Hi all, I've been around for a while but recently got a 2008 ibiza fr tdi with the BLT engine, as such I find myself here.

I'm not looking to reignite the debate on whether this is a good idea or not as I have done some reading. I'm going to try it having read how modern diesel fuel is going lower on sulphur and higher on bio-mix, and after my car not feeling quite as spritely after a top up at Morrisons, I'm looking to raise cetane level and help keep fueling parts lubricated. The car runs very clean so smoke is not an issue, I consider this a proactive measure, rather than one looking to fix a problem.

I read a post by someone on here who had used and recommends castrol actevo 2 (mineral), and I have ordered a 1 litre bottle (looking to put 200 ml in with each fill). However I have a bottle of semi - synthetic, low smoke/ash 2 stroke in the shed that exceeds the standard requirements (sorry can't remember the classification). I did read that the pd130 may be more sensitive to some additives than others, but will this be ok?

Cheers all

Jon

Super market diesel is your issue!

Can Deffo feel it if I use it in mine,for the sake of a few pennies per litre stick to the big branded garages imo

Otherwise you can buy Cetane booster off E-Bay rather than using chain saw oil!

Can't you just add some redex diesel treatment every other time you fill up?

I agree. I've met (and seen his records) a guy who gets ~1/6 worse fuel economy off Tesco diesel than off brand name.

Yeah I'm pretty sure that Mozzas stuff was ball bags. I had half a tank of shell (my preferred choice) and then brimmed up with that stuff thinking with diesel it matters less, but it appears I was wrong. As I've still got a full tank to go (economy is very good) I've put some millers economic boost in. I'm also thinking about lubricating the fuel system and increasing mpg and have read good reports on 2 stroke being largely effective. Wondering if this more standard semi - synthetic will be ok?

I agree, I once used supermarket diesel and found the lack of performance, I stick with Shell.

 

DB.

Two-stroke oil does not contain a cetane booster, it is a lubricant only designed to condense out of fuel droplets and coat the bearings in a two-stroke engine crankcase in a very thin film with an extremely high shear strength, it is not suitable for any other purpose since there is nothing for it to lubricate in a modern diesel, the valve stems and bores are already lubricated with engine oil because it's a four-stroke, not a two-stroke. It used to be considered useful in old-tech diesels with mechanical metering pumps.

Does it not help the burn, hence the increase in mpg? I have read people claim benefits in more modern diesel engines, including the pd130. Does it not assist in lubricating the fuel pump?

Nope, what 'people' not engineers then?

Partly, yes, as well as people talking from personal experience, including people on this forum.

I take it you've not tried it then as you don't think there's any need to? I do hear what you're saying, but I've also read some interesting stuff in favour.

I doubt it'll do any harm, I'd be interested to hear what lay-snake-oil salesmen claim it actually does.

Admittedly I'm no engineer, but I like the sound of the effects like less smoke, less noise, improved start up, smoother running, better throttle response low down, better mpg, which is in the majority of the accounts I read. Other than whatever additive I choose I will be sticking with shell, and put v power in when I get chance (v power diesel is rare over this way).

Hi,

This was debated to great length on " caravan talk " forum the results were quite interesting ( some with photo's ) so much so i bought a -er- case of the oil ! i have been useing it since and while it does not seem to increase mileage it has made the engine quieter ! When getting it M.O.T  i asked the staff about the readout on the exhaust to be told -its very low mate . So is it any good and whats the history behind it ?  Well we were advised to use Actevo 2 minaral ONLY as any other stuff can **** up the cat. It is supposed to have been started by B.M.W.

Yes some stuff does make for interesting reading, I forgot to mention emissions. I think I will stick to the full mineral actevo, got a litre bottle coming for £8 so it's a lot cheaper than other additives. I also believe Benz did a 'round the world test' on their diesels and dosed each tank with a bit of 2 stroke to aid longevity of some the internals and injectors.

I can only re iterate what the Skoda handbook says on TDI engines. "putting any additives is not advised, as it CAN damage the engine".

They would say that though wouldn't they? Does v power not include additives? Use of 2 stroke is always debated but a lot more people readily use millers, red ex etc.

I dynod my car on asda diesel twice virtually no difference! I just occasionally buy one bottle of millers eco max a year and use that.

What was the asda diesel compared to? Mind you it's not power gains I'm after, more about smoother quieter running, running clean and good throttle response. The morrisons half tank didn't seem to agree with mine at all, I've just put some millers eco max in with that to blow it through. It's a funny one how different fuels can effect cars differently, I dare say most supermarket fuels come from the same local refinery, so it also depends where you are. Most if us in petrol terms in the mk1 Octy swore by v power, but a few reckoned there's ran better on momentum and didn't like v power much at all. I drove the car back from peterborough when I bought it, around a 4.5 hour drive on a half tank of v power diesel topped up from empty, and it ran sweet as a nut. Problem is choice is limited round here. I have shell but no v power on the diesel, or fuel save, it's standard which I believe used to be called shell extra.

Well ( touching a large lump of wood ) as far as i know no problems , it was posted on the other forum that it had been known for dealers to put some in the tanks of demonstrators..............

Personally I do drop a bit of 2 stroke in. I'm not after poweeeeeeeeeeeeer increases by doing it, I do it for preventative reasons, so the fuel pump gets a bit of lubrication. This is because I use supermarket fuel, not by choice, but because I use a Fuel Genie card.

What does that do, other than make your engine vanish in a puff of diesel smoke?

What 2 stroke do you use mate? How long have you done it for?

Only use mineral not synthetic or part synthetic. Mineral 2t oil burns better where the synthetic and part synthetic don't due to the make up.

Fuel is fuel. Supermarket petrol and diesel comes out the same tanks as shell esso BP and others. Depending which retailer it's off to depends what additives are added. That's all. Base fuel is the same no matter what including 95 Ron petrol and 99 Ron. It's purely additives that bump them up to that.

I use 2t oil in mine. Makes it nice and quiet sharper throttle and no smoke at all. Think its comma I'm using. Put 250ml in a 54ish l fill in my fabia. Didn't put any in this last 2 tanks because I forgot to fill me bottle to take to the filling station and the car sounds and feels naf.

VAG are the only engine builder that used PD technology. Pretty much everyone else went common rail out of the box and VAG was forced to move to that when they couldn't hit the emissions targets any other way. That's why the PD engines use a completely different oil standard to everything else. Be very careful using any information gathered on Peugeot (PSA) or Mercedes Diesel engines because they are different. Ford used a mixture of PSA and VAG sourced Diesel engines but ultimately I've got a PD130 with 254,000 miles on it and it gets nothing but supermarket diesel and regular oil changes with the correct oil.

Most people never see any benefit from 'better' fuel because they don't fully rev the engine so they very rarely make and hold peak power. Even then, the ECU has to learn that better fuel is available and change the settings accordingly. And that takes at least one complete tankful of fuel (500 miles). If you drive the car hard for 500 miles, it will learn that and adjust. And you get worse fuel economy as a result. Even if you suddenly go on an economy driving spree, it won't set itself to the full economy setup until you've done about 500 miles driving consistently economically. And then you'll wonder where the 'go' has gone.

As has been said earlier in the thread, many people want there to be some secret 'snake oil' that for some reason must be kept secret. There isn't.
