The delivery was vey quick. Unfortunately this product has been discontinued because it was ideal for my vehicle which requires at least 3000 ppm calcium detergent. Hopefully one of your other products meets this specifications.
Bottom Line
Yes, I would recommend this to a friend.

I’ve owned my 1998.5 Dodge Ram 3500 Dually since 2000 and, although I tried Kendall Super D3 in the beginning, I wasn’t quite pleased with it and the availability of it. So I changed to Amsoil and I have never looked back. I now have 366,000miles on my truck and it still runs smooth as silk with no engine problems whatsoever. I also run Amsoil gear oil in the front end, reared, transmission, and transfer case. I change the oil on an extended mileage plan in conjunction with my mechanic and I simply could NOT be more happy with this product. Combined with an Amsoil Bypass filter system my truck will very probably outlast me!!!
Bottom Line
Yes, I would recommend this to a friend.
