Not Sure About AMSOIL?
OUR TESTIMONIAL
I personally was skeptical before using AMSOIL but figured I would give it a try. We own a 2011 Ford Expedition with the 5.4L Triton. If there was anything to be wildly known about this motor it is that the passenger side lifters do not get enough lubrication and will begin making a ticking sound due to metal on metal contact. I had heard about AMSOIL being able to provide lubrication to parts of the engine that normally don't receive it from standard oil brands. Once our 5.4 Triton began the lovely ticking, I ordered 7QTS of AMSOIL SIGNATURE SERIES 5W-20 and did an oil change. It was a night and day difference when I started the motor back up. The ticking had completely disappeared and now having clocked 10,000 miles since, not a tick to be heard from in that motor, plus the MPG increased so that was a plus. I became hooked with AMSOIL products that day and want to give every vehicle I come across the same treatment.
Here you can find some links to the AMSOIL website where they explain & show the results of their products and why Witty's Garage trusts the American Made AMSOIL Company for all vehicle fluid & filter needs.
