Although diesels stand up to it better (you see trucks doing it all the time, and they still do heaps of K's between rebuilds), prolonged idling isn't good for any engine — just get in and drive it.Quote:

One thing worth getting for a diesel is a mis-fueling device like this. Stops you putting petrol in because the petrol nozzle can't go in.

I think it is the other way around. The fuel engineer from BP said CN and CI are near enough to the same:Quote:

Theoretically, no diesel in Australia meets the VW spec 51CN. Often the local diesel would be near that, but the specification in the diesel standard is lower at 46.
So I theorize than the under-spec diesel contributes to higher soot and DPF clogging.
A cetane improver makes sense. BP Ultimate pre-2010 had a nitro cetane improver and min cetane 50 typical 55, but not since 2010. The highest readily available higher cetane diesel is probably Caltex Vortex with biodiesel (last I looked only in NSW). I saw today Mobil is selling "Special Diesel" - sound similar to BP Ultimate additive package sound like antifoam and injector cleaner at least. European EN590 diesel standard permits a small amount of biodiesel to B7.
I use Morey's diesel smoke killer as suggested by Transporter. It has an algicide, too.
I filled up at a BP but it didn't have an 'Ultimate' sticker on the pump and the lady said she'd find out whether it met Ultimate specs.
is there a 'basic' BP diesel?
Standard diesel is what everybody gets. Ultimate diesel is the same fuel with additives - the product specification mentions anti foam, injector cleaner, lubricity improver, corrosion inhibitor. (But that is a different list from what I remember from the BP engineer who talked about the BP Ultimate launch. I thought there were 4 and one was the cetane improver, now deleted due to potential risk of storage prior to adding to fuel.)Quote:
