I have been reading alot over int the Wahl Clipper Oil Experiment thread and decided it would be worth a try. I have a one month old Atlas Dash8-40B that is already having problems from poor pick up. So I haven't picked up any Wahl Clipper oil yet, but tonight I was in the garage running the trains and the Dash8 started running intermittently again. I cleaned the tracks, cleaned the wheels and it ran great for about 3 or 4 passes, then back to crap. Well I got this great idea, I figured how special can Wahl oil be compared to other oils. So I had a small bottle of some oil I picked up from the LHS to lube my engines. It is made by Perfect Part Company, and they call it Light Oil. It works great for keeping everything lubed and it was cheap, $4.79 for the bottle. Well I was getting fed up with the poor running so I figured I had nothing to loose. I didn't even bother cleaning the rails first. i put a small drop on my finger and ran it along both rails in one area. I ran the Dash8 across it and no change at all, at first. After I ran it back and forth a few times it was like a whole new engine, well it still practically is, but it ran perfectly like it should. So I applied the oil to a few other spots around the layout and ran the train. WOW what a difference. I am sooooo surprised at the results, and there wasn't any wheel slipping. So I ran the Dash8 for a while at about 30 percent throttle on my DC power pack. After about 20 passes of flawless running I put the Dash8 and the GP40-2 together and hooked up my 5 Walthers intermodal cars which are all metal and weigh quite a bit, and 12 more regular box cars and such. I was able to run the entire consist at 10 percent throttle all the way around the layout 3 times. It was literally a crawl up the 3 percent grade, but it never stalled once. Before the oil I couldn't run pretty much anything at less then 15 percent with out it stalling in one place or another. And I have zero hiccups when going through the yard across 5 turnouts in a row, which was a big problem area. The bottom line, I am not sure of the long term gains, but I can tell you that this works just as good as how people describe the Wahl oil. It might even be the same stuff. Who knows. I don't know how much the Wahl oil costs, but at $4.79 a bottle for this stuff, you can't beat it.
