Will injectors gum up on ARCO gas?

Yeah I do. But when I was E40 tuned, I went up in weight with Torco Oils. 14 bucks a quart.

Oh crap! That's expensive!! I thought Amsoil was expensive at $8 a quart

Although what everybody is saying about Ethanol is true, when ethanol gets old and sits in a tank too long it turns solid. Like a clear goo.

I thought it collects water when it sits to long

Just to comment on the "ethanol cleans injectors" idea...

It absolutely killed older revision injections on 300zxs. The Pintle-based design in that car has a constant 12v on them, and I assume it was galvanic corrosion that did them in as the E10 pulled in moisture. There was a new revision on the injectors and I ended up dumping all my stock 370cc for 740cc injectors on the newer design way back when.

Our manuals spec that we're good for E15... but (shrug) perhaps our injectors are a little susceptible to failure. Even E10 killed stock Z32 injectors pretty quickly when it became widespread at the pumps and was a known issue. Now? I bet most the remaining cars are on new-style injectors as the old ones have long since failed.
