I always use that stuff and I let it run long enough to get into the carb/EFI manifold/injectors ETC.
This ethanol seems to be a big issue for "un-sealed" systems. I also put crap in my backhoe for the diesel anti-gel which seems to work well.
Although a year passed, It can't hurt..... Right now my truck is off the road but I start it, warm it up and take a few laps on the track every once in awhile. Biggest thing with auto's (I find) is that the rotors rust and immediately ruin the pads. Plus with 9.99,19.99 and 49.99$ rotors out there, I imagine it's all different steel. I rarely get the "lifetime warranty" stuff because I know it's crap and they just hope you lose the receipt. I bet 75% of the people who buy those parts lose that receipt.............
With our trikes, if you don't ride them, just be prepared to take the carb apart and all the jets out and clean it all when you ready to enjoy it again
All our government does is distract us while they steal from us, misspend our tax $ and ruin our country
