Amsoil HMlike what?
Thanks for your input sir. I'm a C-17 IP here at the AF schoolhouse. I've followed your aviation content here for some time, thanks for sharing from your experiences and expertise.Your use case seems to be pretty low in demands on that engine. Why not explain that to the builder and see if the have an alternative suggestion. It's not as if you plan to tow a 10,000 pound trainer over Colorado mountain passes in 100 degree weather. It seems as if this is a pleasure vehicle. Now that being said, HPL has a number of interesting offerings in 5w-40 and 10w-40. I cannot see a need here for a 20w-50. @Pablo might also have some opinions and suggestions for an Amsoil alternative.
@Cruisin'n5thgear I believe you have me confused for @Astro14. He is the pilot and I am the astronomer.I've followed your aviation content here for some time, thanks for sharing from your experiences and expertise.
Engine builders often don’t know much about oils and often don’t have good advice. Like the recent thread about an engine builder who doesn’t recommend synthetic for the first 9000 miles, despite the fact that many new cars come from the factory with synthetic oil.It’s a mystery to me that the OP spent a lot of money to have a well known engine shop build a street performance engine but yet ask strangers what oil to use. Apparently the shop told you what to use. If you trusted their expertise to build your engine then trust their specific directions for oil.
Given the bearing info, I would prefer a 5w-40 or 10w-40 oil if this were mine. HPL Premium Plus, HPL Euro, Amsoil Z-Rod, Driven Racing HR, Rotella T6, or Valvoline VR1 lines would all work pretty well for your setup IMO. Doing oil analysis to watch oxidation in an engine that sits, you can safely find the sweet spot in how long you can extend the oil of your choice before draining. As you said mileage won't be the limiting factor.
We can agree to disagree. When a professional engine builder* has a warranty return that he is expected to “eat” because of improper break in, incorrect oil used, or overheating due to owners’ negligence he knows exactly what advice to give to lessen the chances of a return. Sure, maybe he doesn’t know the in-depth formulas for oils but he knows what’s working…Engine builders often don’t know much about oils and often don’t have good advice.

Yes I have. All you Astro guys are cool@Cruisin'n5thgear I believe you have me confused for @Astro14. He is the pilot and I am the astronomer.
You said it better than I could have. I value the expertise here and want another set of opinions. Obviously will run his specification during warranty.Engine builders often don’t know much about oils and often don’t have good advice.

@Cruisin'n5thgear It's even better when @Astro14 and I have a conversation and the casual observer thinks that one of us is talking to himself.Yes I have. All you Astro guys are cool![]()
Oklahoma can be hot but not AZ 465 days a yearClearances aren't necessarily loose enough that I'd consider a 50w. May perform better with 40w or even 30w. Run what the builder recommends through at least break in and pay attention to oil pressure. 50w could keep it pegged on the relief spring when cold, and more pressure than needed when hot. You're in a hot region so maybe 50w is warranted. The pressure gauge will give an indication of weight. I can't recommend any particular oil over another, not knowledgeable enough for that.
I have an oil pressure gauge but not temperature. Will put that and a trans temp gauge on the list of new gauges to add.Hopefully you have both oil pressure and oil temperature gauges installed. These should tell you much of what you need to know. Keep the pressure where it needs to be at minimal oil temperature. Oils that are thicker than needed will run up your oil temperature for no benefit.
