Yep 1BadAction, it's another oil thread. :D
Just thought I'd post some REAL world feedback on this oil, which is packaged by Warren Distribution for Walmart. My father has run the TC-W3 oil in his 1965 Yamaha 250 for years. He bought the bike brand new and it has just under 50,000 miles on it. It's on the third set of rings, which were put in probably 10 years or so ago. The second set was only put in because the original rings lightly rusted up when it sat for a couple years after a minor accident in the late '60s. Everything else is original.
At any rate, last year he had the clutch apart, and had the oil injection adjusted incorrectly when he put everything back together (it runs off the clutch). He discovered a short time later that it was getting very little, if any, oil advance because of the incorrect adjustment. It was running nearly at the dead idle mix all the time, probably 150:1 at the richest (it is designed to idle at 200:1). At the same time, he found that a check valve in the oil line going to the one cylinder was bad, and that cylinder was running on virtually no oil at all (line was full of air). The crankcases are separate so there is no way that it even got any oil from the line on the other cylinder that was functioning. The bike had been driven approximately 100 miles by the time all of this was discovered.
Well, he was sick over it, and busy with other projects, but finally pulled the motor apart last week...the wrist pins mic with NO wear over factory specs. The pistons are within specs and one had just a small scuff that cleaned right up, the rings are fine, cylinder walls are fine, bearings are in perfectly good shape. The motor was basically driven throughout the rpm range as it would normally be driven, for 100 miles, with a "very lean" mix on one cylinder and a "negligible residue" on the other. The little bit of oil it was getting was none other than the SuperTech TC-W3, and it lived. He put the motor together, blocked off the oil injection for the time being, and is running it on premix. Runs fine.
No, it ain't a 300 Drag. But it is air cooled and turns 8000 rpm when you get on it, and the motor was high mileage to begin with. It's a miracle that it survived, let alone in serviceable condition. Makes me wonder how many of these "oil related failures" are mislabeled and fall into the category of "operator error". ;)
