Factory fill of Toyota WS fluid from my Tacoma taken at 40,940 miles. I did a pan drop in association with this sample and replaced the filter assy. which is just a glorified fine mesh screen, not a fiber/barrier type element. I also did the cooler line exchange method after reassembly. I don't have and can't seem to find a VOA out there for Toyota WS fluid for comparison; if anyone has one I sure would like to compare this sample against it. Now that I am out of warranty, I did a drain, fill, cooler line exchange with Amsoil Signature Series Fuel Efficient Fluid so we'll see how it does over the next couple of years and I'll check it with a sample.
