Three 0w-16 choices I am considering next.

Unfortunately, it doesn’t show in portrait view on mobile browser. On mobile, it will show when the phone is positioned landscape.

Believe it.

Ahhhh, I was unaware of that issue with mobile, I'm on desktop like 99.9% of the time.

And is it only an error when it differs from your understanding of a given subject? Are others not allowed to have an opinion which may differ from yours, and they could be totally wrong? Or is it better you show your "expertise", not by trying to educate, but ridicule?

If you want to be political, then your Opinion can hold the same weight as someone else's Opinion. However, Opinions and Facts are weighed very differently when it comes to Science. When you drop in to a group leaning toward Science acting as if your Opinion is as good as established and knowledgeable Science-based members, you may experience immediate pushback. How you respond is totally up to you.

Understanding of a subject comes from reading and understanding what is read. BITOG's primary reason for its existence is to help educate on the topics of lubricants and tribology.

Is there a specific lubricant or tribology question you would like to discuss?

No thank you. I appreciate the knowledge and passion of you and others who've spent literally years helping to educate people.

On second thought... is HPL's Premium Plus 0w-30 a good choice for use in a new Honda Pilot which lives in central Texas and does some light towing (up to 2k lbs)?

Apparently, for the 2023 Honda Pilot, the recommended engine oil is an SAE 0W20 synthetic engine oil.

A 5W20 is the next step up as both are 20 grades. A 0W30 will work but you may suffer a slight mpg decrease.

I would recommend the Severe Service schedule for oil change and filter intervals.

Fuel's interaction with the lubricant is complex. It directly reduces kinematic viscosity, as one would expect, but as @DirectRejection noted, can also impact the chemistry, such as degrading the VII polymers that boost KV as well the PPD's that prevent wax formation at low temperatures and may also reduce the effectiveness of various components of the additive package.

Fuel's impact on HTHS is less than its impact on KV, because HTHS is measured under conditions where the influence of the VII polymers on viscosity are already reduced due to shear and at a higher temperature, so your starting point is already considerably lower. You of course get some dilution effect, but the magnitude is considerably less.

Does fuel in the oil cause more wear? Not wear because of viscosity loss, but wear just because fuel gets on the surface of pistons? If yes, then what is the remedy?
I am asking this because I saw a Project Farm video where the oil with fuel made the machine make a nasty sound and left a big scar.

I to wonder the same question Sienna dude is asking,,, as my 2024 Subaru Cross Trek has the fuel dilution problem, I currently have PUP 5w-30 ( a thin 5w-30) in it and seems to help and run fine , as the engine is to have 0w-16 in it, with fuel dilution it was like water when I drained, the dealer is no help, says its normal.?? what is the easy answer is what I ask to deal with this same dilution issue.

How are you measuring fuel in the oil? The eye viscometer isn’t the most accurate.

Disregard that video which is as technically useless as it gets.

Or perhaps you already know this.

As @kschachn says, disregard the video, but yes, fuel in the oil reduces the AW performance of the lubricant, as you would expect, so it would increase wear. By how much, will depend on the formulation of the lubricant and the volume of fuel, so you'd really have to do some testing to figure that out. Dave and I discussed running this testing, but I know he's been busy and hasn't had time to make that a reality as of yet.

You avoid it by owning vehicles that don't fuel dilute, lol. Seriously though, some applications are just inherent diluters, while others, if you ensure they get up to operating temperature regularly, won't have any meaningful fuel in the oil, like my two HEMI's (which are also port injected, which helps considerably).

just going by smell (rather strong gas oder) , Yea I know it's not very scientific, but it is what it is, probably will send in a uoa to Polaris and see more accurately, most of the u-tube video's on engine oils are useless ,very few worth my interest, or reasonably accurate. Subarus are known for fuel dilution problems. I drive it rather gently and light on the acceleration. The dealer said I voided my warranty by using 5w-30 PUP, that of course started a argument, it seems most service managers don't know virtually anything about engine oil,all they push is what they sell as they claim it will save the day.

If you remember you pointed out to me that my van was having fuel but Blackstone was not showing it. So I switched to oil analyzers and I'm sending them a sample in a week. I drive a lot man but I don't know I still end up with fuel.

I'm doing 80 mph right now on a steep Highway

 

[Sienna dude]

This stupid foour banger runs pretty cool, if I plug in my scanner now oil temperature will show like 170°. In City driving it drops to 150°

But gasoline is a good solvent, right. So it might clean up the deposits, let's be positive

Not the correct type of solvent and not enough to remove deposits.

There is nothing good about fuel in oil. HPL has posted a couple of good posts on this.

Just go with valvoline advanced 0w16

 

[Sienna dude]

Very very thin, the thinnest 0w16 that I know. Fuel will kill it. In virgin form it is like Mobil 1 0w16 with 2% fuel and 5000 miles.

So, now that you are enlightened, do you appreciate how the statement makes no sense?

Nope.

HTHS is the condition(s) the lubricant is in. Viscosity @ HTHS is the fluid property being measured. You're just using "HTHS" as a moniker for "HTHS viscosity", which has caused some confusion here. Obviously a lube 'experiencing' a property doesn't affect the conditions it's in...it's the other way around.

If you couldn't pick up this simple grammatical nuance after 17+ years and 60k posts on this forum, you need to hit the books.

come at us with this bizarre combative attitude

Nice job projecting. You literally wrote two paragraphs whining about new members.

As a side note, I've been lurking this forum much longer than LSJr has even posted and wish that he would be more in-depth. Am honestly surprised his videos are as popular as they are and that BITOG hasn't nuked mentions of him off the site (yet).
