neither - BP ultimate.

If i had to choose though, it'd be Synergy8000 over Optimax.

The only petrol which doesnt make my car's check engine light come on in 4th gear under high load is BP Ultimate, granted the PowerFC was tuned with Ultimate, when Optimax is in the check engine starts to flash in high 3rd, low 4th. Synergy has slightly more tolerance over Optimax...

Running the car recently with a gas analyser attached produced a surprising result. Optimax has changed chemical composition replacing vital Carbo's with crap, I think the best one to use at the moment is Moble's new 98'. It was allot better than the optimax and had no nasty "solvents"...

    • Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
    • Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
    • Hi All, putting the engine back together and everything is perfect except have this plug left over.. any ideas what it is for and where it goes? Is on cold side under the intake plenum *note not a stock plug, as everything has been modified Cheers
    • Sounds like a misfire. Check fuel pressure and don't even think about going into boost while it's like this unless you enjoy engine rebuilds.
