bro, it may seem technical and overwhelming yung info and numbers, its just says na kapag mas malapot ang oil mas matagal siya makapasok sa butas... lalapot siya kung malamig ang ambient temperature... eh kahit nasa baguio pa tayo eh hindi yan aabot sa freezing temp, so it will still flow sa orifices just a little bit slower if not almost the same to 0W to 5W...

we can never eliminate engine wear during start up, unless meh mainbento na oil na hindi mag settle sa oil pan...
its like us humans, we age we get sick... so ganun din engines, it will get old and will have breakdowns.

kung meh budget ka go for fully synthetics... and dapat dilemma is to go fully synthetics or not,
hindi na dapat pag isipan nang malalim kung 5w/10w/15w... "unless you want fuel efficiency"
Generally agree ako dito...

Someone please explain why xw40 in diesel's? | Heavy Duty Engine Oil (HDEO) - Diesel/Gas Pickups/Trucks/Vans | Bob Is The Oil Guy

dnewton3 states on another thread:
Fuel economy is mostly controlled by driver attitude and style; the foot is the main contributor/detractor to efficiency!
A realistic view of efficiency gain is likely 2% or so.
