What oil grade would a 1985 Isuzu hatchback 1.5 liter I mark use? I mean, orginal factory recommeneed? was it 10W30? I had this little cool car when i was a teen, and now my neighbor has accuried one! So talking over it, we didint know, and are both curious..:)
The 10W-30 would be a good choice.

0 to 59°F......10W
Above 0°F......10W-30
Above 41°F......30
Above 19°F......20W-20, 20W-40, 20W-50
Below 59°F......5W-30
Below 19°F......5W-20
Manual Transmission,.....SJ
