Is there oil dilution issue or other issues with accord 1.5t engine?
Reading from the forum and the web, the 2.0T seems like a much better engine than 1.5T.
Of course I want to get the 2.0T manual, but it's out of my budget and the MPG is also worse.
 
The 1.5T would be fine paired with the 6 speed and a lot of fun to drive. I personally didn't care for the 1.5 with the CVT and opted for the 2.0 (wife needed an automatic).
 
If it's out of your budget, and the fuel economy concerns you (again money concern), why are you even debating the two of them? You can afford only one lol.
This is exactly how people end up in debt.

Well, sorry, not really out of budget, I just don't want to spend that much money. I haven't driven manual car for a while and just want to have fun a little bit. My concern is I have seen a lot of issues with 1.5T engine in the CR-V forum.

Also, searching the internet, the MPG for 2.0T is all over the place from sub 20 to high 20's to low 30's. Under normal driving condition, what is the realistic MPG for the 2.0T?

Well played, sir. Well played.....

Is there oil dilution issue or other issues with accord 1.5t engine?
Yes, there is an oil dilution "issue" with the 1.5T in the 10th Gen Accord. It has resulted in zero failures. There is one big thread on the subject that you can find by searching for "1.5T oil dilution".

This 1.5T vs. 2.0T is debated to death:

Very soon in this thread, people will accuse you of being cheap, a woman, a street racer, a lazy driver, a real man, etc...as the epic debate rages on. Then someone with a cool head will drop in and just tell you to drive each and decide for yourself.
 
Have you tried driving them both? Aside from power, I believe they each have different transmissions. I am a long-time Honda manual driver and I hated the 2.0T 6MT. I'm not saying it's terrible or that I wouldn't have gotten used to it if I bought it, but on a 15 minute test drive, the high engagement point made it feel a lot like work. I've read on here (and have no idea if it's true) that the 1.5T 6MT uses a unit more similar to the Civic Si and it's a lot more like typical Honda manual transmissions.

If I were on the fence, this would be a big determining factor. Personally, I ended up with a 2.0T 10AT Touring, with the 2.0T Sport 6MT knocked off my list after that 15 minute test drive.

strange?, I have been driving all Accords since 79 and see no difference, just gets better, also my last 2014 Sport was 6MT, I am very pleased with my 2019 Sport 2.0 6MT, no issue, I never considered 1.5 6MT
 
I drove both with manual transmissions, and ended up opting for the 2.0. That being said, the 1.5 was no slouch. The transmissions in both vehicles felt the same to me. Like others have said, test drive them both and then decide if the 1.5 is adequate or if you really need the 2.0 to be happy..... Good luck!
 
The 6-speed in my 9thgen V6 is nothing at all like the sweet 6-speed they put in my 9thgen Si. I assume it had to be that way to cope with the higher level of torque the V6 puts out. Since the 2.0T puts out even more torque, I wonder if it's built similarly or feels similarly different to the one in the 1.5T. Of course, I should probably just go test them to find out the answer for myself.
 
There is but one guarantee; if you get the 1.5T, you'll wonder for the life of car if you should have gotten the 2.0T.
I sometimes wonder if I should have opted for the MT, but not the 2.0. Go figure.
 
I have 6500 miles on my 2.0 manual and am averaging 29 MPG. I bring it to redline just about whenever it is safe to do so and cruise at 75 on the highway.

I also test drove the 1.5 and really enjoyed it. I went for the 2.0 because it's faster ? and came with options that I valued.
 
OK, stop being a cheap, lazy woman. Rick, did I get that right? (I miss your wit.)

Hondafan2, I think most of us understand financial constraints. The 2.0T is the better Accord and is particularly rewarding when mated to the 6MT. But if you are on a budget, why not consider a Civic? Hold on, I think I feel a Rick quote coming, something about test driving…...ahh........, I lost it. It’s gone. Seriously, Civics drive amazingly well, especially the Si. The Si has great seats too.

As for fuel diluting the oil, I see that as a good thing. First, it makes the oil thinner for better fuel economy. That saves you money. And second, the gas acts as solvent to ensure no gunk ever develops in the oil system. Who doesn’t love the idea of a clean, sludge-free oil system? 150,000 miles from now you can brag about that to your friends at parties. Just think of fuel in the oil like Seafoam in your gas tank.

Seriously, fuel in the oil results from blow-by, something 100% of turbo cars have today…to some degree. If you drive hard, just change the oil a little early. If the MM would normally recommend changing the oil at 8,000 miles, change it at 6,000 miles. Over 100,000 miles that would imply about 16 oil changes versus 12 oil changes. 4 extra oil changes over that time frame will cost what? $200? $30 per year? Cheap insurance if you are worried. That applies to any Civic or the 1.5 Accord. But make sure you drive a 6MT-Civic before you make a decision – very smart, fun car for the $.

The MM accounts for hard driving by virtue of various sensor inputs so one does not need to change the oil earlier than the MM recommends unless one goes a full year on that oil.

(Says he who has the MM currently predicting first oil change around 15,000 km but will do it at 10,000).

Hard driving? Yes. Fuel dilution? I don't think so. The degree of fuel dilution some 1.5s get is more than Honda anticipated and is therefore probably not one of the variables in the OCI algorithm. A little manual override on this one would make sense for those concerned. Perhaps a little sniff test. If you smell gas……

My last 6MT Civic was a 2008 Si. Sweetest gearbox I've ever driven, and that list includes some modern Porsche's, Audis and BMWs. I think the Accord has always had a more utilitarian clutch. Not sure, but it wasn't anywhere near the experience I was used to. The only other Accord manual I have to compare to is a 2001 5MT that my late grandfather used to drive. It was also not in the same league as the Si.

Your mileage may vary, I guess. If that's all you've ever driven, this one is probably very good.

Oil in the gas is not in the algorithm at all (in the public version of it - which was pub'd in 2003).

So far I do not smell any gasoline in the oil and the oil level has been as steady as a rock since I got the car. But I haven't been pushing the car much except on the current tank (#6). It could be that Honda have solved this in the wake of the Chinese CR-V episode and have carried that to the Accord. My car was built in April 2019 so almost certainly has all the updates. We'll see how it smells this winter. On that point I gave my accountant's 1.5T LX oil the sniff test back in March and got no gas smell and her case (winter short drives to work) is a good one for dilution.

Winter may turn out different. OTOH as mentioned elsewhere I'll be putting on a block heater to get the engine temps up ASAP once it gets below 0°C ish.

Wow, thanks guys for the replies. This weekend I went to 2 dealers, both don't stock MT accords. I ended up testing the hybrid, since I know for sure I don't want the CVT version. I have to say that I don't like seating position in the new accord, very low to the ground. Also, I can't sit straight in the back because of the sloping roof line and my families tend to be on the taller side. Maybe I should look for 2017 V6. Thanks again.

Honestly, sounds like you'd be well served by the Camry.

Best of luck whatever you choose :)
