2016 Honda Civic with 375,000 miles, 1.5T engine - Reddit link

[scotty.honda.dog]

I thought we might be interested in this Reddit post/discussion. 2016 Honda Civic CVT with 1.5 turbo engine (fuel dilution candidate) with 375,000 miles. Seems to follow the Maintenance Minder intervals and whatever oil the dealer uses. Said they drive 4000 miles a month.




Talk amongst yourselves.

Lots of highway miles. Fuel gets burned/evaporated off and doesn’t build up in the oil. Engine is fine.

I was curious and did a quick search for HG and only returned one.

Non-news, news....any car driven 4k a month and maintained will last that long.

Except they always seem to be from the same (2) mfgs. JMO.

4k a month is almost 50k a year, lots of highway driving, so less likely to suffer fuel dilution.

It's not a Subaru

Seems to be the 2018-2020 models, but it may be too soon to tell due to mileage of the 20-23s.

High mileage odometers are all over reddit.

But all the grandmas who just drive to the grocery store once per week are another story.

Easy Highway Miles.

You mean any Japanese car right.

Not surprised. As a 1.5T and 2.0T owner, the engine will run for a long time if you are mostly doing highway miles. He is averaging 41MPG.

For Reference, from the EPA: https://www.fueleconomy.gov/feg/Find.do?action=sbs&id=37284 : 41MPG is highway, 31MPG city, with an average of 35, and tested average of 37. My 2018 Camry with the 2.5L is rated 30/40 and I average 37 with 80% ish highway miles. This guy is hyper-miling, and who knows if he took his turbo off for fun /s.

Most of these 1.5T motors fail at the headgasket or the piston due to LSPI, which can increase thanks to fuel dilution as flashpoint of the oil (and contamination with fuel) falls. Most people I have seen and know who have had issues with these turbo honda motors, drive mostly city, where there is a plenty of heat soak, idling, and lugging.

That's a lot of miles and those Civics are great cars.

Just saw this post today and I just rolled over 300K with my 2006 Acura TSX. Owned since new. The Honda 2.4 was probably one of the best motors ever made. I WANT this car to die as I want to get another one, but it won't. Lol....

Fuel dilution has no impact on LSPI.
LSPI is a caused by engine tuning in combination with using an oil which has little to no Mg but high in Ca.

If an engine is prone to :LSPI it is best to use an oil which meets API SN+ or API SP.

Influence of Fuel Dilution of Crankcase Oil on Ignitability of Oil Particles in a Highly Boosted Gasoline Direct Injection Engine

The relationship between fuel dilution of the crankcase oil and low-speed pre-ignition (LSPI) was studied experimentally with a highly-boosted 1.8L turbocharged gasoline direct injection (TGDI) engine fueled with RON93 gasoline. It was found that properties of oil particles entered the engine cylind

All you have to do is get the flashpoint low enough for self ignition. Regardless of engine, this can happen. Basic physics.
Heck, this has been discussed on BITOG before...

Again it's the oil additive composition which is the primary driver. LSPI is the entire reason behind the introduction of API SN+ which was carried over to API SP. You have these gas engines which are tuned to operate like diesels for maximum torque at low rpms.

The BMW N54 (2006-2016) is TGDI and was a fuel dilution monster yet it was fed a steady diet of API SM/SN. No LSPI for that engine because of tuning.

I mean any car....with few exceptions.

DI engine with high miles isn’t worth analyzing because it “has had an easy life”. DI engine with low miles “hasn’t been driven enough to see the damage”

These guys are sure though, that DI engines and dillution ARE a problem, even though there’s zero evidence. Apparently it takes 200k miles of driving 5k miles a year for dilution to take its toll, for everyone planning to keep their cars for the next 4 decades

Sure, it probably is, and fuel doesn't burn it turns into magical pixie dust afaik.
