Just need an opinion on V-Power Racing, there 100 octain fule.

Also found that United petrol stations have 100 octain fule.

Is V-power Racing recomended over BP 98?

[gareth_oau]

has anyone tried an after-market octane booster?

just curious if they do actually boost octane (if yr already running a 98 or 100), and also if the gains are noticeable and cost effective.

(by the way, Toluene is a great octane booster, but just close yr eyes and ears if they happen to mention the carcinogenic properties.... ) (oh yeah, it also destroys rubber fuel lines)

I have a Polo GTI. I had a novated lease and Caltex 98 was included.

Occasionally I would do Shell V Power Racing and pay for it myself. Shell Racing was MUCH better than Caltex 98 in terms of power (but poor fuel economy, even going easy). No longer tied to Caltex so have been using BP Ultimate 98.

BP is great - much better than Caltex and can't distinguish between Shell Racing and BP 98.

Picked up my nice new shiny Tiguan 147TSI on Friday...
so been re-reading lots of these threads...

To summarise it sounds like
1. BP Ultimate/98
2. Mobile 8000

Will start with BP98 and see how I go - thanks for all the information and observations all!

Yeah, cheers guys. Had my Polo GTI for almost month & it's had BP Ultimate in it since I drove it out the dealers. Might trial Mobile 8000 for the next few tanks & see how I go.

I've been using BP Ult since I bought my Jetta, and have always been happy with it. On occasion though I did have to use Shell Prem and I did notice a difference, negative in a way. I think the car gets used to running the same fuel for a while and when you change you do notice the difference. After reading some of the posts here, I will give Mobil 8 a try and see how I go.

ive gotta agree with you guys, bp ultimate seems to run best in my pog. never had any issues and it makes her run very very smooth.

[goodfella]

Heres an interesting observation I made...

I previously ran Shell VPower continuously then changed to BP Ultimate for a few months straight, found BP more responsive...

BUT...

after I got my Custom Code ECU flash, I ran BP for about 1 month and then changed to Shell for a month comparison, as soon as I changed back to BP I noticed a definite loss of responsiveness....so went back to Shell again.

Interesting how the ECU mapping was so sensitive to the fuel I used.

So I've been only using BP98 since getting my Tiguan, but the only BP in the inner north of Canberra looks like it has closed for major renovations (if even if they are coming back?!?!)

Today I had to put Caltex 98 in it (which from reading this thread wasn't most people's preferred option...

so now I guess I need to find a Mobil?!?!

We have lots of Caltex's stations inner north Canberra...
a couple of Shell, and not even sure if we have any Mobil stations anymore?!?!

[gareth_oau]

DJY, as a rule of thumb, i'd suggest that you use whoever has the refinery in your area. the closest refineries to Canberra are Shell and Caltex both in Sydney.

If you buy Mobil, BP theres a damn good chance that fuel was made by Shell or Caltex and is just rebadged as BP/Mobil
