Your injectors can clog up due to bad fuel but I dont know about them physically breaking because it.

I only ever use BP Ultimate, or if I cant get BP I use Mobil Synergy and have never had a problem with either of them, I have used Caltex and Shell in the past but my engine didnt like them as much (especially shell), I got less Km's from a tank and it felt sluggish and unresponsive, the engine pinged few times at high revs while using Shell.

I have a bit of a bias opinion though, my car has a Power FC computer and 550cc injectors (along with some other goodies) and it was dyno tuned using BP Ultimate.

Agree with Bullet. I make special trips into canberra for BP Ultimate :) and if i cant get that then Mobil 8000. There was some testing done (am looking for the post on the forums) of the major petrol companies (BP, Shell, Mobil, Caltex) to show the RON of their high performance petrols and BP, Mobil and Shell came out on top with 98s and 97s, think vortex was around 95

Skylines should only be run on a minimum of 95 RON

I could be wrong, but I believe Mobil actually uses BP Ultimate for its Synergy8000, but makes its own other fuels. This is just a rumour and I have nothing to back it up, except that they are coincidently both excelent fuels.

fuel injectors can be harmed by wrong fuel, I have no proof but there are additives in some fuel that will eat the rubber out on some older cars!!!

Stick with most 98 ron stuff and you will be fine, BP and Caltex for the win

they all do the same thing. only changes when the octane changes. my car runs the same on all the 98 octane fuels. notice a big difference when i use the V-power racing, which is 100+ octane....

Incorrect... Remember that your car still has standard injectors, standard fuel pump and standard computer, when you replace all these for after market / higher flowing items and you have it much more hard tuned than factory you find that the engine becomes very picky about what you put into it.

Mine ran very bad on Shell and almost as bad on Caltex but BP and Mobil are great, so thats enough evidence for me.

i dont think that shell optimax (yes i'm still old school) is too bad.

haha I went to a shell the other week for the first time in ages (cos I had to) & was looking for the blue pumps... couldnt work out WTF was going on :D

but yeah, i always use BP normally :O

    • Is the panel filter one that is oiled? Have you ever cleaned or touched the AFM?
    • So.... the K&N air box thingo was too big, ended up gifting it to a mate, well, by gifting it he actually supplied food and beer at the pub,  which was nice, as it will not sit on a shelf in the garage for the next 10 years I did trim up some of the existing stuff to neaten it all up and gave it some wrinkle paint, unfortunately it currently has a used and abused mish mash of different types of hose clamps, 4 big fat T bolt type (shit), and a few normal clamps of vairing sizes and brands, but..... only until the 6 constant tension black worm clamps that I ordered from EFI solutions turn up next week Currently the current hose clamps are triggering me hard, LOL Is this the final version, probably not, I really want just 2 silicone pieces, a straight bit of silicone from the filter to the MAF is easy and will happen as soon as I head into Just Jap tomorrow, the problematic part is a 30° silicone bend from the MAF to the TB that I can connect the engine breather from the head, I found that there are bulk head fittings for boat bilge pumps that should work, but until I can get a 30° silicone bend the alloy pipe, and the 11ty thousand hose clamps, are there for the foreseeable future 4 hose clamps are golden, 6 are grudgingly acceptable, the 8 currently holding it all together is just taking the piss    I've also ordered 60 more retaining wall blocks for the front yard, I mis-gonculated the height that was required to get above the base of the Photinia's (red robin's) that are the hedge behind the front fence, currently it is 2 blocks high, and about 1/2 a block short, so going 3 blocks high will be above the base of the red robin's, and allow some room for mulch
    • It is the stock air box with the panel filter. Everything else is stock except the exhaust at this point, as I also went back to the cleaned 270cc injectors. I will check the RPM when the IACV is unplugged and report back.
    • As MBS suggested if this is happening when the engine is cold you're going to want to remove the intake air regulator and verify resistance + that the shutter is physically opening and closing. At -20C should be fully open, 20C half open, over 60C fully closed. At 20C should be 70-80 ohms. For AAC valve testing using a Consult cable see if you can raise and lower the idle by commanding more or less AAC duty cycle. Hopefully it's pretty linear as well, shouldn't be like 30% AAC valve is barely idling and 40% is 1500 rpm.
