Low grade fuels have negative impact on Nikasil coated engine liners and components. Nikadil coating is a technological advancement offering low friction and heat with low tolerances. But even German engineers got it wrong with durability with high sulfur fuel.
The 1.5T uses a special low friction ion coated piston rings for the same purpose. It's long term effects with low grade high sulfur content fuel remains to be seen.
There are many types of combustion coatings available in the market and Nikasil is just one of them. Are you sure this Honda engine is Nikasil coated? If yes, please share the source link, i'm interested to read it.

Some basic info on the various fuel standards FYIEuro 1 – 1992 (sulphur content 2,500ppm)
Euro 2 – 1996 (500ppm)
Euro 3 – 2000 (350ppm)
BHP RON95 – 131 ppmEuro 4 – 2005 (50ppm)
Euro 5 – 2009 (10ppm)
Euro 6 – 2014 (very low)
Ppm = quantity of sulphur (mg) in 1kg of fuel
Negative effects of Euro 2 fuel: 1) High sulphur content produces significant amount of Sulphur Dioxide resulting in Sulphurous and Sulphuric Acids
2) The presence of the sulphuric acids cause:-
3) Contamination of crankcase oil / lubricating oil
4) Corrosion of engine components / parts
5) Catalytic converter is damaged and is unable to neutralise pollutants ( CO, NOx & Unburnt Fuel )
6) SOX contribute to the high emission of particulate matter.
7) Decreases the
cetane number resulting in incomplete combustion and the formation of soot.
8) Injector tips are obstructed with the formation of soot.
9) Injection spray pattern is altered resulting in incomplete combustion.
10) Significant reduction in the lifetime of the engine.
11) Increases maintenance costs due to frequent replacement of engine oil and servicing parts
Benefits of Euro 4 fuel: 1) Insignificant formation of SOx /acidic compounds
2) Decrease of particulate matter/Black smoke
(if petrol engine got black smoke, straight masuk kilang overhaul)
3) Reduces output of Oxides of Nitrogen
4) Increase
cetane number result in complete/efficient combustion
(see comment below)5) No unburned fuel
(not relating to sulfur PPM but the effects of inefficient combustion)6) CO is easily converted into CO2
7) Engine lubricating oil less prone to acidification
8) Reduces engine component corrosion
(if engine oil not up to temperature due to frequent short drives or a lot of stop/go traffic condition, water content will chain up with the sulfur elements creating sulfuric acid. Driving up to temperature will cause the water content in oil sump to evaporate)9) Increase of lifespan of catalytic converter
10) Engine less noisy
(this one not applicable)11) Engine develops more power
(very unlikely, marginal at best)12) Increase of lifetime of the engine
(debatable)13) Increase in fuel economy
(true for diesel, for petrol is more likely due to better additives used in RON97)14) Reduces maintenance cost due to insignificant contamination of engine oil and service interval can be increased
15) Eco friendly fuel
(if lead footed and always traffic jam, not much difference lor....)We should be getting Euro 4 RON95 fuel in a couple of years which isn't too far away to cause significant detriment to our car engines using current Euro 2 RON95 fuel. But in the meantime, I would strongly recommend BHP RON95. It's the best RON95 fuel in the market currently. Some batches of BHP's RON95 fuel was even tested to be only 12ppm which is almost Euro 5 standard.
No offense, but i think your facts are more applicable towards diesel. Although some of the facts are still applicable to petrol engines.
Cetane ratings are only applicable to diesel fuel. Unlike RON rating, higher cetane rating can derive more power to the engine.

Actually if they are averaging 131ppm vs 500ppm Euro2 spec, I would consider that is quite good. Too bad we don't have consumer or motoring association carrying out random sampling to inform us of the industry average.
I'm also a BHP user, unless its too out of the way. One nice thing about the bigger fuel tank and increase fuel efficiency of this car, now I can get by only fueling up over the weekends and dont have to fill up at other random stations
The PPM average was true at that time (which was 3 or 4 years ago), but no one go follow up to double check is it applicable now. Anyone wants to give sample to SIRIM to check? I know they can.

I'm finding that the Conti tyres are quite good leh. The more I drive on it, the better it is - it's either that or i'm getting used to it's flaws already

Will wait for PS4 to launch before changing
QUOTE(hihihehe @ Aug 2 2016, 11:17 AM)
i'm not sure in tires but the tread seems like wearing out quite fast
my next replacement will be RE003 or PS3 but have to depends on my budget. dont think PS4 will come any soon
Sudah unofficially dijual, i dah tanya
