Oil for 2018 Honda Civic Lx

[LKJ0404]

Hey everyone, I drive a 2018 Honda civic lx 6-speed manual, and attached is the oil page of the owners manual. My car has about 95k miles, and I put on roughly 1k a month with most of them being highway miles. I'm from Ohio, so summers can get to ~100F a couple days a year, and winters can be below 0F occasionally. My car has had no problems leaking or burning oil in the past. The last few years I've used valvoline high mileage 0w-20 oil, and follow the MM for oil changes. However, I've been told that using a heavier oil like 5w-20 or even 5w30 can help with engine life compared to the thinner 0w-20, and changing every 5k miles instead of 8-10k is noticeably better. Unfortunately, I know very little, and I was wondering if any of you would have an opinion

Thanks!

Any 0w20 or 5w20 will be fine in your Civic

If you're mostly highway miles, that is much easier on oil, and you can use the minder's suggested OCI with no problem.

Is your Civic a turbo?

Oh sorry! It’s a 2.0 L in line 4. No turbo. Thanks!

Those HONDA K20 engines aren’t picky. And the fact that the K20(2.0L) is a non direct injection fuel system(only port FI), plus having a manual transmission to boot, you may have one of the most reliable drivetrains made today.
The HONDA “K series” engines(K20 & K24 pre Earthdreams) are nearly indestructible especially w/6spd man.

GO HONDA !

Thanks, that’s great to hear! Id like to keep it as long as possible. I’ve heard that using a heavier oil (5w-20 or 30) can help engine longevity at the small expense of gas mileage. Do you know if there is any truth to that?
Thanks!

5w20 is actually not a heavier oil than 0w20. Both will be the same viscosity at operating temperature. The only difference is that the 0w20 is much better suited for extreme cold temperatures (way below 0F for instance)

I have a 2016 Civic with the 2.0 and I have always run 0w20 in it and have followed the oil life monitor for most of the oil changes (occasionally I have changed it earlier for various reasons) I have 262,000 km on it and it runs great.

Run what the manual says 0w20 and enjoy a long life with your civic.

Consider changing the manual transmission fluid if you’ve never done so, it’s only around a 2 quart capacity and cheap insurance if you’re keeping the car for the long run.

Amsoil makes a 0w30 signature series that would be a good fit for your car, and you can run more extended oci.

If you closed your eyes and threw a baseball at the oil aisle at your local Walmart and only bought what you hit each time that engine wouldn’t know any difference. It’s a solid runner.

I don’t know of any truth to that.
However, I Don’t believe that you’re gonna hurt anything by going to a 30 grade of oil that’s for sure. And I don’t think you’ll see a Significant keywords significant difference in fuel economy. Maybe use a 30 grade in the summer in a 20 grade in the winter. Good maintenance is the key to longevity. Not only oil changes but taking care of all the fluids from front to back and maintaining the vehicle in general and keeping it clean and free of salt. Along with making repairs as they occur instead of letting them build up… fix things as they break, don’t wait.

whatever oil you choose, 0-20, or 5-30...change it and filter 5000-7500 miles...stick with known oils, Mobil 1 would be fine, or Castrol or Valvoline

I changed the manual transmission fluid in my old Accord at around 80,000 miles, and the clutch never felt the same again. I sold it because of that. However they did it, the clutch got spongy. Maybe there was air in there or something. Was sad because that was the end of an era for me - went to an automatic after that.

That would likely be from getting air in the hydraulic clutch line or screwing with the adjustment, not the fluid in the gear box.

Thanks. I should have taken it back to the dealer. But was time anyway I guess to get an automatic.

This is true.
This is what happans when your drive more than 5,000 miles with Walmart oil:

If that were my Civic I would buy a bunch of Mobil 1 0w20 and service it 4500 to 5K miles. For extra credit, get a MityVac and swap the filter every 2nd service.

You didn't do it yourself? You didn't consider taking it back to the place that did it?? The fluid in the gearbox really shouldn't affect the clutch at all.

Could have taken it back and they would say nothing is wrong, or would "fix" it and it would not really fix it, etc. It didn't feel the same, so I sold it and moved on. Resale was good for a stick, and the new car was cheap at the time.
