I switched to Amsoil 10w30 about a year ago. My 6.0 psd starts quicker and is way quieter than it was before. I would not have believed it if I hadn’t done it. When I order it’s on my porch in 2 days. Very happy customer
Bottom Line
Yes, I would recommend this to a friend.

I do hotshot/RV transporter and have over 320km on my truck now. Sent oil sample to Blackstone and I was amazed but not surprised at the results. I maintain all my vehicles well so I have high expectations. Will be switching to signature series to improve protection of engine that much more.
Bottom Line
Yes, I would recommend this to a friend.

Best oil on the market

The only oil I'll use for my diesel. Fast delivery and received what I order everytime.
I have always used Royal Purple 15-40 in my diesel engines but decided to try Amsoil 10W-30 after watching a head to head comparison online. After the oil change to Amsoil and Amsoil filter my F-350 Superduty seemed to quiet down a bit. This might sound crazy but she seemed to say thank you by running smoother and quieter. I highly recommend Amsoil oil and filter.
I use this oil in 6.7 and 6.0 Ford engines. As well in John Deere tractors. Oil works flawlessly. Will continue to use
Bottom Line
Yes, I would recommend this to a friend.

diesel oil that is perfect for cold weather

this oil is perfect for those extreme cold days, used in truck that normally recommends 15 -40 . This oil helped with cold startups in weather that was at freezing or below. We had zero issues with startups even when it was -39 out..
