Type: weekend car
Maintenance:
Car cover (the actualy objective is to wash less

),
washing frequency? never fix it, do it whenever is necessary,
NEVER-EVER Change Engine oil more than 4 months OR more than mileage travel indicated,
Send for 3 layers polish + wax (sometime 6 months/8 months),
Wednesday - short ride, Weekend - "some little" boost to do exercise

,
Do not rev high until my engine temperature reach normal
and the list goes on.... ( I believe Ace having much more longer list, hahaha )
Lubricant: Tried
1. Shell Helix Fully Synthetic
2. Shell Helix Semi Synthetic
3. Castrol Semi Synthetic (Current) feel better than SHELL
Wanna try: Motul
Lubricant change, less than 4 months or
Fully synthetic - 10,000KM
Semi synthetic - 7,000KM (some say 6,000KM

)
Others:
I don't do checking (very bad,

), but I use the digital air pump at SHELL (it adjust your tire air pressure, not just pump in) before I take for weekend ride and I'll be very keh-po-chi when my car in workshop, so not every mech like me.
I try to fix problem as soon as I discover it, but at the same time, many mod idea flying in head, with limited budget, things need to be controlled, if not never get marry
