Ive put so much fuel in the last few weeks i dont know where its all going?

i have no proof but as you all know, you know your cars pretty well and you can tell when that petrol gage is going

down more then often...

So today i popped to the garage to check the tyre pressure, 20p per 2 minuites... air used to be freee!!

front tyres 27psi

back 35psi

Think the max is 50 on my tyres, pumped them up and set off felt like a new car but surely something like that couldnt make such a difference for me to notice?

what else could it be guys!!

Thanks!

dear me, i just have mine at 2.0 Bar at all corners , your right though i don't think Tyre pressure would make a noticable difference unless they were really low.

First of all those pressures are all wrong. I hope you set them at around 32 psi front and 30psi rear. That's correct i think for your model but fuel flap should have the sticker inside to confirm but there listed in bar which works out 2.2 front and 2.0 rear.

Also you will find with the current cold weather cars take a bit longer to warm up and also cold dense air = more fuel to go into the engine to keep the air/fuel ration correct.

Overall things like tyre pressures and serviceable items like spark plugs and air filters etc do affect how well a car runs.

What sort of mileage is your car on?

Yea, ive had it about a year and a half but havent had it serviced myself.

I dont use it that much and with 45k on the clock you can tell.

Could be due spark plug replacement as these are due at 40,000 mile on the engine you have.

Can i ask why you put 40psi in your tyres? Do you always have a fully laden car? If not you will be wearing out the center of the tyres too quickly due to over inflation and also you run the risk of making the car unsafe due to less tyre surface in contact with the road. Go by what VW gave put on the sticker in the fule flap they spent many years coming up with the pressures as the best optimum for the car and you just putting in 40psi could be doing more harm than good.

ive always had my cars on around 40psi and had no problems so far? no crashes or anything? handles better with pumped up tyres in my opinion.

You think its unsafe to have your tyres pumped up that much?

been fine for me in my 3 years driving with no points, crashes or anything

on the tyre it reads max 50psi.

recently had 2 new front tyres about 2 months ago.

cars fine, your right people, plugs and filters to be changed i think!!

THANKS

My TDi 130 suddenly started using about 20% more fuel. Took it to a specialist who diagnosed intercooler seals. I was a bit doubtful if this alone would cause such a drop but they replaced all the seals at under £100 (about £28 for the parts) and it was straight back to 50mpg plus. Worth considering!

That 50psi is the absolute max pressure, not the advised pressure. You WILL wear your tyres out in the centre of the tread if you use ANYTHING over the recommended pressures without a heavily loaded car. Also, your braking distances will be longer and traction lower. Use the recommended pressures, please.

Can i ask at what mileage the spark plugs on a 1.6 8v engine should be changed?

Cars done 97k and av had it two years now, got it with 72k on the clock

I think that usually plugs are changed at 40k, but I change them at 20k and notice quite a difference in the engine.
