Shell Optimax vs BP Ultimate vs Mobil

[Al]

Ethanol is very bad for the engine, avoid it at all costs!

I am not sure about Ethanol. Some say that it is actually good for the car (small amounts) and some say that you don't need it and can be harmful to engine.

Does BP have ethanol in their petrol? I know Shell advertise that it doesn't contain any ethanol.

Way back before the dawn of time (I.E. Before SAU started and we were all in SDU) someone took the inititive to test all 3 fuels and in terms of the RON ratings they were all pretty close with no major winner between the 3 of them. BP was first, then Mobil 8000 then Optimax. All over the 98 RON mark.

What was more interesting was the chemical content within the fuels. I can't remember what contained what but Optimax had other additives and stuff. I think it was supposed to be a bad thing but don't quote me on that.

I've since tried to find the thread but it's gone to Thread Heaven...

However I feel that you should stick with what you think. All 3 aren't bad and it's not like your going to gain massive HP by running [insert fuel brand here]. People have had different experiences with all fuels some run better on this, others on that.

Ive never had a problem running BP Ultimate. The cleanest fuel too which is a bonus =)

i usually use bp however now with the new 4 cents off per litre im going to give optimax 1 more go, i used to use optimax but then discovered bp and never looked back until now.....1 more chance thats all im going to give optimax.

I use whatever I'm closest to when I need to fill up, but generally have gone for Optimax. Ive found through the 3 main ones that Ultimate seems to give me good fuel economy, where Mobil gives me good performance and Optimax is a combination. Like a good all-rounder... I have noticed that results on Optimax tend to vary from servo to servo sometimes, but if you find a good one stick with it.

In my car Vortex went really well

When mobil first brought out 8000 my line didnt like it

but now she seems to humming with 8000.

Shell works well, havent tried BP yet.

Man BP Ultimate is pretty hard to find in my area!!

Drove into 2 BPs and one had premium unleaded and the other just had unleaded. Look like a fool driving in and driving off haha. I think I found one for sure now with BP Ultimate, but still haven't try it out yet.

well put optimax in today, next week bp going back in. optimax isnt terrible but my car feels more "solid" if this makes sense when its got bp in it.

i tryed bp and vortex and my car didnt like em at all

ive been told by many that these are the best and have highest octane etc

but for sum reason my line didnt take to it very well

ran much better with optimax

:confused:

I manage a caltex servo on the Gold Coast and it has the worst premium grade fuel I have used I never use Caltex Vortex it doesnt have the RON of the other brands... You can tell by the difference in price between the unleaded. Vortex is generally 5 cents dearer than unleaded at Caltex, BP ultimate is generally 8-10 cents dearer !!! I only run ultimate where possible, If I cant I use Optimax.... These two give better mileage which offset the extra cost.. Never really liked Mobile after all the deal with the aviation fuel getting diluted in our petrol so I havnt tried them! The other good thing to do is run Nulon petrol treatment.. by far the best. Its a red container.
