Diesel & Fuel Guides

Straight answers

The questions we actually get asked

These guides exist because the same questions come up on site, week after week. How long will the diesel in that tank stay good? Is it safe where it is? Do we really need AdBlue, and what happens if we run out? They are fair questions, and most of the answers online are either a sales pitch or a wall of chemistry.

So we have written them the way we would explain them standing next to your tank — plain English, no jargon for its own sake, and honest about the bits that depend on your situation. If a guide raises something you would rather just ask about, talk to our team.
