What octane rating for Suzuki Swift 1.3 2007. Currently using 95

Sounds like pre ignition Knock....Try going to a Higher Octane Fuel........ Any Octane under a 100, does not work well over 8.5 compression Ratio.......You could retard the ignition timing, a few degrees if you cannot get a higher grade of fuel.............

91 or 95 octane is suitable for 9.5-10.5 ratios ( most engines)
for 12.9 you will find that it runs best on 98 octane
it may be good on 95 octane but generally the higher the compression ratio the higher octane rating
discuss the octane rating required with the bike service agent/service center

what car? 3rd gen swift?
what year?
what country?
what JOB , cam , or spark marks?
or?>
K14B - 1.4 L (1,372 cc) (73.0 x 82.0 mm) DOHC 16-valve - this 70 kW (95 PS) engine is built in China since 2005 (alongside the K12B) for Chang'an and Changhe Suzuki vehicles.

Usually because there is a problem with that system.
Have the computer scanned for codes.

No! the octane rating rating is far too low, even if you are living at over 2000 meters. You should be using nothing less than 95 octane and if you are at sea level you should be using 98 octane. 90 octane is going to damage your engine.

given the make up of newer vehicles, they are designed to run on minimum octane ratings without doing engine damage. 87 is fine.

Measured my 1994 Suzuki Swift primary was 1.3 ohms. The secondary is similar to the above

When you buckle the belt it will push a button inside the latch.
you need to replace the latch and it should go to working.

1991 Swift - 203,000km. It runs excellently and gets 480km to the tank on standard, 550km on Premium (95 RON). Original clutch too, but has just had 2 new front shocks.

Hello Joshdhorz,

The best fuel you can use on your vehicle is any octane that contains at max 10% ethanol.

Ethanol is an alcohol-based fuel additive made by fermenting and distilling crops that have been broken down into simple sugars.

A 10% blend of ethanol and gasoline will not harm any engine or fuel system component. However, the ethanol has a cleaning effect that will remove rust and other junk from the fuel system. This necessitates frequent fuel filter changes until the fuel system is cleaned out.

Most gas stations in our area are set like so:

87 octane (Up to 10% ethanol)
89 octane (Up to 5% ethanol)
91 octane (No ethanol)

Now we do not have 93 or 95 octane available to us here, so I am currently unsure as to what is in 95 octane fuels. In my opinion, I would use 91 octane (No ethanol) for the majority, while adding 87 or 89 octane (5-10% ethanol) ever so often to clean the lines.

I hope this helps you out,

Shadow

Also if you would not mind taking a moment out of your day and rating my solution it would be greatly appreciated. Thanks in advance!
