I think the tackifier difference is why motor oil fared better in the wear scar test by Project farm but did not do as well on the actual sawing tests, judged by wear on the links. The motor oil had more EP additives, but the lack of tackiness probably caused less of it to remain on the bar.
If you run a saw with tacky bar oil like Durex and then run it with something thin like Walmart super tech what you will find is there is almost no differance. In fact the wood your cutting matters much more. I've cut standing dead red oak that had a three inch layer of dry rot that turned to powder when cut. No matter how much oil or what type the chain is dry when cutting that.
Don't know about using one enough, I usually try to sell a saw when the chain gets dull.
True. I have only worn out 1 bar, though that was after it had been swaged and ground a couple of times. I suspect most people just throw the bar away when it cuts to one side or gets wallowed out. I generally use the cheapest bar oil I can find also, though the PF test was rather interesting.
I know I bag on PF alot and he deserves it, but I did find the test interesting for one reason. It proved that Zinc(ZDDP) as found in motor oils, although not a EP additive, is an effective antiwear additive on his test rig. This is interesting because essentially using such a rig to test motor oils is skewed by the zinc content. As such a uncertified motor oil like Amsoil will always do better than those that follow API mandated zinc/ash limits.
Have you seen the long-term reports on oils by others? I have seen several. There is a guy named Flagg who runs a saw repair shop and has a YouTube channel and he has repeatedly seen better results from Amsoil than any other when he has torn down dozens of saws. Regarding PF, you do put it down a lot, but you do not specifically say what is wrong with his tests or make suggestions on how to achieve relevant test results. That makes your statements lacking in substance. I remember you specifically did say there is no point in doing the volatility test as there are already Noack test results published for most oils. However, in the world of science, when test results are reported, other scientists all around the world will try to repeat the same test to see if they got the same results. That is how anomalies and lack of reproducibility are weeded out.
I have stated exactly why I have a problem with PF's home brewed tests.
How do you know they don't buy the same base stocks from Shell, Mobil or Chevron? Possibly one or more of those are willing to sell base oils at a premium price, thus making more money that they do selling their own formulated oils. BTW, PF just released a video on diesel oils. Once again, Amsoil won on lubricity, lower power draw and lower volatility. It lost on cold flow.
That is who they buy them from no doubt. However, the majors hold back the latest stuff and make it proprietary.
So you still wish me dead? Your wish was completely out of line.
I have never seen one there.
I never said that.
What you said was that the world and this forum would be better off if I were hit by a truck, which would presumably be fatal. To me, that expresses a wish on your part. What a miserable human being you must be, to say something like that!
Your presuming that.
I have never had a oil related failure with anything. I will never comprehend how I did this without using Amsoil exclusively...
To me, the biggest benefit for high quality synthetic oils is the extended drain intervals. I have normally changed oil on my cars every 25000 miles, changing filters every 12,500. With non-synthetic oil, I used to change it every 3000 miles. For my tractors, it is every 200 hours. For my diesel trucks, it was every 25000 miles until my current F350, which I change every 10,000 miles on the recommendation of Amsoil due to possible fuel dilution of the oil. I normally keep my vehicles for about 250,000 miles, though I got nearly 300,000 out of a Saturn; when its timing chain broke, I opted not to get it fixed, as the cost would be more than the car was worth. Its upholstery was pretty worn out by then also. I did not get so many miles out of a diesel Suburban (pre-Allison) or an older F250 with the horrible 6.0 liter diesel. But my problems with those two were not oil related. I imagine you have heard all the horror stories about those two engines, so I won't get into that here.
Those extended drains are not because Amsoil makes a magic diesel oil. With proper UOA Rotella,Delo, or Delvac synthetics will do the same thing.
