TK, regarding sa type or brand of synth oil to use, try to find out which one is readily available in your area para hindi ka mahirapan mag source ng supply mo everytime ka mag change oil. as for the brands you already afore mentioned they're okay naman. royal purp has some good reviews but majority from gasoline engines and a few from diesel engines, repsol as per my experience is a lot of hype to be honest about it. i am currently using motul as like the other members... but i have had a very good history with the brand going back to 6-7 years ago. i can suggest trying castrol as they also have excellent oils. i can go on with the list it can cover a lot of links, so my suggsetion would be for you to stick with the brand that is very accessible in cebu.
also with regards to oil basics and stuff please try to check our threads. i have posted quite a few things there with the very big contributions from some ofour other members, to help and guide members when they get their oils changed as well as basics on oils and stuff.
any other questions just post here or send me an email or PM, i'll be more than happy to help out a member anytime!!
