I run on motul 0w30 nergy. I chose it on my first oil change. So far so good. I expect higher change intervals. The first one with the factory oil was @ 6500 km!!! Based on what the car said with the service tool.
One good thing is that i don't hear the same metalic sound @ higher revs as before
I would never go with 0w20 again. In Romania, Honda made modifications on the 2018 car manuals and introduced 5w30 as recommended oil viscosity!!!
I'll stay with 0w30 just because my car has no exposure to low temperatures.
Not that it matters, the difference is very small, but the 0w-30 is supposed to be slightly better in very cold temperatures.

I know this an older thread, but I thought I would weigh in. I have a 2018 Honda Civic Si that I bought in June 2018. I have really beaten the crap out of this car since I bought it, driving it several times between Northern California and Southern California (I live in the USA). If anyone knows the highways between Northern Cal and SoCal, you would know that it is 350 Miles of harsh roads with harsh climates, in the summertime the weather can be between 100 and 115 degrees F. I did notice that with the 0W-20 factory fill, taking the car to higher RPM's (above 3500) was slightly nerve racking. Also the car can be a little jerky when staying in lower gears.

When I hit 5000 miles, I decided to change the oil for 0W-30 full synthetic. Every since, I can now take the car in much higher RPM's and it feels smooth, and is definitely quieter. I'm going to stick with 0W-30, I feel that this is the best oil for hard driving and better performance

I have an update to my last post. This Thursday I drove to Southern California on the 0W30 synthetic, and on the gas mileage front, I actually did better than my last trip. On my last trip I averaged about 38.9 mpg, doing roughly 80 mph. On this trip I averaged 40.9 mpg doing the same speed. The only difference was the ambient temps, on my last trip the outside temps were between 90 and 104 F, this trip the outside temps were between 65 and 84 F. Anyway, gas mileage has pretty much stayed the same, but I have definitely experienced more smoothness while being in the higher RPM ranges

I'm also planning to stay on 0w30 Motul in the future

I'm guessing that those who are leasing are more inclined to go with 0w20 and 10k mile oil changes since they don't really much care about the car they plan on giving back to the dealer after 36 months. Those who are buying their car(like me) might be more inclined to shorter change intervals and 0w30 synthetic. I leased once, about twenty years ago,and my experience was I had no interest in the car at all. Rarely got it washed, never waxed it even once,(why would I want to wax the dealers car?) and couldn't wait for the lease to end so that I could unload it and then buy a new car that I actually cared about. I'll never lease again IMO it's a lose-lose. Arguments about a lease avoiding the depreciation in the cars value are double talk and don't make sense logically. I bought a 50 inch HD panasonic plasma TV (the last plasma on the market) and paid about 700 for it eight years ago. It's value depreciated just like a new car. What does that have to do with anything? I love this TV. Wouldn't sell it even if someone offered me 700 for it today. There's nothing like a plasma picture. And the other argument about your investments making more money than funds spent buying a new car is equally nonsensical. A car is a possession like a flat screen TV. Comparisons with your stock market investments are illogical.
sorry for the off-topic rant. it's early in the morning and I'm bored.

Just because you lease a vehicle doesn't mean you don't take care of it as well. You do have the option to buy it later. It's hard to go wrong with a 0% lease. It allows you to decide if you want to keep it in the end or got stuck with a mistake and can't wait to get rid of it. I leased mine and do my own oil changes at around 50% life. I see no reason not to buy it out as it has been an excellent vehicle thus far. I wouldn't have saved anything by financing it.

I do however completely agree with the Plasma tv. I own 3 of them incl Panny and love them all.

OK I think I will run 0w-30 on my next oil change. There are a lot of biased facts here but really no scientific evidence...sorta. I own my car, not lease it and I am in love with it. I just changed my oil a couple of months ago with Castrol Edge 0w-20 and Bosch 3323 oil filter. The car feels smoother, but maybe its just the placebo effect. The only thing I am afraid by running 0w-30 is if it can't reach oil fast enough as 0w-20, but then again the engine will get warmer faster on the cold winter mornings because the oil is moving slower...right? Also, I am afraid of fuel economy loss but I see it barely makes a difference.

Correct me if I'm wrong, or should I stick with Castrol 0w-20?

You should learn some hydraulic fluids dynamics first, some basics. Once you do that, suggestions you've just made will not made again.

But to answer your question, just keep whatever you have in there right now and forget about it.

Well then maybe anyone who is making an oil thread should go to their local community college to take hydraulics fluid dynamics 101 before posting it.
What is up with people on this forum that act like they know everything??

Calm down, good fella. I'm neither making these treads nor supporting them. Although occasionally I'm trying to prevent them from getting flooded with nonsense (my mechanical engineering degree allows me to do so, not the degree itself obviously but the knowledge I have).

Once again, to answer your question, keep using 0w20 Castrol Edge - good oil at decent price, car will be happy

Pour yourself a drink and enjoy the night

Cheers

Will be taking thermal fluid science next semester haha. Maybe I will come back after taking that class...:yes:

Get ready for some real deal crappy science. Hydraulics was my least favorite science and it still is. And most definitely enjoy college/university days. Back in my days I could barely afford a pack of cigarettes not speaking of Honda Civic. Lucky you. Haha

Not too much of a difference in reaching operating oil temp between the 2, if thats what you’re afraid of.

The Society of Automotive Engineers (SAE) has developed several viscosity classifications or grades, such as 5W-30, 10W-40 and 15W-50.

These viscosity grades designate the specific ranges in which the particular oil falls. The “W” indicates it is suitable for use in cold temperatures. (Think of the “W” as meaning “Winter.”) The classifications increase numerically; the lower the number, the lower the temperature at which the oil can be used for safe and effective engine protection. Higher numbers reflect better protection for high-heat and high-load situations.

The overwhelming majority of oils today are multi-viscosity, meaning they behave differently at different operating temperatures to provide the best of both worlds – good cold-flow when the temperature drops and reliable protection once the engine reaches operating temperature. For example, a 5W-30 motor oil performs like an SAE 5W at 40ºC and an SAE 30 motor oil at 100ºC

From the amsoil website https://blog.amsoil.com/a-beginners-guide-to-motor-oil/#what-does-sae-stand-for-in-oil

You can youtube engine oil temps for more info.

10/19/17 sample was the old Amsoil SS 0w30
2/21/18 sample was the much vaunted QSUD 0w20
5/4/18 sample was "new" Amsoil SS 0w20
8/7/18 sample was "new" Amsoil SS 5w30
1/11/19 sample was "new" Amsoil SS 0w30
Seems this engine (1.5T) likes the new SS 0w30. I'll run it again, and check in 5k miles just to make sure it's not a fluke. No change in driving style (I drive like an a-hole), but I never run this engine hard before it warms up. Looks like I should get the fuel dilution tsb done. FWIW, this car had 2 break in oil changes before I ran the old SS 0w30. I think I'll run the new SS 0w30 in the CTR as well.
Cheers.
