As soon as I saw 250 words, I stopped. What are you talking about?Todd (Project Farm) is a good dude. I've chatted with him many times in the comments of his vids. Just a hard worker like the rest of us, except he found a much needed niche that Google compensates him extremely well for. He turned me on to Diablo cutoff wheels - I've tried just about every single brand out there and haven't been impressed. When the Diablo won his shootout, I bought some. He wasn't lying - these things last at LEAST 2x longer than ANYTHING I've used before. I run a small shop out of my property. I've cut hundreds of bolts, exhausts, hardened steel bearing races, you name it. He also got me to buy a Audew jump pack after that won the jump pack shootout. I've started DIESELS with NO BATTERY with this thing! I don't know about you, but I think that's friggin impressive! Thing is 1/100th the size of that cart charger I bought at Sears 20 years ago! Cost less than half what I paid for it, too. What a time saver when I can drive a vehicle up instead of winching. I even winched a Lexus RX350 onto my dovetail trailer on a hill, TWICE (winch failure caused it to roll backwards until I slammed the freespool selector back in gear) with a dead deep cycle battery using this pack!! Has to draw at least 200A under load! When I got the vehicle up there the 2nd time, it wouldn't work anymore. Contacted the company, and they sent me out a replacement set of clamps with the little computer gizmo inside that plugs into the jump pack itself. Been working great since! I've driven cars home with no battery just clamping this thing in (just have to use electrical tape so you don't burn the vehicle to the ground, lol). Several other products he tested that won other shootouts I had already been using for years, and his all his test results matched my experiences to a tee. Just my .02.
As far as saw oil contaminating anything ... if the general public knew the scale of oil dumped every day on construction projects, they'd drop and convulse! One blown hydraulic line on a big excavator can blast 5 gallons into the dirt faster than you can blink! Happens every single day on every single project all over the country at some point. I used to drive recycling trucks in a big city - I've laid down the contents of a 55 gallon drum myself over the course of 5 years, just due to leaks and hose failures. Typical big company - let things go until they fail. I've dumped at least 10 gallons on my own property in one season, thanks to my 60+ year old backhoe between leaks and hose failures. Who knows how many the previous owner did - there was a rainbow sheen on the swamp out back here for the first 15 years I lived here. He got his tractor stuck over there cleaning up the property for me before the sale date, so I know that's where it came from. Add up how many cars and heavy trucks drip all types of petroleum products on the highway, and it's probably a 55 gallon drum per mile on EVERY expressway in America. Chainsaws are MINISCULE in this arena. I guarantee any water that comes out of ANY well has petroleum products in it at some level. It's unavoidable. People are still living to be 90, so it's not as big of an issue as the powers that be would have you believe. Bacteria and natural breakdown dispose of oil faster than most think, too.
As far as my saws go, I run cheap Poulan oil bought by the gallon from Walmart (same stuff Harmon was just talking about!). The stuff barely moves in this weather, but it still keeps the chain wet. If I didn't burn used motor oil for heat, I'd probably use it in the saw, too.
