I have been warned on the latest batch of OPTIMAX. As i am now a temporary australian ( motorbike ) i filled the tank and it fouled the plugs. It took about 1/2 an hour to finally start it. That same night my mate fouled the plugs on his dato 1200 with a FJ turbo. Took him ages as well. The army has a heap of bikes that are out of action dues to the same problem.
Aparently it is due to being re-refined and just shit. So stay away if you can.

No way :-( Which areas are these in??? If OPTIMAX was the cause of all these problems, don't you think that Shell would have disconnected the OPTIMAX pumps by now?
I have a couple of mates that if they use optimax in there dirt bikes & leave it in the tank until the next time they go out (couple weeks) it fouls the plugs & causes it to run like a bag of s*&%. Maybe it would be best to only buy it from a "busy" service station???
I filled up with Optimax a little while ago... not long after my sparkleads died...
Im not sure whether it was because they needed replacing as they did look a bit old...
It is a well known fact among us dirt bike riders that you stay away from Optimax because it leaves deposits and fouls plugs. For that reason I use Techron Gold in my KTM and have no problems. In fact when I bought the bike the dealer expressly told me not to use Optimax in it.
While were on the topic of Optimax, a mate of mine picked up a bad batch when he filled up his Skyline. He put in a complaint Shell ended up paying $1000 in repair bills.
I used optimax in my 347 stroker and I have to say that even with very low kms the chambers etc were very sooted up when the engine came apart. I use Syn8000 in the FPV purely because I like the Mobil pay at the pump. I might switch to Techron Gold for a trial period but I know it works real well in my bike.
Whats the general price difference between the major brands of premium fuel?
