[AT] Switching from non-detergent to detergent oil

[charlie hill]

If it was me, I'd fill the crankcase with diesel fuel and let it sit for 
a few day, dump it out and see what comes out, repeat if necessary,
refill it with detergent oil, run it a few minutes
and dump it and see what the oil looks like and go from there.
But, that's just me.  If you don't want to take the risk just run the 
non-detergent oil.

I just acquired several older Briggs engines. They all run fine but
discovered that the PO was using non-detergent oil.

The manuals all say to use detergent oil.

What can I expect to happen if I switch from non-detergent to
detergent.  Everything else I have uses detergent and I would love to
be able to stock they same type of oil.

Thanks

Dick
