yes, euro rating covers many things but mainly focuses on emissions, the higher the euro grade the less emissions it produces.

while emissions are good for enviroment, what does it mean for your engine?

take one category that euro grading focuses on : sulphur content.

sulphur in the fuel when combusted produces sulphur dioxide. Sulphur dioxide when mixed with water produces sulphuric acid. This acid is what we call 'acid rain' in environmental terms. Now this sulphur dioxide also mixes with the water in your engine, water that comes from the air and as by product of combustion. Because no engine is 100% sealed in the combustion chamber this acid eventually gets into your engine oil and starts degrading it. Since you cant see or feel its effects you normally dont care about it, but it's there and it's eating away at stuff inside your engine

so. Euro 3-4 fuels are good for any engine, not just for the enviroment

This techron thing is DIY

I suggest you do the Liqui moly jetclean tronic system in authorized workshop and the results even better

I thought that is more on decarbonizing and cleaning the throttle body?

i believe it also able to clean the fuel tank with that cool pump machine. Did not tried on mine but my friend did it.

Because it is dangerous to DIY that techron in my opinion because the tank must be almost used up to have better result as stated on the bottle. Otherwise it is pointless

"  To use, pour the entire bottle of TCP into a nearly empty fuel tank and refuel with up to 45 litres of petrol "

Trust me you do not want to risk going nearly empty fuel tank just for this, its very risky later will also cause all kinds of high temperature results or fuel tank too dry etc.

Really want to do it , ask a experienced user/workshop.

yes you're correct by saying going nearly empty fuel tank.. may cause fuel pump overheat or so on.  but this has nothing to do at all with using TCP.  you can just pour in TCP at blinking fuel indicator level, or last bar, or last 2nd bar..  who ask pour TCP at dry fuel tank??

why not pour TCP when the fuel tank is full you ask?  because pour in TCP first, then only pour in fuel can ensure good agitation and mixture of fuel and TCP.  if you can poke a stick into your fuel tank pusing pusing a bit, then is okay also.

so just use it normally when you go refuel lo, no need purposely wait till too empty.

Brothers,

So add this addictive to near empty tank, (meaning wait for fuel icon?), after that pump in full tank? Use every 5,000 km?

Sorry for noob question. Never used addictive before.

I believe this Techron Concentrate is a  fuel system cleaner with added RON value booster.

no RON value booster i believe (or it's too little to be noticeable), the redline one should have though since they claim as such.

There is no way to make the fuel feel any better than booster. Cleaning agents does things differently.

well if the injectors/combustion chambers aren't clogged, supposedly there would be better fuel delivery and better combustion.

but of course it could be all placebo anyways
personally as per my 2 feedback, not much difference.

but hey, smoothness aside, most people are using it for the peace of mind (keeping the fuel system clean) anyways

I still facepalmed hard at those stupid idiots comment at Paul Tan's post.

"If Caltex is going to give warranty to my engine then I will use it." - Oh crap, I don't know I have been driving a broken engine all way long 

"Useless. Just pump V-Power and tekan. What is this Techron? Never heard before." - 

you know, i wonder what's the fuss with vpower, when i can just load up 97 petronas/bhp and a couple more bottles of octane boosters and then maximum ignition advance

sadly i can't quite do that *yet* with my inspira lol... else it'd be pretty damn fun
