Hi newbie here with a quick question
« on: December 13, 2016, 09:55:41 PM »
Hi I recently (August)grabbed a bargain  nabbing myself a 2006 Mazda 3 1.6 petrol katano for just a grand .
Very happy with it so far with one niggle  Does it have to run on super unleaded?? If I use 95 Ron it hesitates at about 1700 rpm under load , if using  tesco momentum 99 it doesn't . So I use the momentum it's not much more expensive and the car pulls smoothly . I just wondered if Mazda are designed to run on 97+ octane ?

Ps
Are there any common faults I should look out for ?
Many thanks for your time .
Nick

There's no specific requirement for high octane fuel but if it's happier on it and you don't mind paying the extra then crack on. Fairly sure most run them on 95 without issue (so you may have a little problem somewhere), can't speak from experience as mines always been on 99 while I've had it.

Mechanically the petrols are tough, rust around the rear arches and sills can be problematic. It's at the point where old age and previous owners cutting corners could potentially bite but there are no common failures.

Hi . Welcome to the forum.  I've got  2004  Sport now on 112k that has always been fed 95 octane. Behaves like a 2 year old, still out running a jumped up Focus ST on the A1(M) today.:)
There is no specific need for higher octane as the engine was designed to run on 95. But as Steven has already said, if you believe it runs better on 99 and you're happy, then just go with it.   
Look at life through the windscreen, not the rearview mirror.

Thanks to you both , yes it drives like a dream on the 99 but has quite a pronounced hesitation at 1700 rpm on 95 .
I suppose it could do with a set of plugs maybe?
It's got fsh but high miles on 147000 , very quiet though , no rust anywhere . Hope to get a few years out of it as I do about 9000 A year .

Spark plug intervals (provided they are the same as my gen 2 1.6) are 6 years or 75k miles, you could be due on both counts.
