Proof
The evidence behind what we say, and where it came from. Supplier material is labelled as such; a co2ox test result carries the engine, load, analyser, and date it was measured under. We measure on your engine under an agreed protocol before we make a claim about it.
See it for yourself
Reading the evidence is one thing — watching us measure your exhaust before and after is another. We can run a demonstration on your engine, under the same protocol these documents record, so the proof is yours and not ours.
Documents available on request
We don't publish a document here we can't stand behind. If you'd like the current supporting material for a specific engine class or claim, ask us and we'll send what applies to your case.
