may question lang po ako. gaano b katagal ang maximum milage bago magpalit ng langis kapag synthetic? halimbawa, ang car ko is a weekend car lang. is it recommendable na mileage bago ko palitan? mga 15000 kms, ok n kaya yun?
about naman sa headlight, baka may alam kayo kung saan pwede ipalinis yung headlight ng Civic 96? Kasi madumi na talaga.how about yung mga higher watt-age na headlamp bulb, di ba kelangan ng relay duon? meron bang nabibili na snap-on na relay?i want to maintain yung original na wiring ng kotse ko e.
whether or not it's a weekend car or not, the milage should still be the determining factor in replacing the oil. like it has been said in various other threads, kung mineral oil gamit mo, try to replace it by 5000 kms. kung semi or synthetic then you can shoot for a bit higher lke 10k. pero 15000 is kinda pushing it na.
re: headlights. madami meron sa banawe na replacement headlights for like 2800-3000 for the set na ata. this may be a better way to get the lights back to good shape kasi once umitim na yung plastic there is very little you can do by cleaning to get it back to good shape.
ooops. i forgot to tell you guys, i use fully synthetic motor oil. medyo mahal din kasi yun.actually, i change oil every ten thousand along with the filter. may nabasa ako dati, ang synthetic motor oil daw pwede kahit hanggang 50000 kms. eniwei, sobra na yun. baka may alam kayo kung saan nakakabili ng K&N drop-in type na air filter? i might be needing it soon na rin.
