Now that I’ve been setting up my AMSOIL booth publicly again, I’ve had people come up to me and tell me their experiences with AMSOIL, how it saved their engine, cooler temps on their motorcycles, etc. These range from things they have noticed, to major issues that were prevented. I’ll start off my experience:
Back around 1999 I bought a 1989 Ford E-150 Conversion van with the standard Ford 5.0 engine. I converted it over to AMSOIL and then in May of that year for my oil change I used the Series 2000 0W-30 (now upgraded and called the Signature Series 0W-30). Around July of that year my water pump went out. I drove approx 30+ miles to visit my parents as it was just starting to act up but didn’t turn into a waterfall until I was there and refilled the radiator before leaving. On my trip back I was out of fluid almost immediately, but needed to get home. I had read and been told all sorts of similar testimonials, that I decided to give it a shot and hit the highway. I believed in AMSOIL so it was time to test it!
I traveled about 3/4 of the way when she started to get sluggish and I pulled off the next exit and inched along until it wouldn’t go any further and had to stop. I let it cool for about half an hour, made and attempt to add a gallon or two of water from the convenience store which turned immediately into steam, not even enough was left to drain underneath. I managed to get her home the last few miles.
The next day I did have it towed to a friends shop where we swapped the water pump out. I told him to leave the oil in, which he wanted to change for having been beaten on so hard and even more so in the Florida summer heat. The van ran fine after…until around February the next year when I developed a leak again somewhere. I couldn’t find it and would fill the radiator before heading to work the 8 miles, then fill it for the trip home. Temp gauge was always pegged about halfway again. With my work schedule, I had to do this for about 4 days before I was back in my friend’s shop. We managed to trace down the leak and fix it.
May rolled around, one year since the oil change and about 11,000 miles later on the oil along with those two incidents. This oil was rated (and still is) for 35,000 miles or one year drain intervals. I sent a sample off for oil analysis after i changed the oil. When the results came back, I was amazed that the results didn’t look much different than previous ones with no severe problems like I had encountered. Their recommendation: good for continued use!
This was my first “real” test of the AMSOIL quality. I have many other stories from customers and friends that I will be sharing over time. Do you have one you’d like to share?
