Long Term 5w-30 use in Honda 1.5t

[Glenda W.]

Owner’s manual will state no additional additives are needed in the fuel and oil so why do dealer work try and sell additives flushes etc.

Dealers use to have tune ups, trans services, differential services, coolant services, etc. every 30k. Around the mid 90’s technology advances allowed services to be extended to 100k-150k. Dealers turned to BG and similar services to fill that gap even though oem’s send out bulletins that state such services void warranty. The worst part is the regional warranty rep would walk through the shop and see all the BG flush machines and didn’t say one thing. He also never tested the bulk oil tanks in my 12 years.

Amazing they’re crooks

The funny part is, I had a 2014 Honda with the 1.5 engine that had the manual spec 5w40 and 1 month / 10k km, then they switched to 5w30 in the service centers, and gradually to 5w20. In the exact same engine, in tropical India. What they did was to switch to a 6 month OCI once they switched to thinner oils. So even a 5w40 isn't going to hurt your engine.

1 month / 10k km

???

???

1 year / 10k km sorry

So far so good, MPG still seems to be about the same. We did get warmer weather this week and MPG is better due to not running the heater.

Any sense changing the oil more frequently than 5k?

Yea I don’t trust the dealers too much since they typically are instructed to parrot whatever the manufacturer wants, or just don’t know. You need to have a good trusting relationship with someone competent at the dealership and having worked at a dealer before I can tell you our “advisors” were just sales guys with their own quotas to meet.

I called a local dealer yesterday to get a quote for CVT fluid flush and asked about filters, after getting nowhere with 2 folks I got passed to some senior tech guy who said he’s never changed the filters in the transmission in 7 years and isn’t even sure they sell replacements for them (they do).

Filter replacement is probably not required by Honda.

CVT fluid change is routine maintenance on a Honda, not lifetime fill, so they will be familiar with the change and what is required.

Just because a filter is sold doesn't mean replacement is required during a routine fluid change.

THANK YOU, this is super helpful and exactly the type of response I was looking for as far as sustained use. Have you used M1 EP 5w-30? I think its a little thicker than Pennzoil stuff but don't remember. And I hear you on the fuel cost, I remember when jumping from 87-89-93 was about a dime a gallon, now its close to a dollar

You have to remember that you are asking "thickies" for advice. If it's a heavy diluter, I'd use 0 or 5W-30 if not go 0w-20. IMO YMMV.

 

[picklyrickly1073]

What are some benefits to the Euro oils like M1 ESP over M1 EP? I’m going to stick to 5w-30 but would consider ESP after I run through my small stock of EP.

5k OCIs and I live in a 4 seasons climate

IMO euro oils have a more robust additive package and meet more stringent approvals.

In the case of ESP 0w30 a nice high virgin oxidation(ester). I’m currently very happy with it in an Acura RDX. Soon to be going into a Subaru Outback after 4 rounds of Valvoline R&P.

I use 0W20 Mobil 1 EP on my Civic Type R with the 2.0 Turbo.

Look at every 2017+ CR-V you see on the street that is still running. 99% of those are running whatever 0W20 oil on a ~10k+ mile OCI, as per the Honda maintenance minder. You'll be fine.

Plus a generally higher HT/HS in 20- and 30-grades.

Most recent tank 37.2mpg with the 5w-30. Now deciding if I want to venture into Pennzoil Ultra Platinum when my M1 EP stock depletes

200 mile round trip from central Pennsylvania to Newark Delaware on Sunday, some highway mostly secondary rural roads, small towns, lots of red lights and moderate to heavy traffic, driver and passenger in car, outside temperature in the 50s to low 60s. Fuel, Shell 87. Overall mpg calculated was 37.3. 2023 Honda Civic Touring Sedan 1.5t CVT. Mobil1 5W-30 EP.

These are my long term averages in my 2016 Civic with the 2.0 engine and CVT. I definitely think the 2.0 is the one to get for the best possible fuel economy as well as not having to worry about fuel dilution in the oil either. I only use 0w20. During the 49.8 MPG run there I was using Quaker State Ultimate Protection 0w20. I do almost all highway driving and a typical day for me is over 160 miles of driving so I really don’t do any short trips.

(As an aside, I have hand calculated my MPG to see how accurate the onboard readings are and they are optimistic by 2%)

What speed(s) are you driving?

What speed(s) are you driving?

I drive this car at the speed limit everywhere in order to get the best MPG so part of my daily driving is on 80 kmh roads and most of it is going 100 kmh. It gets insane gas mileage when I’m on country roads where I can go 60 kmh for a long time. On the 60 kmh scenic road leading into Niagara on the Lake I usually get over 60 MPG for instance! The CVT allows for very low engine RPM at those lower speeds (around 1200 rpm!)

FWIW I don’t drive my Corvette like this! I’m 20 kmh over the limit almost everywhere I go in that

That's crazy how much better aerodynamics are on the Civic and a little more power too vs. the CR-V. If I drive over 65, the CR-V with the 1.5l turbo drops to like 28-29mpg. If I drive 55-60, I can get like 32-34mpg.

Don’t forget that the Civic is also very light, especially mine because it’s the base model LX coupe. It only weighs about 2750 pounds!

What's the question?

Wife CRV has used 0W-30 in for 6+ years. Extended OCI's. 1.5T. No frightening banging noises
