Replacing WS fluid.

Used this oil to replace Toyota WS fluid, unable to flush fluid on this particular transmission, so I’m replacing 4 quarts at a time (total system holds 8.3 quarts). On this first fluid replacement, shifts are more sluggish and less precise than with old WS fluid. My guess is perhaps the two fluids are not blending well, I hope it will improve with subsequent fluid change, which is four more oil changes, with 500 miles between each change.

Had a new motor put in my truck last spring wanted an oil I could trust to keep it running like new so my research lead me to Amsoil now my go to oil for all my oil needs.
I used Amsoil 30 plus years ago in my 2stroke dirt bikes always ran great, & have used there Oil on & off since/ for the last year I have joined & been using there Oils exclusively & Very Blessed .... Awesome Oil
Well I own 2015 CNG Impala. 3.6L naturally aspirated engine. I change my oil around 20,000 miles. CNG makes it more acidic, per amsoil. I've been running amsoil since the car had around 30,000 miles on it. (First year free engine oil changes) It now has 112,000. So far so good, no issues, engine purrs like a kitten, I am going to run this car, and keep it until it dies!
Bottom Line
Yes, I would recommend this to a friend.

The cream of the crop! My favorite oil brand for Amsoil

I used this oil in my 96 Mustang GT and my wife's 2010 Hyundai Elantra GLS. They are both in the 100k mile range and they have protected my engines through harsh environmental elements in New Jersey. We are a four-season state and that means you need maximum protection for all temperatures AND driving conditions. I love Amsoil.

Watch all the real world tests, Amsoil is head and shoulders above the rest of the competition when it comes to synthetic oil performance. Worth every penny.
