It's my opinion to always start on the slightly thick side, and shear into grade, rather than start in grade, and run the oil too long when it' too thin.
Therefore, the last 12k miles (since I've owned the car), I run a mix of 2.8 quarts of M1 0w20AFE and 1.4 quarts of M1 0w40. This give me a good 30 weight oil with good start up flow.
I could also run M1 0w30 AFE as well and not have to bother with the mixing.
I don't be putting any finished 20 weight oil into my Honda. Unless it's mixed with something a bit thicker.
I also run Napa Gold and Napa Platinum filters.
You said the you are betting that 20wt oils will be a 10wt the last 3-5K of a OCI. Have your seem that are is this your opinion? Actually 20wt oils appear the hold their vis very well. I have never seen any evidence of this kind of shearing with the 20 wt I use, and haven't seen that with others as well. please explain.
I agree. I have only ever used 20wt oils in my '04 Accord and am nearing 130,000 flawless miles. According to the uoa's I've done between 7-8k miles the oil has been above or nearly at 8cst (100 degrees) in every one. In my application and with my driving, the 20wt does not appear to shear much:
UOA's
To the OP: My car has seen mostly Sopus products since 40k (up to 40k it was Kendall gt1 5w-20 at a service station), PP, PYB (pennzoil yellow bottle), Shell, and Ultra. I did try Honda 0w-20 sm for a few changes, did not like it, and have since gone back to Sopus. Oil filter of choice has been a Pureone.
This said I'm convinced now that my car would be running equally well on any name brand conventional, semi-syn, or synthetic in the recommended grade. Likewise, any name brand filter in the appropriate size would have performed fine. The UOA's I've seen on this engine seem to confirm that:
A) The K24 is easy on oil and will run well on virtually anything if properly maintained.
B) The K24 will outlive the rest of the car, which can be said for most engines today, if properly maintained.
Question: what is your planned OCI? Are you going by the maintenance minder?
