Oil Weight and Capacity on Old Honda HT3813

[xwhaler]

Going to change the oil in it next weekend. Wondering what weight oil to use (run in 60-90 degree New Hampshire spring/summer/falls)

This engine is water cooled and runs pretty decent (no more smoke than normal)
Is approx 25 years old.
Also, if anoyone knows how much oil this takes let me know as I no longer have the manual.

Thanks in advance.

Forgot to add that this is a Liquid Cooled, 2 cylinder, 13 HP motor.

I would guess a 10w/ 30 or 40 or 15w/40 or 50 would work.

I have an older Honda riding mower and the manual for that calls for 10w-40

You can lookup the owners manual here. But it doesn't tell you a whole lot.

Those are amazing lawn tractor engines. Like a little inline 2cyl OHC vehicle engine. Expensive buggers to maintain and fix though. Pretty much why Honda lawn/garden tractors are no longer I presume.
