Outer Limits 4x4 Board

just checking to see if its still all good cos iam thinking about it and just wanted to see what ratio you guys are using

I am using a 10% mix for three tanks and then a straight diesel tank, just to make sure i don't get an overload of PULP (Premium Unleaded Petrol)
This in a N/A 2.8l deisel Hilux (3L motor)

what are the biggest benefits that you can see

i used to do up to 15% but then decided it was more hassle than it was worth.

More power, better fuel economy and i think there might be less smoke but i don't drive behind it much.

i know another guy running it through an turbo on the same type of Lux and has the same to say about it; tho he uses ULP not PULP

let me get this right......... you have a diesel and your mixing premium unleaded with it??????? fill me in please. long term effects, benifits, sorry i have a thousand thoughts going through my mind. first ive ever heard of this.



i know of some one who filled a diesel 100 series hire 4wd with unleaded and blew it up.

Petrol burns faster and hotter than diesel. With a minimal ratio (ie; 10%) what happens is the petrol ignites and starts the burning process creating a little more heat ensuring all the diesel burns. Gives it a bigger bang basically. This means each fire is more efficient theoretically giving better performance, better performance from same fuel delivery means better economy.
If you're friend filled the Hunjy with diesel then it would have been running nearly pure petrol and therefore it would have detonated every fire and hence rooted the engine!
Also Petrol is a good diesel injector cleaner just as diesel is a good petrol injector cleaner
Hope this helps.

there was a thread a few weeks ago about this, basically insted of using diesel cleaner a small amount of petrol is used instead.

This is a thread from a few weeks ago. It also suggests pure Acetone as a better (?) additive.

thanks for all your responses iam going to give it ago this weekend

I tryed the acetone and it did jack compared to the PULP

i going for the caltex most of the dirt bike guys use it the main feedback its better then optimax i have never run my tank empty so i gess it no more then 1 troopy tank but more then 75l

A heap of dirtbikes run Vortex at my work... Most petrol heads steer clear of optimax... its very inconsistent.

I think the go is Vortex or BP Ultimate

let me know how you go please might be just what the surf needs!!!

Anywhere that does fibreglass will have heaps of acetone as it is the thinner of the resin i think....

is it better to run more higher octane fuels? would this just be to avoid detonation? what are the cons of doing this? just if you put too much petrol in you could detonation yeh? any other problems like wear on valves or anything like that?
Cheers, Calvin

i heard truckies used to put petrol in their rigs to give em more poke and better economy, but ive also heard it can chew seals out in your injector pump if your not careful.

I would not go more than 10% from what i have read anything past 20% can be bad

I know a turbo surf owner that runs it and loves it, now puts it in his tip truck and it is great he reckons

Yes if your seals are bad it can make them worst but if your pump has been rebuilt and has the new type of seals it will be fine (so i have been told). I personally can't see this being a problem at 10%

iam quite sure that my tank is 90l i have done some searches and it makes sense for it is 1 off the troopy tanks.

I wonder if I would be pushing my luck trying this PULP trick on my 400k yota 2H engine.

What yas rekon? Anyone tried this on the older diesel's?

I put a ratio of 10:1 in my 75 series and it's going great even with 350000ks on it.

It did blow a fair bit of S*** out of the exust but now it blow less .

be aware that later rotary pumps use the fuel to lubricate pump internals, cams, pump etc.
Any percentage of petrol will reduce lube by that percentage.

So that means i should not run it all the time?

Maybe i'll only do it when i'm going 4WD .

nyet .... styrene is whats in resin as a monomer (carrier)

acetone is a solvent - cleaner.

so this is the same theory as lpg fumigation for diesels........ without the price tag

Yeah thats about it - in theory does the same thing LPG Fumigation does, helps burn all the diesel.

I have been doing it for 5 months or so now and there is definately a difference in power and torque. I run a straight diesel tank every 4 tanks or so and when i do I notice the difference :(

I'm not a chemist, so apologies if this is a dumb questions to some....

Does the diesel and petrol completely mix? Or can the additives during production cause them to seperate if left standing?

I'd hate to think that I was using a 10% mix, but due to seperation as the tank gets low, it's more like 20%....

well my 1st tank is empty and I didn't see or feel any diff. I might give it 1 more this time i'll put in 12-13l see if that does the job

I'm just about to finish my 1st tank with it, 4.5L in a 45L tank. MINIMAL, and I really mean minimal difference in power of hills, but it could just be placeabo its not hugely noticable. But fuel consumption looks like i might be able to squeez and extra 20-30ks outta tank, not sure I'll see soon though, Upto 380k's and have about 1/6 of a tank left usually get between 410-440ks.

i dont think i'll bother if its that marginal
