oil change

[Rods58]

I gave the old grey an oil change castrol 25 x 60 for older engines seeing there is no oil filter how often should you change it "sorry if i sound a bit naive but this is my first grey."

thanks .

every 2000 miles will keep her happy,what i also do seeing there is no oil filter is buy some cheap oil as well, drain your oil ,put in the cheap oil run it 4 about 1 min, drain again then pour in your good oil,I sugest 40-70 penrite.its a thick oil which will keep your pressure up and the motor runs not as loud
