GTD and V-power ?

[Steve30]

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?

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 

[Steve30]

Doc have you tried the V-power in your's ?

Price makes me say no chance.

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

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.

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

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