Alrighty...... Im not sure bout this optimax? stuff honestly cant say ive seen it here in WA mind you havent looked for it, But is there anyone using BP's new product "ULTIMATE.98" i found after adv the timing she really gets up & BARKS!!
Highway driving im getting 480k's to a tank but sity driving,*mind u lead foot here* a poor 330-350k's
Well following the run to Bathurst on Sunday I can safely say Optimax has the better fuel economy over Synergy 8000. Both XLR8 and I filled up with Synergy 8000 in Newcastle for the trip down. I have an ED 6 (Modified Engine) and XLR8 has a AU XR8 we had both used half a tank of fuel not long after leaving Penrith for the trip up the mountains. (Mind you we were not taking it easy). We filled up with Optimax and proceeded on the trip raced around Bathurst and ticked up around 300 km's before needing to put 28 litres in the tank... And it was no "Sunday Drive"...
I filled up with BP Ultimate when I was down in Canberra for the GMC400... I got 511km with 60.48L (11.83L/100km)
I filled up with Mobil Synergy 8000 just before going to Bathurst on Sunday and ended up getting 499km with 62.84L (12.59L/100km)
(although I must admit - I was driving a little harder on sunday and ended up getting stuck in traffic doing 10km/h on the way home)
I dont use Optimax anymore as my car pings its nuts off when I use it, and I also get a 6kw at the rear wheels decrease when running optimax (130kw with Synergy, 124kw with Optimax - proven at the dyno day)
Oh Great Kelli,
Now im confused to what I'd like to get my car tuned for. optimax or Syngery8000???
hmm will have to wait and see. I guess I'd have to get the car dynoed for both fuels and then decided on which is better
I have only ever used optimax but after reading kelli's stuff from the dyno day I tried the synergy. I travel up & down bulli pass every day& have never had a problem with the optimax but with the synergy the car pings its guts out over 4000rpm
Well i have to say. Due to having to drive to canberra every fortnight. I usually lash out and fill with optimax. On an average run to canberra with little hick-ups with the traffic, i can average about 230k's to a 1/4 of a tank and some times better ( 260 tops).
And for the fun stuff on a cold night out at Wetherill Park in the early hours with most of sydneys rev head population. A stock EFXR8 manual, runs a nice 1/4 with optimax and a bottle or two of nulon octane booster. I had fun with a holden out there one night. By the end of the night i no longer had a set of pirelli p6000 on the back.
So i highly recomend the optimax.
3 thumbs up shell......
Blue EFXR8 with grey strips. Everyone out on the bathurst run should know the car by now!!
Your engine shouldn't ping regardless of what fuel you put in it. Even if you filled it up with normal unleaded, the knock sensor should (if it's working) tell the computer to retard the timing to the point where it doesn't ping anymore. My TE-50 will only give a single ping on an upchange when hammering hard uphill, (on synergy). How many K's has yours done?
