my car has bad picked up a pinging when it goes past 4500RPM

I use BP ultimate in it, i have had it to a local workshop who had it all day and said it will have to go back when they can figure out what is causing it

They believe if anything it may be an aftermarket 02 sensor that isn't working with the standard ECU, anyone got any other ideas what may be happening as it started it out of the blue one day while driving to work.

nah i haven't done anything to it yet. As far as i was concerned when i bought it, it was all stock standard except the HKS airfilter now i find out it has a aftermarket turbo dump and oxygen sensor. they checked all the mixtures and said that they were all correct

could be a bad batch of fuel. try some good octane boost like nulon pro strength. if that solves it then wait and see if it still does it on the next tank of fuel. if it still does it then get it looked it, if it doesn't come back even after a few more tanks of fuel then it was just a bad batch. and make sure you don't put too much octane boost in as it can actually lower the octane.

mate of mine is a mechanic and he had the nulon rep come through work and he was asking him about the octane boost. the rep had an octane tester with him so they did some tests. at 50% strength it went by only about 2ron, at full strenght it went up by 6ron, and at double strength it dropped by 4ron.

      Import insurance in 2025

      And that's a massive problem, because deadshits will deadshit and give you false details. At least in these days of mobile cameraphones, it is trivial to take photos of any ID they are carrying at the same time as the 300 photo extensive documentation of the state of the vehicles that I recommend even for minor incidents. And you get photos of the person's face, any visible tatoos, etc etc, while you're at it. Then you try to avoid mentioning that you're fully capable of making explosives of various power levels and will wreck their shit if you are forced to hunt them down.

      No, I don't remember the exact reasoning (was 20 years ago!) but the cops didn't end up supplying it to us either. Actually my mother went through a similar thing recently where she was hit when stationary, flustered and didn't get address (she got plate details, name, phone and insurance company, but not address). Person who hit her blocked her number and their insurance company (naturally) would not provide any details. Her insurance company also required her to pay the at fault premium because she did not have the address, cops did not help as it is a minor civil matter (they said their only course was if the other driver had left the scene of the accident without providing any details). She only ended up getting that refunded because they happened to be insured with Suncorp and she was with APIA so same company owners. For some reason the address is critical in insurance companies recovering money from the at fault party

      If you're driving something like an R32 through to R34, no chance of meeting Euro4. Euro4 came out in 2006, and car manufacturers back then were complaining how hard it would be to meet those regulations. Not a chance a vehicle 10 years earlier is going to be compliant.

      I presume it would take more than just slapping a big modern catalyst on the exhaust? It's interesting though, looking at the old sales brochures and listings it does not mention anything about emissions. No one cared.

      Yeh nice, looks like their part of keep it reet? Will have to swing past. I'd much prefer someone actually look at my car and custom make a part, then get a generic part online and hope it works.
