Ditching 0W20?

But does this Honda engine have lube-related failure modes?
Would 15W50 weight oil and an oil pan heater (for startup) and a pre-lube accumulator and a superfine add-on filter move the failure point from 275,000 miles to 300,000 miles?



So your saying the oil grade does not matter?

So much information to consider here; thanks to all that weighed in with a valuable thoughts. I'm going to noodle on this for a few more weeks but I can see the value for sticking with 0w20 and also ditching it for a 30 weight variant.

I'm determined to get this car to 300,000 miles so I'm going to start planning some road trips and I'll start with a UOA. Then I'll pull the trigger on which oil weight I'll be using for the next 250K miles.

I always look at what the manual says to use for Severe Service and that grade is what is really best for your engine protection wise.
I don't care about mpg over protection.

We can't noodle for a few more weeks here in Michigan. If we do, the snow might be too tall - to change the oil.

Some truth to this and members are not alone in the trail and error bucket. How about Ford? I'm a lifetime owner of mostly GM/Ford with a few Mopars here and there and feel GM has managed lubricants best of the B3 … case in point how many others accept Dexron ATF and have for years …
But went through heartburn having my first 5.3L on 20's until I read up on changes like oil coolers, oil pumps, piston oil jets, and upgraded capacity (now 8 quarts) … Now I just trust the OLM and M1 EP … even have brought myself to accept the PF63e (while waiting on new FU) …

Based on the information given: powerful V-6, OP praising its speed and power, hot climate that seldom drops below 50 F, SoCal traffic and average highway cruising speed, short OCI, out of warranty....this seems like a good case-study for moving to x-30 oil. OP also does not care about the tiny mpg hit.

Not saying x-20 would not protect the engine till the car dies of old age, barring drag racing or truly extreme aggressive driving, but for that engine, in that climate, for that usage case and with no warranty concerns, I would consider going one grade thicker.

For someone with the same car in the mid-West or Northeast, where temps hit zero in the winter, who drives gently and mostly highway miles near the speed limit, who obsessively tracks mpg, who changes oil at 10K....in that case a full-syn 0w-20 makes sense.

Interesting that owner's manuals in some countries mention these factors and give a range of acceptable oil grades, but in the US it's one size fits all.

My friend who has a 2002 Odyssey nearing 300,000 miles uses Castrol HM 10W30 per quick lube shop sticker (the oil cap says 5W30 but the manual says 5W20).

I'm wondering if I should use some of my clearance PP 10W30 in my Accord,or should I stick to 5W20 that I've been using,and save the 10W30 for the Z and Mustang?

When the K24 powered TSX came out,the oem spec was 5W30 while the K24 powered Accord of the same year was specd 5W20. Then eventually both cars were back specd to 0W20. The only difference I can tell engine wise is that they went from a metal plenum to a plastic one. I wonder if there were any internal changes made?

Are you serious? The K24 is not the same in those two cars. The accord has lower compression and less rev ability then the TSX's K24. So one is intended to be a grocery beater while the TSX has the change of being driven aggressively while revving higher in VTEC. That's why the TSX got thicker oil.

Sorry to get off topic. Needed to correct bad information from spreading.

Try again.

 

[Kamele0N]

can I have a personal question for all of Americans here...

Common consensus here is...ok 0w20 is ok if you are driving your car "softly" Otherwise if you are normal driver it is vise to use thicker oils...

Are you Americans in general such a gentle drivers?

Some mix between elderly drivers and hm.....

Hahaha

EDIT: I feel sorry for a Dave1251...he gonna be mad on me again

That's the thing. I DON'T know,hence the reason for the post. I understand the higher compression thing,BUT,are there any internal differences lubrication system wise?

Ok,another question per my post. Why did the TSX get back specd to 0W20 if it needs thicker oil because it revs higher?

Exactly, shame you ran the 0/20 50k neverless I'd be looking/listening close on 10/30 10/40 pick your fav and enjoy the luxurious result.
