Supreme average is 118p litre and supreme is 131p litre
So a 65 litre tank is £76.70 vs £85.15 = £8.45 difference.
Diesel Eco power max is about £13.00 a bottle and in theory you will treat 10 tanks at 50mL a go.
The difference for 10 tanks of supreme would be £84.50 vs £13.00 for a bottle of millers.
Assuming similar benefits it is still extremely good value if you are a supreme diesel user.
Even if you double dose the Diesel version which is suggested as possible on the package it is still a huge saving of £42.00 over 5 tanks.
Similar savings made on petrol version.
Edit: this is the cheapest I have seen it for a while £12.25

Supreme diesel is a massive waste of money.
I have no connection with Millers at all but trust it and use it religiously now. It saves you a lot of money and makes a difference which is easily noticeable in my Bongo.
As time moves forward I think we could all help each other out on the bargains.
