Forgot to mention this is the oil:

Castrol GTX Diesel 10W-40 B3

Castrol GTX Diesel is designed for today’s diesel car engines. It’s more than just oil. It’s Liquid Engineering that fights diesel engine problems that your engine faces every day, like soot and harsh deposits.Why is this important? Because soot and harsh deposits can make the oil thicker, blocking oil ways, causing wear and decreasing performance.

Castrol GTX Diesel provides superior engine protection

    * Superior cleaning power to maintain engine performance

    * Reduces the build up of harsh deposits

    * Helps prevent oil from thickening and keeps it flowing freely

    * Outstanding diesel engine wear protection

    * Suitable for Inter-cooled and Turbo-charged diesel engines.

Oil companies spend millions of pounds every year designing various grades of oil for various engines.
Diesel oil is designed for diesel engines, and the same goes for petrol.

Yes you can use oil designed for diesel engines in your petrol lump if you so desire, but don't be surprised when you get shafted with a big repair bill after a very short period of time.

Thanks very much

petrol explodes, diesel just burns. Diesel oil is designed to collect soot generated by diesel, with petrol there is no soot. (well not as much as diesel anyway)

Just buy petrol oil its not exactly expensive from Vx at £9 for 5L

Hi
Is this diesel oil intended for diesel engines with catalytic converters, if it is then its probably okay for petrol engines too, but if its not okay for cat diesels then I would say its not suitable for cat petrol engines either.  None cat oils contain ZDP as a friction modifier and this can eventually poison the cat.

I use VX recommended semi 10w-40 in my TD, the same stuff most of you put in you petrol engines. Should I be using a diesel oil?

Castrol GTX Diesel complies with ACEA A3 as well as B3, which means that it meets the requirement for GM petrol engines too.

The only real difference is likely to be the detergent additives that are added to the oil (the main difference being mostly marketing, of course).

If the engine has shown signs of neglect to oil changes in the past (e.g. manufacturer's recommended intervals ::)) I would recommend a couple of quick changes at 1000 mile intervals in case too much sludge gets loosened by the detergents but then I'd say use it.

I would, if I had a free supply of it. :y

Other than a flushing agent, not sure I'd even put any Castrol oil in the lawnmower, let along any car ::)

I'm no expert but have to agree with the Boy on this one.
Heard very bad thing on Castrol oils from many mechanics in the last 10 years.

Yeah - I was suprised when I was handed the same oil across the counter when I switched from TD to V6.

I'd to buy oil at the motorway services yesterday as the low oil level warning came on a couple of times on long slow inclines - caravan on tow! Castrol was all they had  :-? and it was as expensive as a gallon on Vauxhall's oil on TC ....... still cheaper than another engine though  ;) :y

You can use petrol oil in diesels but not the other way round.
if you get used diesel oil on your hands it's bugger to wash off where petrol washes of more easily so just think what is does to a petrol engine.But come to think about it, it will leave a thin coat of oil  on the bores which might be a good thing on a high mileage engine. :-/
