OPTIMAX - Why ?

[John Mac]

Several threads I have followed seem to plug for using Optimax fuel - why is this ?
For me to use it means a 20 mile round trip - is it worth it?
At present I'm running on Unleaded 95 Ron and it seems OK.
Thanks in advance

An interesting few comments - If according to the "Bible" the 2.9 engine can run on leaded or unleaded petrol then presumably the EMU takes care of the tricky bits in sorting out ignition etc. Earlier threads have talked about ignition timings of 8 and 12 degree BTDC, the "Bible" says 12 for both fuels, does it therefore REALLY matter what fuel is used for everyday running, I acknowledge that some fuels claim to burn cleaner but does it really and do we keep our cars long enough to worry?
The EMU must be clever enough to read mixed fuels because I've filled with both fuels and I'm still running OK. Perhaps I will run low in the tank and take the 20 mile trip and fill with OPTIMAX to see if I notice any improvement.
Don't agree with Johno's comment on Tesco and Sainsbury, they don't make the fuel they only sell it. There are only a small number of petrol refiners and it all starts out from the same place (generally speaking) I've toured all over Europe and bought petrol that you have never heard of and the car (cars) have all performed without any noticable difference. I'm quite happy with Tesco and Sainsbury - anyway Sainsbury is BP petrol !!!

Certainly where I live Sainsburys are BP- their new NECTAR card shows BP as well and the forecourt logo is BP.
Safeway is also BP, logo, pumps etc all showing BP signs.
All pumps have to by law show the correct RON number they dispense, I dont think you will ever go to a garage forecourt and not see this.
Perhaps in the middle of Dartmoor you may still find a hand operated pump not displaying anything, find one and I will eat my petrol coupons !!!

I can remember my old Dad telling me whenever you want to sell your car always clean it and put in 5 Star as it will go better.
Mind you - he also told me when braking lights came in to disconnect them as it would save wearing down the battery !!! he was a good Scotsman !!
