Thanks for the testing videos. Now that you have a newly scored piston, do you think it would be possible to run the Opti 2 oil at 40 or 45 to one to see how it compares to the other oils?
@richardflagg3084

Nope. Don't take that the wrong way, but it didn't burn that clean at 100:1 and that's a deal breaker for me. Opti2 actually recommends not mixing mixing it at 50:1 or 32:1. There's a picture on their website that has a 🚫over a couple of gas cans with those ratios. There's a lot of oils I have tested that outperform Opti2 and there are folks in the oil industry that have chimed in that agree.

Been using Saber for over a decade in all my two stroke equipment. Two saws, three trimmers, a backpack and handheld blowers. On non ethanol fuel and 80:1 mix I’ve had zero problems. The trimmers and blowers were built in 03 and have been used weekly for keeping up two school properties. I don’t know anything about high performance 2-stroke engines but Saber has been great for my stock equipment.

Having ground material off the piston it's left an edge on the ceramic coating. I suspect that is breaking microscopic particles off the coating which is then grinding between piston & cylinder. Notice how the scoring is exactly in line with the area of the piston that was ground off.

Hi Richard, It looks like the Stihl cylinder is in need of replacement for some reason. You could give the cylinder a couple strokes with a ball hone if their is enough coating on the cylinder walls to see if it could be salvaged just for giggles. I have saved a few with a ball hone. I do like the oil testing you do. I have converted over to Honda HP2 now. I was using Echo Red Armor(with great success) until I saw your testing of the HP2. I did my own testing and love the way the HP2 works in my saws. I'm running HP2 at 32:1 and see no carbon build up, in fact the HP2 started to clean carbon off of a couple of saws piston crowns.

Very common to see piston polish, especially on modern saws where they just aren’t made as consistently as the older saws where there were much higher standards - the 500i pistons are terrible from the factory. 661 cylinders and pistons too. My guess is that because the piston is coated, it’s far more obvious and shows what appears to be scuffing, but is actually just polish on a normal ally piston. Nothing you’ve done wrong here. It’s a combination of tolerances, modern manufacturer and a piston bedding in.

Hi Richard, always appreciate the work you do and information you provide to us. Damn, I feel almost as bad as you do after looking at that top end and piston skirt. I’ve got an old 034AV that has been beat up, put up and resurrected a few times and it does not look that scuffed. Yes, you know that I run Motul 800 2T in my saws, but I don’t think it’s the oil this time. Don’t get me wrong, I like the saber too at 40:1, but there is just something about that Motul smell. LOL. I’ve got a thought, and it’s not worth much as you know, but when you modified the piston itself you change the vibration dynamics of the system now and that whisker or two of weight reduction may be pushing you in a vibration characteristic that it was not designed to be in and that might be causing some additional movement of the piston on the cylinder wall. Since the saw is getting upwards of 14k in rpms. couple that with the customary M-Tronic unloaded 4-strokin and that might be just enough to be riding on a natural vibration peak mode of the crank making the amplitude of the vibrational movement of the piston worse. The Stihl engineers would have done the vibrational spectrum to see where the high points are and designed the components to stay well away from these peaks. It likely does not affect the system if you modify the cylinder port since that is not in motion like the piston, crank shaft and bearings. Other guys modify the hell out of the piston too, but maybe they just get lucky too. I think that saw will be fine with a polish and run your fancy Honda oil or Motul and see if the results are the same. Really enjoy your channel. 🤠

thats what you get for running a thin mix for break in. would you run 0W-8 in a fresh rebuilt car engine? then run the pis out of it like you did with the saw? i have an old 041 farm boss and the manual for it and it says to mix your gas with extra oil for several tanks during the break in time and not to run it too hard, I think it said use 20:1 for break in and 32:1 for regular use after so many hours. I have also read other manuals that say to run engines easy during the first few hours of use so they break in properly. I have always mixed my gas at 20:1 for all my saws and never had any engine go bad and I have cut lots and lots of wood over the past 25 years with those saws. the govt tells them to use a 50:1 mix so there is less smoke, they dont care if your saw burns up. I have used all brands of 2 stroke oil and even used 40 weight diesel oil mixed at 20:1 when I was out of 2 stroke oil and never had a problem. rebuild it and break it in right with 20:1 mix then show us if its scratched up

I can’t believe how picky people are about the type of oil that is being used. If the oil is rated they will all prevent wear the same. What’s more important is how the premix last when it’s stored for a couple months. If the carb diaphragms get stiff or too soft that’s when real problems start happening. Some oils will make diaphragms stiff when stored. Others like red armor will keep them in good shape after sitting for years.

In Husky and Sthil trimmers the piston stays decently clean but still get those hard deposits in the ports. Grabbed a gallon of Red armor last winter online for $55 and been running it this season and it has cleaned the piston back up and is a nice red film every time I check around 44:1 and ports look cleaner.

I know that editing sometimes creates “false impressions” so take this with a grain of salt. When you were ready to use the saw to cut, it appeared you started it cold and just full rev cut with it at WOT from stone motherless cold. Maybe you had warmed it up before hand and it was already warm, but it didn’t look that way to me. I’ve read somewhere that cold start, full on WOT into a heavy cut is the worst possible thing for a 2 stroke saw. Heat shock or something they call it. Apparently that’s not a new cylinder? (First time watching any of your videos), you said you polished out the cylinder with scotchbrite? Shouldn’t a cylinder have cross hatching from the cylinder hone? Perhaps it’s a combination of polishing the cylinder with scotch brite & heat shock starting it - that’s causing your piston scuffing? Watching you assemble the piston into the cylinder, I could see some kind of debris (looked like an oil soaked wood chip) between the two top rings. Could that be what caused the scoring? Could it have migrated around and caused that wide scoring pattern? Occasionally you do get a dud saw straight from the factory. We have bought a LOT of Stihl saws starting back in 1982 & using them commercially in our logging & milling business over the last 40 odd years starting with my very first new saw a Stihl 034 AV. This year we got a dud 661C brand new that cut two rings of firewood off a hardwood log, before it jammed open throttle, wouldn’t shut off when throttle trigger was released, and even when the kill switch was shut off. Had to nose plunge it into the log to stall it out to stop it. Luckily my lads missus was filming the new saw start up, for his Instagram channel - so he could show Stihl what happened. They repaired it, new piston, rings & crank seal, sent it back. Filmed it again, this time it cut 4 rings before doing the exact same issue. Sent the video - they took the saw back & replaced it with new one, which has operated flawlessly since. It’s the first ever “warranty claim” with any Stihl saw in over 40 years. Stihl were good about it, BUT without his social media channel & video evidence of the two repeat malfunctions, would our treatment have been any different? 🤷♂️ Out of respect the two videos of the incident were only shared with Stihl & haven’t appeared online anywhere. What the “issue” was that caused it, we never heard. But it shows that occasionally a lemon saw comes off the assembly line even with Stihl.
