At par lang ba ang Valvoline compared to Baldwin & Fleetguard, if not better? How much po yung V0-106?

Lastly. Pwede naman yung DGU ko sa EK ano? 15W40. Sayang kasi yung natirang 1 liter hehe. Kaka-overhaul lang nun around 2 months ago and 20W50 ata ang ginamit na oil. Dapat yata nasa 10W40? Sayang I wasn't knowledgeable pa re: oils at that time.
