Hallo everyone, I have 2 new cars a 2.0 honda cr-v 4x4 and a kia rio 1.25 They both have coverd their first 1000 miles, so i did a first oil and filter change. for both car's i used mpm 0w20. link: http://www.mpmoil.nl/pdf/pds/MPM_05000JP_pds_EN.pdf Look at the incredible viscosity index 199. Both engine's sound and feel great useing this engine oil. But i have a concern: I intend to do fairly long change interval. 15000mile to be exact i always did this to all my cars. But if you look at the TBN of this oil it say's only 2.4 Is this a problem? thank you verry much and sorry for my english.
