SHELL optimax VS BP ultimate FUEL ! For DOHC VTEC

[Hans Bond]

i dont think the v-power and vortex 98 are comparable as it is pretty obvious the vortex is better fuel. I think u gotta compare the v-power racing and vortex 98 to get the best result

V-power racing is not the best. I prefer V-power over V-power racing.

V Power and all other 98 octane fuels have additives which clean ur injectors and engine internals.

so theres no need for me to fill injector cleaning fluid if im using V power but if im using BP Ultimate, i should ?
Does using the fluid make any difference to km's. Also, how often do you guys do it ?

[ON VTEC]

v-power racing is just the same as the v-power 98, performance wise anyway
to me it just seems like that the v-power racing just last that little bit longer than the v-power 98, but that little bit longer of fuel is not worth it in a way

but with the BP ultimate and the BP 95, i nearly got the same km's with both it veries really, all cars have there good and bad days, and the weather (hot cold) high way or city driving,

but to my car BP98 just feels that little bit betta then all the rest

If you are using V-Power or any other 98 octane fuel then there is not really a need for the extra fluids. In asnwer to your question BP Ultimate is a 98 octane fuel. IF your vehicle is misfiring, a bit jerky or underperforming an injector cleaner MAY help but it could be a number of other things also contributing (eg: fuel filter/pump/lines, spark plugs/leads and ignition timing just to name a few). If you are using 98 octane fuel then adding in extra injector cleaner is not needed. It will not increase ur mileage if you use 98 octane fuel.

If you use it with 92 octane or 95 it may increase mileage IF your injectors are not very clean.

I would recommend using it with 92-95 octane fuel every few thousand kays however you dont really need to because all you need to do is fill up with 98 instead every once and a while (cheaper).

Hope you can make sense of this im not sure if it makes sense lol...

Ultimate also has cleaners in it.

As didz mentioned, most fuels are designed to keep all the internals clean to ensure maximum efficiency. I can relate to a previous experience while using Vortex with my dad's car.

At that time he just got himself a 2nd hand car and according to the previous owner he only pumped regular unleaded(did not specify which). As my dad works for Caltex, naturally he would pump only the best from Caltex.

Several tanks later with Vortex, he noticed the car started to have problems and it was very sluggish. The car just broke down one day and could not be started. When the mechanic got back to us we were told that the whole exhaust system was totally clogged up. Apparently Vortex had cleaned up the engine so much that in the process it clogged up the exhaust and caused those problems. Btw, this was back 7-8 years or so so I may have missed out on some details.

Also if I may add, in the context of current fuel available for the general market, different fuel does not add power to your car. It is the cleaning properties and efficiency of the fuel which keeps your engine clean hence allowing your car to perform at its peak output and mileage. As previously mentioned, some fuels work better on certain engines, you just have to figure out which works best for you

[De_Cruelz]

If I may add again, and also relating to didz's post - cleaning fluids, additives, etc are not necessary. They are expensive and not worth the money in my opinion. The simplest and best way is simply to use a petrol of your choice with some cleaning properties e.g. Vortex, Ultimate, etc. I'm not really familiar with other fuel but you get my point.

I'm not sure about the market in Australia but back in Malaysia where my dad works, none of the Caltex petrol stations sell additives, injector cleaners or any sort of those cleaning stuff you add to your tank after a refill. The reason for that is simple - these large oil companies spend billions in R&D to make the best fuel. Why would you have to spend extra cash on additives, cleaners, etc on such a product unless you're using an inferior product?

Well, I just pumped a tankful of Vortex 98. Let's see how this goes.

[EL_DC5]

I honestly have tried All the fuels and the only main differances i have found from personal experiance is that :
BP Ultimate: More power better responce
Shell V-Power: More Km's per tank

Speed safe

Is it just me or is all the fuel the same?
Cuz last time I checked its just general pump fuel not rocket fuel for a high powered jet engine....

91 and 95 octane are usually the same across brands (same supplier). But the 98 octanes are made according to the brand's specifications.
