I could do a straight weight in the summer, not all year though. Sounds like HPL may try tweaking the blend for me once they verify OAI’s results. I changed the oil though so will have to wait until the next fill.

Sticking to 2k ish intervals now, trying the 15w-40 HPL next because why not! May eventually return to the Amsoil. Thanks for everyone’s input.

Not necessarily. My older F-150 with the 5.4l modular had such a high threshold for misfire counts to pop a check engine that I had to go look at pending codes because something was just off. Sure enough, plenty of misfires lined up, no check engine illuminated.

They did yeah, because they are terrible at reading my submission info so I sent them the oil spec sheet and they reran it.

That’s where the conversation is going with him so far. I have no problem with 2k-2.5k mile changes, that’s a little under a year for me. Just good to know what my changes need to be.

I agree it should really do better, especially with what we are seeing from HPL in other applications.

Yeah it’s used up. He’s going to keep a 14k mile interval.

Thank you! For consistencies sake we have switched most of our vehicles to the 5w-30 as to not have to keep too many oils around. After this I'm not sure it's needed!

This is what I was thinking too, even though it was on a similar death spiral it seems it would hold up better. Bonz, The only variables I can think of are that smaller sump and keeping it heavily loaded most times. Would be cool to do one long highway run on a fresh fill and test it, I bet it...

No, the other one on there is Amsoil Metric 10w40. I'm with you, a bit surprised that HPL didn't hold it's own, and nothing changed in riding habits or the bike between Amsoil and the HPL. Now, to give the oil some credit, I ask for everything this motor has everytime I ride it. I weigh 220lbs...

We haven't seen this with HPL though. Wilson already chimed in so no need to call his experience up!

Looks like this engine and my right hand tear up oil! Bit surprised, however, now I know what OCI should be so that's good. Have 5gals of HPL 15w-40 HDEO sitting here so may experiment with that later on. Enjoy!

My dads truck, he ran this stuff hard! Broad range of driving conditions represented here: Hills, mountain passes, flat freeway, trip from Washington to Wisconsin and back, hauling RV and boat, small trailer use. Ready to change for sure, held up decent though. Once again, OAI didn't read the...

For what it’s worth, HPL steered me towards their CK HDEO 15w-40 when I inquired about lube for my boats. He specifically said that was his recommendation because of the sheer resistance. So HDEO it is in the boats! One 3.0l penta, one 4.3l vortec.

Plenty of life left in the oil to continue running safely, why change it? That’s a great report.
