Title: GTD and V-power ?
Post by: Steve30 on 29 December 2010, 20:59
I have been using V-power diesel since i bought the car in March 10 , Its now costing 1:33 liter in London at them prices im thnking of useing normal derv?

My question is there any point in carrying on useing this stuff? I do think the engine runs better also feels a bit quicker or am i imagining this?  :undecided:

It's hard to tell the difference IMHO.

I tend to use BP if I can, it would be good to put your car on the dyno to see it's power curve vs a non premium diesel user like myself  :smiley:

I'm feeling that too, but it does feel nice with V-power smoother engine. I'm just so glad I have the GTD now, last year it was the Ed30 270 quid a month petrol bills :shocked:

I did try V-power in my GT TDI mk5 140 and I swear it didnt like it.  Never tried it in the GTD as its like 8p a litre more for me.  Thats £4.40 more per 55 litre tank full.

This was discussed recently in the MK6 forum http://www.golfgtiforum.co.uk/index.php?topic=175028.10
I think the consensus was that diesel doesn't have a higher octane as that is for petrol but it does have additives that are supposed to keep the injectors clean. Thus keeping the performance up.
So probably a placebo effect if you notice a difference on a relatively new car.

I don't know about the current CR models but i really cannot tell the difference in our PD TDI130.

Sorry I forgot about that thread :smiley:

On diesels it's the cetane number / rating that your looking for - octane is for petrol  :wink:

Yeah I know but the higher the cetane is, doesn't have the same effect as the higher the octane is in petrol. Is that right?

Will keep the internals a bit cleaner, but modern cars now all have completely adjustable timing, so really, it's not worth the extra dollar as the new engines don't really need it now.

The effects of having a higher cetane rating should be a better, faster burn giving a smoother more powerful engine.

If you search on the net opinions vary wildly  :sad:

If I get r e a l y bored in work I may do some dyno runs and eu drive cycles using gravimetric tanks filled with both high and normal cetane diesel to see if there are any real world differences.

I've always found that both the Golf and the Audi smoked less and went further per tank on the premium diesel stuff.

I avoid supermarket fuel at all costs as that's just nasty  :sick:  I think the Golf smoked less when the turbo went BOOM  :laugh: :laugh:
