At first I used a volume mix of 128:1 gas to oil and
soon noticed an
increase of engine lubricating oil volume in the oil pan
I have gradually reduced the volume mix of gas to oil to 140:1 but there
is still a slight increase of engine lubricating oil in the pan.
Also a local mechanic has mentionned that the two stroke injection oil
is degrading the 20W-50 engine oil.
How much can I reduce the volume mix of gas to oil ?
Please advise

Yes
you will get an oil accumulation and there is no getting around it, I would mix
at no less than 100 to 1 ratio, I have seen no problems with the 2-stroke oil
mixing in the case oil and only change my oil about every 200 hrs.
I started mixing 1 oz/gal (1:128) in my
20B. In about 15 hours (90 – 100 gals of fuel) a gained about 1.5 qts
of 2-stroke oil in the pan oil. That would be about 13 qts in 200 hrs J.
Based on discussion here, I reduced the
pre-mix to .75 oz/gal (1:170). I still find some dilution of pan oil; so
I change every 25 hours. Kind of a spendy waste of 15/50 synthetic, but I
don’t think the dilution is a good thing for the gears; and I don’t
intend to reduce the pre-mix any further.
