Tricky salesmen, they always have some angle or trick up their sleeve...

Sad, Schaeffers is probably a good product, maybe just as good as the other better brands, but trying to peddle it with snake oil tricks would turn me off from ever buying it.

Schaeffers 15w-40 engine oil is a good product but not as good as they say it is. IMO. Idc about the bearing test. In our 966 Cat engine the UOAs looked somewhat better on paper compared to the fleet oils you find on the shelves at Walmart but for the duramax there was no noticeable changes in the UOAs between the Schaeffers 7000 and the mystik 15w-50 jt-8 we run. After we use this Schaeffers up I'm staying with the mystik 15w-50 jt-8 synthetic blend as it does a good enough job protecting our duramaxs and the HD equipment we run. No need in spending $3 a quart more and not getting the results we were looking for in the duramax engines.

Have to ask my boss if they pulled this stunt with him. I do like Shaeffer, but its harder to come by then my Delvac. Which has a history of GREAT results with the Dmax.

I use to see sales men at flea markets use that machine to sell some bogus additive they where pushing. Half the crowd around them where plants to hepl push the product.

You should see what happens when you put Monster diesel in the machine, the bearing speed increases with more pressure

Just a quick update. 2 oil changes on my LBZ with the Shaffer's oil @200k miles. I used to burn about 1-1.5 quarts between oil changes. Oil consumption has dropped significantly, I'm at about .5 quarts on the last oil change. Checking the oil level now does not show any drop in oil level and I'm about 1k miles away from my next oil change. Looks like whatever they are using is working. This is without any additional oil additives.

What are your intervals? I avg 1.5-2qt per 10k 95% towing.. I'm sure it would be less if I just DD the truck.. I'm usually either delo 400 or delvac 1300 both of which I can get 99% of the places I got and both within $1.00 of each ither

I know this post is old, but I can’t resist. I have to disagree with all the nayayers here, implicitly. The “trade show” machine proves a valid point, anti friction, but there are other points that you cannot bench test or show in 10 minutes- high detergent package that keeps the engine very clean, reduced oil temp, higher oil psi, and better mpg. The machine is just a quick and easy to understand example. I have a large bank of UOA, a few VOA, that show the benefits I am getting. I now change oil every 20k with filter change at 10k. And by the way, used oil (10k mi oil tested) still works on that machine just as well. I’ve seen it with my own eyes.
