Gday guys just want to start a little bit of a open discussion here, we all know that usually the more octane you run(obviously to a certain limit) the better it is for your car when your dragging/track etc but since you all know the petrol prices have sky rocketed, $1.41 at mobil just before for synergy so i just want to see what people think/experienced when running normal octane petrol not 98 RON? i have been running mobils synergy since i got my car like 2 years ago and it has never noticably misfired or had a problem due to a bad batch of petrol, but since im still at uni and earning jack shit a week was wondering what other people run? I dont go to the track and dont regularly drag so would it be worthwhile staying with 98RON?

with the stock ecu if you put in crap fuel and nail it, it will pick up detonation and switch to the low octaine ING timing map and back off timing everywhere. it will certianly work, just feel a bit sucky and flatish.

users with aftermarket ecu's can achieve the same goal by basically taking say 5 degrees timing out the of IGN map and it should run medicoreish on crap fuel

I'd rather put my sneakers on than resorting to not putting 98 RON petrol in my vehicle! Thats the last place to cut corners on a budget I say..

Edit - BTW I believe with the ignition retard, your fuel economy will suffer so you wont save much $$ at the end of the day. Maybe enough to pay for a cup of coffee and thats it.

    • Fuel tank is out. Looks pretty bloody good under (ie above) the fuel tank.  Amazing how good the factory e-coat holds up in the hidden areas.  No where near as much body deadener to get rid of as the front but still not looking forward to it!  Shit of a job.  I'm thinking I might grab a needle scaler and give that a go before I attack it with the angle grinder and wire wheel which is how I did the front 2/3's of the car.  Feels good to be working on the car again but who knows how long it will last!  Hopefully I can get it further forward than where it was prior to this last block of work when I decided to go back 10 steps further down the rabbit hole from where i already was! The problem is, I'm realising how hard it will be to repair and paint the bumpers, which cannot be put back on the car, and have a good paint match. There are also areas where it would be VERY hard to hide the new paint where it transitions from old paint. Like this- There is only one way to do that perfectly and I really dont want to have to do what that means I would have to do... 🤦‍♂️
    • Pretty sure the factory assembly doesn't have any gasket at all, just RTV.
    • I will get a couple cans for sure thanks, I do have 2lt fish oil to spray around the car already.
    • Thought I’d post pics of the packages for those interested. The premium package is #16. Remote start, security with tilt sensor and remote and backup battery, auto fold mirrors and door illumination.    Can post up pics of all the factory options and images from the factory options brochure if people are interested. I have all the dealer books etc for all rv37 models. 
    • After its dried out Penetrol is you friend to treat rust and seal up those seams
