Octane Booster And My Car/servicing Question Also

[LatinR33]

Hi all i have a R33 skyline the only mod i have is a turboback exhaust and i was wondering should i be using a octane booster?? My car only sees Shell Optimax or BP ultimate. I dont go to the track or drags. Is the 98 RON safe enough or do our cars need to have this additive also. I was also curious with oil changes and services do you guys do it based on the amount of K's the car has done or the date of your last service. thanks guys

No you don't need octane booster. 98 octane should be fine for it.

Oil changes: 5,000kms or 6 months whichever comes first. If you doing highway could stretch it to 10,000km. Use a semi synthetic at least..e.g castrol maganatec or shell helix.. If you really want to then go some full syntheticbut a bit pricey.

Gerabox/Diff oil: 100k kms..If your car came in from japan or unknown history then change them.

Coolant: Every 2 -3 years. Use Nulon or castrol
