Hi all, wow my first post in this forum. I've just gone thru my 3rd (10k) servicing. Bought Mobil Synt S 5w40 from Taiwan (NT185 only!!). So far, my FC with mineral oil has been pretty good about 14.5 and currently it's around 15km. Well I do drive 60-70% on e highway...
Nonetheless, I'm tempted to try Amsoil 5W30. Read the other threads about it and seems very good, but is it recommended to drop from a 5W40 to a 30? Thicker to thinner lube doesn't sound right to me.
