Re: 100:1 Mix
I just bought 2, 3.2 oz packets of Opti 2 off of ebay for $10. Not exactly a bargain packaged small like that, ($200 a gallon) I'll give it a go though. At 100:1 that's only 1.28 ounces to a gallon of gas, so those 2 packets are enough for 5 gallons. Since my build isn't complete yet, I'll go with 85:1 for a gallon of break in.
If someone thinks the break in ratio should be different let me know. I'm sure it's covered in the posts, but there's so many of them to look through.
