prasac - great post mate. I too have had good results with no notable detrimental effect on parts, or the way it runs. I've been running my car on it for 18months now. I think it could be longer iirc. But the bottom line is, it has worked awesomely for me and I save about $10-15 a tank when I fill up.

I use Caltex E-flex at my local in Woodcroft in SA. Some of you already know I run a s/c with low boost (7lbs) on a stock 6 engine, I run a Walbro 255lt/hr fuel pump and 36lb injectors and run a blend of about 40% Eflex and 60% 98 from the same place. The 98 at Caltex has 10% Ethanol added to their fuel so it makes no difference to me. Found I felt the car gain more torque from the E-flex compared to the straight E85 from United. This is a seat of the pants feeling so I have no figures backing it up. But I also went Eflex due to it being so close to home rather than trekking 20km out of my way to fill up.

Again, no issues to date. I have recently swapped my fuel filter over 'just in case' and found in the old filter, it looked dead clean. No sign of muck, gunk or grit to be found from the old filter. I was surprised.

I understand some are apprehensive about running E85 but I have found pretty good benefits not just in power but it works out a bit cheaper for me at the pump too.

I must stress though, anyone who is considering it, a tune is a MUST. DO NOT attempt to put E85 in your tank without first consulting your tuner and getting the right hardware fitted to your car as well as a custom tune to run the car.

otherwise I recommend it for all boosted and moderately modified cars as either an occasional option or as an everyday option like I am.
