Good day fellow oil lovers. (long post)
I am a member of the thin oil club, however i always believed sufficient hths was important.
about a year ago my parents bought a new KIA Rio( 1.25 engine, i maintain it) and I bought a KIA Picanto ( 1.0 engine ) and a Mitsubishi ASX ( 1.6 petrol engine). so 3 new 0 km cars.
Always doing my own oil change on all three.
After 10000KM each vehicle, i switched them all over to Kroon oil 0w20 A3/b4 ( Yes I called kroon to confirm A3/b4 and hths )

After the first 10000 Km all three had negligible blow-by. if you took of the oil filler cap, idle running warm engine, there was almost No air coming from it.
After about 6 months, i decided to check blow-by again (same way off course) The Rio, afther 10000km on the 0w20 is blowing like crazy. the ASX afther 12000KM on the 0w20 even worse then our 320000KM hard life 3.2 diesel pajero. upon removing the filler cap, really high pressure air was escaping from it! oil got every where! The ASX and RIO are driven a lot that's why the already have 10k and 12K on the 0w20.
The picanto only has 2K on the 0w20 and isn't having blow-by yet. although it appears to be more than the factory fill Total 5w40 the dealer put in all three cars when the where delivered.
is the 0w20 destroing the cylinder walls?
Afther 5w40 for 10K all three cars have close to no blow by at all! and 10k later at 0w20 they blow even more than the old perhaps worn 3.2 did pajero.
It really got me worried.
thinking about switching the picanto back to 5w40 asap. and the other's too.
all three cars are driven about the same way. always warmed up carefully, and cruised quite high speed. no wild acceleration's or racing.
What do you guys think of it.
per manual:
ASX: any oil viscosity from 0w20 to 20w50 in my climate is allowed at least api sl or sm. it say's as a side note: 0w20 0w30 5w30 0w40 can only be used if they meet acea a5/b5 or a3/b4. all others api sl minumum.
picanto say's all oil viscosity's 0w20 to 20w50. minimum api sm and or ilsac gf4
Rio same as picanto, but max viscosity 10w40.
I am really puzzled, judging by blow-by these are really are looking like old engine's having 300K.
