What a sad thread. Poor OP is doing all of this searching for a holy grail oil to try to keep his cams intact in the year 2025. I really want to love KTM, they make wicked road machines. That being said my personal experience with a brand new 390 duke, these issues and the fact they still want...

I'm actually 2200 miles into a fill of HPL motorcycle 10w-40. Working on getting everything switched to HPL, eventually! The Amsoil is awesome too, I have a UOA on here at 4k miles it was like it hadn't been touched.

I must say I really do like Fortnite’s videos, however, that o-ring test is just bad. Take an application like my Volvo penta outdrive on my boat run in saltwater. O-rings all over it keeping oil in and water out and they go years and years without fail running around the puget sound. A properly...

This is one of the main reasons myself and I'm sure others here run HPL, for the rings. I was just getting at the fact that a clean valve train is just a point of pride for most of us on here that are hugely into maintaining our vehicles in tip-top shape, for whatever each persons reasons are...

True. Most posts/concerns involve the valve train area, I should have been more specific.

C’mon folks, he’s like most of us here! We all know varnish is not in the least bit detrimental, it is however, an eye sore for all of us that geek out over our engines and oils. OP: run the full fill of HPL like several have stated and motor-on happy

The 10w-40 offering from HPL will be just fine. Run it with confidence.

I’ve got an email into them, let’s see what they come back with…

I will certainly be posting it. Manual calls for 10-30 so 10-40 is definitely sufficient.

I’m running the 10w-40 HPL in my ninja and I wring its neck everyday on my commute. Coming up on a 2k mile midpoint UOA just to see what’s going on. I fully trust this oil either way though.

Keep doing what you are doing op, that oil held up fine judging by the rather boring UOA.

We are on the same page then.

No, I won't be doing that. Far too many variables and I don't have the time to spell that all out. Now to your point, if one deals with new/newer vehicles and dealers then yes, chances are you are going to take a bath on a trade-in because, well, dealers. On the other hand, if one deals in the...

I get it, you did the research though. Many don’t, and are just pulled in by the bells and whistles.

If it’s a vehicle that takes you to and from work and other important places, why risk it? If it’s a hobby car then great, have fun.

I see this everyday. Burning oil out of the tailpipe, lots of strange noises, engine struggling to accelerate, it is quite commonplace. Even nicer, newer vehicles all over with that very subtle blue smoke out of the tailpipe, owners probably have no idea! Big part of why I choose to run HPL is...

No, no it’s not. If you own a crap engine that requires ~3k oil changes and even then no guarantee it won’t destroy itself by ~100k, absolutely worth a swap. Sure, oil, filters, and preventative maintenance will certainly cost more, however, the reliability hit is the worse as most of us really...

#2 on the sheet above is the same fill at 5950 miles. #1 was Amsoil SS on a different fill.

Nope. Much different product than your $24 offering though.
