Volvo D5 ervaring met Ultimate diesel:
I've been using BP Ultimate Diesel in my tuned Volvo D5 for the past 10,000 miles and thought I'd post some comments on it.
Firstly - the cost. Most people are taken aback that I will pay an average of 4-5p a litre over the top of regular diesel. But on an average fill up of 55-60 litres, this only works out as less than £3.00 per tank! Hardly a lot, is it?
The engine runs a LOT smoother at idle, much less diesel clatter. On acceleration, the engine produces a much more linear feel to the acceleration. I wouldn't say it has any performance benefits, but it just makes the car a bit more enjoyable coming from ultra-smooth petrol models previously.
It seems to have given me slightly better fuel economy. Only slightly, though. On average, I was getting about 44-45mpg running regular diesel. Now I'm getting an average of 47-48mpg (calculated - not trip readout) for the same type of driving. This gives me an extra few miles per tank but probably not enough in itself to make up the difference in price.
BP Ultimate contains a variety of additional additives that are supposed to clean the engine and do a variety of other magical things. Can't say for sure that these are working (?) but the engine doesn't produce any black smoke, even at full throttle - and thats with the car tuned too.
I was forced to put in a small amount of Shell Diesel Extra a couple of thousand miles ago, and the car ran really roughly and produced quite a noticable cloud of black smoke upon start up. In addition, the fuel consumption was back to around 42-44mpg. Once I switched back to Ultimate order was restored and the mpg went back to 47-48mpg average.
I'd definately say it was worth it, and I won't run anything else in my car now unless I'm absolutely forced to!
