Anyone running amsoil 5w30 year round?

[Lococoin]

I just switched to the series 3000 HD diesel oil in a 5w30 weight for the canadian winter. According to amsoil they say that you can run it year round instead of the 15w40. I am a little worried that the oil will be too thin in the summer months and was looking for some feedback.

Thanks

I have run Amsoil for years. If they say you can run it, then you can. You have to trust the science of lubrication.

The main reason for you switching to the 5-30 is for better flow properties. The oil is a multiweight oil so the actual weight of the oil when cold is 5. The 2nd wieght is warm temp weight. The 5-30 HDD is actually a much more stable product then the AME 15-40 Diesel marine product. The flow properties and protection are better with the HDD. You are very well taken care of with the HDD 5-30.

I Myself live in AZ and run the AME in my PSD, but I run the HDD in my gassers. Yes Diesel Oil in a Gasser!!

I run the series 3000 5w-30 year round in San Antonio, Texas. I use the oil analyzers from Amsoil to check usability for extended drain. Never had a problem with the heat, and the report always comes back "continue to use". I use the double oil filters from Amsoil, one bypass, one full flow. I change full flow filter at 7500 miles and change both at 15,000 miles.

how often do you analyze the oil and how often do you change it? If you dont have any problems in Texas, im sure it wont be an issue up in canada.
