Not only is that sound logic, but our long-term oil analyses do indeed support it. Bearing and ring clearances are typically much tighter on cars running 0W-20. A heavier weight may not flow as easily or sufficiently lubricate these areas immediately following startup on a cold morning.
That...
I haven't been too active on the forum as of late but wanted to come back and share an update:
- 2017 Civic Si Sedan
- 137K (tuned since ~38K)
- Mods: KTuner OTS tune with a few tweaks by me.
- Driving behavior: Mostly commuting (16 PSI) with some spirited drives in between (23 PSI).
- Issues...
You’ll need to have the car on a lift or ramp so the suspension is loaded with the full weight of the car. Have someone turn the wheel while another is underneath inspecting the bearing assembly and spring position.
Disclaimer: be absolutely sure the vehicle won’t shift position on the ramps. 😉
Check the bearing assembly below your top hats. They can wear down prematurely and exhibit the symptoms you’re describing - especially on track setups with aggressive front negative camber.
I typically inspect on an alignment rack but Jack ramps should also work. Just make sure the suspension...
Update at 112K.
A little late to post, but after nearly a 12 week downtime the new injectors finally arrived from the dealer. Car now runs great with the new injectors in.
Honda’s inventory backlog has been disappointing, to say the least. And I’m hoping this is the last time I will have to...
Swap the shocks (not struts) and mounts. Then swap back the mounts/bushings if the noise follows to the other side. Only other thing that comes to mind is the LCA or trailing arm bushing.
This is my typical mileage… this one after a 500 mile full road trip through back roads, side streets, and some scattered traffic. Pretty much normal/spirited driving the entire way.
115K on the odometer on KTuner Map 2. 😎
MSRP is $601. Anything above is an overcharge from the dealer.
Injectors are still on backer online but can be requested via CBO through any Dealer.
EDIT: Getting word that online dealers will soon be stocking the injectors. You can try Jim White Honda or Honda Parts Guys to see if they’re...
Here are a couple photos. The kit includes the fuel joint (not fuel pipe) which is strongly recommended to be replaced due to the crush assembly.
The part ID for the injectors is similar but includes an extra 0. To my knowledge, these can no longer be purchased independent of the fuel joint...
After riding on the HFP system, I will say it is arguably the best spring/damper combo you can get under $2K. IMHO, there's no other setup that offers the range of flexibility that HFP does.
I was very skeptical of what was being described as "softer" spring rates. But I actually think they are...
I was quite surprised myself. After doing a bit of digging, and as mentioned earlier in this thread, this appears to be their third mass injector failure in under 5 years. Why they didn't rotate in another supplier like Denso is beyond me.
I've heard there are still over 2K prepaid orders in queue.
If it were me, I'd take to the dealer to have hooked up to the HDS (or have your mechanic do if he has one).

There are plenty of varying opinions on the topic. What you display often depends on what you want to monitor in real-time. Here's what I track:
AFR
STFT
LTFT
K Control
K Count (or DIFP)
ECT
MAP/Boost
IAT 1
IAT 2
When my injector began leaking, my AFR immediately went rich at idle, my K Con...
