Does anyone run 5w30 in new Honda?

[RyanY]

I typically use 0W20 in my Honda if I can find it on sale/rebate. Otherwise it gets 5W20 or 5W30 that was discounted, but usually this is mixed with the 0W20 that was left in the jug(s) from previous OCs. I really haven't noticed any difference among grades so far, and I don't expect to ever notice any measurable differences. Ditto for my Cad (spec 5W30) which typically uses about 1 qt between OCs. I usually top it off with leftover 0W20 or 5W20

Just like the title states, does anyone run 5w30 in their new Honda?

Nope. Use the factory spec which is, contrary to another poster, a requirement, not merely a recommendation or suggestion. If you’re under warranty (or not) and have an engine issue, how much would you like to bet Honda won’t do an oil sample and do labs on viscosity? And, if that oil is out of spec, how much would you like to bet your warranty or “good will” is void?

If it were a warranty requirement it would say so, something along the line of "Use of any oil grade other than 0W-20 will void the Honda new car warranty". But it does not. Often they do say that if you do use a different grade and it causes harm then that would violate the warranty, which makes sense. Using a grade lower than recommended may indeed cause harm but a higher grade will not.

One thing that's never answered in this discussion is why an automaker would void a warranty for using a higher grade. For what reason would they do so? Warranties are voided for harm to the vehicle by owner action. For what reason would Honda or another manufacturer void the warranty for using a 30-grade? They won't, and can't since no one will harm their vehicle by doing so. It's become some sort of fear mongering to advocate that they will.

On my Tiguan when it had free dealer oil changes I asked if they would use 504 00 oil instead of 508 00 and they didn't even blink when saying yes. Oil grade is only a warranty issue when it harms the engine and again, no engine will be harmed by a higher grade oil. Higher grades protect better, not worse.

If anyone can explain in technical terms why using a higher grade oil opposes Honda's interest, I'm all ears.

Why is their capacity so low?

To allow for the .5 quarts of fuel being pushed past the rings - thanks to DI.

Nobody can, not even an expert tribologist from Honda could prove that 5W-30 is harmful to the engine, and xW-20 is not. He would instead say the 5W-30 provides more film thickness (MOFT) between moving parts, and therefore more wear protection.

I'm still waiting for the proof from anyone that cleaner oil does not result in less wear, lol.

0w20 in my 21 Pilot. 5w20 in the summer is tempting though.

Why? both are readily available and essentially same

 

[Revving2Redline]

If it's stated that running 0w20 is the optimum grade then if it shears down or has a fuel dilution issue and isn't a 0w20 anymore is it still optimal? I can only assume that a 0w30 or 5w30 will eventually become a 20wt over time making it the optimal weight. I believe I saw Pablo running 0w30 in his vehicles spec for 0w20 and wasn't losing any sleep. With a trash tune on 87 octane and fuel dilution being noted as high on these vehicles, I don't know why you wouldn't want a bit more piece of mind. At operating temperature, they are fairly close. I do admire how at least the Civic Type R gets almost 7 qts which in my opinion all these cars should have if they are gonna run direct injection with boost levels in the 10-25lbs.

We had a long thread on this subject a while back, and as your post shows above there is no statement that declares the oil grade is a condition of the new-car warranty. An oil that causes harm will violate the warranty, therefore using a grade that is lower than the one listed could indeed be an issue. But no higher grade is going to cause harm.

People are really misinformed on this and lots of misplaced fear surrounds the topic. One wonders if that's the ultimate intent of the wording that a CAFE award letter requires of the automaker. If so then they have succeeded.

They'd have to prove it was the oil. I'd bet if the engine was full of clean oil and not sludge they wouldn't care.

... Can't hide the truth.

PS - lot's if people don't like "acceptable" wear, they want better film thickness headroom.

I want the least wear possible. If you intend on keeping your car as long as possible it will make a difference above 150k when you're not burning oil and your engine doesn't sound like a dryer full of gravel on startup.

I have to look into more why these oils are the same, newish to BITOG. I just get my oil and filters from Honda.

 

[Schandyman]

Before 0w20 was formulated and found fit for highway use, I wonder how many miles and hours went into that study? Anyone know?.. I don't know. Its not a new Doritos flavor or ice cream to boost sales.

 

[JavierH19]

Yes Ive ran 5 and 10w-30 in the 2015 civic.

 

[himemsys]

If you want to stay in grade, but thicken up the oil to the top of the 20 grade requirement ( 1.0 would work well as both devide evenly into 5, so you could use 5qt jugs without worrying about odd amounts of leftover.

 

[kjbock]

I use 0W-30 and 5W-30 in my 2019 Honda Civic 1.5T for the last 20,000 miles or so. Runs great and I get 32-34 mpg with around town driving (same as I did with factory oil). I smell gasoline on the dipstick every once in awhile, but it looks like they fixed the fuel dilution issue by the 2019 model year. Still won't use 0W-20.

That is what I did with a J35Y6 engine in a 2021 Honda Passport that takes 5.7 quarts at refilll. I used 4.7 quarts of M1 0W20 EP and one quart of M1 0W30 ESP. It made me feel like I was some mad scientist that was coming up with the ultimate motor oil concoction! By my calculations the KV100 of this blend would be right under the 9.3cSt threshold.

When worked at the Honda dealership last year I saw a lot of people that had turbo Honda engines with fuel dilution issues. At this point I don't know why you wouldn't use an Xw30 grade oil in a turbo Honda engine.

What oil would you recommend in the Honda turbos and

Do you update the Honda maintenance website when you do self maintenance?

I am a big fan of Mobil 1 ESP 0w30 and Shell Rotella T6 Multi Vehicle 5w30.

Yes I would update my information on the Honda owners website as well as the MyCarfax app.

Awesome, I’ve been video recording my oil changes with, receipts, materials, date and mileage as proof. Hopefully entering info allows past dating, my car fax I’ll look into that. Thank you

Before the switch to 20 wt. was made, the requirement was that the engine had to "last" 200 K miles on 20 wt oil. That specification could not (in theory-I guess)- be met. That requirement was changed to 150K miles. I am "foggy" on the details

 

[teh60]

I would use 0W20 if that’s what is recommended. If you are worried about fuel dilution or severe driving conditions then change it sooner. But I would do that with any oil.

Looking at an sae viscosity chart there are lots of suitable viscosities for the temperature chart.
