There is 0w-20 is manual
Pretty much you can run 20,30 and 40 in this car judging by manual. In horrible Moscow traffic I would follow severe OCI.

yes, winter adds some wear. I'm testing 5w-40 oil in my Hyundai Tucson 2,7 L since Jan 2011. 5300 miles OCI from Jan to Apr - 30 ppm of Iron. 6120 miles from May to August - 18 ppm. I'll show full test results next week.
No problem to find synthetic 0w-30/5w-30 in Russia. The real problem is to find xW-20 and 10W-30. xW-20 we can buy as Genuine oil for japaneese car, but 10W-30 - nobody knows why this grade does exist?

At least in my city (about 700 km to the East from Moscow) this was a real problem ;-) Almost all oils were xW40 or xW50.

I like it. It has much less viscosity improver and more shear stable. In Maryland (where I am now) typical winter temperature is -5-7 C in morning, so 10W30 works fine.

avss1, hello from Poland..
I'd use good injection system cleaner first - there is quite much fuel in your UOAs so maybe the reason is quality of fuel (please don't take it personally - I see the same in Poland)? I'd recommend BG44K once a year.
0W-30 for Honda is OK for your (our) climate ;-) if for 1 year OCI or 0W-20 for winter + 5W-30 for summer.
5W-40 for Honda is too thick IMO as well.

wlyszkow, thanks , i think 5w-30 will be a good choice. 5w is enough for Moscow winter
p.s. I visited Krakow last month. very, very beautiful town.

It's close to impossible to find a 5W-20 oil in Russia. Even 5W-30 ACEA A1 oils are generally regarded as dangerously thin. Not sure why even the car manufacturers tend to shy away from such oils. I guess the main reason the Fe numbers are so high is that in Russia they still illegally use ferrocene octane boosters. Most used spark plugs I have seen on Russian forums have red residue on the insulators.
page 416 and 418 is some oil info. Looks like a 0w-30 would be ideal all weather oil.
