Hello, I'm new here.
Having just purchased the above vehicle, i am surprised at it's lack of oomph. Can any one recommend the steps i should take to get it as good as it can be. I've changed the plugs and checked the air filter, I'm awaiting delivery of a cat cleaner and a new seal for the filler cap. I am also surprised to find so little information on replacing the fuel filter. Have any of you replaced it? Did the new filter make a difference or does the fuel filter for the petrol variant last the lifetime of the vehicle?
For years now i have only owned diesel cars my last one being a 2.0 tdi golf so this petrol journey is new to me.
Thanks. In anticipation of an inciteful reply.

mmm,the 1.8 in the Insignia is (shall we say) a little lacking in go,
do the things you plan but i doubt it'll make a lot of difference,
there's not a fuel filter in the system,just a coarse gauze in the fuel tank that in theory will never need cleaning.

You bought the wrong car, the 1.8 is to small for the size of car,. When the vec b had the z18 at 125bhp was just OK then it got 140 when put in the vec c but still lacked get up and go. Small engines in big cars are a waste of time poor mpg and get up and go.

You can't compare 2.0 diesel with 1.8 petrol. Had 2.0 tdci in focus and it was flying, when working (got rid of this c..p last year).
I have similar engine in our Zafira - (you have A, I have Z), and when I was switching the cars the difference was enormous.
Bought Scenic III 1.6 last year and it is a slow cow compared to Vx 1.8.
So maybe there is no issue with your car at all.

However, it would be a good idea to do the starter pack: the cam set, drive belt, air and oil filter, oil.
Personally I've never changed the fuel filter in any of my petrol cars, and had a quite few of them.

The car has 100 bhp per tonne. It's not going to be a rocket ship, but perfectly acceptable power to weight ratio for day to day use. Be cheaper to lower your expectations and increase your 0-60 time than change car.

I have had cars with a lot less power than 140bhp, it doesn't sound too shabby to me! :LOL:

As a driver of an 84 BHP Astra G, it's what I do. A slightly more mellow approach to accelerating needs to be adopted. I cruise along quite happily at 60/65 and acheive great mpg. Whilst not exciting, it is certainly a much more relaxing way to drive and suits my car well. I suspect it would your Insignia.

I could see myself in an Insignia 1.8. Fine looking car. May not have the grunt of that lovely 160bhp diesel with its huge torque reserves, but then again it's got a lot less to go wrong. :)(y)

Yes it is a good looking car and i agree there are different ways to drive. You speak a lot of sense. Thank you.
