welcome I work with a guy from Russia! Wow - that's a lot of Iron. There's some wear going on in that engine. Those are not the best driving conditions at all and I would not extend the oil changes out too high. Have a great day over there! smile

agree. I think that silicon is a reason

Yes, change the air filter and check the air flow system for leaks. thumbsup

ha! oil change was done on 9320 miles (Official Honda service - 15 000 km = 9320 miles OCI) frown then there were 2 tests of the new oil - virgin and after 217 miles (actually a fresh oil with some part of previous LM). Important point that TBN (ASTM D-4739) decreased from 9.74 to 7.18 after 200 miles! Acid components as well as Iron and Silicon come from previous oil.

Daaa, i'm starting to think that the oil might be a little too thick for this engine. In the US, this engine would spec 5w20. If the oil is too thick, it's taking much longer to get to where it needs to be, so engine wear increases. You also mention that the oil was changed @ 9,300 miles but the report shows that you sampled @ 7,450 miles... if you added another 2,000 miles after then sample, i'm sure EVEN MORE engine wear was done during that time.

I too wonder why 5w-40 is being used. Isn't Moscow a colder climate, like northern US?

Moscow climate - -10-20oC in Winter (sometimes -25-30), +25+30oC - in Summer (sometimes +35). 5W-40 is the 2nd popular grade in Rissia after 10W-40. 5W-20 i think less than 0,5% of total volume. our drivers think that use of low viscosity oils like 5W-20 lead to engine wear.

thanks grin as i mentioned this is not my car. for me LM is too "marketing" oil. i prefer another brands - mobil/castrol/lukoil

i would have to agree that the 5w-40 could be too thick. what does honda recommend? i would be surprised if it was 5w-40. uoa's of 5w-20, 0w-20 in the honda 2.4 show minimal wear. this particular engine is "easy" on oil. have your friend check the owner's manual.

My experience of 5w40 in a Canadian winter (which is just as bad) in an engine that also spec's 5w20 didn't yield results that looked anything like this.

5w-20 does not exist in Honda manual for Russia (p.410-411) wink , sorry for russian version http://www.hondaonline.ru/docs/CR-V_guide.pdf

Hey, I'm not telling you to run 5w20, LOL. I'm saying there really shouldn't be much of a difference in the UOA results. I used both Mobil 1 5w20 and Delvac 1 5w40 and the difference between the two in terms of UOA results were negligible.
