So this is my first post in this forum. If I am posting at the wrong place, pls tell me :D
Many drivers disagree with the idea of using a different fuel brand on their Suzuki cars(and other cars :D). Tried to edit in a link so it’s a banning for you. The short answer true. Any commercial fuel sold at the pumps should be safe enough to be used on your vehicle, provided that it follows the standards recommended as set out in the owner's manual. Switching fuel brands is a normal course of action, affected at any given time by reasons such as price and availability of branches.
If you move to another brand, will fuel consumption and efficiency be affected? Most certainly, for better or worse. For one thing, the Big Three fuel brands are likely to use a more complex formulation in their products compared to smaller oil players, such as having more detergent additives to avoid the build-up of carbon deposits.
In any case, if your car is equipped with an engine control unit (ECU), it will be able to change engine output after a certain number of kilometers based on the type of the new fuel.
If you find yourself running low on fuel and there's no branch of your favorite brand insight, it's okay to replace another brand in the meantime, just to avoid stalling in the midst of nowhere.
Even if there's still half a fuel tank left and you want to try another brand of gasoline or diesel, there's no problem. The only negative impact is that mixing two separate brands would keep you from taking full advantage of either fuel.
If you have any other concerns about car fuel, comment below. I'll answer all if I can :beer:

Can you provide some background for this information such as your field of interest/expertise/employment?

For the record I subcontract to an oil company and work at an oil refinery producing fuel for the Australian market. Fuel is generally sold on the wholesale market and at most the POS vendor adds their own additive pack which is mostly dye and detergents.

Whilst there are different catalytic processes used to “crack” long HC molecules to shorter molecules, the end product is cat naphtha that’s then blended to ULP, then subsequently blended further to the desired octane.

What is the “more complex formulation” you refer to? Are you referring to the additive pack?

I've been a support provider for two of the three retail fuel distribution channels here, and this is how I know it's handled - all the fuel comes from a single source, and the chain adds the additive pack just before the road tank wagon rolls out to make the delivery.

I would not hesitate to use fuel from either of the two chains I've worked with, but I will not buy fuel from the third unless I absolutely have to, and that hasn't happened yet.

Yes Fordem, that’s my experience at the tanker loading terminals here. There isn’t a tap in the refinery marked “91 octane” and another one marked “98”- cat naphtha is blended to the finished standard required and then “branded” by colour basically by the vendor.

What I’m interested in is that the OP either has very little or alternatively a very detailed understanding of the chemistry of refining. (I certainly don’t have a detailed understanding of the chemistry, just the process) I’m aware that when fuel is subject to spectrograph it is easy to identify different fuels from different refineries, but I’m in no position to determine if one refinery produces fuels that are “more complex” and I’m at a loss to understand how your car would know how complex the fuel is- the only really relevant measure is octane.

Additionally, and this is where I find the logic a bit of a struggle, is if these “more complex” refined compounds are beneficial, how is that relevant at a lower octane? I can’t run my car on 91 when it requires 98 regardless of how “complex” the compounds are in the fuel. How would 91 octane produced at the Viva refinery in Geelong, Victoria be better or worse for my car than 91 Octane from Mobil Altona 40km away?

Personally, I think the OP is basically just talking about octane, and their post would have made far more sense if octane was mentioned. Writing things like “most certainly” efficiency and performance will be different between brands of fuel is a fallacy.

Chances are it’s a spammer, I just let this one through because it didn’t have any links in the post and I wanted to see what happens


On topic, I just chuck whatever is available in my car. Opal, 91,95,98, LL avgas. I don’t care as long as it burns and I don’t have to walk

Yeah I agree there’s something fishy about the post.

That's been a challenge for me also - and yes, sometimes the only way is to let them through & then observe.

The sneaky bugger tried to edit in links so it’s a banning for him

Maybe delete the thread? Not much value in it.

I'm stoked that you've been able to move past velcro.

Did you tie them by yourself like a big boy?
