I have a test kit. I know exactly what I get.

For the money, it's hard to beat E85 as a high-octane fuel. And that doesn't even factor in the inherent cooler operating temps and cylinder temps from running it as compared to race fuel. Those 9- and 8-second cars are drivable on the street. Once you get into the 7- and 6-second realm, there is no longer a pretense that the car will be driven on the street. So on a car like that, the compression goes up, the boost goes up, the timing gets aggressive, and you run a dedicated race fuel.

I'm sorry to hear you're disappointed in the mileage, but I think your 13:1 engine is going to have a helluva time trying to run on pump gas even with the computer doing all its cam timing, fuel trim, and spark advance tricks to keep detonation in check.

You get nearly all the benefits for a hell of a lot cheaper. On top of that its more available.
No goes E85 for the mpgs. That's a well known fact. I wanted to protection level it offers. I wouldn't throw your drivo issues at e85 and walk away. You may have issues on a 93/torco blend too. How are you going to consistently get the octane rating your engine needs blending torco and 93? Serious question. Curious as to what your plan is. 10 gallons one can situation? I don't trust that.

Very solid points, fellas.

I tried it so I can hate on it. It didn't work out for me. Hopefully this will. So you can't say I didn't try e85.

I also did the torco thing and hated it. I really don't care what anybody runs in their cars. E85 has worked out well for me and I will staying with it. If all the pieces are in place, setup properly, and tuned properly its the best bang for buck IMO.

My next step will be longtubes and a E85 tune. Then calling out Nick to lose some more races to him. lol.

Correct me if I'm wrong, but the thing about pump gas is that is can vary in octane more than E85 can, and can also have a crap load of trash in it depending on station. E85 tolerances are a lot more strict it seems.

**Bearded Banger** · 07-01-2013, 05:33 PM

Lol, and Kevin wins again.

**BLK2012GT** · 07-01-2013, 05:36 PM

So every car looks like that or that happen to one car and they happen to run torco. If that happens to everyone then wouldn't they be out of business and no performance shop would sell it?

Not really, because it's an after thought for most people. If you run Torco, your motor will look like that in time. It's a by-product of Torco.

Exactly what my plugs looked like when I mixed. Maybe not quite that bad, but pretty much. I had too at the time. No other choice.

Every car will look like that with prolonged use of Torco. This is nothing new. It will turn your plugs, valves, heads and exhaust brown.

Over time, the MMT will build up in the cylinders and could lead to "Hot Spots" if and when Torco is not used.

It won't hurt my feelings if you don't want to run E85. I just want to help you understand there are drawbacks with anything.

**BLK2012GT** · 07-01-2013, 05:47 PM

Right and I appreciate everyone's input. I'm new to the e85 and running torco stuff to. I just want what's best for my engine and won't give me any problems. I tried the e85 and it was a problem. I'm going this route now and if I don't like it for whatever reason then I guess I have no choice then to switch back.

On Torco, I suggest changing your plugs and oil often(more so than usual). Especially after nights at the track where you are spraying it a lot. Torco was all the rage back when the Terminators first came out. I had a couple of Terminator friends who will go unnamed (haha!) that used Torco so much that one blew a couple of motors and another one who had a plug seize up in the head due to it being so corroded from not changing them often enough on Torco.

Exactly.

You gotta change the oil a lot on E85 too, due to significant water absorption. I wouldn't go much further than 2k miles myself, but I'm sure the E85 pros will chime in on their thoughts as well.

This is a crankcase catch can after 100 miles of running E85 on a boosted Evo:

**46Tbird** · 07-01-2013, 06:36 PM

Every fuel option has upsides and downsides. E85 is an awesome alternative for cars that need a high octane rating and some street use. It has some maintenance issues and it's hard on fuel systems, although the '11+ Mustangs don't seem to have an issue with it.

I never like mixing fuels, not because it's going to mess up some secret 'formula' for maximum performance, but because it's just a pain in the fucking ass. Driving to the gas station, putting some 93 in the car, then going back home and putting the right amount of 110 in it... think I'll pass.
