala po yung YD25DDTi ng Nissan sa FAQ’s for using 2T Oil. Thanks po and very informative po yung summed up FAQ nyo.

[SELEGNA_35]

Good Job!!

[Ry_Tower]

I do believe 2t helps improve FC. I tried not using it and it feels like the car is sluggish and FC is not that good. I guess the engine is expecting a good fuel already. Even just an FB rated 2t.

Sir Ry_Tower,

Puede po ba malaman yung sasakyan na ginagamitan nyo ng 2t, kasi gusto ko lang po makasiguro na compatible ang 2t sa navara engine 2009 pataas. Nabasa ko po kasi sa ibang forum, patrol4x4.com po yata yun na hindi daw po puede 2t oil sa diesel kung merong DPF (diesel particulate filter) yung sasakyan. Medyo nalilito at naguguluhan lang po. TIA po.
