Well...
...after months of searching the internet regarding any info about my B16A motor, I finally was able to find a workshop manual for it.
The manual seems to have been printed from the UK, although the 1st Gen. B16A is pretty much standard internationally except for North America which did not get a taste of VTEC until the Acura NSX came aboard.
Anyway, recommended motor oil is SE/SF/SG 10W30 from -20C to 32C. Interesting to note that the oil chart is covered in a bit more depth. Here is a quick run-down.
Multi-Grade
5W20: below -30C to -10C
5W30: below -30C to 0C
10W30: -20C to 32C
10W40: -20C to greater than 40C
15W40 & 15W50: -15C to greater than 40C
20W40 & 20W50: -10C to greater than 40C
Straight-Grade
10W: -20C to 0C
20W: -10C to 15C
SAE 20: -5C to 15C
SAE 30: 10C to 32C
SAE 40: 25C to greater than 40C
Now, this chart is compared to the US version of the manual for the B18A Non-VTEC and B17A VTEC which are fairly similar to the B16A except for the displacement difference (B16=1.6L, B18=1.8L, B17=1.7L).
For the B18A Non-VTEC, the recommended oil is as follows:
Multi-Grade only
5W30: below -20C to greater than 40C (Recommended by manual)
10W30: -15C to greater than 40C
For the B17A VTEC
5W30: below -20C to 0C
10W30: -20C to greater than 40C (Recommended)
I currently own a 1991 Canadian Acura Integra with a swapped B16A from a Japanese Integra. The North American Integra (1990-1993) is supplied by either a B18A Non-VTEC or B17A VTEC motor. Outside of North America, the Integra is known as the Honda Integra (1989-1992), and is equipped with a ZC Non-VTEC 1.6L or B16A VTEC motor.
So, I'm not wasting my time then using 5W40 for my B16A
I just thought it interesting how non-North Americans think.
