Hello all,

I think we already talked about it but I wanted to check if there was any updates.

I checked my oil level last weekend and it was slightly above the end of the orange dipstick and I am 80% sure it was smelling like gas.

My last oil change was in November and I probably drove something like 5000mi since. Oil was fairly dirty actually. I do not have issues with the car otherwise.

So I guess my questions are:

1) Is there any test I can do to confirm that there is indeed gas in the oil?
2) Is there any news about potential oil dilution with that engine?

This has bothered me quite a bit as well, even with turbo or natural aspirated engine, you'll find some oil dilution, Simple reason is that expansion and contraction of the piston rings on cold engine and first start ups. And this is a hybrid, which means that the engine probably will not heat up fully for quite a long time driving. I would say almost an hour. If you have short little drives, you will find more gas in the oil. What I do is put mine in sport mode on short drive to keep the engine running longer and of course in the winter time I always use sport mode to heat the engine faster. It use more gas of course but I will find that will be a lot less problems. I change my own oil, and have noticed the same. It has nothing to do whether it's a turbo or not.

That is an interesting take. I did notice that in cold days, sometimes the engine never heats up past 120 F in city driving.

I personally prefer to warm up the engine gently and progressively as opposed to quickly using sports mode. I am no mechanic though.

Does it taste like there is gas in the oil too?

On a more serious note. I have never noticed. I have an oil change in two weeks, so I guess I can check. As a note, there are no bulletins or anything on oil dilution as of March.

My last oil change was in September and I have currently driven about 4K miles since. I live in the North East (cold winters & short summers) and my normal commute to work is about 10 miles, so not much time for the engine to warm up. I checked the oil this morning and the color looks pretty much identical to yours. I also noticed a slight hint of gas but I literally had to hold the paper towel 1 inch from my nose to be able to smell it. I have never smelled the oil in any of my previous (non-hybrid) cars, so I don't know if this is normal. I will ask the dealer to check this out, at my next oil change, so that there is a record on file in case this becomes a problem/legal issue.

They will tell you that it is normal. The only difference that you don’t have to worry about is dirty valves. People with Direct fuel injection have more gas in oil than natural aspirated engines. I’ve seen both Toyota and Mazda four-cylinder NA engines both have some minor dilution. Remember that some dilution is better than sludge any day.

Blackstone Laboratories <--- They can do an oil analysis for you.

The Insight shouldn't have the oil dilution problem. It uses port fuel injection. You might get minor dilution due to your driving style but you would normally burn it off with a long drive.

I checked my oil level last weekend and it was slightly above the end of the orange dipstick.
Double check if your car is on a totally flat surface. Your car could be on a very slight non-even surface so when you pull the dipstick out the reading is off a little. I wouldn't worry about it if it's slightly above the mark. This engine is the same one in the Honda Clarity and most Clarity owners don't even run the gas engine much for the whole year since they drive exclusively in EV mode.

I was previously concerned about fuel dilution, due solely to frequency of stop-starts.

I can now comfortably state that there is no fuel dilution--nothing to see here.

Why? I have used from the beginning only state of the art 0W8 motor oil. It stays in grade, as in HTHS identical to virgin oil, per sophisticated used oil analysis.

Not involving Gasoline Direct Injection was a major consideration in my purchase of a 2022 Insight.

Oil will almost always smell like fuel. That doesn't mean that there is enough of it in the mixture to be of concern. You won't know unless you have the oil analyzed.

I'm at 34k miles with my 2020. I've had an analysis performed by Blackstone with each oil change. Here are my results.

Blackstone Laboratories recommends <2.0% fuel %.

<0.5% @ 10,771 miles (10,771 interval)
<0.5% @ 21,333 miles (10,562 interval)
0.8% @ 31,572 miles (10,239 interval)

As you can see, the first 2 tests registered lower than the lowest threshold that they report. The 3rd test increased slightly but is still below the threshold of concern.

I plan on running an analysis with each oil change. If any of the results come back with parameters outside of recommended thresholds I'll notify the community for something to monitor.

You're an awesome person for doing this thank you!!!

awesome, what did you use to extract the oil out of the engine?

Thanks for the information!!!
Oil change after 10,000 miles is a lot in my opinion. The oil degrades substantially after about 5,000 miles. Yes, I understand that it all depends on the loads, driving speed, temperature and much more, but my advice is to change it after 5000 miles and the car will say THANKS. )))

I have the oil changed when the maintenance minder gets to 15%. When I had the oil changed the first time, I also had Blackstone Laboratories perform a TBN test to determine the oil condition. It came back in great shape and they recommended taking it to 12,000 if I want.

I used to have a Corvette Z06 that wouldn't alert for an oil change until about 7,500 miles. If a high performance engine can go that long between oil changes, it shouldn't be a problem with the Insight. Especially since the engine isn't even running for the entire time.

"The Maintenance Minder™ system monitors operating conditions such as oil and coolant temperature along with engine speed to determine the proper service intervals. Depending on operating conditions, oil change intervals can be extended to a maximum of 12,000 miles, potentially sparing the owner considerable expense and inconvenience over the life of the vehicle."

12,000 miles matches what Honda expects out of the Honda Insight. The best time to change it is when the maintenance minder system alerts you to do it due to other factors like time and engine operating condition.
