Regular oil after using synth? 700

Is it OK to put regular oil in my '91 740 after I've been using synthetic for a while? Do you think its a bad idea?

Also, what are your thoughts on that stuff you pour in with your oil that's supposed to stop minor oil leaks?

Thanks,

Jonathan

Change at 3000 you'll get no sludge! 700

7,500 and you're on your own!
I have 270,000 on mine with 3K oil changes and when I look at the cam all I see is shiney metal- no sludge!

Sludge might not be a bad thing if it fixes my leak :>)

It is OK. No need to use additive, a sludge will begin to form that will impeed leek flow.
