Long Term 5w-30 use in Honda 1.5t

[Shel_B]

What's the question?

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

You've made all the classic BITOG mistakes, and still no banging noise?! I bet your hearing is failing you. <G>

That's a pretty bold statement considering there are likely thousands of Hondas on the road with over 300k on them that have been running 0w20 since new.

I lost track of this thread some years ago, but I can't remember if this guy made it 600,000 + or more on an original engine in an R18 Honda Civic.

Either 5w-20 or 0w-20 for the duration:

800,000+ miles and still going strong

Is it GDI Turbo ?

No

So how is this relevant? Just because its Honda we need to expect same longevity with a new engine design? The non GDI version does not dilute oil with gas for one thing

You know the answer already. No need to troll.

2022 Civic Sport Touring 1.5t currently running 0w-20 as the manual specifies and filling up with Top Tier 87 Octane but I've heard this L15B7 and variants do show 5w-30 in owners manuals in other parts of the world. However there may be other differences such as fuel which is more "potent" outside of the US which may be a factor in this (I don't know if it is or not but just thinking)

I'd like to keep the car for a long time as I'm already over having a car payment, curious if anyone has used 5w-30 long term in these engines and how they have been holding up. I don't have many short trips and drive pretty gently typically for MPG, but willing to trade off savings a few cents or a dollar per tank if it gives me a bit better protection. I'm doing 17,500 or so miles a year so getting to 200k would be nice, the car is really nice and versatile enough that I don't see a need for something bigger since we do have a CRV 1.5t in the house (which I'd put on the same diet if I make the jump to 5w-30)

Currently 5k OCI with factory filters and M1 EP 0w-20, would be using the same interval and filter but with M1 EP 5w-30. I know this has been covered here before but hoping to get some more feedback in one place or maybe someone has newer info to share.

Keep in mind that about 60% of what you read is is smoke being blown towards your Wah-Zoo. Y%MV

For the last 30 years people been saying the same thing.

"this time is different."

And I'm still waiting for that to come true.

Ok, we will all just take Honda word on it.

Brother it's just motor oil. If you want to be like the guy above that took a stock Honda Civic and ran it for 620,000 miles using exactly the oil Honda recommended at 12,000 mile intervals, go for it.

If you don't trust the company, don't buy the car. It's that simple.

It might be simple for you, but not for others. If its so simple, why even discuss anything?

That not 100% true, my wife's R18 Honda Civic definitely put some fuel in the oil. Link to UOA

The problem is worse in GDI, even for long drives on highway

I was in the same camp of just trust the manufacturer, and while I do think Honda makes good engines modern engines as a whole are a lot higher stress than the old 115hp single cam D16 my old Civic used to have. Practically speaking going to the 5w-30 has not affected my drivability or MPG in any meaningful way, but if it helps me avoid some repairs down the road it’s worth it. That may not mean total engine failure but even doing a better job protecting the turbo, or avoiding deposits in the oil lines, etc. maybe it’ll help keep the piston rings clean and clear reducing blow-by down the road. I’ve also installed a catch-can as a preventative measure for whatever blow-by does occur, and to keep the valves clean.

My coworker told me to watch out for my oil seals blowing out from the added pressure, but pretty sure that’s not how that works.

theoretically...can having a fuel with too high cause problems say in the winter? Number indicates it detonation, but could too high be just as bad not getting complete burn off. For me, I get best from 89 e10 and 87 non ethanol at QT every other fillup. After doing all my math equations over the roughly 17.2 gallon tank, I get a mid 87.5 to 88 and some change. If I get too high of an octane it just doesn't seem to really make any returns on fuel economy or power

Winter fuel is formulated differently than summer fuel.

I stored fuel for generators in 2.5 gallon red plastic gasoline jugs and rotated out old fuel and stocked new, every spring and fall. If I left winter gasoline in a jug in hot summer temperatures soooooooo much vapor pressures built up that the plastic jugs would have soooooo much pressure inside that instead of rectangular, they were more like red round basketballs that you could still make out wear the corners were.

Identical jugs with summer gasoline did not have deforming. The vapor pressure is much lower.

If one tries to run summer gasoline in cold winter temperatures, there may not be enough vapor given off when starting a cold engine, and the spark-plug may become wet resulting in shorting out the spark-plug and a no start.

Again, gasoline is formulated differently in winter, compared to summer.
