BP Ultima vs Shell Optimax

Not sure if in right section but but....

anyone tried the need BP Ultima, i've been told its 101ron but i thought it was 97ron just light super unleaded, i know shell optimax is either 98/99ron, i normally run on shell optimax but filled up with bp stuff this morning

 

Keep us posted on how it compares

 

I ran my '89 Valver on it last week... seemed to run ok... but did pink a bit under load. Never get that with optimax.....

The jury is still out at the moment.....

 

Problem is you need to pass a couple of tanks worth of BP stuff if you have been running optimax through the car before you get anywhere really on the comparison side of things.....

 

Bp Ultimate is 98 RON

 

The BP Ultimate we get in the UK is still only 97 RON (see here). Early indications from the Scooby boards are that it does not show the same performance benefits as Optimax.

i still think the optimax is superior.

don't think you can get bp ultimate near here will (oakgreen88).

 

also worth noting that RON values decrease if the fuel's been sittin there under the fourcourt for a while, so its best to go to a busy petrol station (as they replenish their stocks more often).

 

ooops.Bp Australia has 98 RON.In the UK it is a minimum 97 RON

 

The RON doesn't decrease if its been in the forecourt for a while.BPs words, not mine. No prizes for guessing where I work

 

So do most people see a noticeable advantage when using optimax over regular unleaded? Never been sure how much difference it makes to my mk2 16v.... always wonder if it is just "placebo" effect.

 

I definately see a difference..... My MFA indicates a drop in average MPG of about 10 MPG if I use normal unleaded.

The car runs like a bag of sh*te too......

It's an '89 Mk2 Valver with 185k on the clock!

RON does decrease if it has been in the forecourt for a while, it is around 1 ron or so pr year, so nothing to think about when filling up

 

acf8181, BP ultima is sold just where i work - bracknell
97 ron? think i'll stick with the optimax then

 

Right, back to opti then

 

your car will be faster, because its now much lighter cos of the amount you just spent on filling up on that damn stuff!!

 

I noticed a very slight difference in throttle response on optimax and no MPG difference whatsoever.

 

Iv never used optimax or new bp stuff, jsut good ole UL but i did notice a slight performance increase if you use 10 UL and 5 Leaded.

 

oakgreen88, I may be offered a job in Bracknell, working for cable and wireless, whats it like to live there mate? Any good?

 

Bracknell isnt so bad, i only work there tho, live in maidenhead which is close by, thats better! quite a few meets round this area aswell which is good,
