It is indeed one possible formula for a 2-cycle or a "pass-through lubrication" system.
There were four correct answers with Mr. W. Wilson giving the first correct answer, so he can present himself with the BITOG virtual Coffee Mug with Gold Leaf Lettering.
I typo-ed the percentage of polyisobutylene thickener which should have been 40%, otherwise, that would give a formula having 109% of ingredients.
But what is a few percentages among friends???
This a clean burning, very low deposit formula because it has only one metallic component and that is the MMT, which is both a combustion enhancer and raises the octane rating of the final mixture.
This formula is good for 50:1 to 100:1 fuel to additive ratios.
To Show variations in formulae, here is another excellent preforming but expensive mix:
(4.5%) - polyisobutenyl succinimide dispersant
DSP 220
(6.5%) - Oronite
Oloa 9362
(32%) - PAO 22
CP
(27%) = PAO 7
CP
(2.4%) - n-Butyl Acetate
(28%) - Polyol Ester 12 cSt
As a second question, would any qualified responder care to guess as to the reason for the n-Butyl Acetate?
Both examples of pass through or 2 cycle lubricants seem well suited for the task. The one with MMT would be fantastic in my hot chainsaws.
