Car calls for 0w20 on cap and am eager to try 0w16. Any harm in switching?

I’d be worried to use such a thin oil in that engine, we had the same car.

Why chance it unless it's been approved for your model and year by Honda?

I dug up this UOA, and I see where you once made a post about wanting to try a long OCI, seems like the engine sheared 5w20 Mobil 1 EP pretty good after only 9000mi, I don't think I'd stick a 0w16 that starts out about that thin in the engine myself. https://www.bobistheoilguy.com/foru...1/m1-5w20-ep-honda-civic-r18z1-9137k-oci,

Why would you be eager to try the 0W-16?

Unless Toyota has back specified it for that engine, I wouldn't.

Apply a "worst regret" analysis. Not using 0W-16 means you give up a small (potential) saving in fuel, but by using 0W-16 you risk major engine repairs. So which would be regret more? I know which one I would.

I have had 3 Civics, most recently a 2013 with 1.8L.
Yes, 0W-20 on the cap.

My experience with 2 data points:

-> I used M1-EP 5W-20 year-round here in TN, since that’s what my Accord uses (I know this is not a good reason).
Civic 1.8L started immediately and ran peppy and no noise even in the coldest weather, sitting outside.

-> Interestingly and puzzling, this was not the case with M1-EP 5W-30 in cold weather. Slower cranking, a bit of shaking, and lacked pep for the first 2 minutes, only in cold weather.
Several OCI with this experience.

All of the above was oil I purchased & changed myself.


My suggestion for you is to at least continue 0W-20 through the summer.

If you change to 0W-16, I hope you will stay with the same brand & type, then watch for normal stuff - oil consumption, leaks, noise, change in starting, cold pep, etc.
Then be sure to share your experience here!

Why would you use it in an engine not designed for it??? I can't imagine any measurable gain in mileage, and there's no price difference.

Just use whatever the manufacturer recommends... Done.

Has Honda back-specified 0W16 for this range of engines and Model Years?

If not, Absolutely do not use it.

I would add that there would be nothing to be gained and much to loose.

0W16 is in the 20 grade range for KV100 but below range for MIN HTHS.

If you want to try a "thin 0W20" that is NEAR a 0w16 try Subaru Genuine (Idemitsu) 0W20 or

The MOTUL that I am running in my VW which is MOTUL VW 508 00/ 509 00

BTW pretty quickly, I had found the MOTULto be too thin for my use, the engine was burning it at a good clip,

so I Added Mobil 1 0W40 FS ( MB 229.5x, Porsche A40 ) to a sump that was down a 1/2 qt and the engine responded marvelously.

SO let the "thinnies" beware smile

We had a 2012 Civic 1.8L. Always used M1 AFE 0W-20 @ 10K OCI. No issues at all.

I have some Vermont family members who are Subaru owners (yes, I'm sarcastically picking on them) who drive 10 under the speed limit at all times. They also believe that any perceptible acceleration is an affront to creation itself. I don't think I've ever seen the tachometer exceed 2000 RPM when riding with them.

The engines in these cars are so lightly loaded, that 0W-Water motor oil, WD-40 or Wesson vegetable oil, is just fine for their needs and they will never experience any lubricity related operational problems.

The rest of us operate in the real world and recognize that motor oil must perform a number of seemingly different tasks. From flowing very well when below ice cold, to providing adequate hydrodynamic connecting rod lubrication near redline and ring to cylinder lubrication during spirited hot summertime driving. All while keeping the pins and links on timing chains from excessive wear rates.

Test after test show that adequate viscosity is the driving factor behind lubrication. Additives can help, but it's viscosity that does the heavy lifting. Ultra low viscosity oils have but one goal, better economy. Engines must be designed for low viscosity oils. My attempt at improving high RPM HP by using 0W-20 in a Miata resulted in a 255 PPM Pb UOA and destroyed rod bearings. Yes, I was racing it, and yes I was looking for any advantage over my competitors. But the bottom line was insufficient viscosity resulted in failure.

Gas turbine engines use roller and ball bearings, that work perfectly with low viscosity synthetic ester oils. Piston engines have piston rings scraping down the cylinder walls, often have camshaft components that don't have rollers, sleeve bearings on the crankshaft and camshafts, timing chains made from pins and sheet metal links (fact, chains last longest with 30 viscosity oil) and the only thing keeping those parts "apart" is the oil's viscosity.

What are you looking to gain .00000001 mpg? Took me years to accept 0w20 now 0w16 wow that's like lily white sewing machine oil.

Yes yes use it always fun to experiment with oil viscosity. Let us know how it worked out.
