HPL SuperCar 5w-40 for 2.0T Honda
- Thread starter Hohn
- Start date
So 30 is the highest recommendation, and you ignore that and run thicker regardless?
0W40 shear to 30 immediately on start-up, just ask any American
Yeah, thats what I do now. A5/B5 purely for emisson in the book, run A3/B4. Like the engine-family did when first released.
Spend $20 on Amazon and get a scope. There’s NO WAY you need to restore anything.
Older K series engines (K20a, k24a) are quite different from the K20C series which are natively turbocharged.
The owner’s manual excerpt above shows that even 5w-40 is within the manual for this engine in other markets when it’s used in the Civic Type R.
I have no context that would cause this post to make sense to me. Who are you talking to? Who’s talking about restoring an engine with 21k miles on it?
So, now the final challenge— which HPL 30 grade? The crazy high Calcium in the 10w20 no VII kinda of scares me for LSPI that the 30 grade no VIIs Euro oils might also have excessive calcium.
Thus far I’ve been running V Power so maybe I just stick to premium to prevent LSPI and run any Euro oil I want to get the stouter add pack?
I mean, it seems to me that if LSPI is a concern, and you’re already running 93 octane, one might as well just stick to premium fuel, consider LSPI a non-issues and run the the stout HPL oil add pack and have no worries.
Right?

I have a 2019 2.0t and have been running 0w20 but after doing research on the non cafe recommendations in Europe etc they recommended 5w30 so I’m planning on running 5w30/0w30 going forward. Figure it couldn’t hurt anything and fuel dilution is pretty common on uoas for the k20c4
Fuel octane rating has not been shown to affect the occurrence of LSPI. A couple of papers I've seen have not shown a correlation.
The specific fuel composition that is used to achieve a rating might, but even that is inconclusive. Engine design, displacement, and to a lesser extent oil are the known contributors.

That’s why M1 ESP 5w30 would be a good choice here. It has the same 3.5 HTHS as M1 0w40, and will retain its viscosity very well.
Your very first sentence on your very first post?
1) You acquired a Honda with 20k miles
2) you drained oil to run a change of VRP to clean out deposit
3) you now have no idea how talking about not needing to remove any deposits on a 20k mile engine has anything to do with your post about removing deposits on a 20k engine? Unless you’re trying to say removing deposits isn’t the same as restoring which , I mean, it’s one and the same and even the name of the R in the VRP you specifically speak about.
That doesn’t make any sense to you at all to directly reply to your post on your own topic? Nothing rings a bell?
