Hello, I am new here. I have been lurking here the past couple of weeks. I was glad to find the information on the Toyota 0W20. I have used Amsoil for almost 20 years. I recently got a 2013 Highlander with the 3.5 and was impressed with how fast it started, how quiet and smooth it ran, and how well it ran. The engine turned over almost instantly. The first thing I did when looking at the vehicle was check the oil. It felt different to me. Super slick and very thin. Based on what I have read here the last couple of weeks it seems to be hands down the best synthetic for the money. Its flow characteristics and moly content is impressive. I have had Amsoil in my 2011 Honda Accord 4 Cyl for 40K. I am thinking about experimenting and using the Toyota 0W20 in it. I drive a great deal, mostly highway miles. I am interested to see what the oil monitoring system does with the Toyota oil in it. I usually change my oil at 50% or around 5-6000 miles because I am severe service. I can drive 200-300 miles a day. I am an old lab rat and love to compare/contrast different things, especially when it comes to cars/engines.
