I just got my oil report back today for my 2021 CR-V. After changing it at 3400 miles in November because the oil had risen to the top of the orange piece, the oil rose 10mm in just 900 miles. This was all on regular unleaded. At 4300 I switched to 93 octane. Octane free is not available in my area. The oil level stopped rising after the switch. Now at 6900 I changed the oil again and had it tested. It had 2% percent gas in the oil, which Blackstone said was probably the 10mm rise I had seen. My plan now is to continue using 93 octane and watching the oil. If it doesn't rise more than a few mm, I may extend the oil change mileage to 5000. A few other things I did. I bought an oil dipstick without that orange plastic so I can get an exact reading. I always check it cold in the morning, so I can get an exact comparison. When the oil is warm, it will show a 2mm expansion rise on the dip stick. Again, if I see a 10mm rise when checking it cold, I will figure that I got 2% gas in the oil, and it's time to change it. If it suddenly starts rising fast or goes beyond 10mm in 3500 miles, then I'll know I may have dirty injectors, worn plugs, or some other problem that needs looking into. All this said, I think the 1.5T is a tough little motor. Factotum Life, you got 82K on yours even with all the gas that was in the oil over the years, and it still runs! I have hopes of keeping mine for many years.
82k is not impressive tho. Not everyone is rich or can buy cars new. Heck it's not uncommon to buy a used car with 70-80k miles on it. Older Hondas have gotten hundreds of thousands of miles on them. If I'm buying a new year Honda I expect to at least get a good 150k out of it. I'm looking at a 2019 Honda CR-V with less than 30k miles, and this whole business is putting me off. It would be a major investment for me at around $30k for the touring fully loaded one, but probably will look elsewhere because it's not worth to pay basically a new car price for something that will have major problems after 50k miles of use. Even if I wanted to get a brand new 22 it's the same engine. What a sham.
@@hak2297 I can't speak to 2019s. On my 2021 I'm getting no oil rise AS LONG AS I use premium. My daughter borrowed my CR-V for a couple of weeks and put 87 in it. The oil started rising again. I put 93 in it and it's not rising any more. I use only top tier gas and GF6 oil. I am concerned about oil rising again as the fuel injectors age. To not have to deal with all this, it's half tempting to trade it for 2023 HR-V with a 2.0 port injection (80s technology, 80's reliability, and 80's fuel economy). What's holding me back is the CR-V is a really otherwise nice car.
New viewer of your Adventure in Oil Dilution/High Octane Fuel... Got Fuel Dilution of my own with a GMC Terrain (2.4L Ecotec AWD)... Had/Have been taking measures (including E0 91 Octane, which conveniently is, for the moment only 20 cents or so more then regular E10/87 octane... Requires an extra 20 mile round trip to get but... Helpful for improving the oil warm-up/fuel burn off... Due for a 3 month/almost 3K mile sample soon (picked up a Dipstick Sample Pump so I can more easily test the oil without, hopefully, needing to dump oil if its still got some useable life left...)
Thanks for video and new raport. When you take intake manifold off please check the intake valve for carbon-deposits and upload some pictures please. As you probably know this is a common problem in engines with direct injection. It could be very interesting to see how they looks like after 80k miles. Thanks again and can't wait for next video.
Thanks for your video! Looking forward to seeing the injector video. Could worn spark plugs also contribute to the fuel/air mix not firing completely and so add to the delusion problem? My suspicion is that EVERYTHING on this engine needs to be working top notch or the gas in the oil will creep up.
Thank you for sharing your findings on the 1.5T throughout your recent videos. Have you seen that changing the injectors has helped at all? I notice this video has been out for 9 months so I’m curious if there’s anything new you might have to share.
Replacing the injectors helped some with the oil dilution. I am waiting for oil sample results from a recent oil change. I will post a video once the results arrive. The oil rise was about .5" running 87 octane on a oil service 10/8/22 to 2/18/23.
@@factotumlife Thank you so much for your input. I really appreciate it. The fact that you owe people like me nothing while still putting the effort into sharing your findings on these videos is huge. Seriously, thank you. I look forward to watching your new video and I also look forward to swapping my injectors with your video as reference.
my 2022 not leaking by gas yet at 8k. another owner was mixing 0w20 oil with5w20. thinking about going entirely to 5w20 oil. this a dagum shame in 35000$ car!
Honda's days of problem free engines are long gone when they started with these small lawn mower engines and turbo them up . Same with all the other manufactures. Governments EPA's are to blame.
The EPA demanding our vehicles get better gas mileage is not a bad thing. The issue is how the car manufactures are going about trying to reach those goals. Small engine with a turbo charger then adding in the low friction rings is the main issue. The rings do not offer as good a seal at low temps. Once the engine is reached normal operating temps they seal better but with the Turbo throwing high pressure air into the combustion chamber makes it hard to keep that fuel out of the crank case. Getting rid of the low friction rings and going back to normal rings would help alot at providing a better seal. Bottom line They need to find better ways to save fuel for us drivers

Dear sir, your observations are more valuable than the Dealer's help ;)

Are you doing short trip? Drive it for an hour highway speeds and burn off the fuel in the oil

How is oil weight going to make any difference when it's fuel seeping past the rings? I also can't see how higher octane gas will help, either.
