18 years of 0w20 motor oil at Honda
- Thread starter Snagglefoot

Have a 2005 Pilot we purchased new. Currently 203k miles and up until 3 yrs ago all oil changes were at dealer (always had a discount coupon so wasnt getting raped on price). Since then, have been doing it at home with either 10-30, 10-40, or 0-40 M1. Have always changed at a 3500-5000 mile interval. No internal work and the engine does not really require any topoff since going to M1.
Minimum required HTHS viscosity, which is what matters, is less than 12% more viscous for xW-30 than it is for xW-20.
Lol, I'm certain. If I didn't have the oil in it, it would have siezed up in just a few miles.
So yeah, it was the oil.
Wants vs. needs.
hths>=3,5 or no bueno
I have a 2013 Ford Focus that I bought new. It's 10 years old last month. 125K miles. GDI (non-turbo). Ran 5W20 it's whole existance. Zero issues or concerns, runs strong, no consumption or indications that 20W has caused any problems. Lots of VW MK7 GTIs running around nearing 100K miles on VW508 00 0W20. You jsut don't hear about drama. It's all online spookery. Would I track my GTI with 20W? No. But for most folks just driving around...it's fine....
Unfortunately Honda GDI turbo dilutes oil with gas very significantly to the point that 0w30 viscosity drops to 0w20 or even lower. I am not comfortable with such drastic viscosity drop in my Honda engine and use higher viscosity
And in that case, sure, use the 30 or 40W or just change it more frequently. Even then...nobody is showing me that the 20W with fuel is causing blown up engines here....
Not all engines are the same, Toyota/Lexus GDI turbo are less of a fuel diluter as an example. Honda GDI turbo been around since 2017, so it got 5 years of history and not too many people are 200k or more miles. We will have more data later.
To me the fuel dilution issue is mitigated by shorter/more frequent OCIs, not necessarily thicker oil even though again...whatever floats folks' boats here.
Shorter OCI did not work. I cut my OCI from 7k miles to 4k miles, and fuel dilution was the same(5%) And its mostly highway driving also.
I have a friend that has that kind of mileage con her Honda. She gets the oil changed when the monitor tells her. Seems to be running fine.
Is this the 1.5L? Yeah, so use the 30 or 40 to get some room on it. Won't hurt it. What does the ending viscosity on the 20 come out at?
Its 2.0 Turbo. My viscosity was 6.6 with 0w20 after just 3500 miles
I can see why you want to move it up a notch.
hths>=3,5 or no bueno
This is also my criteria for oil selection.
That said, all my current vehicles specify 'high' HTHS oils. But even in previous cars that specify *w20 oils I've always stepped up, but that is only because it gives me the warm fuzzies.
