...used a Jet petrol station on saturday (95 ron)....i very rarely use it i have had 'bad' petrol from there in the past...but this was in my old punto so wasnt that much of a concern... however with the octy it was diffrent story!

saturday night going down the A1 practically lost all boost...only boosted to 5 psi.....turned off the car for about 1 min started it and the boost was back but only to 15psi usally i get up to about 19psi... the car ran like a fat man with asma until i re filled at my trusted shell garage (95 ron).... coudl there be any long term damage?

also i have heard of people loosing boost pressure and turning there cars off for 1 min and then every tihng is fine... but can not remember what the cause was.... this is the first time it has happened and i put it down to 'bad' petrol.

Had exactly the same problem. I persoanlly don't think its down to the brand of petrol. Its probably a dirty MAF sensor. Do a search to find out how to clean it. Had mine done and its been fine since. I usuauly run on 98RON when I can find it, the loss of boost has happened twice, once with 98ron, once with 95 and both were different brands.

Joel_vRs:

How are you measuring boost pressure?

It could well be Jet to blame, we had the engine go on a 6 month old scooter after filling up at Jet.

cunningly with a boost pressure gauge

In their defence because there are always 2 sides to a coin. Filled up with Jet Diesel Plus in Belgium a few weeks ago

i had 95 ron in my car when it was chipped, it kept pinking and ran rubbish till i filled up with super. never missed a beat apart form a loose connection on the boost controller

TBH im sure is the garage itself dirty tanks maybe even though its Jet at the moment when i have had dodgy petrol from there in the past im sure it wasn't Jet..
