And sir, yung mga pangalan lang po ng maker ang binabayaran natin pero still the motor oils falls to content of percentage on mineral oil and synthetic blend and additives po....pag-nakadecide na po kayo ng motor oil stick na po kayo dun kasi mahirap din po ang palit ng palit ng motor oil. Yung mga stated brand ko po ay abot kaya ng bulsa sir. and ang alagaan po natin na isa sir yung ECU natin po kasi control lahat tayo ng ECU...please ask sir Tp, sir Ranic(aka Grand lakay) and Sir spyke for the lecture on CRDi-egr,CRDi-VGT and Clutch proper launch and release po.

Thanks for the input and explanation, i just notice kasi ang casa yun turbo xp nila na fully synthetic (15w40) eh parang malabnaw na pag dating ng 5km, na dapat every 10km ang palit, city driving lang ako at usually low-revs lang kasi malapit lang byahe ko ;) baka sa 15km checkup ako mag palit na ako ng langis ulit ;)
