What Petrol To Run?

[Bazza96]

Hey guys, sorry I keep making new threads.. Just so much to learn and ask!

Next week, I am getting a custom tune at Forced Performance and Tuning in Toowoomba.

Now I used to fill up at the BP down the road, and I ran 98 octane 99% of the time..

I have recently moved, and my closet petrol station is a united.

They only have ULP91, ULP95 with 10% Ethanol, and 100 Octane fuel.

Im not sure what I should run through it, should I keep visiting the BP and putting 98 in her?

Or is the 100 Octane fine at United..

Ive always seen BP to just have better quality fuel, and always know its good there.

But this 100 octane stuff, could it be just as good?

And before I get my tune, heard a couple of rumours that if I change my oil to 5w/30 Syn Castrol edge oil..

That it will give me a little gain(5rwhp), and is 100% better for my car?

Just want to make sure my car is ready for the tune, and not going to have to pay another $900 Dollars for a tune.

Kind regards.

Bailey.

I've been using united 100 octane for 2 months now, nothing wrong with it.

will use a little more 100 to do the same distance as 98, but the main point is once tuned, you need to use the same fuel

Use the factory recommended oil grade, pick a brand you like, change oil regularly- and that means a bit earlier than the factory service intervals (p1ss easy job) and use proprietary brand filters. If you tune for 100 octane you will need to always use that. IMO, use 98.

5 horsepower on 5w/30 - as compared to what grade of "other oil"? IF it was true you would not even feel that sort of gain on the road.

Do the tune and then sit down and decide where you want to go with this car. As we all know, chasing power is costly and a 4 litre N/A can only go so far. Remember that the turbo version of the FG is a real goer ......... so maybe enjoy the N/A for a while and save the bux to buy the Turbo. Sadly, once you drive the T......... you just have to have one of them.

United 100 is awesome fuel and better than 98 for power.

Okay, ive just found out.. that 100 octane is actually 10% ethanol.

So where does that leave me now? 98.

98, it's readily available.. Most 98's are comparable (lets not talk 7/11) so you don't always have to go to BP..

which is why it will use a little more to do the same work

[Bazza96]

Yeah, just gonna get it tuned on 98 octane.

In toowoomba, there is alot of crappy survo's.. like they are a locally owned place.. and weather they have 98 or not..

Not going there, ill stay with caltex and BP.

Where the hell are you getting fuel?

Toowoomba has some of the best servo's I've ever been too..
