We had a 18 CRV with the same engine. Wasn’t till the 20K Mark I noticed oil rising. About 1.5 qrts of fuel was dumped into the case. There was no noises or oil pressure problems. I used Amsoil SS 0W20 and followed the olm. The wife wanted something bigger so she got a 19 Pilot.

I'm not trying to beatcha up but I have to ask why 7-8k OCI when you have a concerns with a TGDI? Is it based off UOA's? I don't own a TGDI but if I did I would be looking at 5k with whatever synthetic and a good filter and some UOA's here and there. New engine off the lot would b a 1k and a 3k and then a 5k OCI. Just me.
Doesnt Higher PAO oil on GDI makes the oil degrade faster or make fuel dilution worse? Recalled seeing it on a thread about this.
The base stock composition is irrelevant to any fuel dilution. And what kind of “degradation” are you referring to? Please post a link to the thread you saw.
I may have used the wrong term. But, You participate on this oil forum a lot. I know you have seen the thread regarding this.
It was also a question, not a statement. Read it again.

If I saw it I guess I forgot.
But you referenced it, not me. Why do I need to read it again and why are you so snarky? I just wanted to see how the PAO base stock was degrading since I've never seen that before AFAIK.
Because of the way you responded... People here know you are conceited.
Always looking for errors.
All I wanted was to see the thread you mentioned where PAO degraded due to fuel.
I'm conceited? Better check your own response, painfx.
All our late model Hondas run 10W30 oil in the US and EU
OP,
Do you happen to know what was changed with the 2020 model to prevent/reduce fuel dilution...seems like GDI + Turbo = fuel dilution?
Thanks,

I have no problem doing any maintenance. As a matter of fact I enjoy it and even have a lift in my personal garage
From my understanding it is in the programing for the fuel injectors, something so the car comes up to temperature quicker, and something to do with the climate control system (not sure why). People with the 17-18 are claiming that they must have done more stuff because they had their cars updated to the new programming and still have the issues. Honda has never admitted they have an issue because not all cars suffer from it. So they might have changed something in the 19-20 under the radar and are not saying anything about it because you really do not see 19's with it and I have seen no one mention it on 20's on the CR-V owners forums or FB pages. That is why I was asking about thicker oil (cuts down on OD) and I also change oil every 4K miles regardless of what the MM says. You are always going to have OD on GDI motors but the 1.5 was over the top with literally filling the crankcase with fuel
My son has SI. With 1.5. He says premium gets better performance, gas mileage and keeps gas out of the oil.
I bought a 2016 CR-V with the 2.4 L normally aspirated engine with 19,877 miles on it back in February because I needed a vehicle and it does not have a turbo, and also it is not known for the fuel dilution problem. Even so I do detect a faint smell of gasoline from the oil on the dip-stick so because mine is direct injection I was a little concerned about fuel getting into the oil. So I checked the oil level often and watched for it rising. The dip-stick on mine has a small sharp V bent into it a little above the two holes in the bottom. I would clean the inside of that V and look for oil in it after inserting and removing it. But after a while I found something better.
On mine (and probably on yours) there are two small O rings in the top of the dip-stick. You can wipe the dip stick so the holes on the bottom do not have any oil in them, and then insert the dip-stick until the first O ring touches the top of the tube but no further, and then remove it and see if the top hole does not have oil in it. Of course you always have the vehicle on level ground when you check the oil level.
If you know that the oil is below that mark when you insert only to the first O ring with a fresh fill of oil, (there is no oil in the top hole) you can use that as your gauge to check that the level is not rising from fuel getting into the oil from then on.
You could try inserting up to the second O ring but that is too far for mine and the top hole will have oil in it if I put the dip-stick in the tube that far, also with the resistance of the first O ring it is difficult to slowly insert the dip-stick only enough to get to only the second O ring and not go past it.
I use the inserting to the first O ring and the top hole not having oil in it as my go - no go indicator that the oil level is not rising.

BTW, yesterdays there was a post that mentioned that Bernardi auto parts is a very good place to order original Honda parts and fluids from at a low price.
Check out my post yesterday under "getting new RDX" and the info about carrying a torque wrench to tighten the wheel lugs if you ever have to change to the spare tire.
Today a added an index card with the same message on both sides, to my spare tire changing tools that reminds me to "turn off the traction control when the spare tire is in use." and torque the lug-nuts to 80 Lb/Ft
The turning off the traction control is mentioned on one of the YouTube videos on how to change a tire on a Honda CR-V.
Good luck with your new ride.

I use to fly remote control model airplanes very often. And sometimes people who had a background with full scale (real) aircraft would comment on some things they had experienced. Sometimes those comments were related to military aircraft. One day an elder gentleman commented that during WWII in the arctic he maintained military aircraft and that they would thin the oil in the aircraft engines for cold operation by adding gasoline to the oil. From what he said, it worked and they did not have problems because of it. Though I do think those engines had a system that added more oil to the engine in flight to make up for loss, so after the engine was warm the additional oil may have been non-diluted oil. I did not think to ask him about that part of it.
I'm just passing along this example that some dilution of gasoline in the oil does not necessarily mean the engine is going to be damaged.

That engine in that model is known for fuel dilution.
The wife has a 2018 Civic with the 1.5T.
From what I understand, fuel dilution is most likely to occur when the vehicle sees mostly short trips, and, especially, when those short trips occur in cold weather (ECU specifies a rich mixture for starting in cold temps).
Colder ambient means the oil takes longer to reach full operating temp, at which fuel evaporates.
Most people agree that this becomes a non-issue when the owner is careful to frequently take the car out for longer drives and allow the oil to reach full operating temperature, allowing the fuel, along with any moisture, to cook off.
My wife and I do this with hers, and haven’t had any rise in oil level or any other problems in the almost 2 years and almost 40,000 miles that she’s had it.
As for oil, just use a full synthetic from one of the top brands, and you’ll be fine. I stocked up on 0W-20 Valvoline Modern Engine and Mobil 1 Annual Protection last fall when Auto Zone had those on clearlance for $2/qt. I have enough for at least a couple of years.
But, right now, I actually have Pennzoil Platinum 10W-30 in it, along with 1 quart of Edge 0W-20 that I had lying around. I can’t tell a difference in how it runs from straight 0W-20.
It‘s not picky.
If I had to buy oil at full price, I’d probably just run a Good, full-synth 10W-30. I like the protection of a 30W, and I like the fact that 10W-30 usually has a nice, low Noack rating, and not a lot of VM/VII.

I also have a 2018 1.5L Honda CR-V and first I worried about the oil dilution, but then I found that if you drive your car to the operating temperature, then you don't have to worry about it. I have about 28k miles now, and my oil seems to be in good condition with no "extra oil" during the 5k oil change interval. Used oil comes out with no smell of gas, too. I've been using SuperTech 0w-20 since new until now though.
