Decoke after how many kms, sir? What brand & octane fuel used before & after? Thanks

Sorry I would need to check the records to get the exact info. As far as I remember was initially using Petron Super XTRA Gasoline (91 RON) for the first 5k then transitioned to using to Petron XCS (95+ RON). It initially felt like it had more go for a few thousand kms - but when the check engine light started flickering on it started to feel sluggish. Any reset couldn't remove the light. This happened between 5k to 10k kms (within the first year or so).

I'll double check the records when I have the time. Foggy memory since this was a few years back already.

Though in reality still perplexed with the dealer recommendation to follow recommended fuel octane level since the manual clearly stated it should be able to accept a higher level. Some fuel quality thing perhaps? They can't even explain why. Anyway just followed it since it ran just fine on regular and didn't want any more headaches.

5-10k w/in the 1st year is really premature for decoking. Were you filling up at certain preferred pumps or random? What was done? Walnut media blasting on the head? It's odd that they'd easily point to octane. Those tests on PH petrol samples jp conducted prior to the launch of the Sky 6 & cx5 must've pointed to something that made em favor a certain brand . I've been on Shell since day 1 & lucky to have our neighborhood pump along my daily route a km away. Started w/ regular & have long been on premium. It's been the daily driver the past 36months.
Hope some more light would be shed on this to help everyone. Thanks for sharing, Neutron sir.

do you think the occ mods will cure carbon deposits for these direct injection skyactiv engines?

The logic is there, much like old school engine breathers.

I also heard of stories of people using higher octane having problems. My friend told me it has something to do with residues from the additives introduced to the higher octane fuel.

Would it be possible that some labeled premium are just regular spiked w/ boosters? ....what type is the question. Might be wise to stick to the endorsed brand. Real premium should not rely on octane boosters. Ethanol is 1. Hygroscopic. I hope none of the oil companies are adding more than what the law requires em.

91 and 95 have different base fuels - as in they're two different products in two different tanks in the depot.

91 is RON 88 plus E10, 95 is RON 92 plus E10. Sometimes, when 91 is out of stock, oil companies sell 95 at the price of 91 to the gasoline stations, but never the other way around.

In terms of adding too much ethanol, that's highly unlikely because ethanol is much more expensive than gasoline, so going past the 10% government mandate is not profitable.

Of course, I can't speak for generic stations, who are notorious for infusing corrosive methanol (cheaper than gas or ethanol). Most generic stations sell clean fuel from the big brands themselves, but there are a few rogue ones out there.

Good to get it direct from an industry insider. Thanks for clarifying, jut sir.
I spoke to another just now....he mentioned the practice of rogue ones who mix their stocks w/ smuggled fuel. I personally know of an operator who got caught. Who knows what type of maintenace the delivery companies do w/ their truck tanks. Is this still common today, jut sir?

You mean the fuel lorries? For the big brands, they keep a very high standard for their trucks. Man and Volvo trucks are given preference, with strict standards for their Transbilt tanks.

Generic distributors have much shoddier truck quality, but the real watchout here is the condition of the underground tanks and pipes of the station. This is where sediments usually build up, this is what's prone to punctures and leaks. Again, well-maintained stations adhere to strict operational standards, but this is not the case for all.

From experience, even among branded stations, operational discipline is not the same across all branches.

On the question of people mixing smuggled fuel with regular deliveries, this is still prevalent to this day, especially in more rural towns where people are less sensitive to fuel quality.

The usual case though is that, for example, a Petron branded station gets 5 deliveries in a month. Out of the 5, he'll get 4 from Petron - the last one, he'll get from a generic wholesaler. That wholesaler might be getting from Petron too, so quality isn't compromosed. But there are some wholesalers who mix methanol, get from "pa-ihi", etc.

Hard to tell for an ordinary motorist, but general rule of thumb is that most well-maintained branded stations also have operational discipline and integrity. Of course, there are generic stations that offer good quality fuel, but it's a case to case basis.

So many holes here. It's comforting to know the operator & maintenance contactor of the pumps I regularly go to. The latter prompted on the reputable ones.
Appreciate the 1st hand input, jut sir.

Mazda's sold in North Amercia aren't made in Japan (CBU) right? Maybe the vehicles mentioned in the article are for those customers only?
