Kung basic lang talaga, eto recommended ko:

EWD
Fire extinguisher
Mechanic's gloves - para matawag mong glove box iyong compartment sa harapan mo
Flashlight
Socket set 1/2 drive like Bluepoint BLPATSM1225
Extended wrench handle 18" with swivel 1/2 drive (like Koken 4769-450) - pang hampas self defense na rin. Plus deep socket na ka-size ng lugnuts mo.
Utility Knife/ Cutter
Hacksaw for metal
Open combi wrench 8x10, 8x11, 12x13, 14x17
screwdriver philips & flat 8"
Flare nut wrench 6, 8, 10, 11, 12 mm - pang repair ng brake/ ABS line
Diagonal Cutting Plier 6"
Long nose Plier 6"
3-tonne hydraulic bottle jack as backup
Jumper cable 400A
5tonne tow cable & 2pcs 2tonne D shackles(adapter since most vehicles have small tow hook in the cassis)
Vinyl electrical tape
Spare fuse
Masking tape
Trash bag - for waterproofing and emergency storage
5L Water in a jug
Brake fluid
Funnel that will fit the fuel lid
Wipe Out hand cleaner/conditioner - para hindi ka na magdadala ng sabon
Lots of rags
Isopropyl alcohol
Kleenex tissue box and some medicines/ first aid kit
Surgical gloves latex
Spork
Can opener

I do lots of long drives so mas mahaba pa dyan ang list ko.
