Along the same lines, I do believe PEA like si-1 from all of the info gathered the last decade here, you want the opposite. Since you dilute PEA heavily with gas, clearly the more concentrated you can run your PEA, the better the outcome. With the latest test you see "some" cleaning with techron, well my thought or theory is you can replace si-1 with other PEA products so long as you super concentrate it. Instead of running 6 bottles of techron over time, run 6 bottles at once, or something like that, you get the idea. Same thing with si-1, I now know with current info I would never run less then a full bottle with a tank of gas. I would rather run it super concentrated once at the end of the oil change interval, then any other strategy. If I ever get a chance, like a buddy comes over and we boro his chamber, if it is bad shape, run 2 si'1's and see how much more effective it is like this. Because of the oil content of si-1, I wouldnt run multiple bottles, the most I'd attempt is two versus 24 gallons fresh gas.
