Amsoil’s 5W-30 Fully Synthetic Oil

Bottle of Amsoil’s 5W-30 Fully Synthetic OilTrue story.  If this is one of your first times reading about Amsoil and their 25,000-mile oils then I think you will appreciate this article. It was 1996 and I accidentally stumbled upon an Amsoil Dealer near my neighborhood and I started asking him some questions. Well, one thing lead to another and I was soon purchasing 5 quarts of 5W-30 and an Amsoil oil filter.

Most people who stumble upon Amsoil and have had the 3,000-mile interval ingrained in their head find it nearly impossible to believe an oil can last 25,000 miles. Yes, I was one of them, but who wasn’t.  Even with this disbelief I went ahead and switched my 1989 Toyota Tacoma with 35,000 miles on it over to Amsoil. Immediately there was noticeable difference in the performance of my truck.

Along with installing the motor oil I also ran a bottle of Amsoil’s Performance Improver through my fuel tank.  After three fill ups my mpg went from 18 mpg to 21 mpg!! I was impressed, but wanted to keep testing.

Since I already had a background in automotive maintenance it was an understatement to say I was impressed with Amsoil’s 5W-30 synthetic oil. I still had something I was uncomfortable with……yep you guessed it…….that darn 25,000-mile interval. My truck was running as smooth as ever, but at the 8,000-mile mark on the oil I panicked and changed the oil, but still using Amsoil’s 5W-30.

I actually told the Amsoil Dealer that I bought it from that the oil was for someone else. After a while he figured it out and he knew the oil was really for me. At this time he sat me down and went a little more in-depth on how and why Amsoil can achieve such long intervals. After understanding this a little more I have been changing my oil once year now for over 20 years and have never experienced any problems.

So if you can relate to what I went through back in 1996 you can rest easy and know you are not the only one who thinks changing their oil every 25,000-miles is a crazy idea. Amsoil has done their homework and you can be certain that if they produce a synthetic oil that can last 25,000-miles take their word for it.  Amsoil has been doing this since 1972 and they are the clear leader in synthetic oil technology.
