M1 AFE 0w-20; 6,000 miles; '11 Honda CRV 54,000

[Cardiobuck]

First run of M1 AFE 0w-20 with M1 oil filter. All previous UOAs were done with the COP made Honda full synthetic 0w-20 and OEM filter.
95% city miles, 5% HWY, daily short tripper. MM light was at 15%.
Replaced with same oil and filter. Impressed by improved TBN here versus prior oil, less impressed by the filter given the retail price.

DIY oil change or stealership?

Nice. It works. 6 month intervals work for your CRV.

I have a 2003 Element with the same mileage. I only put on 4K miles a year and 75% city. I change mine at 6 month intervals with dino. I don't do UOL but might if I ever suspect a head gasket problem.

I am using 5W20 in the winter and 5W30 in the summer. I try to get up on the highway once a week to minimize fuel dilution and burn off water in the oil.

Short trips really move that MM, Our 2009 CR-V does mostly highway trips and will go 12,000 miles to 10%.

 

[Gasbuggy]

I would add some mileage, maybe run it to 0% with that oil.

I've come to respect the MM algorithm. You can always deviate(and I have in the past) but I've not seen any evidence that anyone has had to.

Lots of fuel, but the Mobil stayed in grade (just) versus the others.

I can see why Honda think their engines will be fine on 16s.

+1 lots of fuel for a non-DI motor. Regardless, your UOAs show no reason to change. I'd forgo the UOA cost and simply keep changing via the MM. It's proven to be spot on.

 

[Shannow]

zuluplus, I agree with you completely...it was an observation not criticism.

 

[tig1]

Easily a 10K oil.

My thoughts as well..

 

[Shannow]

What will the viscosity and flashpoint be at 10k?

ie, what makes you think it will go 10k in this application?

My thoughts exactly. Going from 6K to 10K is a big leap of faith here. If I was thinking of extending that OCI I'd try running the MM to zero, and get another report. Then work it up or down from there. We have no idea what the viscosity and flash point will be after another 4K miles on that oil.

It looks like running the MM to 0 might be spot on.

 

[tig1]

No leap of faith for me. Where is the evidence it won't go to 10K is the question you should ask.

 

[zuluplus30]

Fuel. Flashpoint. Insolubles. Not sure I'd make a 40% jump in OCI based off this UOA. If anything, I'd run the MM to 0% which should give him roughly 7200-7300 based on his usage and resample. I suspect that may be about all that's reliably left here. Don't forget his usage is "95% city daily short tripper". I understand 10k works well for you with M1, but for the OP's specific application I'm not sure its his best course of action. Having said that, I'd gladly concede to a satisfactory 10K sample from the OP.

It's actually a 60+ percent increase in duration.

Given that UOAs are a tool for oil serviceability, this is indicating that the oil life monitor as developed by Honda's engineers is about spot on.

Seriously, you are just plucking that statement out of your rear end...

What WILL the viscosity and flash point likely be at the end of your 10,000 miles, when it's only just in grade at 6,000 ?

He summed it up pretty well I think.

A $30 UOA and no leaps of faith, or guess work. From 6K miles to 10K miles is a big leap.

Sorry I should have been more specific. 10K would be a 40% increase over what the MM would call for at 0% (roughly 7200 mile OCI). You're correct its almost 66% longer than the current UOA interval.

In this car, with the way it is used, I disagree. Remember its duty cycle is 95% city. Poor thing spends 1/2 of it's life at less than full operating temp. By saying it can do 10K you are telling me to keep it in another 5 months and do another 4,000 miles.
With 6K oil changes the flashpoint range is 340-380. And all samples are taken after my 40 minute highway loop(virtually the only time it is on the hwy). I don't dare post a UOA without the highway loop first: everyone here would be telling me how messed up my engine is and how I need to check this part and that part.
You think 10K with 5 more months is a good idea? All that time at less than full operating temp running rich and leaving behind more and more fuel?

I like the M1 AFE and I like that the TBN here is higher leaving a little more headroom than the previous oil but my plan is to keep her at 6k.
Now in my Accord, the 80% highway car with M1 EP, yes sir it will be there for 10K.
