mixing petrol with Diesel

[whiteknight]

With all the hype at present over LPG systems for Diesels I remembered reading about some of you talking about mixing a small amount of Petrol with Diesel to get better economy and more bang.

Anyone done this and can comment on the results? what ratio of Petrol to Diesel do you use?

[RN]

Not sure about mileage but an old trucky told me that mixing a small amount of petrol with the diesel was good for clearing out the injectors. Why?? Well he explained it was something to do with the different viscosity of the two fuels that the petrol had cleaning qaualities and removed the gunk from the injectors.

Then again it could have been just one of those urban myths. I did try a bit of diesel in with the petrol in my Volvo Wagon years ago and it caused no apparent harm, but nor did it make any noticeable difference ( only in my mind...like a Hyclone_

[G.F.R.D]

From my understanding mixing diesel into the petrol would make no difference. But doing it the other way would. the petrol has a bigger bang so it adds and aids to the combustion of the diesel. Because the petrol is a more aggressive fuel it acts as a cleaner for the injectors. It is kind a like adding a bottle of an additive, I would assume. I only believe this in theory as far as a practicle application goes, I wouldn't mind knowing myself for reference sake.

[whiteknight]

Yeah the point I am trying to make is - is it worth adding 3 or 4 litres of Unleaded Fuel to a 50 litres of Diesel when you fill up?

[ronoor]

to be on the safe side just get a bottle of injector cleaner cheers ron

[dirtyGQ]

on the way to lcmp i put in unleaded so i drained most out but there was still aprox 12 litres in there and couldn't get it out so i fillled it with 80 litres of diesel.
It made a big difference and was told later that truckies do it regulary.
BUT ,mine is a td42 and newer electronic motors may have dramas with it. I now put 5 ltrs to every 50 and does make it more economic and perform better.

[whiteknight]

Took the plunge and put 5l of ULP in with 50l of Diesel today - definately makes a difference in power will keep an eye on the economy and see how it goes..

[dirtyGQ]

i'll tell you a secret a few of us are using and makes big difference to power and economy and works in all fuel types. 80mls acetone per 50 litres of fuel we have been using for 3 + months .

Isnt acetone nail polish remover? Not that I would know

Where do you get it from and how much is it?

one of it uses is to remove nail polish yes ...i get it in 4 litre tins $18 BUT take no responsibility for this suggestion nonetheless was told by an engineer in the airforce about it and me and about 6 others i know have been using it for at least 3 months and 1 is a mechanic and no problems . As explained to me is just really high octane ...... all care and no responsibility but am still using it and no probs

Post again in 3 months please ... if you havent rebuilt your engine, i might try it. Probly try ULP 1st though.
How much of an improvement in milege are you getting? Drastic/marginal?

well the fuel companies use toluene a industrial grade thinner and many other thing as well as detergent etc so i am sure that i will not be rebuilding my motor prematurely from using acetone using ulp i get approx 5 % and up to 15 % USING ACETONE .Why wouold you think i would be rebuilding because of acetone ?

Sorry, what I said wasn't based on any mechanical knowledge, just thought that It might have some 'side' affects on the engine .
15% is a pretty good saving, better than most of the 'fuel saver' devices around.

yer i personally think its no good reporting back what damage it has done in 6 months u probally wont see any unless its doing serious damage

its like comparing a engine that uses the best grade fuel you can get and then one thats used the cheapest nastiest shit around

chances are you wont see any diffrence till you get a fair few km's up on it
i would wait till some one has put say 80,000km's on an engine using this

wouldnt it be like putting a turbo or blower on running low boost as the petrol would give more compression when burnt

you know, with the way fuel prices are going, it may well work out cheaper to add all sorts of crap to your fuel, get killer mileage for ~2years, and then rebuild/replace the engine if it stuffs it up

[dirtyGQ]

don't worry there is already heaps of shit added to fuel especially diesel but none that gives you more economy or performance. We had a car motor blow on us 4 years ago and that was because of additives that are in most fuels as we had it tested .bp also had major problem not to long ago and had to compensate many people.

Use of toluene was banned in servos a while ago, caused serious damage to engines (burnt valves, cat converter). The servos did it because it was a cheap way of "stretching" the petrol and ppl didnt notice a tank of anything up to 25% straight toluene occasionally, but those that go their fuel from the one place every week ended up in the sh*t. Toluene is a benzene derivative, IIRC acetone isn't, but may have similar effects to the engine.

[bogged]

Mothballs were another old school trick.


I was told by diesel place that petrol will fuck the seals in the fuel pump on a diesel.

Napthalene or "Naptha", another of the benzene family.

Very interesting reading

I will probably be trying this next tank..

[dirtyGQ]

Ok spoke to the guy today about acetone and he runs everything with acetone in it. His 96 td42 has been going good for 3 years runnin with acetone in the mix. his first concern were injector pump seals but no they have held up great my uncle who does insterstate trucking has been using ulp for years and swears by it.... but hey if people don't want to try things up to them.

yes doctoring fuel is banned but apparently still common practice by servos as is collusion.(my opinion) for legal sake

AND reduce lubrication of the lift pump, and Rotary cam in later pumps.

Thatll cost you $$$$

Hmm acetone sounds like the go because u can just carry a little container of it and chuck it in just befor u fill up, easyer than pouring in 7L of petrol, cheaper to.

Where do u buy this stuff from??

[fnqcairns]

To cover the lubrication problem just add 100:1 2 stroke (or any oil motor oil) to cover the ULP.
To anyone with a more athletic mind than me (everyone ) would the dilution of the 100ml of oil added to all that diesel still cover the lack of lube in the ULP?

cheers fnq

So, by the time we add acetone, ULP, Oil, air, fart into the wind while wearing a tuu tuu, what do you save?

i agree its like biodesiel sure it easy enough to get some old fish and chip oil

but the steps needed to make it usable and safe is very time consuming and can cause damage if not done right

and then the law side of things apparently you cant make any or a certian amount of the stuff

ill just stick to standard ulp with some valve saver in it

only cost me about $50 a week in a fuel im happy with that atm



instead of spending money to save money maybe we should spend the little extra towards doing some thing to make the government see what needs to be done (might be more trouble than its worth)

just my 2c
feel free to agree or disagree

It is successful in very tiny amounts from about one part per 2000 to one part per 333. Mileage seems to taper off while HC emissions actually are greatly reduced with too much acetone. Acetone not only improves mileage but cuts pollution dramatically and gives longer life to engines. The peak gain in mileage comes between .20 of one-percent and .35 of one-percent acetone, depending on the actual vehicle which may be running gasoline or diesel fuel.

From here: http://www.lubedev.com/smartgas/additive.htm

All the links sound convincing, I may give it a try in small amounts. Will probly talk to a experienced diesel mech first if I can. And i dont think it's quite as complicaed as you make out bogged , adding 60ml/40L of diesel. I do the same at the moment with some diesel addidive and only notice about 40ks more to a tank.

[LuxyBoy]

I have been using the CEM (Cost Effect Maintenance) fuel additive with absolutely no positive or negative effects; damn placebo
First and last bottle of this i buy

On the other hand their oil treatment is fantastic; the engine actually feels freed when it is in. I know it sounds stupid but Whitenight tryed it cause he didn't believe me either; he now believes. Unfortunately it is a flush so it is only in for an hour Wonder what would happen if i left it in

Are you guys saying to use ULP and Acetone together just one of them

[fnqcairns]

Wonder what would happen if i left it in

Luxboy it may start eating your journal bearing surfaces and start wearing valves and contaminating the oil with ash.

Not worth it
