You mentioned already done 215k km, that is why I did not recommend FS which is of thinner viscosity. Some had problems like oil leak and oil consumption upon changing. Moreover even though FS cost more it does not mean longer OCI. OCI should follow car manufacturer recommendation.
I used to drag my FS oil in my VR to 10k km, but I find it turn my engine internals darker (dirty), that is why I say nothing beats regular OCI where you remove the dirty oil and whatever that is in it.
Interesting. Reminds me of one of those oils that I used before. FS with lower viscosity. Halfway before OC (in terms of months), already half or 3/4 gone. Have to top up. I suppose gotta start DIY when it comes to changing oils nowadays. (at the same time, show my 'awesome' mechanic skills to the wifey while flexing those muscles and chewing some kangkung
)Anyway, was browsing the net the other day looking for next oil to use and saw that HKS and M7 are sold locally which offers Fully synthetic / 100% Synthetic (as quoted from their respective website) with 10W-35 (HKS) and 10W - 40 (M7 Japan version with the tin besi). Any of you guys tried it before or your own thoughts about those?
