Hello everyone. I have a new analysis of my vehicle with high mileage. This time I have exhausted the oil change to the manufacturer's specified interval. As you can see, the element concentrations from the 10000 kilometre interval to this longer interval have not increased excessively, but rather a lower concentration of the elements present than on the first 10000 kilometres after the oil change. I think I will keep the 20000 kilometre interval. This engine really seems to be a very solid construction.

Thoroughly impressive.

Still at 9.2 TBN

Is this the same M1 0w40 that we have here in the states?
 
This engine has been operated exclusively since kilometres 20000 with Mobil 1 0W40. Initially with the new life, then the switch to the FS 0W40 and now to the FS 0W40 with the API SP specification. Also when refilling the engine oil I meticulously paid attention to the fact that I only used this engine oil. The car is completely maintained at Honda. In addition, I have made and listed a cost statement since the first kilometre (bought as a new car) with all costs for insurance, fuel, maintenance as well as repairs and everything that goes with it. If you are interested, I can also set this up, but then it would have to finally translate it. 😉😉
For me there was never a reason to try a different oil, the UOA are excellent and also the compressions on the engine are excellent. Except for adjusting the valve clearance, nothing had to be done on the entire engine and transmission. Price performance is mobile 1 simply the optimum.

It's interesting for me that the element concentrations do not double with double mileage, but only "slightly" increase. there Many People think that an oil after 7500 kilometres is at the end. My UOA‘s looks Good, very good.

So you added 1.8L and the tbn is 9? That seems far better than expected. Are you sure this place is testing tbn correctly. It just seems way too high on all of them imo though I expect it to retain it better than standard oils.
 
You can see it in the top line, there are 1.8 litres seen on the entire interval.

I find it very interesting that the higher wear predicted by some "experts" (especially in German forums) the higher the mileage of the oil is not to be seen. Although minimal, I have minimally more element concentrations when changing oil after 10000 kilometres. So I will stay at every 20000 km.
I am happy to be here with any real oil experts 😉
Among other things, it is said in german Forums that after 250 hours of operation the maximum limit of the engine oil is reached and should be changed, i am loughing Lois about that, because I drive 370 operating hours and I could use the oil even more. I therefore prefer to make my own experiences than to listen to such “ignorant”. Here at bitog I have also often seen good results from longer oil intervals, you should spare the resources a little, so I only change according to the manufacturer's specifications.

Not an expert but M1 0w40 has always been held in high regard in the US. This 12k mile OCI is perhaps a testament to Honda engineering combined with the comparatively low power density of 76 hp/liter of displacement.
 
I have the valves adjusted every 100000 kilometres according to the maintenance schedule. At 500000 kilometres I will perform a new compression measurement and see how this will be this time or what change there is. I will report. Thanks for the words.
 
What do you think, should I try another engine oil for my car? Maybe going up with the viscosity? Which one would you prefer?
Few Months ago I had an idea to use a low viscosity engine oil ( oem is 0W20 ), what do you think?
 
Kinda wondered if it would be safe to use M1 or Amsoil 0w40 in my 2017 Honda Accord Sport 2.4 GDI. Would it be too thick? Would still like to do 8-10k mile oci. Currently at 370,000 miles. Took into Honda today with 15 qts of M1 and a few filters to flush the motor if there was any foreign particles. Timing chain was getting done, vtc actuator, guides, lazer iridium plugs, valve adjustment.

Too thick for what?

I mean…370k is a huge milestone. Why not stick to what’s been working?
