Can't give a value judgement at the  moment as my Omega isn't working too well.

Nice to see you posting again J 8-)

What's the problem, Zulu? Can't see any posts about it in the Help section!
 :-?

I haven't posted anything yet Nick.  The car isn't used very much - about 1000 miles from the same time last year - and about 1 month since it was last driven.

The battery runs down, the engine doesn't fire up immediately, the management light comes on - and on this occasion has remained so - although the car seems to be driving ok.

Sounds like you have very minor problems.

As I've mentioned before, I use V.Power all the time now, I used it in the MR2, and when I got the Omega I used standard petrol for the first couple of weeks, then switched to V.Power, I noticed the difference, smoother, and more power. Don't know about economy though, I've not checked that, but V.Power is a cleaner fuel as has been mentioned, so, whatever is best for the engine is what goes in.

I've not noticed much difference between supermarket or BP / Shell in my V6. It tends to average 30-31mpg on my usual commute with whatever I put in.

i did a test not so long back i reset the trip computer to zero  put 20 quid in of normal petrol from tesco set cruise to 60  went as far as i could round york ring road till it had o miles left  then tried that 99 octain stuff from the same tesco did same again to see if there was any difference bit more power but not a lot did the same with total bp shell and jet . Total and jet came out the same as they use the same petrol and diesal  jets super unleaded  is totals exciliam as i was told by the jet garage bp was a lot better bp ultimate was even better i found the standerd shell was about the same as jet and bp standerd petrol but the v power did give lot more power but less mpg (but lots of fun when i put it my suzuki 600 bandit front wheel dont wanna stay down)   the bp ultimate came out on top more mpg and litte more power but not as much as v power hope this helps

Even im not mad enough to do that!

That's some dedication to the cause

I have noticed a small performane and mpg gain from my mig with optimax.When I put it in my 650 Bandit it also saved on front tyre wear as it was more skyward than usual.

A high compression or turbocharged engine will almost certainly need high octane fuel to avoid going into knock retard and reducing power.

I always used to think that until I saw the SuperKaos Hayabusa Turbo......18lbs of boost on standard petrol without a problem....and yes, that speedo is calibrated in MPH

I want one for my Westfield.

How they survive that sort of tuning beats me. Not being opened up for more than a few seconds at a time perhaps?  :-/

Them Busa lumps have more respected predigree than most realise Kev.

A "mild" tune is 350 or so BHP, a "mid" tune yields 500 BHP, and they can easily (and reliably if you do the job properly) make 700 BHP.

[albitz]

Yep,they are unburstable those engines.Performance Bike mag.Built a 700 bhp version a few years ago.Those japs are very clever engineers.
A mate of mine had an early Busa,took it to mainland europe and held it flat out for over 5 miles,it was reading 220 on the speedo.

Suzuki have been building bullet proof performance engines since the 80s the last troublesome TSCC engine was the 250/400 twins with head cracks, after this - bullet proof
