Long Term 5w-30 use in Honda 1.5t

So you contend that cheap and "generally favorable" spectrographic analyses prove that fuel isn't hurting the engine.

How about you post evidence that the 1.5T engines, in a broad sense, are being damaged by oil dilution. Looking forward to your answer...

Don’t hold your breath, dude can’t even comprehend what I told him on page 1

Fun anecdote that may not mean much but as it pertains to the thermal efficiency of these engines we had a really cold morning yesterday, 2f at the start and 8f at the end of my hour drive. The hood was completely frozen even at the end of the drive, I’m used to some of the ice or snow melting from the radiant heat of the engine but either it gives off too little wasted heat or the little piece of $3 fuzzy cardboard under the hood is really holding back the temps. Also took about 15 mins to get the water temp to the full 4 bars.

No issues with the oil though, no odd noises on startup.

Do you have evidence that fuel dilution is not damaging engines?
The general consensus in the automotive industry is that fuel dilution above 4% is damaging to the engine. Did Honda invent something that is not impacted by high fuel dilution? Any evidence besides the usual statement: "plenty of these cars with high miles..."
 
Back to the typical cycle of “you prove me wrong” , “no, YOU prove ME wrong”. Meanwhile nobody on either side has any data except general consensus of pretendgineers aka BITOGers

Its been proven before that high fuel dilution will increase engine wear, not just by BITOG, its accepted as a fact in the automotive industry. There is plenty of information about this topic outside BITOG.
 
High is not a number
There is a number, 4% or more

As noted, a cheap spectrographic analysis isn't "proof" that fuel dilution is benign. This of course is the hook that certain posters hang their hat on, for what reason I'm not sure. To prove that thin oils are better somehow? Just to be contrarian? Perhaps.

There is no doubt that as the HT/HS decreases the wear increases. If you dispute this then you're out of touch with basic physics. Live there if you wish pickly et. al. but truth is truth.

And as been discussed here and supported by blender HPL, fuel dilution is detrimental to the oil is other ways. It degrades the VII which leads to deposit formation including ring sticking.

All of this makes sense as gasoline is not a lubricant. Given the shorter chain hydrocarbon it is much more of an active solvent than a lubricant. If you want to make the case that there aren't piles of failed engines on the side of the road due to fuel dilution issues then fine, make that argument. But to say it is benign isn't coincident with reality. Trying to make this claim on the back of a $30 UOA is an argument that misses the mark.

Back when you were telling us about "potent fuel"? And when you couldn't comprehend how engines operate in regards to an oil with a somewhat higher HT/HS?

Back then?
 
How does color coding from Oil Analyzers prove engine wear? Have they done some testing to come up with the thresholds for what’s high and what isn’t? I assume they’ve tested and torn down lots of engines and didn’t just willy nilly decide “5% red bad”, right?

I dont feel like arguing that fuel dilution above 4% is abnormal and will cause wear. There is a lot of information about this topic which is settled. Do a google search and compare answers from different reputable sources about percentages of normal and what is not normal.
If you feel like 5% fuel dilution is still normal and will not cause wear, think what you please.
 
Interesting how everyone here wants to argue until it’s time to back up their argument, then you should just google it.
The reasons were provided if you just read what other stated, nobody will waste their time convincing you in already established facts. Its not a grey area. People can argue which oil is better, thats a grey area, fuel dilution is not.
Maybe also ask if oils need additive pacl, need evidence…
 
For those concerned with fuel dilution damaging their engine, it's simple enough to run a thicker oil as a hedge. As mentioned previously, Honda sanctions use of 5W-30 in the 1.5T for many markets. Also, put your car on a more frequent oil change schedule, like 6 months. I'm doing 6 months, and fuel dilution damaging my engine is way down the list of concerns in my world.

As I said, wear metal analysis in used oil samples are generally good with the 1.5T. Bash the testing if you want, I agree that it's not definitive, but it's better evidence than comments like "general consensus in the automotive industry...".

I will go with expert and engineer opinions why excessive fuel dilution is bad (that goes beyond BITOG), not UOA reports posted here. The exact reasons were provided in some of the responses here, but people chose to ignore them. Thats fine.

Hum. I'm an engineer. And I worked for an OEM Japanese auto maker for 21 years. As I said, change the oil more often, and use thicker oil, and stop worrying so much. BTW, do you have a Honda 1.5T?

Honda 2.0T, a bit less of a fuel diluter.

That's obvious, but what about fuel dilution above 4-5%, what do automotive/lubrication engineers have to say about it, normal? or its not in your domain of expertise?
