Snake oil.

[Polarbear]

As we are talking about cars...

My Jaguar has a 2.2 turbo diesel, 200BHP. Nothing really fancy, a 4 pot engine but goes fine.

The Jaguar owners club recommends using premium diesel fuel with an addition of something like Wyns gold every 3rd tank or so.

Now with petrol engines I would personally just chuck supermarket fuel in and not worry about it but I've never had a modern diesel before (marine diesel engines were designed at the dawn of time ) with all the accompanying electronic sensors and also a DPF.

So car mechanics, is it worth the extra cost of V power and additives or snake oil is snake oil.

The car is running fine and the cost difference is not too bad that I'm struggling. It's just purely to keep it running in the best condition I can.

Thanks!

Had modern diesel lease cars for the past 20 years (Alfa mostly & now a Citroen) - never used anything but cheapest diesel (oh and petrol once* ). I never racked up high miles but do go on the occasional motorway run which helps.

I wouldn't bother unless you are on a diet of short runs that don't burn off the particles**.


* never started, drained by self - ran with some Wynns on initial start back up
** whatever they are

No - just give the thing a helluva blast now and then.
Lots of people buy a diesel because gr8 mpg and then only do city driving which is both pointless and will eventually choke the poor thing.

My last 2 cars have been diesels and they've only ever been run on normal fuel. I give my cars a good fettle every 2nd week - literally foot to the floor and make the thing breathe. Obviously do it away from certain eyes and don't do a simple flat out. 10 miles is good enough.
If you can't do that for whatever reason then try doing a 50 mile non-stop run. That doesn't have to be flat out. Just keep it going and make progress.
I'm lucky in that I can find remote valleys into the hills. Those same roads have some good long hills to make the engine work harder.

My current car, a Leon 184, will gradually choke up but the odd blast now and then really makes a difference.

Diesels? Filthy things, barely one step up from coal-fired steam power and not suited to domestic transportation. If it's not chucking out a cloud of soot when you accelerate or change gear you're knackering it. And if it is (it will be), you're killing kittens, turtles, OAPs and school kids.

Just use a decent quality fuel, I used to use supermarket fuel and never believed the hype about using better quality fuel but in my experience the car runs better on it and gives a slight better mpg.

Stick some magic pellets in the tank.
While yer at it, bung a in few magnets, a rusty nail
and a dead rat and it'll go like the clappers

The additives only result in expensive exhaust gas.

Myself, I would consider adding some kerosene/petrol if I was taking a diesel to climes below -40c

With the cost of high pressure fuel pumps, injectors and DPF, I wouldn't put anything in the tank other than diesel.

Costco only offer premium diesel, my car ran better on that compared to Asdas.
I stuck normall Shell diesel in once and it ran ok on that too.

I live in a city. I have a petrol car for town and a diesel one for the motorway. The bike is more enjoyable than either for beating traffic queues! I cycle but only on cycle paths - cyclists in double file holding up the traffic on a narrow road or solo going slow in town drive me nuts. No horses on the roads ever, please - tracks only . Choose the right transport for the right purpose. Simple!
