best oil for a petter m universal?
« on: 28 July, 2015, 10:12:18 am »
Have been experimenting with oils for my petter m calibrator. has anyone had some experience with these and can comment on what they can recommend.
smokes a fair bit on 30 weight oil and heavier 40w70 doesn't flow too well.
Cheers keep on tinkering.
Keep on Tinkering :)

Hello all.
Please forgive my ignorance but isn't there a huge difference in viscosities of those two oil grades?

Cheers Scott

I use a SAE30 on the petrol engines as that is just about what was available back then. I use a standard type diesel oil in the diesels.

Hi ,
     Is this engine a 2 stroke or a4 stroke , if a 2 stroke 30 weight oil should be fine 
     Make sure oil feed rate is correct on calibrator oiler and  do these engines have a sump drain  if  so make sure it is operative and if all okay I would not worry about  the smoke if its a 2 stroke a least you know its getting oil , I have seen many an engine fail by reducing oiling to have a smoke free exhaust , my view is oil is cheaper than engine rebuilds

What was special about the plug that you had to buy from UK?
