-   -   My Experience Of Adding 2T Oil In Fuel (https://www.team-bhp.com/forum/technical-stuff/16128-my-experience-adding-2t-oil-fuel.html)

Hi all,

Recently after studying effect of PIB(PolyIsoButylene....also known as synthetic rubber or Butyle rubber) ....I decided to try it in my car.......

Amount to be added is 0.8 ml per liter of petrol & diesel.....preparing the mixture with small amount of petrol then shake well & add directly in tank like Acetone....immidiete difference is very good pick up & power.....very very less exhaust gases.....even not visible when we raise throttle.....& smoothness in engine performance..........

I added castrol Power 1 super TT 2 stroke engine oil which is green in colour & easily available everywhere......added in the ratio of 0.8 ml per liter of petrol.......

There are lot of information available about PIB as fuel additive......

http://patft.uspto.gov/netacgi/nph-P...&RS=PN/5906665

this link demonstrate the benefit of using high moleculer weight PIB in fuel.....castrol 2T oil contain at least 25% PIB....hence I went for it.......

http://www.sciencenews.org/articles/20000902/fob3.asp

This is the article showing benefit of PIB in todays car......it states that the amount of money spent on chemistry of fuel is very less compared to the technological advancement in automobiles.......this wonderful PIB changes the physical property of fuel..........it increases the volumetric efficiency in combustion chamber......when fuel enters combustion chamber through injectors which makes them into very very fine droplets....droplet size below 50 micron tend to vapourise during induction.....PIB suppresses the below 50 micron droplet formation....hence there is more homogeneous mixture when it enters combustion chamber.....this result in total burning of fuel...also small droplets do not stick to cylinder walls.....also this improves the lubricity of fuel.....fuel particles are rigid to travel along the fuel lines...when we press accelerater...there is time leg of fuel which travells from tank to injector & which takes sometime compared to instant response we need......adding PIB in small amount improves this aspect of fuel......it travells fast giving good throttle response....

It can be added with acetone too....both working differently on fuel & combuston......

My main observation instantly after adding this....

1)Excellent power response...much more then I felt with Acetone...

2)Very less blue white smoke from tail pipe.....I checked it many time by raising the accelerater....

3)Engine runs very smooth......

finetuning, another exciting experiment from you ..

just begun to read the links. but one question for you in the mean-time. are there any negative effects for diesels mentioned any where?

Dear condor,

I think this additive works with changing physical behaviour of fuels..petrol & diesel...although in my most of reading I didnt find any..........The invention of using PIB started with limiting aircraft explosion when any bullet hits its fuel tank......they found that with PIB added in right small amount reduces the explosion magnitude & size......encouraged by this they found it related to automotive fuel too......

this is the link...http://www.gtatech.com/test_gas4.html

Enjoy.....

thanks, FT. questions, questions:

* how did you get the figure as 0.8ml per liter?
* have you tried on petrol or diesel?
* have you noticed any improvement in FE?

Come to think of it - there is an old trick that was used extensively, in the days when the price of kerosene was sufficiently low, compared to diesel. When short of diesel, the practice was to mix kerosene and 2T oil to get a concoction useable in diesel engines. This is from the times when we didnt have the number of petrol pumps we have today, and the cost of the kerosene + 2T oil was still comparable to diesel.

So, we should be able to use this method without any problems ..

Dear condor,

When I went though acetone implementation I found use of Torco GP 7 2T oil used in the ratio of 1 oz per gallon to be added with acetone ...means 0.8 ml per liter in petrol & diesel cars.....now here we have same 2T oil i. e. castrol super TT.......I tried in my petrol car...Improvement in FE will take time.....most visible benefits are instant pick up...good power...very smooth engine....it can be safely added in diesel engine....

Dear FT,

You have tried both with Castrol super TT and Acetone, pls tell which one is better for Petrol MPFI enjine car (mine is Palio 1.2 aports). Also pls share why you think which one is better method among the two.

Regards.

Dear jdutt,

Both acetone & castrol TT works diffferently....acetone helps fuel molecules vapourise better to give better combustion......fuel doesnt burn until it changes its phase from liquid to vapuor....it reduces the surface tension of fuels.....its bcz of high surface tension many fuel droplets do not take part in active combustion.....this is waste of fuel.....this is mimimised with tiny addition of acetone......

Also when fuel in injected or carbureted....it sprays like a cone.....which consist of many different sizes of fuel droplets......sizes below 50 micron tend to vapourise so fast during induction phase & bcz they vaporise fast they ignite fast giving spikes of high temparature inside combustion chamber......this gives knock...pinging....a kind of irregular combustion...bigger droplets burn later on....there is very minute millisecond difference between this.....but in all such case combustion is not uniform as fuel air mixture is not very much uniform......what PIB does is it delays the burning of small droplets below 50 micron sizes....so till compression stroke....nothing gets ignited...and when spark ignites fuel...all of the mixture ignite giving total combustion.....this also reduces the temparature spikes which were responsible for high engine temparatures......this result in power gaini....crisp throttle response..... it is proved that adding tiny amount of PIB solutions reduces the temparature of engine &reduces exhaust also.....in total clean burn condition there is no pollution...

Try using one at a time.....in required amount......2.5 ml per liter is acetone & 0.8ml or 1 ml per liter is castrol TT............its very good for diesel fuels....recently I used in tata indica diesel car...it improved aceleration...power & reduced black smoke......

This seems to be quite intersting. I recall my car doctor telling me to add 200 ml of mobil (is 2T any different from standard mobil oil?) after topping my tank up with diesel (he told me do this to only diesel engines). He said that the difference would be remarkable. Of course, I never tried coz I thought that adding mobil would result in gumming of the nozzles.

Now that you say that adding 0.8 ml per litre of diesel is better than acetone, it has put me in a dilemma. I have been using acetone inmy Safari-1998 ever since I joined this forum and my views are posted here on its results.

Also wondering if one ends up adding 2T oil in the fuel mixture, wont the spark plugs get black with oil being burnt in the combustion chamber?

But i guess if the quantity is only 0.8 ML it shouldnt make a difference.

Yes Acetone Rocks so am gonna try this also.

Will post the results when i am done.

FT, thanks! Initial observation - the Indigo Marina engine is running a little smoother, quieter, and there's an improvement in power/response. More details when I have some figures in hand.

gd1418, 200ml per tank-ful could be on the higher side ..

Dear gd1418,

I think using any 2T oil will have benefits of PIB.....it also reduces smoke generation....2T oil is different from standard oil.......most of 2T oil contains at least 15 to 35% PIB...

http://householdproducts.nlm.nih.gov...ne&prodcat=all


It can be used with acetone too.....so not to worry with 0.8 ml addition.......u will get increased power....still reduced emission & smoothness of engine....also remakable thing is reduction in engine temparature......if u try this keep observing engine temparature.....u have to prepare mixture before tank refill with little diesel....so that when refilling...

Enjoy.......

Dear kaizer Sozay,

Tiny addition of 0.8 ml mixes well with petrol.....this delays the early combustion of sub 50 micron fuel droplets which gives spikes of high temparature.....so we get controlled & uniform combustion.....this also improves the lubrication of fuel lines......I think if addition of this is in high proportion then there maight be burning problem......

Enjoy.......

Main benefit of using 2T is it increases the volumetric efficiency of engine......

Imagine during induction phase of 4 stroke engine....fuel is being carbureted or sprayed by injectors into fine mist...its like a cone.....no fuel molecules will be equal in sizes....now suppose there are 100 molecules being sucked inside cylinder....of this 30 are very very fine well below 50 micron sizes...so they evaporate fast...& when ignition starts when piston reaches near TDC(Top Dead Center)....these 30 molecules burns first giving instant power....increase in cylinder pemp. & pressure......large remaining molecules evaporates less & they ignite later on......many of them also dont get phase change & are responsible in the loss of power......

PIB delays the vapourisation of those 30 molecules till all 100 molecules are ignited togather....this happens because of extensional viscocity this imparts to the fuel particles........this is the change in physical property of fuels....hence change in combustion.......those 30% were now burning with remaining 70% giving fullest possible power......so in nutshell we are gaining the volumetric efficiency....volume of air fuel mixture is high inside combustion chamber at the time of ignition so we feel increase in power......in todays ever rising cost of fuel every drop saved pays......also intermitant temparature spike charecteristc of combustion is reduced....so engine runs cooler....compared to earlier....I hope I explained in better way....

Enjoy..........

Finetuning, I just prepared a mixture of 400 ml petrol & 8 ml of Castrol 2T oil. The 2T oil completely dissolved in the petrol, tommorow morning am going to pour this into my petrol which has around 10 Litres of petrol,

Will be drving around for approx 70 kms should be able to post the results by night. Hope to have the same results as Condor

Am taking this risk as I will be opening my Engine head on wednesday to get the Grooves done.:Cheering:

I have driven 90 kms today, the petrol was Power .
Added 2ML Acetone & 0.8ML of castrol2T oil per litre
The results WOW! throttle response really really smooth. very little engine vibrations. FE cant comment as of now
When you hit the gas the power curve is very smooth.
Another Great Find by Finetunig.
