So, Back in the early 80's got a 78 GMC Jimmy (just like a Chevy Blazer) that had a 250 inline 6cyl. Got some Slick 50 from my brother. This was when it was not available at parts stores. Did an oil change, all but the last quart. Started it up and poured in the Slick 50. Sitting there idling the idle speed increased within a few minutes so much I had to adjust it lower on the carb. Then drove the Jimmy around for 45 minutes like the instructions said. Thought it was cool that it reduced the friction so much it required re-adjusting the idle. Then didn't really think about it.

My parents would use my Jimmy to drive 70 miles to a dairy and get 1000lbs of cheddar cheese, a distribute it to friends and co-workers. It was like a co-op thing. It was good cheese and much cheaper picked directly from the dairy.

The next trip I asked them to stop and get the oil changed because it was time, I didn't have time, and it needed changing before hauling 1000lbs. They stopped on the way out of town at a Jiffy Lube. Mom noticed they put in the wrong weight. They drained it again and put the right weight in. Then they went on their cheese run.

I swapped cars, picking up my Jimmy on the way to a night class after work. Dad told me it kinda started clattering when they go close to home. Left because I just had time to make it to class. Drove the 11 miles to class and in the last 2 miles it started clattering. Parking for class I quickly checked the oil and the dipstick was bone dry. Fretted thru class knowing my parents had just totalled the motor on my Jimmy.

A girl in class overhead me and told me she had picked up a couple of cases of oil on sale and they were in her car. Ended up buying 7 quarts from her to top it off. That meant even the oil filter was dry. Drove it home with no issues. In fact drove it for another year with no issues when I traded it for my 914.

6 years later I sold the 914 and got another Jimmy. Notice they had Slick 50 at an auto parts store. Picked up a quart and did the treatment on the Jimmy. Noticed the Slick 50 looked different as I poured it in and the idle didn't change at all. So was very disappointed and figured they had changed the formula.

Now for the interesting bit. Found a product called Xcelplus. The guy that invented Slick 50 said he sold the name, but not the formula. So, Slick 50 had been changed! Said it was now available as Xcelplus. Wonder if it is really the same as that original Slick 50?
