Hi Everyone,

First time getting this car tested. Engine has 20,038km (12,451miles) This interval was November-April in a southern Ontario winter that was unusually cold and snowy; so I thought it would be the worst case for fuel dilution and moisture that everybody seems concerned about with this engine. I bought the car new. It's a manual car with no remote start, so not much idle time and I'm happy to see the results. I will likely continue with the 10,000km intervals.

Interval 1 - Factory Fill ~5,000km
Interval 2 - PU 0w-20 ~5,000km
Interval 3 - PU 0w20 9,729km (6,045miles) - this sample

Honda filters with each change.

Don't let Blackstone's fuel% number give you a false sense of security. If I'm reading the report right (the numbers are tiny on my monitor) the viscosity has dropped to 6.87. Starting viscosity on this oil should be 8.0-8.5. Something must be dropping the viscosity. I bet if you sent this sample to Oil Analyzers, your fuel% number would be at least 3%.

The wear numbers look pretty typical for a young engine and should settle down once you pass 20k miles.

How are you liking the manual trans? I didn't know they still offered that in the Civic, that's pretty cool. Maybe it's a Canada thing? I have a 2003 Civic with a manual. ;)
 
The car has been great so far. The manual makes it a little more interesting to drive. It does have rev hang, so you need to shift a little slower than I would like but I'm glad I got it. You can still get a manual but only in the Si and Type R. 2024 was the last year you could get it in other trim levels (mine is a sport touring). For 2025, you're forced to get a 150hp 2.0L with CVT in the LX and sport...and only CVT hybird for sport and sport touring trims. So 2024 was the last year for this combination.
 
If fuel was your reasoning for a UOA you picked the wrong company to use . I'm sure others will point you in the right direction.
 
Wow, a manual. As others have pointed out the fuel test BS uses is not the best. They use a "Flash Point" whereas you really want to use GC fuel test method. Oil Analyzers is a good alternative. Blackstone is great for their universal averages though. Thanks for posting your Civic UOA.
 
To pile on a bit, Blackstone's estimation value isn't just "not the best", it is useless. They have been shown to be wildly incorrect.
 
6.87 cSt is all because of fuel, very typical for Honda Turbo DI engine. The new PUP 0w20 is 8.8 cST. I increased my viscosity to Xw-30 in my 2.0T Honda engine. This is just to offset oil getting thin.
 
Everyone makes such a big deal out of the fuel dilution on the Honda turbo engines, but it hasn't translated into poor durability, as near as I can tell. Blown head gaskets, yes, but that's not oil related. As mentioned, you can move to a thicker oil, and/or change it more often. There is a guy on CivicX with 310,000 miles on his 1.5T, without cracking the engine, so there is some good history developing. Dude uses 0W-20 M1 oil. Change interval unknown.

Lets assume everything you say is true, what is the downside of running one grade higher oil? The Xw-30 will come out with 0w-20 viscosity, so you are technically within “recommended viscosity”. What about the same Honda engine in Mexico or Australia listing 5w-30 as an acceptable choice, is there anything wrong with that?

It is hard to estimate real damage due to fuel dilution and oil viscosity depletion. What are internals etc. Many engines go hundreds of thousands of miles, but their performance does diminish due to wear damage.
Also, 1.5T is basically an appliance engine in an appliance vehicle. If something goes wrong, people usually don't look bato figureing out whit was it. Fuel dilution is bad in every engine. Only in Honda's people are like: oh well, not really a big deal.

In various different places in the world, where CAFE isn't an overbearing presence, Honda lists 5W-30 as one of the oil options. Use freely, if thinning oil due to gas makes you nervous.

When we start to see engines with internal damage due to poor lubrication, then I'll be concerned. My personal hedge is to change the oil in my Civic every 6 months. Kirkland oil is $13.50/5 quart jug right now, and I bought a bulk pack of Pentius filters. What, me worry?

I know a lot of people who smoke all the street with oil-burning engines, and they don't worry the slightest.

Yeah, and you can just use 5w-30 and not wait to see engines with internal damage
 
Take this for what it's worth, but my 1.5T engine is just amazingly quiet. Even starting in the garage, there is absolutely no clatter. The loudest part of the engine is the fuel injectors.

Well, the dude with the 310,000 mile 1.5T Civic reports that his car burns zero oil.

What is the ratio between oil and gas there?
