Ok! Yesterday evenin, 6-11-19 (I didn’t have much time before dark), but I cut up 4 or 5 tree trunks, 8’-15’ long, 10”-18” in diameter, at around 16” sections! Using my mm’ed, fully adjustable carb, ms170 w/14” 3/8 .050 chain!
I don’t remember how many, but 4-6 tanks of fuel and bar lubricant refills! I went back and forth between TSC bar oil and Walmart Canola oil!
I took my Harbor Freight laser infrared thermometer gun and measured the temps of my bar and chain and muffler after each trunk and after most individual cuts!
The max rpm’s was under 11,000 I believe!
The temps, ranged the same for both lubricants!
(The canola oil possibly was a bit cooler?)
I’m thinkin the bar temp with both lubricants ran from between 130°-160°
A cpl of the trunks had some hollow areas with some wet dody wood, so, I’m going to keep experimenting when I have all solid wood!
It was encouraging/interesting to see that the temps were at least close between the two lubricants!
I wasn’t able to test it with my ms250’s!
NOW, ...even if it proves that the temps run the same between the two...does that mean the “lubricity” and wear and tear are the same??
Will they differ between the two at higher rpm’s on bigger saws??
Further testing and research to ensue!
I would be interested in what others find, with actual temperature readings, instead of just “opinions” based on “what’s been excepted as the norm”! (Even though, those are welcome as well!)
