Reset and try to keep at 2,000rpm. Now my average becomes 6.1L/100km (70% highway, 30% city).
Happy with the current FC.

Nope as I know.

Why not? There's quite a few members using that fuel.

Hahaa sorry cant help myself from LOL.. Better fuel is always better no? Why in doubt?

Carbon depends on luck. Not all direct injection engine kena.

All engines will kena, just how bad/how fast. Can ask those outside workshops after a year or 2 for their experience in opening up the engine. But using good fuel and engine oil will help reduce the deposits formation. Once in a while pump in Shell V Power Racing can be a good start

After warranty over, find a better engine oil to use.

Pinging and knocking is a bit like a lottery jackpot, even though the science of it is well understood, experienced engine tuners will know the fact that sometimes even out of nowhere with low engine load, knocking/pinging can occur. Modern engines (and also the skyactiv engines) have ECU that monitors engine knocking/pinging. It will advance/retard accordingly to prevent damage. Skyactivs in US can run on equivalent RON90, so RON95 will absolutely have no problem.

I don't care whether it's 95 or 97 as long can pakai. Even Blaze 100 also can pump

Driving style matters as well. If you're always on short drives where the engine doesn't get hot enough, you're more likely to get deposits. This article discusses it

I remember seeing in another forum that there are some carbon buildup in fairly new engines but not enough to cause harm yet. In those cases, they talk about installing an oil catch can to avoid engine oil vapour circulating from the positive crankcase valve from getting into the intake manifold.


Yeah the engine has knock sensors and automatically retards timing. That said, once the care ages, you'd probably hear some knocking now and then. My old City idsi was ok all the while and then earlier this year, on a really hot day I heard knocking. And knocking doesn't really depend on revs but more on engine load.

US Octane ratings are different from ours. Number is lower than ours.

I prefer BHP for the euro4m rating.

I understand that, RON90 is about equivalent to 87 Octane rating.

Can't compare because the engine may be tuned differently for different regions. But using RON95 here has absolutely no problem.

Yeah missed the "equivalent" in your earlier post. That said, their's are rated 155hp@6k rpm with 13:1 compression ratio whilst ours is 162hp@ 6k rpm with 14:1 compression ratio. Looks like they backed it off to cater for Regular fuel in the US.

Not only the tuning, hardware also got some difference, the piston is different design from the higher compression version.

Yes the higher compression is from the piston. Tuning isn't limited to electronics.

to those who wonder how it looks like on ur mazda 3

Looks good. Any impact to steering tilt & telescopic adjustment?

How much is it with installation?

Any member here tinted with skytint? Did you guys remove and replace with new tint or add another layer solar film on top of it?

Highspec & GL (selected colors) - Fast Delivery !!

HB is going for a huge PROMOTION !!!

Yes. Is your car with or without nav? It's a risky tweak though; if you're iffy about warranty better avoid tweaking your mazda connect.

Hello guys. Recently im facing with this istop problem.

Fuel economy monitor shows that my aircond and engine is already on ready mode for istop. but battery is still un-ready.

Asked some forum-ers. they told me to put on seat belt. i always put on but the problem still doesnt solve.
