Supermarket Fuel vs Premium Diesel

I have a diesel pickup, the one I have, has a problem with the DPF blocking and damaging the engine. I run on premium diesel from Costco and so far no problems. I believe the cleaners in premium diesel help. Even if I'm away from Costco, I buy premium fuel. I hope I'm not wasting money 🤞

Does everyone think the delivery vans and courier vans all run on premium fuel..😆

These vans are thrashed every day and still do 300-500k, and that’s what most of us drive, A delivery van in disguise.

The best thing you can do is give your van an Italian tune-up every 3rd tank full…👍🏼😎

Oil refineries are quite big obvious things, none are branded Tesco, Sainsbury's, Morrisons etc, so obviously it's all coming from the same places!

I worked with petroleum vehicles and Tesco Morrison’s Sainsbury’s all comes out of the same storage tanks

Both my Freelanders had to have new EGR valves at about 50k miles, independent repair guy said:
1 never use supermarket fuel
2 every 4 tanks treat it to premium branded
3 give it a good thrashing regularly
4 this will stop things sooting up

Don't know if he was right, but that's what I'm doing on my new van, especially as we have diesel heating and it might stop that from gumming up ( give that a good full throttle burn occasionally as well).
Years ago I had similar problems with a Saab and was given the same advice which I’ve followed ever since and it appears to have worked, over 60,000 more miles of driving before getting a new car. Only 16,000 on this motorhome though at present.

As we are running the latest Transit based motorhome , I'm hoping that premium fuels with their additives keeps it oit of a garage, but in my old Volvo XC 60 I put in the cheapest diesel I can buy and it's done 80 + thousand miles never missed a beat.

Here in France we fill my V8 3.6 Range Rover Sport 250k, my wife DS5 1.8 170k and our Fiat based Burstner Motorhome 40k with supermarket diesel and we’ve never had a problem. I don’t believe there’s any difference in quality unless you want to. All these so called experts usually have a vested interest. If you constantly pay extra for premium diesel you must have money to waste.

Ive always used supermarket fuel only 4 vehicles which includes my now 30 year old Hymer with 345,000 on the clock which has had diesel heating for the last 8 years (Ive had it for 25 years) - still has the original engine c including pump and injectors with never a problem!
