I'm pretty much use it in most everything, mainly there motor oil, but some of there other stuff also. I'll give a couple of examples on why I use it.
I have an air compressor that is an oiled unit. How many people change there oil in a compressor very often? Not me. I changed it about 2 nights ago. This thing is about 10 years old and I've only changed the oil once. It always looks clear when you look in the fill plug. I ordered some Amsoil compressor oil and when I drained the old, I was shocked. All the crap had settled to the bottom and it looked awfull. I hoping the Amsoil stands the abuse a little better.
Another is the gear box on my mower deck for my
BX2350. You are suppose to change the grease in it every 50 hours I think. I probably had over a 100 on it when I changed it. I figure using Amsoil will allow for a little longer interval and make up for the fact that I don't change it as often as I should.
A lot of vehicles say change the oil every 6 months. I don't, I go more by the miles, and with Amsoil I don't feel so bad by extending this out to 7000 miles or a little more.
So if your one of those people that change your oil every 3000 miles in your vehicles, do the maintenance on your tractor on time, take care of your small engines on time, your wasting your money going to Amsoil. For me, where I have 4 vehicles to maintain, a tractor, half a dozen small engines, it just makes sense. I'm not saying it lets you skip regular maintance, but if Amsoil allows me to only change the oil once a year in a lot of my stuff, that can save me a lot of time in a year.
