Premium 100 octane from united, is any one using it in there escort, if so what do you think.

Isn't it an ethanol blend????  Dont know anybody using it

It's ethanol blend and its was crap in our speedway v6 engine kept blowing head gaskets went back to ultimate no problems

Why would 10% ethanol be responsible for blowing a head gasket??

Cause the fuel octain wasn't 100 like quoted and signs on pistons showing det. That be why in my case.

I have read many stories of petrol station ethanol blends not having the quoted octane rating.  There are Australian rules relating to what they can and cannot do but I cannot recall them.

Are you aware the two fuels have different specific gravities/densities? In other words did you check AF ratios with a lambda on a dyno first? The simply using united on a car tuned for bp98 will run leaner perhaps causing detonation. It's not just a matter of higher octane and wind up the timing? I ask because I've also been interested in running this fuel but fuels are often misunderstood or misused giving them a bad rep.

I have been using United 100 for about 4 years in my MK1 1600 (built to formula ford specs) and have not had the slightest bit of trouble. First tried it when I could not stop pre ignition even with BP Ultimate. Car runs nice, starts easy, does every thing right. Went back to BP, and other fuels when on trips and I can notice the difference and the pinging. Would recommend it to any one.

I going to start using JPF100 in my rally car.  More consistent blend than United but same thing.
