I've had some other people mention Optimax as well when I suggested I'll try running the car on something other than straight LRP to try it out. Is Optimax significantly different in any way to the other 'labelled' types of premium ULP? I would rather not take the head apart on the engine to determine the type and condition of the valve seats, etc. while I'm lacking some important tools (mainly a proper torque wrench, etc.), so I might try first of all running with a mixture of half-LRP and half-Optimax or another type of premium ULP and see how it goes. Since the car is from the pre-ECU era I don't know what different it'll make not having an ECU to manipulate engine management settings when running on alternate fuel, so I'll see what happens. 8-) Pricing for LRP and premimum unleaded fuels is around the same at most places in the part of Sydney where I live. Since fuel pricing for ULP hovers between the low 80 cent per litre mark (that's A$0.80) at the start of the week, rising up to almost 1 dollar per litre by the end of the week, it's impossible to get better pricing without driving a long way to cheaper fuel suppliers, and/or always making sure I fill the tank on low-priced days (Monday to Wednesday normally).
