Re: FIAT PETRA (SIENA) 1.6 Petrol maintaince advise

There's no easy answer.
Changing at 1000 rpm is way to soon, but 4500rpm is far to much!
As a rule, I change at no less than 2000 rpm's, and max. somewhere between 3000-4000 rpm.
High temps. and lot's of stop and go traffic is hard for any engine.
Again, keep the engine in perfect tuned condition, use quality oil and fuel, and keep an eye on tire pressure.

Re: FIAT PETRA (SIENA) 1.6 Petrol maintaince advise

The Fiat WCP 178 range ( Palio, Siena, Petra, Strada etc.) are not known for their fuel efficiency, I'm afraid...

(WCP = World Car Project #178 ).

Re: FIAT PETRA (SIENA) 1.6 Petrol maintaince advise

Agreed its not known for their efficiency but what i have been getting is just too bad

Like in your case its 12

I went through several other pages on internet and al. Suggests to change at rpm where max torque is produced. So will follow 3000 rpm limit and see how it goes
Thanks

Re: FIAT PETRA (SIENA) 1.6 Petrol maintaince advise

Last time the reserve light came, I immediately filled worth 500 INR which is 6.4 ltrs of petrol.

I know this is not the perfect way to take out average, that's why I have mentioned it as approx.

It ran for 43 Kms before the reserve light came again and I immediately filed up fuel worth 500 INR

So that equates to 6.71 kmpl with full ac useage. This is around 1 kmpl more then last time , when my brothers used to shift gears at lower rpms (below 2500 to 2000)

Traffic conditions were same all the time

Now the car has run for 55 Kms and still the reserve light has not come but my guess is it should light up in max 6 Kms more

But still that equates to average of 8.60 which is really a marked improvement

Maybe some others can try the same thing and see if benefits them w.r.t. To fuel economy

Re: FIAT PETRA (SIENA) 1.6 Petrol maintaince advise

Most likely not.
Fiat uses 4X98 tread pattern, which is unique for Italian cars.
Also the centre hole has different dimensions from any other wheel.....
You can use any wheel specially made for Fiat, Alfa or Lancia, that's it.

Re: FIAT PETRA (SIENA) 1.6 Petrol maintaince advise

New shoes for my car

Searched for pirelli but supply is very erratic here in india so chose for michelin

The tyre name is michelin xm2

The xm2 is not a sporty tyre but comfort oriented and apt for road conditions here in bombay so chose the same as my car is never driven to the limits

Re: FIAT PETRA (SIENA) 1.6 Petrol maintaince advise

Why did you choose 185/65-14?
Because of the bad roads where you live?

Original size is 175/65-14.
So 185/60-14 is the next size.
185/65-14 sidewalls are a little higher, giving a less sharp but somewhat more comfortable ride.

I don't think you will notice much difference though.

Michelin is of French origin, and amongst the best tyrebrands money can buy.

Hi peter

I knew this was coming

The tyre guy asked me specfically if i drive the car hard and my reply was obviously a no

I explained him that my car is mainly used inside city and so cant see high speeds and has to encounter sometimes very bad roads

So thats why 65 profile was chosen then 60 with 185 mm broad tyres. I was told that i will have a speedo error but i was ready to live that for thay extra bit of protection.

The rim size was big enough to accept the size

Michelin tyres are one of the costliest in india and xm2 model is one of the best all rounder tyre (mainly for bad roads and comfort oriented) money can buy in india

There are other tyres which are more rugged and can take worst of roads but ride quality and grip on them go for a toss

So overall this is a very balanced tyre

Hopefully on the weekend i am going for a 200 km drive with my friend and should be able to post my take on the tyres after the journey

But a proper conclusion can only come after using the tyre for more then six months

Next up is full body paint and seat modification as under thigh support is very bad and overall foam used is too thin

No time frame to complete the jobs mentioned. Will be done as and when time and pocket permits

Already i am being termed as a foolish guy who is putting so much of his hard earned money on a ten year old fiat

but i totally disagree with them
